The hematologic status of 144 consecutive patients in the United Kingdom with oral disease (69 with recurrent aphthous stomatitis; 75 with other disorders) was examined in an attempt to resolve the controversy as to whether levels of hemoglobin, blood cell numbers and indices, and blood film are adequate in the screening of patients with aphthae. Though hemoglobin levels and red blood cell indices were normal in patients with recurrent aphthous stomatitis, there was still a small minority of patients with deficiencies of iron (low serum ferritin), folate (low red blood cell levels), or vitamin B12 (low serum levels) that would have remained undetected. Full hematologic screening of patients with recurrent aphthous stomatitis thus reveals latent deficiency states, at least in some parts of the world, and there are good reasons for elucidating the underlying cause and correcting these deficiencies, particularly vitamin B12 deficiency. Therapeutic studies are now required to establish the frequency with which deficiencies actually predispose to recurrent aphthous stomatitis.

A drug monitoring study was carried out co-operatively by industry, a university department of clinical pharmacology and a randomly selected sample of general practitioners throughout Italy to collect case history and clinical data on over 10,000 patients with anaemia treated for 2 to 4 months with a preparation containing ferritin plus vitamin B12 co-enzyme and folinic acid. Analysis of the data generated, whilst confirming the effectiveness and tolerability of the study medication, highlighted the usefulness of the research methodology for describing the pattern of use of a drug widely prescribed in general medicine.

A study was performed in 100 subjects to determine the prevalence and cause of anaemia in pregnant Indian women in the Johannesburg area. The geometric mean serum ferritin concentration in all three trimesters of pregnancy was below 12 micrograms/l, with 43.3% of women in the first, 48.6% in the second and 80.0% in the third trimester having concentrations below this value. Estimation of body iron stores revealed a mean deficit of 265 mg iron in subjects in the third trimester, 20% of whom had iron deficiency anaemia. No difference in iron status was demonstrable in subjects from different religious backgrounds. Folate and vitamin B12 nutrition was adequate. Three subjects were diagnosed as being beta-thalassaemia heterozygotes. The findings underline the need for routine iron supplementation of pregnant Indian women in the Johannesburg area.

Androgenetic alopecia (a.A.) occurs quite frequently. Up to 79% of women suffer at least temporarily from varying degrees of intermittent diffuse hair loss in the centro-parietal and/or fronto-temporal regions. A.A. is caused by an androgen excess acting on the hair follicle for prolonged periods of time in the presence of a genetic predisposition. However, often hyperandrogenemia cannot be demonstrated in such patients. 125 women with clinically typical a.A. were investigated prospectively under standardized conditions. Patient age ranged from 18 to 68 years (mean +/- SD: 34 +/- 11.6). Atypical uterine bleeding such as menorrhagia, hypermenorrhea and polymenorrhea were found in 69 women. The hair loss varied between 50 and 400 hairs per day (124 +/- 125). Additional signs of hyperandrogenism, i.e. seborrhea (n = 83), acne (n = 52) and hirsutism (n = 28), were often observed. Basal levels of total and free testosterone (T and FT), dihydro-T (DHT) DHEA-sulfate (DS), delta 4-androstendione (A), 17 alpha-hydroxy-progesterone (17P), cortisol (F), progesterone (P), 17 beta-estradiol (E2), sex hormone binding globuline (SHBG), prolactin (PRL), thyreoidea-stimulating hormone (TSH), ferritin (Fe), vitamin B12 (B12) and folat (Fo) were determined by RIA. FT was also measured by equilibrium dialyses. Different methods of determining bound and unbound T were used; their diagnostic value is discussed in detail. In addition, a combined ACTH/TRH-stimulation test was performed in all patients. Pathologic changes of one parameter were detectable in 26.4% of patients, while 67.2% revealed deviations of two or more indices. Excluding clinically relevant borderline values, only 6.4% of patients were without any abnormalities. The incidence rate of pathologic parameters was as follows: FT in % = 52%, Fe = 42%, PRL = 34%, E2 = 34%, FT in pg = 29%, DHT = 28%, SHBG = 26%, TSH = 20.8%, DS = 19%, T = 14%, 17P = 11%, Fo = 7%, A = 6%, F = 6%, B12 = 5%. Group and individual case analyses revealed significant correlations between (1) the levels of the various androgens, PRL and TSH and (2) the E2, SHBG and FT values; these, in turn, were correlated to (3) the occurrence of certain bleeding anomalies (amount, duration, interval) and corresponding ferritin deficiency. Therapy was directed at normalizing the disturbed estrogen-androgen-balance. Using low-dose antiandrogens, estrogens, prolactin suppressants, corticoids, iron-II-preparations as well as estrogen-containing hair lotions hair loss was arrested in 74 of 104 treated women, while regrowth of hair was accomplished in 16 patients. 14 women did not respond to therapy.

