Abstract
4545 Background: The combination of docetaxel, cisplatin, and fluorouracil (DCF) is clearly superior to CF in the treatment of patients (pts) with advanced gastric cancer (AGC). DCF is, however, associated with significant toxicity, including neutropenia, febrile neutropenia, diarrhea and mucositis. This study evaluated a biweekly, oxaliplatin-based modification of DCF. Methods: Pts with measurable, locally advanced or metastatic adenocarcinoma of the stomach or GE-junction and no prior chemotherapy received mFOLFOX (oxaliplatin 85 mg/sqm, leucovorin 200 mg/sqm, and fluorouracil 2.6 g/sqm via 24hr infusion) in combination with docetaxel 50 mg/sqm on day 1 every 2 weeks (FLOT-regimen). Prophylactic G-CSF was not administered. Overall response rate (RR) was the primary endpoint (power 80% to detect a RR of >40%) and toxicity profile the main secondary endpoint. The study was externally monitored according to GCP and data were reviewed by an independent safety board. Results: 59 pts (male, 41; female, 18) were enrolled. At the time of analysis, 53 pts were evaluable for toxicity and 51 pts for response. Median age was 60 (range, 29–76), median ECOG PS was 1, and almost all (93%) pts had metastatic disease. Of 51 pts, 2 had a CR and 25 pts attained a PR, adding to an overall RR of 53% (ITT-analysis). Stable disease was observed in 12 (23.5%) and progressive disease in 6 (11.8%) pts. Six (11.8%) pts were not evaluable for response. NCI-CTC grade 3 or 4 hematologic toxicity included leukopenia in 12 (22.6%), neutropenia in 23 (43%), and anemia in 2 (3.8%) pts. Febrile neutropenia was observed in 1 (1.9%) pt only. Other grade 3 or 4 toxicities included peripheral neuropathy in 4 (7.5%), nausea in 3 (5.7%), vomiting in 2 (3.8%) as well as diarrhea and fatigue in 5 (9.4%) pts each. No treatment related deaths were observed. Conclusions: FLOT is active and has a favorable toxicity profile in the treatment of pts with AGC. It may show activity also in perioperative treatment settings and may be considered as a useful treatment option for elderly pts. Survival data will be presented at the meeting. [Table: see text]

Abstract
LBA4016 Background: Cisplatin-based chemotherapy is a standard option in advanced gastric cancer. However, treatment results have been unsatisfactory so far, with a time to progression (TTP) of 3 to 4 months and an overall survival (OS) of 6 to 9 months. In addition, treatment regimens are too intense and toxicity is considerable. The aim of this 2-arm randomized trial was to determine whether FLO prolongs TTP and reduces toxicity as compared to FLP. Methods: Patients (pts) were randomized to receive FLO: F 2600 mg/m2 24 h infusion, L 200 mg/m2, and oxaliplatin 85 mg/m2, every two weeks or FLP: F 2000 mg/m2 24 h infusion, L 200 mg/m2, weekly, and cisplatin 50 mg/m2, every two weeks. The primary end point was TTP. Main secondary endpoints included toxicity, time to treatment failure (TTF), and OS. Based on a planned sample size of 218 pts, the trial was designed to have an 80% power to detect an improvement in median TTP from 3.5 to 5.0 months (1-sided log-rank test; significance level 0.05). Results: 220 pts (FLO/FLP, 112/108) were randomized between Aug 2003 and Jan 2006. Median age was 64 yrs and median ECOG was 1. 162 pts (FLO, 80; FLP, 81) had disease progression and 25 pts (FLO, 18; FLP, 8) are still under treatment. Median TTP was 5.7 months for FLO and 3.8 months for FLP (log-rank p = 0.081, Wilcoxon p = 0.019). Median TTF was 5.3 months for FLO and 3.1 months for FLP (log-rank p = 0.028). Response to FLO (34%) was superior to FLP (27%), with 15% and 30% of pts having disease progression as best response to FLO and FLP, respectively (chi-square for trend p = 0.012). Median treatment duration was 4.3 months with FLO and 3 months with FLP. FLO was associated with significantly less NCI-CTC grade 1–4 leukopenia, nausea, alopecia, fatigue, and renal toxicity and FLP was associated with significantly less peripheral neuropathy (chi-square for trend p < 0.05). Severe adverse events related to treatment were less frequent with FLO (8.9%) as compared to FLP (18.6%; p = 0.046). Conclusions: FLO reduced toxicity and improved efficacy as compared to FLP. This leads us to consider FLO for future studies in combination with targeted drugs to further improve the outcome of pts with gastric cancer. No significant financial relationships to disclose.

