    Description / Table of Contents: Zusammenfassung Der therapeutische Effekt verschiedener Diäten mit unterschiedlichen Relationen von lang- und mittelkettigem Fett, Kohlenhydraten und Eiweiß wurde bei zwei Geschwistern mit Hyperlipoproteinämie Typ I untersucht. Eine Normalisierung der TG-Werte konnte trotz extrem fettarmer Kost (〈5 g täglich) nicht erreicht werden, da es infolge der relativ kohlenhydratreichen Diät und wahrscheinlich auch wegen der Gabe von MCT zu einer starken Vermehrung der prä-β-Lipoproteine kam. Da es sich um eine lebenslange Therapie handelt, müssen die Risiken einer normal fetthaltigen Kost — vor allem rezidivierende Pankreatitiden durch die exzessiven Chylomikronenspiegel — gegen die einer fettreduzierten und kohlenhydrat-und MCT-reichen Kost — erhöhtes Atheroskleroserisiko durch Hyperpräbetalipoproteinämie — abgewogen werden. Daher erscheinen uns folgende diätetische Richtlinien sinnvoll: 1. Reduktion des langkettigen Fetts auf weniger als 30 g pro Tag, wobei besonders auf eine genügende Linolsäurezufuhr (4–6 g täglich) zu achten ist. 2. Der Kohlenhydratanteil sollte 50 Kalorienprozent nicht überschreiten und vor allem aus Stärke bestehen. 3. Das so entstehende Kaloriendefizit sollte vor allem durch Protein gedeckt werden, was durch spezielle Eiweißanreicherung einzelner Nahrungsmittel möglich ist. 4. Nur bei Schwierigkeiten bei der Einhaltung der eiweißreichen Kost sollte der Einsatz mittelkettigen Fetts erwogen werden.
    Notes: Summary The therapeutic effect of different diets varying in long chain and medium chain triglycerides, carbohydrate, and protein was tested in two siblings with type I hyperlipoproteinemia. Despite administration of an extremely fat reduced diet (〈5 g daily), a normalization of plasma TG could not be obtained because—as a consequence of its high carbohydrate and/or its MCT content—it resulted in a considerable increase in pre-β-lipoproteins. As life long dietary therapy has to be maintained, the risks of a normal fat containing diet (mainly bouts of pancreatitis) and those of a carbohydrate and MCT rich diet (premature atherosclerosis) are to be carefully considered. On the basis of our data we therefore suggest the following dietary regimen: 1. Reduced intake of long chain triglycerides (less than 30 gms per day), but with sufficient amounts of essential fatty acids (4–6 gms linoleate daily). 2. The carbohydrates should not exceed 50% of total calories and ought to consist mainly of starch. 3. The caloric deficit thus generated should be balanced by a high protein intake. This is facilitated by applying a specially protein-enriched food. 4. Medium chain triglycerides may be necessary when adherence to the protein-rich diet turns out to be bad.

    Notes: Abstract Using electron microscopy, glycogen-filled lysosomes were found in peripheral lymphocytes in 5 cases of the infantile form of glycogenosis type II. In two infants whose blood smears were available, the ultrastructural demonstration of this pathognomonic storage corresponded to well-delineated vacuoles detected by routine light microscopy. Detection of such vacuoles in peripheral lymphocytes by light microscopy and demonstration of glycogenfilled lysosomes by electron microscopy could be a simple and harmless tool for diagnosing the classical form of type II glycogenosis.

    Description / Table of Contents: Zusammenfassung Der klinische Verlauf zweier Patienten mit primärer Hypomagnesämie wird beschrieben. Bei einem Patienten, einem 5 Monate alten Säugling, wurden Magnesiumretention,-resorption,-Stuhlausscheidung und-Clearance gemessen. Die Retention (2,8%) und Resorption (7,8%) von Magnesium28 war deutlich erniedrigt im Vergleich zu Kontrollpersonen, die durchschnittlich 25% retinierten und 28% absorbierten. Zwischen den Retentionswerten der Eltern und Verwandten und denen der gesunden Erwachsenen bestand kein Unterschied. Der untersuchte Patient wurde erfolgreich mit Trimagnesiumdicitrat, entsprechend einer Dosis von 1,75 g Magnesium, behandelt.
    Notes: Abstract The clinical course of 2 patients with primary hypomagnesemia is reported. In one male patien, 5 months old, measurements of magnesium retention, intestinal absorption, fecal excretion and renal clearance were performed. The retention (2.8%) and absorption (7.8%) of 28-Mg were markedly reduced in comparison to controls (average retention 25% and average absorption 28%). The retention values of the parents and other relatives did not differ from those of healthy adults. The examined patient was successfully treated with trimagnesium dicitrate containing 1.75 g magnesium per day.