Blood samples from 40 patients with fissured tongue syndrome (FTS) were examined, and the results were compared with those of 20 healthy control subjects. FTS was diagnosed when a) the patient had a fissured tongue with smooth-surfaced papillae (n = 25) or b) the patient had geographic tongue and some relatives had fissured tongue (n = 15). These tongue forms were verified also histologically. To evaluate the possibility of systemic disorders in patients with FTS we determined the whole blood picture and levels of vitamin B12, serum folate, serum ferritin, and immunoglobulins (IgA, IgG, IgM, IgE). None of the patients with FTS nor any of the controls were found to be anaemic. The mean levels of serum vitamin B12, ferritin and folate were, however, slightly lower in the patient group than in the controls. These findings suggest that anaemia does not play a primary role in the aetiology of fissured tongue syndrome. The most striking haematological findings were the decreased thrombocyte and leucocyte counts in patients with fissured tongue syndrome compared with the control subjects. Furthermore, the lymphocyte count and serum IgG were low in the patient group. When the two patient groups were compared no differences were found. These observations are discussed from the standpoint of deficiency in the immunological defence mechanism of patients with fissured tongue syndrome.

Experience with an expert system developed for the purpose of classification of anemias is presented. Input for this system consists of limited demographic information on each patient and the results of the complete blood count, with the incorporation of the results of further chemical testing (serum iron/total iron binding capacity/ferritin and serum B12/serum folate/red blood cell folate), if indicated. Performance of this system is demonstrated using data from 84 patients seen in the authors' laboratory selected either because of a request for evaluation by the attending physician or because of significant anemias. Using this limited input, the system was able to accurately classify 74 of 84 (88%) of cases according to previously established criteria. The output from the system is overread by a pathologist. Future directions are also discussed.

Ultrastructural studies were performed on bone marrow aspirates from three patients with visceral leishmaniasis. The patients were moderately anaemic but showed a suboptimal increase in the absolute reticulocyte count. Serum and red cell folate concentrations and serum vitamin B12 concentrations were normal in all three cases, and serum ferritin concentrations were normal or increased. The bone marrows were hypercellular and showed erythroid hyperplasia; a high proportion of the erythroblasts showed dyserythropoietic changes. Amastigote forms of Leishmania donovani were found within bone marrow macrophages and within occasional neutrophil and eosinophil granulocytes. Electron microscopy showed the presence of many abnormal cells, which probably represented immature erythroblasts with giant lysosomes. These cells were often large, usually contained immature nuclei with relatively little condensed chromatin, had 1-20 electron dense cytoplasmic granules with an average diameter of 0.5 micron, and regularly displayed substantial rhopheocytotic activity. A few abnormal cells and intermediate and late erythroblasts appeared to have been phagocytosed by macrophages. The data indicate that dyserythropoiesis and ineffective erythropoiesis have a role in the pathogenesis of the anaemia of at least some cases of kala-azar.

By studying 516 healthy adults normal reference intervals were established for the Coulter "S" haematological indices with the plasma ferritin, B12, folate and red cell folate in a subgroup of 306. Significant sex related differences were found for all measurements other than MCV, MCH and B12. After allowing for these sex related differences, the effects of age, body size, fasting, smoking, alcohol, exercise and contraceptive pill usage on the parameters studied was defined.

Forty-two healthy young women, less than 16 weeks pregnant, with normal hematologic status, were selected at random to receive either a multivitamin/multimineral with 65 mg of iron or one without iron. During pregnancy and the puerperium, a full hematologic evaluation of the iron, folate and B12 status was performed. Those receiving the multivitamin without iron had significantly lower mean serum ferritin levels (P less than .05). During the study, 9 of these 21 noniron subjects (43%) failed to maintain an acceptable hemoglobin level (greater than 11.0 g/dL) and were medicated with 110 mg ferrous iron daily. Use of the multivitamin/multimineral supplement with iron during pregnancy and for 12 weeks postpartum maintained maternal iron stores, eliminated the need for additional iron medication and prevented the development of iron deficiency anemia. This 36-week longitudinal evaluation demonstrated the need for iron supplementation during pregnancy and for three months postpartum. Measurements of serum ferritin at 16-20 weeks of pregnancy will detect hematologic risk in young pregnant women not identified by usual hematologic assessments. The results of this study show that adequate maternal iron stores during pregnancy and the puerperium cannot be maintained by prevailing dietary patterns and therefore that iron supplementation is essential.

A group of South African lacto-ovovegetarians were studied. They did not differ from a group of control subjects in respect of height, weight, Quetelet index or percentage body fat. Dietary analysis indicated that the vegetarians had significantly higher intakes of folic acid and ascorbic acid, and significantly lower intakes of vitamin B12 and zinc compared with the controls. Vegetarians should give special attention to the intake of certain nutrients such as iron, vitamin B12 and zinc, which may be in a less available form or in lower concentrations in plant foods. Vegetarians had lower serum vitamin B12 levels (not significant in males) and ferritin levels (not significant in females) than the controls. Plasma levels of cholesterol, high-density lipoprotein (HDL) cholesterol and triglycerides did not differ between the two groups.
