Thus buy 1 mg decadron acne extractor tool, in front of the international audience he proclaimed: „Like the vital force in earlier times buy 0.5mg decadron free shipping acne before period, so today the mysterious forces of the vital cell play a paralyzing role in our theories of immunity”. At the congress in London, Metschnikoff defended his theory in a comment from the foor, arguing that the „army of phagocytic cells is really a salutary force formed in the struggle for the existence of the animal organism”. Mendelsohn has argued that because they inhabited different cultural worlds of experience, Koch, Pasteur and their respective disciples developed profound differences in their understanding of microorganisms and disease – with Koch’s school regarding bacteria as the specifc, unidirectional, determinant cause of disease, while the Pasteurians stressed an interactive and ecological model of disease: they saw disease as evidence of a „struggle for life” (that is for oxygen and nutrients) between microbes and cells infuenced by variable milieu factors – an account that was obviously developed by Pasteur without reference to the Darwinian concept of „struggle“. In looking closer at this time period, I will enhance the complex picture of the „two cultures of bacteriology” by showing how differences between the two research schools were reconfgured through a reciprocal demarcation of scientifc concepts in the direct and indirect exchanges between Behring and Roux/Metschnikoff. And while I’m going to demonstrate how, on both sides of the border, the peculiarities contributed to divergent steps in the experimental development of the diphtheria serum (with its various dead ends as well as its consolidating processes), it will also become clear that the private exchanges between researchers in Berlin and Paris in the early 1890s were nevertheless respectful and open minded enough to allow for a mutual adoption of experimental practices. To characterize these exchanges at this time as „cooperation”15 would be, in my opinion, off the mark given the ostentatious demarcations that the protagonists engaged in. It suggests that the „gaps“ and „lacunae“ in the (documented) research process – compared to the German situation – might in part be due to a divergence in the style of reasoning and experimenting at the Pasteur Institute. A closer analysis of the French serum research remains a desideratum and although the German side of the story has been told more than once,17 there are features missing that are of key importance for the rapid transformation of the erratic experimental extraction of the serum into a stable production process. The paper will proceed as follows: frst, I outline the practical implications of the different research cultures for the early experiments on diphtheria immunization around 1890. Those experiments addressed the issue of „weakening” or „attenuating” the infective agent. Second, I will reconstruct the experimental phase in the development of an effective immunization technique that enhanced the therapeutic value of the diphtheria serum and enabled large scale serum production simultaneously in Berlin and Paris in 1894. Here, I’m going to assess how different concepts of immunity were simultaneously specifed in a tense interplay between Behring, Roux and Metschnikoff that did not inhibit the mutual adoption of experimental practices. In the third and fnal part of this article, I will show how divergent concepts of immunity led to differences in the use of methods for evaluating the „effcacy“ of the therapeutic serum. This argument is based on his examination of the development of a serotherapy for diphtheria and tetanus. While his argument seems to hold true for Roux’s scientifc activities in the long run, it oversimplifes the development of diphtheria serum therapy, because the exchanges between Berlin and Paris were marked by considerable tension and ‘dissociation’. The beginning of immunization research was marked by an experimental exploration of methods designed to reduce the pathogenic effect of the diphtheria bacteria or their purifed toxin, so that test animals could recover and thereby acquire immunity. Behring’s approach involved looking for chemical means to achieve this goal, which he – like other German researchers – described as „Abschwächung“ (weakening). Behring had worked intensively on this subject in the eighteen eighties, turning himself into an expert on the question of disinfectants, a subject of much importance in military medicine. As Jonathan Simon has argued, this practical achievement in working with antiseptics served as the basis for Behring’s initial approach to the therapy of infectious diseases. That approach involved a kind of „inner disinfection“ using antagonistic substances to render microbes innocuous within a living