Resting and bicycle ergometric ECGs were examined in 159 patients with iron deficiency anemia, including 100 treated with iron-containing drugs. ST segment depression in the patients undergoing exercise was regarded as a sign of silent myocardial ischemia which is common in anemic patients, its detection rate increases as the disease progresses. In patients with iron deficiency anemia, silent myocardial ischemia results in a substantial decrease of threshold intensity, has a negative effect on cardiac output both at rest and during exercise, and significantly slows down the recovery of cardiac performance during therapy. This should be borne in mind while solving problems in medial labour examinations and making rehabilitative measures in patients with the above abnormality.

Serum proteins, serum iron and total iron binding capacity were estimated in 50 patients with oral submucous fibrosis and 50 patients with oral leukoplakia. The values were compared with that of 50 age- and sex-matched controls. A significant depression in hemoglobin and serum iron was observed in both groups of patients, whereas total iron binding capacity showed significant change only in the oral submucous fibrosis patients. Serum protein values were significantly lower in all the patients. The role of iron deficiency anemia in the causation of this premalignant lesion is discussed.

55 patients with iron deficiency anemia (IDA) and 55 age- and sex-matched control subjects were given exercise test on a treadmill to observe the effect on ST segment of the electrocardiogram. 14 IDA patients showed significant ST segment depression compared to only 1 in the control group, the difference being highly significant (p less than 0.001). Test was repeated 2-3 days later in 12 IDA cases and it showed significant ST depression as on previous occasions showing the reproducibility of the results. 11 of these patients received total dose i.v. iron-dextran and the exercise test was repeated 2-3 days later before any significant rise in the hemoglobin level; in 10 cases there was no significant ST segment depression. Response to iron therapy was highly significant (p less than 0.003). Correction of electrophysiological abnormalities of the heart in IDA patients by iron therapy, before the rise of hemoglobin, may be the result of the effect of iron at the tissue level.

Rhesus monkeys were fed a diet marginally deficient in zinc (4 ppm zinc) throughout pregnancy and were monitored for changes in hematological, biochemical, and immunological parameters. This dietary zinc level was chosen because it did not produce an overt deficiency syndrome when fed for 10 wk to nonpregnant monkeys. Deprived animals were compared to control groups fed a zinc replete (100 ppm) diet ad libitum or on a food restricted (pair fed) basis. Beginning in the 3rd trimester zinc-deprived monkeys exhibited characteristic signs of deficiency including dermatitis, anorexia, and low levels of plasma zinc (less than 65 micrograms/100 ml) and of serum alkaline phosphatase activity. The extent of plasma zinc depression in deficient monkeys was dependent on total food intake; severely anorexic monkeys lost weight but maintained normal plasma zinc levels; monkeys that gained 20 to 30% of their body weight during pregnancy had severely depressed plasma zinc. Plasma vitamin A was reduced in the deprived group while copper, magnesium, and folate levels remained similar to controls. Hematological changes indicative of iron deficiency anemia (reduced packed cell volume, mean corpuscular volume, and Hb) were also seen in severely deficient monkeys. In addition, the peripheral lymphocyte mitogen response was reduced in deficient dams. We conclude that marginal deficiency of dietary zinc can produce significant abnormalities of nutritional status and has the potential for producing serious immunohematological dysfunction during pregnancy.

There is little absolute data in the form of prospective studies in patients with specific illnesses who are on oral contraceptives (OCs). Consequently, the clinician must depend on well-founded empiric decisions in prescribing the pill for these patients. The basis for the decision should be a firm understanding of the pathophysiology and laboratory effects of OCs. This needs to be juxtaposed with an understanding of the efficacy and effects of the estrogen and progestational components of the birth control pill and their interactions with maintenance medications. Available evidence is reviewed for the following medical disorders: central nervous system disorders (depression, Wilson's disease, headaches, epilepsy, multiple sclerosis, and the eye); immunologic and connective tissue diseases; diseases of the endocrine system, the gastrointestinal system, the genitourinary system, the memopoietic system; and skin disorders. 7% of women on OCs have increased or newly reported depression. Whether these are primarily psychogenic or metabolically derived is yet to be definitively determined. Wilson's disease can be exacerbated by OCs because of increased plasma ceruloplasmin and increased absorption of copper from the gastrointestinal tract. Headaches can be either a vague or a specific symptom, such as migraines, but 1/3 of these patients will become worse on OCs. There is good evidence that the headaches are caused by falling estrogen levels. There is no good evidence that epilepsy, in general, becomes worse on OCs. OCs have relatively no effect on the longterm prognosis in multiple sclerosis. Increased corneal sensitivity has been observed with OC use, and this has usually presented an intolerance to the use of contact lenses. This is primarily the result of increased edema of the cornea and changing of its contour. By inference, OCs cause some basic universal changes in the immunologic system. OCs have been reported as a cause of a rare form of rheumatoid arthritis, but the Royal College reports a decrease in incidence of cell-mediated immunologic disease, specifically rheumatoid arthritis in its more familiar form. There is no evidence that OCs markedly influence thyroid disease, but they do markedly alter thyroid function testing. OCs do not produce a chronic addisonian state nor do they inhibit the ability of the adrenal-pituitary axis to respond to stress. OCs can be used in thyroid disease but with some caution in hypothyroid states. They should not be used in patients with Cushing's syndrome and are not recommended in patients with adenomas. In general, estrogen works as an irritant to the gastric mucosa, but there is no increase in peptic ulcer diseases associated with OC use, and the incidence of duodenal ulcer disease is decreased. The most striking liver disease seen with OCs is cholelithiasis. The incidence is increased 2-fold. OCs should not be prescribed for patients with chronic renal disease because of the vascular effects as well as the reported increased risk of urinary tract infection. The Royal College report has shown a decreased incidence of iron deficiency anemia in patients on OCs. Various skin changes have been reported in women using OCs. The most common of these is chloasma. In all the diseases studied thus far, the use of OCs has not precipitated a catastrophic change.