    Notes: Abstract The selenium content of serum, whole blood and hair was measured by neutron activation analysis in dietetically treated patients with phenylketonuria (PKU) and maple-syrup-urine disease (MSUD). Follow-up studies showed a decrease of the serum selenium content and the glutathione peroxidase activity of erythrocytes—a selenoenzyme—from normal values at the beginning of the diet to 20% (selenium) and 50% (gluthione peroxidase) of normal within 10–12 weeks of dietary treatment. In 36 patients the serum selenium content was lower at 6.7–28×10-9 g/ml, independent of the age of the patients (0.5 to 10 years). The selenium content of whole blood was reduced: median=98×10-9 g/g dry weight; range 75 to 165×10-9 g/g dry weight (healthy children: median=381×10-9 g/g dry weight; range 245 to 588×10-9 g/g dry weight). The selenium content of hair was markedly lower in the patients (median=62×10-9 g/g; range 13–140×10-9 g/g) than in healthy children (median=429; range 213 to 720×10-9 g/g). The mean glutathione peroxidase activity of erythrocytes was reduced to 4.6±0.64 U37/g Hb, in comparison to normal values (mean=8.8±0.88 U37/gHb).

    Notes: Abstract A patient with a progressive neurological disorder beginning at the age of three years is described. Mental and visual disturbances were the first signs, soon followed by ataxia and myoclonic jerks. Fundoscopy revealed a decreased pigmentation of the retina. Ultramicroscopic investigations of muscle and skin disclosed the typical changes seen in the late infantile and juvenile forms of neuronal ceroid-lipofuscinosis. In contrast to the clinical and ultrastructural findings, the fatty acid pattern of the serum lecithin showed a significant increase of arachidonic acid and a corresponding decrease of linoleic acid which is characteristic of the so-called infantile form of neuronal ceroid-lipofuscinosis (Hagberg-Santavuori variant; polyunsaturated fatty acid lipidosis). The obvious heterogeneity of the clinical, histological and laboratory findings within the subgroups of neuronal ceroidlipofuscinosis is briefly discussed.

    Notes: Abstract The selenium content of human milk, cow's milk and cow's milk infant formula were estimated by instrumental neutron activation analysis. The highest values were found in 3 samples of human colostrum (524–865×10-9 g/g dry weight). There was a significant decrease with increasing time post partum. Mature human milk exhibited a selenium content of 230±79×10-9 g/g dry weight. The selenium content of 45 samples of cow's milk from the north-western area of Germany was 200±39×10-9 g/g dry weight. While there was no significant difference between the values of mature human milk and of cow's milk, cow's milk infant formula exhibited significantly (P〈0.01) lower values than human milk. The average selenium content of 107 samples of 10 different commercially available fluid and powdered cow's milk infant formulas (range: 18–171×10-9 g/g dry weight) amounted to about only one third of that in mature human milk.

    Notes: Abstract Serum zinc concentrations in subjects of different ages were estimated by neutron activation analysis to obtain reliable reference values for the diagnosis of primary or secondary zinc deficiency during childhood. In these healthy individuals a small age-dependent variation of the mean values was found. Serum zinc concentrations were lower in cord blood (mean value: 880×10−9 g/ml) and in infants (mean value: 820×10−9 g/ml) than in adults (mean value 1178×10−9 g/ml). In comparison to these values, the serum zinc concentration in a patient with secondary zinc deficiency and 4 patients with acrodermatitis enteropathica was reduced to about 25% of normal.

