Abstract
Background Pulmonary metastasis (M1-PUL) as first site of dissemination in pancreatic ductal adenocarcinoma (PDAC) is a rare event and may define a distinct biological subgroup. Patients and methods Arbeitsgemeinschaft Internistische Onkologie-Young Medical Oncologists-Pankreas-0515 study (AIO-YMO-PAK-0515) was a retrospective German multicenter study investigating clinical and molecular characteristics of M1-PUL PDAC patients; 115 M1-PUL PDAC patients from 7 participating centers were included. Clinical characteristics and potential prognostic factors were defined within the M1-PUL cohort. Archival tumor samples were analyzed for Her2/neu, HNF1A and KRT81 expression. Additionally, messenger RNA (mRNA) expression analysis (using a 770-gene immune profiling panel) was carried out in the M1-PUL and in a control cohort (M1-ANY). Results Median overall survival in the entire M1-PUL cohort was 20 months; the most favorable prognosis (median survival: 28 months) was observed in the subgroup of 66 PDAC patients with metachronous lung metastases after previous curative-intent surgery. The number of metastatic lesions, uni- or bilateral lung involvement as well as metastasectomy were identified as potential prognostic factors. Her2/neu expression and PDAC subtyping (by HNF1A and KRT81) did not differ between the M1-PUL and the M1-ANY cohort. mRNA expression analysis revealed significant differentially expressed genes between both cohorts: CD63 and LAMP1 were among the top 20 differentially expressed genes and were identified as potential mediators of organotropism and favorable survival outcome of M1-PUL patients. Conclusion M1-PUL represents a clinically favorable cohort in PDAC patients. Site of relapse might already be predetermined at the time of surgery and could potentially be predicted by gene expression profiling. The retrospective multicenter AIO-YMO-PAK-0515 study defines M1-PUL as a clinically favorable subgroup in PDAC. The number of metastatic lesions, bilateral lung involvement and surgical metastasectomy may serve as prognostic factors. Immune-related gene expression differs between patients with isolated pulmonary relapse versus other sites of relapse.

Abstract
The purpose of this study was to characterize CI-992 pharmacokinetics and pharmacokinetics/pharmacodynamics (PK/PD) in sodium deplete monkeys. Panels of monkeys were administered CI-992 as a 1 h intravenous infusions (0.1 and 1 mg kg-1) or as single oral doses (0, 10, 50, and 100 mg kg-1). Mean arterial blood pressure (MABP) was monitored and serial blood samples were collected up to 24 h postdose. Plasma CI-992 concentrations were quantitated by radioimmunoassay. Pharmacokinetic parameters were calculated by noncompartmental methods. PK/PD relationships were assessed by standard methods. Oral bioavailability of CI-992 in the monkeys was < 2%; steady-state volume of distribution was 0.67 L kg-1; clearance was 10.4 mL min-1 kg-1. Following oral administration, tmax generally occurred 6-9 h postadministration; plasma CI-992 concentrations increased with increasing dose between 10 and 50 mg kg-1, but did not change appreciably from 50 to 100 mg kg-1. After intravenous administration, change in MABP was correlated with plasma CI-992 concentration through an effect compartment model in which the maximum achievable effect was a 22 mm Hg decrease in MABP; the steady-state concentration which produced half the maximum effect was 11 ng mL-1. Following the 10 mg kg-1 oral dose the maximum decrease in MABP was 19.1 mm Hg; higher doses did not produce greater maximum response but increased the duration of action. In contrast to observations following intravenous administration, a trend for decreasing MABP with increasing plasma CI-992 was not apparent following oral CI-992 administration.

Abstract
Human brucellosis, a multisystem disease which may mimic other conditions, has a low incidence in childhood and the diagnosis may easily be missed. Over a 7-month period 9 children with brucellosis presented to the Department of Paediatrics and Child Health, Tygerberg Hospital. Six of the children had consumed unpasteurized milk. The main presenting symptoms were fever, fatigue, headache, myalgia and haematuria. Clinical signs included lymphadenopathy (3), nasopharyngitis (2), features of lower respiratory tract infection (2), splenomegaly (2) and pyrexia (1). The diagnosis was made on the basis of a positive serological titre (> 1:160) for Brucella abortus. The prozone phenomenon was encountered in 6 cases; however, the Coombs test confirmed the diagnosis in these cases. Children under 7 years were treated with co-trimoxazole and rifampicin and those over 7 years with tetracycline and rifampicin, for at least 6 weeks. No relapses were detected on follow-up.
