Selenium status of healthy Turkish children.

Selenium concentrations, in blood plasma, red blood cells, hair of 61 healthy children, ages 0-14 yr, were determined using hydride generation atomic absorption spectrometry. Starting from late lactation period, selenium concentrations in all these matrices were found to be increasing with age. A good correlation was found between erythrocyte and plasma, hair and plasma, and hair and erythrocyte selenium concentrations. Although plasma, erythrocyte, and hair selenium concentrations of girls seemed to be higher than that of boys (only in erythrocytes), selenium concentrations of girls were found to be significantly (p < 0.002) higher than that of boys, 71 +/- 9 ng/mL, vs 65 +/- 10 ng/mL, respectively. Selenium status of Turkish children is found to be lower than that found in the literature; marginal selenium deficiency could be important in the development of some selenium deficiency related diseases. There is a need for extension of this study to healthy children from different regions in Turkey and to different disease states.

Infantile acute hemorrhagic edema: a variant of leukocytoclastic vasculitis.

Infantile acute hemorrhagic edema (IAHE) is a leukocytoclastic vasculitis that is confined to the skin without visceral involvement. Edema and purpuric lesions characterize the disease. The disorder has a dramatic onset, with a short, benign course and spontaneous resolution within several weeks. The clinical similarities between IAHE and Henoch-Shönlein purpura have been discussed in the literature. We report three infants with IAHE and discuss the clinical, laboratory, and histopathologic features of the disease. We suggest that it should be regarded as a separate entity for appropriate diagnostic investigations and therapy.

GM-CSF in the treatment of Fanconi's anaemia.

We have used recombinant human (rh) GM-CSF in two 12-year-old Fanconi's aplastic anaemia patients. They had not received any previous therapy except blood transfusions. Each patient was given three 21 d courses of rh-GM-CSF, the first two at a dose of 3.5 micrograms/kg/d and the third at 7 micrograms/kg/d s.c. There were significant increases in WBC and absolute neutrophil counts after the first week of rh-GM-CSF which lasted as long as the treatment was continued. Following the cessation of treatment, WBC and ANC dropped rapidly. We conclude that rh-GM-CSF can be used in FAA, especially in severely neutropenic cases.

Premature thelarche in Kabuki make-up syndrome.

A 2 year old girl who has Kabuki make-up syndrome with isolated premature thelarche is presented. She has unique ocular abnormalities which have not been reported previously. In the literature at least 85 patients, most of them from Japan, have been reported. This is the first reported non-Japanese Asian case.

High risk subgroup of acute myelomonocytic leukemia (AMML) with orbito-ocular granulocytic sarcoma (OOGS) in Turkish children. Retrospective analysis of clinical, hematological, ultrastructural and therapeutical findings of thirty-three OOGS.

Thirty-three patients presenting with orbito-ocular granulocytic sarcoma (OOGS) and acute myelomonocytic leukemia (AMML) were diagnosed in Turkish children from 1963 to 1983. OOGS, characterized by exophthalmos, chemosis and orbital masses, was observed in 33 (27.2%) of 121 AML patients compared with 41 children of AMML without ophthalmic tumors during the same period. Eye tumor and bone marrow aspirates were also studied under light and electron microscopies. The comparison of the hematological parameters did not indicate any statistical difference between the groups. Despite similar chemotherapy regimens administered to all patients, the mean survival time was 8.7 months in the OOGS group, which is significantly shorter compared to those without OOGS (28.6 months) (p less than 0.01). These cases may be classified as a "high risk" subgroup of childhood AMML.

Zinc and anergy in pediatric Hodgkin's disease in Turkey.