    Description / Table of Contents: Zusammenfassung Bei 3 Patienten mit Akrodermatitis enteropathica wurde mit Hilfe der Ganzkörpermessung nach oraler Applikation von 65Zn eine verminderte intestinale Zinkresorption gedunden. Dagegen war die Zinkelimination aus dem Körper normal. Die Zinkkonzentration im Serum war bei den Patienten stark erniedrigt. Alle klinischen Symptome verschwanden nach sehr hohen oralen Zinkdosen. Diese Befunde sprechen um so mehr für eine ursächliche Rolle des Zinks in der Pathogenese der Akrodermatitis enteropathica, als bei dieser Krankheit ultrastrukturelle Veränderungen in den Panethschen Zellen nachzuweisen sind [12], die auch beim Zinkmangel der Ratten gefunden wurden [Beitr. Path. 145, 336 (1972)].
    Notes: Abstract The intestinal resorption of zinc using 65ZnCl2 was estimated in 3 patients with acrodermatitis enteropathica, 2 healthy controls, and 3 heterozygotes. After oral application of 65Zn the whole body activity was measured by a whole body counter for 34 days. The 65Zn resorption of the patients amounted to 16, 42 and 30% of the applied dose, whereas the resorption values of the heterozygotes and the controls were in the range of 58 and 77%. The elimination of 65Zn from the body amounted to about 0.7% of the applied dose with no difference between controls and patients with acrodermatitis enteropathica. Before therapy the serum-zinc levels of patients were markedly decreased. After oral application of high doses of zinc aspartate (2×400 mg/day) all clinical symptoms disappeared within a week. The results point at a causal connection between zinc and the pathogenesis of acrodermatitis enteropathica. Ultrastructural alterations of the Paneth cells of the intestine are also shown in this disease [12] as have also been seen in Paneth cells of zinc deficient rats [Beitr. Path. 145, 336 (1972)].

    Notes: Abstract Two patients with severe hypoglycemia since birth are described. In both hyperinsulinism was demonstrated during spontaneous hypoglycemic attacks or could be provoked by various tolerance tests. In case I considerable obesity and psychomotor retardation was present at the age of one year whereas in case II weight gain was normal and development unaffected. Immunofluorescence microscopic and electron microscopic examination of the pancreas after subtotal pancreatectomy revealed diffuse islet cell hyperplasia with nesidioblastosis in case I and β-cell nesidioblastosis in case II. The hyperplastic and nesidioblastotic areas consisted mainly of β-cells. In addition, an accumulation of somatostatin producing cells was observed in case I, and some cells were found with ultrastructural signs of both endocrine and exocrine function. In both cases, pancreatic insulin release was inhibited by a prolonged somatostatin infusion. The results of tolerance tests did not allow a diagnosis of the underlying pancreatic lesion. In case II, leucine-sensitive hypoglycemia detected soon after birth, was present even after subtotal pancreatic resection. Therapeutic trials with diazoxide in case I and a leucine-restricted diet in case II were only of temporary benefit. After subtotal pancreatectomy there was clinical improvement in both cases, but case II still needs a leucine-restricted diet. The familial occurrence of persistent hypoglycemia in both cases suggests that β-cell nesidioblastosis may be a hereditary disorder.

    Notes: Abstract An 11-year old girl with spastic paraplegia and mental retardation has suffered from attacks of metabolic acidosis since the age of 18 months. “Ketotic hyperglycinemia” was diagnosed when she was 3 years old. Reinvestigation at 9 1/2 years included a two-day load with L-isoleucine, and propionyl-CoA carboxylase assay in cultured fibroblasts. The following compounds increased following the load: 3-hydroxypropionic acid, 2-methyl-3-hydroxybutyric acid, 2-ethylhydracrylic acid, 3-hydroxy-n-valeric acid, 3-oxo-n-valeric acid, 2-methyl-3-oxobutyric acid, 2-oxo-3-methylvaleric acid, 2-methyl-3-oxovaleric acid, N-tiglylglycine, methylcitric acid and butanone. Small amounts of alloisoleucine appeared in plasma. Propionyl-CoA carboxylase deficiency was suggested by this metabolite pattern and demonstrated in cultured fibroblasts.