It is the aim of this article to provide an overview of difficulties in children with poor growth enrolled in an intensive community intervention trial for failure to thrive (FTT). Children were assessed for developmental delay (Bayley test), inadequate diet, iron deficiency, eating and other behavioural problems, and maternal anxiety and depression (HAD Scales). Sixty-three children aged 6 months to 2 1/2 years were studied. The majority of children were from families living in poverty with many from divorced, separated or single families. On developmental testing (Bayley Developmental Scales) 55% were delayed, 27% severely. Seventy-seven per cent had caloric intakes below the expected average requirement (EAR) with 19% reported at less than 50% of requirements. Iron intakes were similarly low and one-third had iron deficiency anaemia on testing. Sixty per cent of children were reported to have eating difficulties, principally in terms of responding negatively to food. Eating difficulties had commonly presented within the first weeks of life. Other behavioural and sleeping difficulties were also common. Children identified as failing to thrive in the community are likely to have associated developmental, dietary and behavioural problems which may not be immediately evident and to an extent which may require intensive multidisciplinary involvement.

The obstetric course and neonatal outcome were studied in 35 pregnant women with neuropsychiatric disorders who were admitted to Toho University Ohmori Hospital between 1981 and 1990. The rate of live births associated with psychiatric disease was 0.49% (40 of 8.191 deliveries). These were schizophrenia (N = 17), epilepsy (N = 12), depression (N = 2), neurosis (N = 3) and psychogenic response (N = 1). Iron deficiency anemia was observed in 8 of 16 epileptic women. Cesarean section or vacuum extraction were performed in 15 of 40 cases (37.5%). The indications for these procedures were uncontrollable psychotic symptoms in all of 6 schizophrenic women, while those in all 7 epileptic women were obstetrical. Symptoms of schizophrenia became worse in 33.3% and 50% of the patients during and after birth, respectively. The incidence of preterm delivery was 15%, and 25% of newborn infants were of low birthweight. Drug withdrawal symptoms were observed in 4 of 16 infants (25%) born to epileptic mothers. Three of 10 offspring of epileptic mothers were affected by febrile convulsions within 6 years of age. Although a relatively higher incidence of obstetric complications has recognized, there seem to be no specific complications in epileptic or psychiatric women. Our results also suggest the importance and need for close cooperation between the obstetrician and psychiatrist, and a follow-up program for offspring.

Previous studies of dopamine metabolism in iron-deficient rats demonstrated an elevation in extraneuronal levels of dopamine and a depression in the number of dopamine D2 receptors; however, the importance of anemia per se and the reversibility of these observations are not completely resolved. The purpose of this study was to determine if in vivo reuptake of caudate dopamine is altered by iron deficiency anemia, if it is reversible with iron therapy, and if anemia per se produced the same effects on dopamine metabolism. Male Sprague-Dawley rats (21-d old) were fed an iron-deficient diet (4 mg Fe/kg diet) and then iron repleted (5 mg iron dextran), or were fed an iron adequate diet (35 mg Fe/kg diet) and then given phenylhydrazine to induce hemolytic anemia. In vivo microdialysis was performed in steady-state conditions both before and after iron or no therapy and was followed by an intraperitoneal injection of a dopamine reuptake blocker (cocaine-HCl 30 mg/kg). Thirty percent higher extracellular dopamine levels in the caudate-putamen were observed in iron-deficient rats compared with control rats, but no differences were observed in tissue levels. Hemolytic anemic and iron-repleted rats had normal extracellular dopamine levels. The response to dopamine reuptake blockade was significantly attenuated in iron-deficient rats compared with control, iron-repleted, or hemolytic anemic rats. These experiments provide evidence that iron deficiency blunts the dopamine reuptake mechanism, that this is a reversible process in postweaning rats, and that anemia per se does not cause the increased extracellular dopamine levels.

A 20-year-old Hispanic female had 3 episodes of blood in her bowel movements, anal itching, burning, and constipation, and a history of hemorrhoids, hypothyroidism secondary to thyroiditis, depression, and an attempted suicide 3 months earlier. Family history was remarkable for iron deficiency anemia and hypothyroidism. Complete blood chemistry results indicated that she had vitamin B12 deficiency, but, except depression, did not exhibit other neuropsychiatric symptoms of cobalamin deficiency. A two-part Schiling test indicated that she was not producing adequate or active intrinsic factor, thus she was diagnosed with pernicious anemia and requires 1 mg of vitamin B12 intramuscularly for the rest of her life.

A recent major theory was that a meal high in carbohydrate increased the rate that tryptophan enters the brain, leading to an increase in the level of the neurotransmitter serotonin that modulates mood. Although such a mechanism may be important under laboratory conditions it is unlikely to be of significance following the eating of any typical meal. As little as 2-4% of the calories of a meal as protein will prevent an increased availability of tryptophan. Arguably the food with the greatest impact on mood is chocolate. Those who crave chocolate tend to do so when they feel emotionally low. There have been a series of suggestions that chocolate's mood elevating properties reflect 'drug-like' constituents including anandamines, caffeine, phenylethylamine and magnesium. However, the levels of these substances are so low as to preclude such influences. As all palatable foods stimulate endorphin release in the brain this is the most likely mechanism to account for the elevation of mood. A deficiency of many vitamins is associated with psychological symptoms. In some elderly patients folate deficiency is associated with depression. In four double-blind studies an improvement in thiamine status was associated with improved mood. Iron deficiency anaemia is common, particularly in women, and is associated with apathy, depression and rapid fatigue when exercising.