Blood (serum, erythrocytes) and hair zinc levels were determined in 60 biopsy-proven pediatric Hodgkin's disease cases at diagnosis. Cellular immunity also was assessed through total lymphocyte counts, E-rosette formation, lymphoproliferative response (LP), and delayed cutaneous hypersensitivity tests to dinitrochlorobenzene, streptokinase-streptodornase, purified protein derivative and phytohemagglutinin (PHA) in some of these patients. Interestingly, anergic patients unresponsive to four antigens showed significantly more depressed serum zinc levels as well as decreased lymphoproliferative response to mitogen (PHA). A positive correlation could be shown between serum zinc level, cutaneous anergy and LP. A possible contributing role of zinc deficiency in defective cell mediated immunity in Hodgkin's disease was proposed, and administration of oral zinc, as a natural immunostimulant is considered in this lymphoma.

Effects of zinc supplementation on linear growth in beta-thalassemia (a new approach).

Linear growth was evaluated in 32 patients with beta-thalassemia major. At the beginning of the study of 40.6% of the patients were below the 10th percentile with biochemical evidence of zinc deficiency. Effects of zinc supplementation on growth velocity (height) were assessed in a controlled manner. Twenty-one children received oral zinc sulphate for a period of 1 to 7 years (15 early- and 6 late-supplemented cases), while the remaining 11 thalassemics were maintained only on conventional transfusion therapy. The mean height velocity of early-zinc supplemented children was significantly greater than that of normal children (P less than 0.01). An increase in height was also observed in the patients who received delayed zinc retardation. The present study demonstrated that zinc deficiency is one of the factors responsible for retarded linear growth in beta-thalassemia major. Only the patients who received zinc supplementation showed an acceleration of growth in height. Administration of zinc could, therefore, be considered as an effective adjuvant therapy in homozygous beta-thalassemia.

Facioscapulohumeral muscular dystrophy concentrated in the village Cullar, Nevşehir, Turkey.

In this paper genetic, clinical, and epidemiological studies on a muscular dystrophy which originated and is concentrated in the village of Cullar, Nevşehir of inland Turkey, are reported. A pedigree chart has been constructed by careful and repeated inquiries, and both clinical and laboratory examinations have generally been carried out in the field. The condition, facioscapulohumeral muscular dystrophy of Landouzy-Déjérine, has been found to have affected at least 53 individuals, 9 of whom are deceased. Both sexes in six generations are involved as would be expected from a dominant mendelian gene freshly mutated at least 100 years ago. Additionally, some 19 individuals have been described as having the disease or some of its stigmata, but have not been examined by us. Initial signs and symptoms seem to appear early in infancy, though variable, and because of complete dominance, some 75 individuals are at risk. The disease progresses slowly without interfering significantly with survival and reproduction. For prevention the so-called Cullar example measures have been taken to improve the area culturally and socioeconomically.

Geophagia in Turkey: iron and zinc deficiency, iron and zinc absorption studies and response to treatment with zinc in geophagia cases.

A brief summary of the research carried out on the problem of geophagia is reported in this paper. Geophagia was a common finding among Turkish children and women in villages, associated with severe iron deficiency anemia in addition to zinc depletion. The syndrome characterized by geophagia, iron deficiency anemia, growth retardation, hypogonadism and zinc deficiency has been observed in both sexes in Turkey for several decades. Zinc deficiency has been also shown by our group in this syndrome. The decreased concentrations of zinc in serum, plasma, RBC, hair and urine were measured by atomic absorption spectrophotometer. Oral iron (both inorganic and radioactive iron) and zinc absorption tests were carried out with and without clay and revealed decreased iron and zinc absorption in some cases with prolonged geophagia. Therefore, malabsorption of iron and zinc was considered to be an additional and/or a new finding in the syndrome. Furthermore, Turkish clay most probably inhibits zinc absorption in a way similar to its inhibition of iron absorption. It was worthy of observation that some Turkish patients with this syndrome had a thalassemia-like appearance with similar skull-bone changes. Finally, growth retardation and delayed puberty were shown to be corrected by oral zinc treatment for 6-month terms. Linear growth and sexual maturation were found to be greater in the zinc-treated group than in the controls.