Abstract
We report on a patient who suffered a large subcapsular and perirenal haematoma after extracorporeal shockwave lithotripsy. Despite surgical intervention the bleeding did not stop for 6 days and 10 units of packed red blood cells were transfused. With the treatment of recombinant, activated factor VIII (NovoSeven((R))) an immediate haemostasis could be reached, so that impending nephrectomy could be avoided. This is the first case where FVIIa has been successfully used to stop a trauma-related bleeding in a patient without any obvious accompanying coagulation disorder.

Abstract
Despite almost forty years of widespread use, the mode of action of antidepressant drugs is still largely unknown. There is agreement that these drugs interact with central neurotransmission. Common findings are acute inhibitory actions on reuptake mechanisms for norepinephrine (NE) and for serotonin (5-HT) at presynaptic axons and chronic adaptive effects on neurotransmitter receptors on postsynaptic membranes. In particular, beta-adrenoceptor downregulation has been observed after chronic treatment with most antidepressants in vivo and in cell culture systems. We studied the effectiveness of Ze 117 (St. John's wort) extract (Hypericum perforatum) on NE- and 5-HT-uptake into rat brain slices. Potency and efficacy of the Ze 117 extract were compared with those of tricyclic (TCA) and selective serotonin reuptake inhibitor (SSRI)-type antidepressants. A dose-dependent inhibition was seen on NE and 5-HT uptake into brain slices. The Ze 117 extract was more selective for the uptake of NE than for that of 5-HT. The maximal extent of uptake inhibition by Ze 117 extract was comparable to that of imipramine (IMI), desipramine (DMI) or fluvoxamine for 5-HT, but lower for NE transport, than that of the synthetic antidepressants. Chronic exposure (8 days) of confluent C6-cell cultures to Ze 117 extract resulted in a dose-dependent beta-adrenoceptor downregulation equal to that induced by DMI, a potent TCA. None of these effects could be achieved with either hypericin or hyperforin alone in a relevant dose range. Our results indicate that the St. John's wort extract Ze 117 contains active, but as yet unknown antidepressant principles with effects comparable to those of TCAs.

Abstract
This study tests whether lead deposited to soil from automobiles during past years in a medium-sized US city (population 150,000) may present a current health risk. It examines the relationship between current soil lead concentrations at nine locations within the city of Springfield, Missouri, and airborne lead levels measured at the same locations during years (1975-1981) when lead emissions from automobiles were much greater than at present. A strong, significant correlation is found between soil and airborne lead levels at eight of the sites (r = 0.91, P < 0.005 for soil lead vs. 1979 airborne lead), in low-traffic areas as well as in areas adjacent to heavy traffic flow. Residual lead concentrations in these soils are relatively low, even for the high-traffic sites, as expected for a medium sized city.

Abstract
In asymptomatic infertility patients, no significant relationship was found between the presence of antisperm antibodies (ASA) in serum and in semen samples (IgG and/or IgA ASA), differentiated with the mixed antiglobulin reaction (MAR), and the microbial colonization of ejaculates covering a broad spectrum of microorganisms. Likewise, there was no significant association of ASA with microbial findings in patients' female partners, who also presented without symptoms of genital tract infection and were screened at the same time. Furthermore, ASA in semen (IgG and IgA) were not significantly related to several potential markers of subclinical male sexual gland infection or inflammation (leukocytes, PMN elastase, albumin, C3c) evaluated in aliquots of the same ejaculates used for immunological testing.

Abstract
To screen for infection with Chlamydia trachomatis in semen samples from asymptomatic men in couples consulting for infertility and to determine the relationship of seminal chlamydial antibodies with clinically relevant parameters of male fertility, 197 randomly chosen patients were enrolled in a prospective study. The median duration of infertility was 4 years (range 1-18). Screening for C. trachomatis and chlamydial antibodies of the immunoglobulin (Ig) A and IgG classes were performed in ejaculates and, in parallel, endocervical material from the partners of the patients and serum samples from both partners were evaluated. A comprehensive examination of semen quality included sperm analyses, semen cultures, local antisperm antibody (ASA) testing, the determination of potential infection markers, and sperm-cervical mucus interaction testing in vitro (SCMPT) and in vivo (post-coital testing). Chlamydial IgA antibodies were found in the semen samples of 18.8% (37/197) of the patients, while chlamydial IgG antibodies were found in 8.1% (16/197) of the patients. Screening for C. trachomatis was negative in all semen and cervical specimens. Only 5.5% of men remembered a past genital infection. Chlamydia antibodies (IgA/Ig/G) in semen were significantly correlated with chlamydia IgG antibodies in serum samples (P < 0.001). No marked relationship was found between the presence of seminal chlamydial antibodies and the major parameters of sperm analysis, semen cultures, local ASA and sperm penetration testing as an indicator of functional capacity. Seminal chlamydial antibodies were not significantly associated with potential infection or inflammation markers in aliquots of the same ejaculates. However, a significant relationship of chlamydial antibodies in patients' semen with past genital infections of their female partners was found with clinical relevance for a tubal infertility factor. The results indicate that in asymptomatic patients the presence of chlamydial antibody IgA or IgG in semen is not associated with reduced semen quality, potential seminal infection markers or impaired functional capacity as important determinants of male fertility; however, seminal chlamydial antibodies suggesting a previous sexually transmitted disease are significantly related to a tubal infertility factor of female partners.

