The pathogenesis of
iron deficiency anemia
associated with amylophagia is usually attributed to dietary iron lack. However, large quantities of starch may inhibit intestinal iron absorption. Accordingly, studies were carried out to determine the effect of laundry starch on the intestinal absorption of inorganic and hemoglobin iron. In vitro, laundry starch bound 19 to 80% of the available 59FeSO4 and 34 to 68% of the available 59Fe-hemoglobin. Binding of both forms of iron was pH-dependent, with maximal binding at pH 7.0. In vivo, laundry starch significantly inhibited mucosal uptake of 59FeSO4 from isolated duodenal loops. In nonanemic rats, administration of laundry starch (100 mg) 1 hr before a 100-mug dose of 59FeSO4 significantly decreased the absorption of 59FeSO4, as compared to saline or low iron chow controls (6.2 +/- 2.0 versus 14.9 +/- 2.1 and -1.8 +/- 1.7, respectively, P less than 0.001). In anemic rats the absorption of either a 100-mug dose of 59FeSO4 or a 500-mug dose of 59Fe-hemoglobin was also significantly decreased by prior administration of laundry starch. The data obtained indicated that laundry starch (1) binds appreciable quantities of inorganic and hemoglobin iron in vitro; (2) inhibits the mucosal uptake or inorganic iron by isolated intestinal loops; (3) inhibits the intestinal absorption of inorganic iron in normal nonanemic rats, and (4) blunts the compensatory increase in inorganic and organic iron absorption in anemic rats.

In a coastal population in whom anaemia was common, two randomised controlled trials were undertaken to investigate the effectiveness of treating
iron deficiency anaemia
at a dispensary and at primary schools. For anaemic adult villagers treated at a dispensary, one dose of tetrachlorethylene for hookworm infection and a once per week visit to collect medicines were found to be satisfactory. A small but significant increase in haemoglobin level was produced by four weeks oral iron therapy, but this was only maintained after seven months by the group that had initially also received tetrachlorethylene. In children (5-14 years) no significant rise in haemoglobin level was obtained by using oral iron and/or TCE, either at the dispensary or at the primary schools. This suggests that malaria was a more potent cause of anaemia in these children.

Pulmonary studies including the measurements of single-breath diffusing capacity for carbon monoxide (DL); Forced Vital Capacity (FVC); Residual Volume (RV) and Total Lung Capacity (TLC) were carried out in forty normal subjects; twelve patients with homozygous sickle cell anaemia and five patients with
iron deficiency anaemia
due to hookworm infestation. Normal subjects had a mean haemoglobin content of 13.4 g per 100 ml and a mean DL value of 28 ml/min/mmHg. In the patients with hookworm anaemia, the mean haemoglobin was 4.9 g per 100 ml while the mean DL value was 9 ml/min per mmHg. Patients with sickle cell anaemia had a mean haemoglobin content of 6.2 g/100 ml yet the mean DL value was 20 ml/min per mmHg. The study showed that patients with homozygous sickle cell anaemia have a disproportionately high DL value in the presence of severe anaemia which might be due to a chronically expanded pulmonary capillary blood volume as a compensatory mechanism to maintain an appropriate level of DL.

Vitamin B12 and vitamin B12 binding proteins were determined in 20 patients with
iron deficiency anaemia
who showed low haemoglobin, haematocrit, serum iron levels and hypochromic microcytic red blood cells. The serum vitamin B12 levels in these patients were significantly lower than that of the normal subjects. Nine of 20 patients had serum vitamin B12 less than 350 pg/ml. There was a significant increase in serum UBBC and TBBC levels in patient group and 9 of 20 patients had higher UBBC values than those of the normal subjects. The absolute values of TCI and TCII increased significantly while TCIII was within the normal limit even though the percentage of UBBC were not different from that of the normal subjects.

Red cell volume distribution curves have been used to measure microcytosis and anisocytosis in normal subjects, blood donors and patients with
iron deficiency anaemia
. These measurements were more sensitive than the conventional red cell indices for detecting blood donors with a low transferrin saturation. Three stages are suggested as iron deficiency progressively interferes with haemopoietic function. Anisocytosis and an increased percentage of microcytic cells are the first haematological abnormalities to occur and at this stage haemoglobin concentration is usually normal and trasferrin saturation less than 32%. At the second stage the MCV and MCH decline, haemoglobin concentration is generally sub-normal, though not below 9 g/dl, and transferrin saturation is usually below 16%. The final stage of iron deficiency is associated with a low MCHC, a haemoglobin concentration below 9 g/dl and a transferrin saturation of less than 16%.

In 90 postmenopausal women aged 55 or older residing in health care facilities, a survey was made of hemoglobin levels and food habits that reflected their consumption of iron-rich foods. The reasons for inadequate dietary intakes of iron are discussed. There is need for better understanding of iron metabolism. Recommendations are made for the prevention of
iron deficiency anemia
in postmenopausal women and for achievement of the highest possible level of health as affected by the intake of iron and related nutritional factors.

There was no significant difference between the assessments by two groups of randomly-selected general practitioners on the effectiveness of the drug treatment for 19 common clinical conditions. The treatment of simple
iron deficiency anaemia
was considered the most effective and gained the highest consensus. Least effective, but not matched by worst consensus, was the drug treatment for obesity. The most widespread disagreement among the practitioners was for the effectiveness of the drug treatment of gastroenteritis.

Brunner's gland adenoma in the third portion of the duodenum is rare and only two such cases have been reported previously. A 35-year old man presented with high-output congestive heart failure. Profound
iron deficiency anemia
was corrected by transfusion, allowing detection of a duodenal tumor, which proved pathologically to be a Brunner's gland adenoma.

Diagnosis is often overlooked because symptoms develop slowly and insidiously and many patients don't complain about them. Then too, the giddiness, apathy, confusion, clumsiness, and similar problems may be considered simply signs of "old age."
Iron deficiency anemia
is the most common type in old people. It's usually due to gastrointestinal bleeding, but there may be a second, less obvious cause. The classic picture of low serum iron, high total iron-binding capacity, and low iron-binding saturation is sometimes distorted. Usually, many studies are needed to confirm the suspicion of a vitamin B12 or folic acid deficiency. A raised mean corpuscular volume in itself signals the need for further investigation. In patients with macrocytosis, the bone marrow must be examined. Tests for intestinal malabsorption must be considered too. Repeated blood tests are essential in patients being treated for any type of anemia. Iron deficiency may hide evidence of folate or B12 deficiency. And iron therapy may lessen bleeding from colonic cancer, delaying diagnosis until it's too late to operate.

Porotic hyperostosis was observed in 34 percent of 539 crania excavated from sites in Arizona and New Mexico. Common causes of this cranial pathology in the Old World (thalassemia, sickel cell anemia, and malargia) do not explain its occurrence in the American Southwest, as malaria and hemoglobinopathies are not known to have existed in the New World prior to European contact.
Iron deficiency anemia
which may also be assoicated with porotic hyperostosis occurs on a mass level only with hookworm infestation or nutritionally-related iron deficiency. Since hookworm infestation is rare in the American southwest and has not been reported in prehistoric southwestern American Indians, the hypothesis of nutritional anemia was examined. In canyon bottom sites where the diet was heavily dependent on maize, which is low in iron and also contains an inhibitor of iron absorption, significantly more crania had porotic hyperostosis than in sage plain sites, where the diet included ample animal protein rich in easily absorbable iron (p less than .001). Furthermore, canyon bottom children, who were more susceptible to
iron deficiency anemia
, had a higher incidence of porotic hyperostosis lesions than adults (p less than .0001).
