    Notes: Abstract: A novel methodology which allows for fast and fully automatic structural analysis during preoperative planning for dental implant surgery is presented. This method integrates a fully automatic fast finite element solver within the framework of new concepts in computer-assisted preoperative planning for implant surgery. The planning system including optimized structural planning was validated by experimental results. Nine implants were placed in pig mandibles and mechanically loaded using a testing rig. The resulting displacements were measured and compared with those predicted by numerical analysis during planning. The results show that there were no statistically significant differences (P=0.65) between the results of the models and the experiments. The results show that fast structural analysis can be integrated with surgical planning software allowing the initial axial implant stability to be predicted in real time during planning. It is believed that such a system could be used to select patients for immediate implant loading and, when further developed, be useful in other areas of preoperative surgical planning.

    Description / Table of Contents: Zusammenfassung Der Einfluß angeborener Stoffwechselstörungen auf den Aminosäurengehalt, die Struktur und das Wachstum menschlicher Haare wurde bei Patienten mit Phenylketonurie, Cystinose, Homocystinurie und Tyrosinose untersucht. Rasterelektronenmikroskopische Untersuchungen zeigen bei Phenylketonurie und schweren Cystinosen Cuticuladefekte und -deformierungen in Form eines “Pliseemusters”. Der Aminosäuregehalt des hydrolisierten Haarkeratins ist bei allen Patienten im Normbereich und zeigt keine signifikanten Unterschiede von Phenylalanin, Cystin, Homocystin, Methionin oder Tyrosin. Störungen des Haarwachstums wurden an Hand von standardisierten Trichogrammen erfaßt. Die Ergebnisse zeigen, daß mit zunehmender Schwere der Stoffwechselstörung die Zahl der dystrophischen Haarwurzeln ansteigt.
    Notes: Summary The influence of inborn errors of metabolism on the amino acid content, the structure and growth of human hair has been studied in patients suffering from Phenylketonuria, Cystinosis, Homocystinuria and Tyrosinosis. Examination of hairs under the scanning electron microscope reveals defects and abnormalities such as a plicated pattern of the cuticula in patients with Phenylketonuria and Cystinosis. The amino acid content of the hydrolized hair keratin of all patients was within normal range and did not reveal significant changes of phenylalanine, cystine, homocystine, methionine or tyrosine. Disturbance in hair growth was determined by evaluation of standardized hair root samples. The results indicate an increase in hair root atrophy with increasing severity of the disorder of amino acid metabolism.

    Notes: Abstract Three patients with maple syrup urine disease were treated during the acute neonatal stage. Multiple exchange transfusions proved to be a satisfactory means of achieving rapid clinical and biochemical improvement during this phase. On the other hand, evidence is provided suggesting that in addition to exchange transfusions, a high calorie intake above 150 Cal/kg body weight/day is necessary to lower the plasma concentration of the branched chain amino acids to near-normal levels. As long as this calorie intake was not provided, further exchange transfusions failed to lower the plasma leucine concentration to below 17 mg/100 ml in one patient. It is assumed that this high calorie intake is necessary to prevent the breakdown of endogenous protein. Treatment of acute episodes in maple syrup urine disease should therefore not only eliminate the elevated alpha-keto acids and branched chain amino acids quickly (i.e. by multiple exchange transfusions or peritoneal dialysis), but in addition should provide a high calorie intake.

    Notes: Abstract 8 newborns with early onset group B streptococcal infection and two patients with late onset meningitis were observed during a period of three years. Respiratory distress, early onset of apnoic spells, and roentgenographic signs of hyaline membrane disease or perinatal pneumonia may lead to early diagnosis, especially if shock develops. The fatal course can only be prevented by prompt antibiotic treatment.

    Notes: Summary On adapting brackish waterAnguilla anguilla to fresh water it was noted that, while the plasma sodium, magnesium,pCO2 and pH were held reasonably constant, there was a substantial fall in chloride concentration (−33 mEq). The gradient of the linear correlations between plasma sodium and chloride also fell (brackish water gradient=0.92, fresh water gradient=0.21) indicating that a new pattern of plasma ion interrelationships was being established. Comparison with plasma Na/Cl ion ratios from other fishes suggested that this phenomenon was peculiar toA. anguilla. Corresponding with the very low plasma chloride levels plasma bicarbonate was four to five times that found in other fishes, and this was thought related to the finding that the haematocrit value almost doubled during adaptation to fresh water. In fresh water adapted fish a fall in plasma chloride was associated with a rise in plasma bicarbonate, however the charge compensation effect of this response was only partial as summing the common plasma cations and anions left an anion deficit of about 34 mEq to be accounted for.