Abstract
OBJECTIVE To determine the relationship of subclinical infection or inflammation of the male genital tract, as evaluated with seminal markers, with local antisperm antibodies as potential parameter of immunoresponse. PATIENTS One hundred ninety-one randomly chosen males of subfertile couples who were asymptomatic in terms of genital tract infection. SETTING Outpatient Infertility Clinic of the University of Heidelberg, Germany. MAIN OUTCOME MEASURES Determination of leukocytes rates in semen using an immunocytochemical method for differentiation of round cells and measurement of polymorphonuclear (PMN) granulocyte elastase concentration in seminal plasma in addition to semen cultures as screening for subclinical infection of the male genital tract. Determination of local antisperm antibodies (Ab) with the mixed antiglobulin reaction ([MAR] immunoglobulin [Ig] G and IgA) in aliquots of the same ejaculates. RESULTS Leukocyte rates of the round cells ranged from 0% to 93%, leukocytospermia was found in 6.8%. This was not related significantly to the presence of local antisperm antibodies of the IgG or IgA class. There was also no significant association of antisperm Ab with the concentration of PMN granulocyte elastase in seminal plasma and the outcome of semen cultures. CONCLUSIONS The results of this prospective study suggest that when the rate or number of leukocytes or the concentration of PMN elastase in semen are taken as markers for subclinical infection or inflammation of the male genital tract, this is not associated significantly with the production of local antisperm Ab of the IgG or IgA class as indicator of immunoreaction.

Abstract
Recruitment and retention of professionals is a major issue in rural health care. Following a literature review and series of focus groups, a questionnaire to ascertain why professionals applied for, stayed in and would consider leaving rural mental health work was constructed. The questionnaire also included questions regarding possible initiatives that could be undertaken to improve recruitments. The questionnaire was distributed through informal networks to over 900 professionals. Four hundred and seventy eight questionnaires were returned, representing a 52% return rate. According to the response work related issues were generally more important than lifestyle/personal issues particularly as reasons for applying for rural work. Lack of organisational support and professional isolation were important detractors of rural work, with strong support being expressed for initiatives that would address these issues. The findings suggest that recruitment action might highlight the scope, variety, challenge and autonomy aspects of work, with retention focusing on professional support and contact and increased organisational support.

Abstract
OBJECTIVE To determine the clinical significance of albumin determination in ejaculates by means of an easy office test to screen semen samples for subclinical infection-inflammation. PATIENTS One hundred fifty-nine randomly chosen males of couples with longstanding infertility (median duration of infertility 4 years (range 1 to 19 years) without clinical signs or symptoms of genital tract infection. SETTING Outpatient Infertility Clinic of the University of Heidelberg, Germany. MAIN OUTCOME MEASURES Screening of ejaculates for subclinical infection-inflammation by means of a ready-to-use kit for semiquantitative detection of albumin in addition to determination of leukocytes rates by means of monoclonal antibodies for differentiation of round cells and measurement of granulocyte elastase concentration in semen samples. Evaluation of sperm quality by means of standard sperm analysis including determination of local antisperm antibodies with the mixed antiglobulin reaction, evaluation of sperm functional capacity in vitro with the standardized sperm-cervical mucus (CM) penetration test, and semen cultures. All tests were performed from aliquots of the same ejaculates. RESULTS Screening of semen samples for elevated albumin with the modified paper strips proved to be very easy, quick, and suitable for routine use. Positive results were not related markedly to medical history and outcome of clinical examination as well as to standard parameters of sperm analysis and were not influenced by local antisperm antibodies of the immunoglobulin (Ig)G and/or IgA class and microbial colonization. However, albumin-positive semen samples were significantly less frequent in case of very good outcome of the sperm-CM penetration test. A significant relationship was found with high rates of leukocytes of the round cells in semen samples (total range 0% to 96%) and the concentration of granulocyte elastase (total range 1 to 880 micrograms/L). CONCLUSIONS The results of this prospective study suggest that the determination of albumin in semen samples with ready-to-use test kits might be a valuable additional marker for subclinical infection-inflammation of the male genital tract and therefore suitable for screening during infertility investigation.

