    Notes: Abstract The nutrient intake of 69 stone formers (SFs) from three subsets of the local population (urban 22, rural tribal 22 and rural nontribal 25) and 69 age, sex, weight and socioeconomically matched control subjects (NSs) (urban 20, rural tribal 22 and rural nontribal 27) was studied. Simultaneously their timed 24-h urine samples collected over a similar period were analyzed. In general caloric and protein intake was low in all the groups but was strikingly low in the rural subjects. Intake of all nutrients was lowest in the tribal group. Although no difference was observed in diet between NSs and SFs in the same population subjects, SFs had higher urinary excretion of oxalic acid and calcium and lower excretion of citric acid and excreted more saturated urine. Notably magnesium intake was normal in both NSs and SFs, but mean excretion of magnesium was lower than normal in all the groups, suggesting its defective absorption. The influence of dietary intake of protein, carbohydrate, fat, fiber, calcium and oxalic acid on urinary excretion of calcium, oxalic acid, uric acid, inorganic phosphorus, magnesium and citric acid was examined using the chi-square test. No association was observed, thus suggesting that this low nutrient intake did not influence the lithogenic process. Thus, the overall observations suggest: (a) poor nutrition, (b) no effect of diet on urinary stone disease, (c) no difference in the nutrient intake between NSs and SFs and (d) a higher excretion of promoters and a lower excretion of inhibitors in SFs than in NSs.

    Notes: Abstract Intestinal volvulus causing obstruction is an unusual complication of ventriculoperitoneal shunts. There are no clear guidelines on the management of this problem. In our patient exteriorization of the shunt with subsequent reinsertion at a different site led to an uneventful recovery. The extreme rarity of this complication and its challenging management are discussed.

    Description / Table of Contents: Quantitative „Softness“ Parameter und ihre Anwendung in der Strukturaufklärung von Bimetalltetracyanat-Komplexen〉2M(NCS)2M′(SCN)2〈 und [Ml6][M′(SCN)4], (M = COII und NiII; M′ = ZnII, CdII und HgII, L = Anilin, p-Toluidin, Pyridin, Nicotinamid, 2,2′-Bipyridin und 4-Aminopyridin) wurden dargestellt und charackterisiert. Die Strukturen werden auf Grund von Leitfähigkeits-, magnetischen und spektroskopischen (IR und VIS) Messungen, sowie durch gruppentheoretische Berechnungen und Ligandenfeldparametern vorgeschlagen. Diese Strukturvorschläge werden gestützt durch quantitative „Softness“ - Werte „\documentclass{article}\pagestyle{empty}\begin{document}$ {\rm E}_{\rm n}^{_ + ^ +},{\rm E}_{\rm m}^{_{\rm +}^{\rm +}} $\end{document}“. Die totale „Softness“ von M und M′ und ihre Differenz \documentclass{article}\pagestyle{empty}\begin{document}$ \Delta {\rm TE}_{\rm n}^{_ + ^ +} \left({{\rm M} - {\rm M}'} \right) $\end{document} wurden abgeleitet (Gleichungen siehe Abstract) und mit der Struktur der Komplexe in Verbindung gebracht.

Their structure have been proposed on the basis of molar conductance, magnetic moment, group theoretical calculations, ligand field parameters, infrared and electronic spectral studies. The proposed structures have also been supported by quantitative values of softness „\documentclass{article}\pagestyle{empty}\begin{document}$ {\rm E}_{\rm n}^{_ + ^ +},{\rm E}_{\rm m}^{_{\rm +}^{\rm +}} $\end{document}“,.

    Notes: Indium(III) and tin(IV) thiocarboxylates were prepared and characterized on the basis of their IR, 13C- and 19Sn-NMR data. Indium tris(thiobenzoate) (1) decomposes into a sulfido complex In (S)[S(O)CPh] (2a). The corresponding tris(thioacetate) In[S(O)CMe]3 is thermally too unstable to be isolated. The anionic tetrakis complex [Et3NH]{In[S(O)CPh]4} (3) was characterized by X-ray crystallography which revealed a distorted tetrahedral coordination at the In atom. X-ray diffraction analysis of the complexes BuSn[S(O)CPh]3 (4) and Cl2Sn[S(O)CPh]2 (7) showed distorted tetrahedral and cis-octahedral structures, respectively.
