    Notes: The effect of lysostaphin on Staphylococcus aureus phagocytosed by monocytes was investigated. The results showed that lysostaphin adheres to monocytes by a temperature-independent mechanism, is not adequately removed from monocytes by washing, and penetrates by means of a temperature-dependent mechanism. In in vitro assays of monocyte function, phagocytosed S. aureus can be killed by lysostaphin after penetration of the cells during incubation or by adhering lysostaphin when the monocytes are disrupted.

    Notes: The usefulness of lysostaphin for the removal of cell-adherent and extracellular bacteria in assays performed to measure the intracellular killing of Straphylococcus aureus by granulocytes was investigated. The results showed that the adherence of lysosiaphin to the granulocyte surface is effectuated by a temperature-independent process and that bound lysostaphin is still microbicidal. Lysosiaphin also penetrates into the granulocytes by a temperature dependent process and kills ingested S. aureus intracellularly. Therefore, despite reports to the contrary in the literature, lysosiaphin is not a reliable agent for the removal of only extracellular S. aureus and should no longer be used in assays to determine the rate of intracellular killing by granulocytes.

    Notes: Abstract An in vitro transcription-translation assay was used to study the membrane topology of rat liver cytochrome P450 3A1. N-terminus deletion mutants were constructed to assess the importance of N-terminal regions in the stable incorporation of the protein into the microsomal membranes. Wild-type nascent cytochrome P450 bound to microsomes as an integral membrane protein through its hydrophobic N-terminal segments, uncleaved by signal peptidase. Deletion of the most N-terminal hydrophobic segment (positions 7–26) had a dramatic effect on endoplasmic reticulum membrane integration. Confirming the essential role of this stretch in P450 3A1 membrane targeting, proteolysis-resistant membrane-associated peptides were observed in all the in vitro translated mutants containing that segment. It is concluded that the membrane topogenesis of P450 3A1 is determined mainly by the amino-terminal hydrophobic segment.

    Notes: Summary In a controlled randomized study among 48 patients undergoing 75 courses of aggressive antileukemic therapy, it was shown that cotrimoxazole was less effective than penicillin G in preventing septicemia due to viridans streptococci. Both antibiotics were given intravenously. During 35 episodes of chemotherapy in the group of patients on penicillin G only, one patient developed a streptococcal bacteremia; this contrasted with bacteremia and septicemia in seven patients during 40 episodes in the group on cotrimoxazole. In three of these seven patients, septicemia was associated with respiratory failure and it was the cause of death in one. Both aerobic gram-negative rods and streptococci which caused infection despite cotrimoxazole prophylaxis were resistant to cotrimoxazole. Side effects such as hypersensitivity and favorable or unfavorable interaction with the oral selective decontamination regimen were similar for the two drugs, with the exception of colonization withCandida spp, which occurred more often in patients on cotrimoxazole than in patients on penicillin.

    Notes: Summary The phagocytosis and intracellular killing by granulocytes as well as the opsonizing capacity of the serum were studied in 13 patients who had undergone allogeneic bone marrow transplantation. Phagocytosis was normal in all patients. A moderately impaired opsonic activity of the serum was found in two patients, who were investigated within 30 days after the transplantation. The intracellular killing was less than control values in two patients. In one patient this was probably due to the existence of a split chimerism.

    Description / Table of Contents: Zusammenfassung Die Wirkung von Acyclovir intravenös (in einer Dosis von 30 mg/kg pro Tag für fünf Tage) auf den unkomplizierten Herpes zoster wurde bei 51 Patienten in einer Doppelblindstudie geprüft. Obwohl bei den vorhandenen Herpes zoster-Läsionen eine Tendenz zu rascherer Heilung bestand und das Neuauftreten von Läsionen in der Acyclovir-Gruppe etwas früher aufhörte, waren diese Unterschiede statistisch nicht signifikant. Unter der Behandlung war die Schmerz-Score bei Patienten, die Acyclovir erhielten, signifikant niedriger als bei Patienten, die Placebo erhielten. Bei der Verlaufsbeurteilung fanden sich zwischen den Gruppen jedoch keine Unterschiede. Zu Komplikationen des Herpes zoster kam es nur in der Plazebo-Gruppe (in je zwei Fällen Generalisation und Keratitis). Mit der möglichen Ausnahme des Zoster im Trigeminus-Bereich oder starker Schmerzen scheint Acyclovir bei immunkompetenten Patienten mit Herpes zoster nur von geringem Wert zu sein.
    Notes: Summary The effect of intravenous acyclovir (at a dosage of 30 mg/kg per day for five days) on uncomplicated herpes zoster was investigated in 51 patients in a double-blind study. Although existing herpes zoster lesions tended to heal more rapidly and new lesions ceased to appear somewhat earlier in the acyclovir group, these differences were not statistically significant. During treatment, patients on acyclovir had significantly lower pain scores than placebo-treated patients. At follow-up, however, there was no difference between the two groups. Complications of herpes zoster occurred only in the placebo groups (generalization in two and keratitis in two cases). With the possible exception of trigeminal zoster or severe pain, acyclovir seems to offer little benefit for immunocompetent patients with herpes zoster.