Abstract
The incidence of postoperative myocardial infarction (MI) is proportional to the incidence of myocardial ischaemic episodes. Therefore, the prevention of such episodes is of great clinical importance. METHODS. In 90 patients undergoing coronary artery bypass grafting (CABG), perioperative i.v. treatment with either nitroglycerin (NTG), diltiazem (DIL), or the combination of DIL/NTG was used until arrival in the intensive care unit. Myocardial ischaemic episodes were monitored with an automatic ECG-ST-trend analyser (Marquette 7010). RESULTS. Significantly less ischaemic episodes were seen in the DIL group (6.7%) compared to the NTG group (13.2%) or DIL/NTG group (13.5%). Furthermore, significantly less ischaemic episodes were associated with relevant haemodynamic alterations in the DIL group (58.1%) compared to the NTG (89.1%) or DIL/NTG group (80.0%). Increases in heart rate were markedly reduced in the DIL group. DISCUSSION. DIL results in marked haemodynamic stabilisation during CABG, especially in the period immediately after extra-corporeal circulation. This might serve as an explanation for the significant reduction in ischaemic episodes in the DIL group compared to the other two groups. Therefore, perioperative prevention of myocardial ischaemia with the calcium antagonist DIL seems to be favourable in patients during CABG.

Abstract
STUDY OBJECTIVE To determine whether midazolam possesses a clinically significant antianalgesic action in surgical patients. DESIGN Randomized, controlled study. SETTING Inpatient anesthesia at a university department of neurosurgery. PATIENTS 2 groups of 10 patients each who were scheduled for supratentorial brain surgery, did not have elevated intracranial pressure, and were free from systemic disease. INTERVENTIONS Patients underwent anesthesia induction with hexobarbital, succinylcholine, and pancuronium; anesthesia was maintained with injections of droperidol-fentanyl (Group 1) or with midazolam-fentanyl (Group 2) following a predetermined repetitive dosing schedule, such that fentanyl 0.1 mg was injected upon predominant increases in heart rate, whereas droperidol 2.5 mg or midazolam 2.5 mg was injected upon increases in blood pressure. MEASUREMENTS AND MAIN RESULTS Duration of anesthesia and invasiveness of surgery were similar in both groups. The amount of fentanyl required was 0.55 +/- 0.18 mg/hr (mean +/- SD) in Group 1 and 0.53 +/- 0.17 mg/hr in Group 2. Injections of droperidol 7.5 +/- 3.4 mg/hr (Group 1) and midazolam 5.9 +/- 2.3 mg/hr (Group 2) were administered intraoperatively. This redosing regimen was associated with uninterrupted hemodynamic stability, indicating comparable and adequate anesthetic depth. Plasma concentrations of metabolites and hormones indicative of humoral stress activation did not differ between groups. CONCLUSION Under these clinical conditions, the administration of midazolam, when compared with droperidol, was not associated with signs of any antagonistic or antianalgesic action toward fentanyl-mediated analgesia.

Abstract
To further investigate possible prolongation of the frequency-corrected QT interval (QTc interval) after administration of droperidol (DRO), we studied 40 surgical patients who were randomly assigned to one of three groups, receiving an intravenous (IV) injection of either 0.1 mg/kg (Group 1, n = 10), 0.175 mg/kg (Group 2, n = 10), or 0.25 mg/kg (Group 3, n = 20) of DRO at induction of anesthesia. The QTc interval, heart rate, and arterial pressure were registered before and 1, 2, 3, 4, 5, 7.5, and 10 min after the respective dose injection. Significant prolongations of the median QTc interval were found in patients from all groups, ranging from 37 ms (8.0%) in Group 1, to 44 ms (10.6%) in Group 2, to 59 ms (14.9%) in Group 3, when compared with control. The heart rate showed a significant increase in all groups. Mean arterial pressure (MAP) was slightly but significantly decreased in Groups 1 and 3. Prolongation of the QTc interval is a predictable and dose-dependent side effect after injection of high-dose DRO.
