A completely digital workflow for an interim implant-supported crown: A clinical report.

This article describes a completely digital workflow for the diagnostic phase, surgical and prosthetic planning, extraction, immediate single implant placement by guided surgery, and interim implant-supported crown. From a virtual impression, zirconia abutments and a polymethylmethacrylate (PMMA) interim crown was planned in a computer-aided design (CAD) software program. This workflow shortened the time required for chairside placement of an interim restoration with enhanced function and esthetics while restoring an anterior mandibular tooth lost after trauma.

Human immunodeficiency virus type 1 and related primate lentiviruses engage clathrin through Gag-Pol or Gag.

The Gag-Pol polyprotein of human immunodeficiency virus type 1 (HIV-1) is not required for efficient viral particle production. However, premature termination codons in pol, particularly in the integrase (IN)-coding region, can markedly impair HIV-1 particle formation, apparently due to the premature activation of the viral protease (PR). We now report that the IN domain of Gag-Pol is required for the incorporation of clathrin into HIV-1 virions.

Novel use of a fiber-optic-based on-line trichloroethylene sensor in a column retardation experiment.

A newly developed fiber-optic-based trichloroethylene (TCE) sensor previously described [F.P. Milanovich, S.

[Mitral valve endocarditis caused by Salmonella enteritidis].

The epidemiology of salmonellosis has undergone a change during the last 2 years. An increase in the number of cases of enteritis and sepsis caused by Salmonella enteritidis has been observed. We report on the case of a 65-year-old woman with mitral valve endocarditis due to Salmonella enteritidis.

Bacteremia during extracorporeal shock wave lithotripsy of renal calculi.

An increasing incidence of bacterial endocarditis has been observed since the beginning of the last decade. An explanation for this fact is the expansion of diagnostic and therapeutic procedures in diverse medical disciplines. In a clinical study performed on 49 consecutive patients undergoing extracorporeal shock wave lithotripsy a 14.

[Bone banks in the FRG. Results of a survey].

In a nationwide survey, 1350 departments of general surgery, trauma surgery, and orthopedic surgery were approached in an attempt to determine how many surgeons use bone grafts and how they manage their bone banks; 961 responded to the postal enquiry. Bone banks are currently in use in 471 departments. The storage temperature varies between 0 degrees C and -30 degrees C in more than 50%.

Microbial spectrum of blood and body cultures in febrile episodes of children under chemotherapy for treatment of malignant diseases.

One hundred thirty-five febrile episodes in 111 children with malignancies were reviewed. In 50 of 125 episodes blood cultures were positive; gram-positive bacteremia was detected in 40 episodes and gram-negative bacteremia in 10 episodes. The predominant gram-positive bacteria were coagulase-negative staphylococci, the predominant gram-negative bacteria were Escherichia coli.

Experimental studies with absorbable and nonabsorbable sutures in infected canine arterial anastomoses.

Vascular anastomoses are usually performed with nonabsorbable synthetic suture material. In an infected wound suture material may have a negative effect on the healing of vascular anastomoses, leading to leakage and formation of false aneurysms. In a canine model 40 neck wounds and 40 groin wounds were contaminated with a standard suspension of Staphylococcus aureus.

Partial in vivo response to corticosteroid treatment in common variable immune deficiency.

The case of a 13-year-old girl with CVI is presented who required steroid treatment for myositis. After three weeks of treatment, the serum IgM level increased about ten-fold. Specific antibodies to vaccination antigens, which despite adequate vaccination were absent prior to any kind of treatment, could be synthesized following steroid treatment.

[Therapy and prevention of infectious endocarditis].

Only 40 years ago infectious endocarditis (IE) was lethal in most cases. Due to the development of numerous antibiotics and continuous improvements in heart valve surgery, a wide range of possibilities for therapy and prophylaxis of IE are available. The prognosis depends essentially on rapid and relevant diagnosis, which should be followed by immediate and adequate therapy consisting of general measures for treatment of septicaemic disease and specific antibiotic therapy.

Bacteriological assistance for optimal antibiotic therapy of endocarditis.

The specific anatomical changes of the infected valvular tissue demand the best bactericidal antibiotic therapy of endocarditis. However, quantitative antibiotic sensitivity testing and determination of the bactericidal effectiveness is not sufficiently routinely practised. It is presented how appropriate bacteriological assistance to achieve the optimum antibiotic therapy for endocarditis leads to favourable clinical results.

Prosthetic valve endocarditis: clinical findings and management.

Prosthetic valve endocarditis (PVE) was shown in 46 patients out of a group of 2163 carrying prosthetic heart valves. The cumulative rate of early PVE was 1.4% and 1.

Cell-substrate interaction. A method for evaluating the possible correlation between metastatic phenotype and cell surface energy.

The interfacial energy of the non-attached to substrate cell surface was analysed in tumor cell variants of the K-1735 melanoma and UV-2237 fibrosarcoma series, which exhibit distinct metastatic phenotypes. The highly metastatic cell variants exhibited a two-fold increase in the ability to form rapid cell substrate interactions, as compared with their low-metastatic counterparts. These results further highlight the possible role of cell adhesiveness in the process of metastasis.

The benefits of drug monitoring in patients with bacterial meningitis, eg, chloramphenicol monitoring.

Regular drug monitoring during therapy with chloramphenicol sodium succinate is actually recommended by expert centers. In this report a case of meningitis due to Salmonella typhimurium is described, which underlines the necessity of examining both the chloramphenicol and the chloramphenicol succinate concentrations. It is suggested that medical microbiologists and clinicians should be encouraged to take advantage of new, quick, and sensitive methods for drug monitoring in order to achieve optimal therapy.

[Diagnosis and current antibiotic therapy of urinary tract infections (author's transl)].

The problems caused by urinary tract infections confront the urologist with multiple specific tasks and call for cooperation with other specialists. In addition to basic and urological diagnostic acts recommendations are made for succeeding in diagnosis by means of bacteriology and nephrology. Considering the clinical degrees of urinary tract infections and the associated spectrum of causative bacterial agents the principles of current antibiotic treatment are presented