    Description / Table of Contents: Zusammenfassung Wir berichten über eine rezidivierendeListeria monocytogenes-Bakteriämie bei einer 46 Jahre alten Lebertransplantat-Empfängerin. Durch Serotypisierung wurde festgestellt, daß die beiden Bakteriämien durch verschiedene Stämme ausgelöst wurden. Die Möglichkeit einer wiederaufflackernden persistierenden Infektion wurde ausgeschlossen. Wir gehen davon aus, daß die rezidivierende Bakteriämie bei dieser prädisponierten Patientin durch Reinfektion verursacht wurde und daß die Antibiotikatherapie (Ampicillin plus Aminoglykosid) den Infektionserreger vollständig eliminiert hatte. Es bestand folglich keine Indikation für eine Antibiotika-Langzeit-Suppressionstherapie. Die Infektionsquelle für dieseL.-monocytogenes-Infektionen wurde nicht gefunden.
    Notes: Summary We report a case of a recurrentListeria monocytogenes bacteraemia in a 46 year-old liver transplant patient. Serotyping revealed that the two episodes of bacteraemia were caused by different strains. The possibility of a recrudescence of a persisting infection was rejected. We concluded that the recurrent bacteraemia in this predisposed patient was due to re-infection, and that antibiotic treatment (amoxicillin plus an aminoglycoside) resulted in a complete eradication of the infective microorganism. Therefore long-term suppressive antibiotic treatment was not indicated. The source of theseL. monocytogenes infections was not found.

    Notes: Abstract The use of ciprofloxacin for the treatment of pulmonary infection in cystic fibrosis patients was investigated. Therapy was successful in six patients and unsuccessful in three patients. In one patient therapy had to be stopped because serum transaminase levels showed a 5- to 8- fold increase. During therapy resistance developed inHaemophilus influenzae, Staphylococcus aureus andPseudomonas aeruginosa.

    Description / Table of Contents: Zusammenfassung Bei einer Patientin mit systemischem Lupus erythematodes wurde röntgenologisch eine Wirbelosteomyelitis diagnostiziert. In Material, das durch Punktur des dritten Lendenwirbelkörpers gewonnen wurde, ließ sich kulturell wiederholtCandida albicans nachweisen. Sechs Monate vorher war die Patientin mit Kortikosteroiden behandelt und parenteral ernährt worden. Zu dieser Zeit wurden aus dem Blut und von der Spitze des entfernten Subclavia-Katheters Hefen kultiviert. Nachdem eine Wirbelosteomyelitis durchCandida diagnostiziert worden war, wurde die Patientin sieben Monate lang mit Ketoconazol behandelt. Entsprechend den klinischen und röntgenologischen Befunden kam es zu einem eindrucksvollen Heilungsverlauf. Zwölf Monate nach Beendigung der Ketoconazolbehandlung — zum Zeitpunkt der Manuskripterstellung — waren bei der Patientin keine Zeichen für einen Rückfall festzustellen.
    Notes: Summary Candida vertebral osteomyelitis was diagnosed in a patient with systemic lupus erythematodes following X-ray evidence of osteomyelitis and the repeated culturing ofCandida albicans from material obtained by needle biopsies from the third lumbar vertebra. The patient had been on glucocorticosteroids and parenteral nutrition six months previously. At that time, a yeast was cultured from the blood and the tip of the subclavian catheter which had been removed. After candida vertebral osteomyelitis was diagnosed, she was treated with ketoconazole for seven months. Recovery was impressive, as judged by the clinical and radiographic findings. At the time of writing this paper — 12 months after the withdrawal of ketoconazole — the patient showed no signs of recurrence.
