    Notes: Abstract  The purpose of the present study was to de-termine retrospectively the clinical performance of 42 all-ceramic partial crowns (PCCs) placed during the past 7 years. All patients (n=25) with partial ceramic crowns (n=49) placed by one experienced dentist between 1992 and 1999 were asked to take part in a clinical study, and 22 patients with 42 restorations agreed to do so. All partial ceramic crowns studied were fabricated using the IPS-Empress I all-ceramic system (Vivadent). The following luting composites were used for placing the restorations: 20 (47.6%) Variolink high viscosity (Vivadent), 3 (7.1%) Variolink ultra (Vivadent), 17 (40.5%) Dual Zement (Vivadent), and 2 (4.8%) Compolute (Espe). The partial ceramic crowns were examined clinically using the modified USPHS criteria. Of the 42 restorations, 40 (95.2%) were still in function without any need of replacement. One restoration (2.4%) had failed before starting the clinical study, and another one (2.4%) fractured during the study. Twenty-eight (66.7%) of the partial ceramic crowns evaluated were rated Alpha with respect to marginal adaptation. Twelve (28.6%) restorations were rated Bravo, no Charlie ratings were found and 2 (4.7%) restorations were rated Delta. The Kaplan-Meier analysis was used to calculate the survival rate. The probability of survival (95% confidence interval) for 7 years was 81% (66–96%). These data indicate that partial ceramic crowns may provide successful esthetic restorations in posterior teeth.

    Notes: Abstract Pelvic and paraaortal lymph nodes of 499 gynecologic cancer patients were screened for the occurrence of metaplastic changes and their topographic pattern. Glandular inclusions in lymph nodes were distributed evently across all lymphatic areas and there was no correlation to the extent and the kind of carcinoma. In most cases the benign nature of these inclusions was obvious even in the presence of metaplasias and there was no difficulty in differentiating them from metastases.

    Description / Table of Contents: Zusammenfassung Aliphatische Di- und Polysulfide lassen sich im reverse-phase-Verfahren an einer chemisch gebundenen Octadecylphase (Micro-Pak-CH) mit MeOH-H2O als Eluens sauber trennen. Die qualitative Zuordnung der Peaks wird durch folgende Effekte vereinfacht: 1. log k′ nimmt bei konstanter S-Zahl linear mit der C-Zahl zu; 2. log k′ nimmt bei konstantem Alkylrest linear mit der S-Zahl zu; 3. log k′ fällt linear mit zunehmendem Gehalt des Eluens an MeOH. Bei Auswahl eines geeigneten Eluensgradienten können homologe Reihen wie R 2 S 2 mit R = Methyl bis R = Hexyl oder R 2 S x mit x = 2−7 mit einer Auflösung Res ∼ 2 zwischen allen Komponenten getrennt werden. Die Polysulfide werden bei diesen Trennungen nicht verändert.
    Notes: Abstract Aliphatic di- and polysulphides were separated by reverse-phase bonded-phase liquid chromatography. Chemically bonded octadecyl groups formed the stationary phase, mixtures of water and methanol were the mobile phase. For the qualitative analysis of polysulphide mixtures the following findings are important: 1. With constant S-number log k′ increases linearly with the C-number. 2. With constant hydrocarbon group log k′ increases linearly with the S-number. 3. log k′ decreases linearly with increasing methanol percentage in the eluent. With proper choice of gradient homologous series like R 2 S 2 with R = methyl to R = hexyl or R 2Sx with x = 2 ... 7 could be separated with a resolution of about 2 between all components. The polysulphides are not altered during these separations.