body. Nevertheless, a direct trial of iodine trichloride on infected children failed because of the chemical’s unacceptably caustic effects. In contrast to Behring’s progress, Roux and Yersin attempted to manipulate the pathogenic power of diphtheria cultures or the fltered toxin using heat, antiseptic chemicals, and other methods in such a way that immunization would result. In an article from 1889, Roux and Yersin were still convinced it was promising to search for a „chemical attenuation“ that would allow the animals to recover from the infection and thus gain immunity (Roux and Yersin 1889, 282). As Mendelsohn has argued, this period of their work was marked by a return to Pasteurian research axioms, with the researchers trying to vary the „virulence“ of the diphtheria cultures – conceived as a kind of biological property – in order to fnd a stable attenuated microorganism that could be used to develop a method for „microbic vaccination“24. One approach was to try to simulate in in vitro cultures the clinical conditions of patients who had recovered spontaneously from diphtheria. They also searched for „naturally attenuated” cultures and interpreted pseudo-diphtheria-bacilli as such rather than as a separate species of bacteria (as was commonly believed at the time). In their publications they showed themselves increasingly interested in a biological „hereditary attenuation” of microbes that they distinguished from a chemical or mechanical deactivation or weakening that would not affect subsequent generations. But there were no indications in his lecture (or in other sources) that, in the meantime, he or his collaborators had been conducting systematic immunization experiments against diphtheria since Yersin had left for Indochina at the end of the summer of 1890. Immunization and Immunity Given Roux’s conceptual and practical distance from diphtheria immunization, the question arises: How did he return to diphtheria serum research? As opposed to a „chemical vaccination“ using toxins (Roux 1891, 518; Émile Roux and Alexandre Yersin, “Contribution à l’étude de la diphthérie. The difference between „microbic“ and „chemical vaccination“ probably refects, in a distorted way, Pasteur’s shift from a „biological“ theory of immunity, based on the nutritional exhaustion of the pathogenic organism, to a „chemical“ theory, that viewed a chemical „vaccinal substance“, produced by the living bacteria, as the immunising agent (Gerald L. Mendelsohn has pointed out that the difference between the schools of Koch and Pasteur was not the French admission of virulence variability versus a German rigid species concept of frm properties.

The expected number of cases of leukaemia was estimated from age- and sex-specific inci- dence rates derived from the Varese Cancer Registry in Italy buy 1mg decadron free shipping skin care 70. The cumulative dose of etoposide ranged between 100 and 30 000 mg/m2 (median discount 0.5 mg decadron overnight delivery skin care procter and gamble, 5200 mg/m2); 70 children received more than 4000 mg/m2. Five cases of acute promyelocytic leukaemia were diagnosed, all in etoposide-treated patients (four girls, one boy; latency, 27–106 months). No cases of acute promyelocytic leukaemia were observed in patients who had not received etoposide. Both studies lacked sufficient power to detect a signi- ficant difference in leukaemia risk between patients with Langerhans cell histiocytosis treated with and without etoposide, although no cases of acute myeloid leukaemia were observed without etoposide treatment. The Working Group also noted that a small, unspecified proportion of patients in the Italian cohort were treated with teni- poside (Haupt et al. The absence of an increased risk for acute myeloid leukaemia after this regimen has now been documented in several large studies of the risk for second malignancies (Pedersen-Bjergaard et al. Further evidence for the absence of cases of acute myeloid leukaemia with myelodysplastic syndrome in patients treated with this regimen comes from several trials with long-term follow-up (Ozols et al. Thirty-five patients, treated between 1979 and 1983, received cisplatin, vinblastine and bleomycin and, at relapse, bleomycin (15 mg/m2 weekly), etoposide (120 mg/m2 for five days) and cisplatin (20 mg/m2 for five days). In the subgroup of 20 patients who had received a cumulative etoposide dose of > 2000 mg/m2, two cases of acute myelomonocytic leukaemia occurred. For the 177 patients treated after 1983 to 1989 with first-line bleomycin, etoposide and cisplatin, the doses were adjusted according to risk category: 115 patients received standard doses (100 mg/m2 etopside for five days (cumulative dose, 2000 mg/m2), 20 mg/m2 cisplatin for five days, 15 mg/m2 bleomycin weekly). In 62 patients who received high- dose treatment consisting of etoposide (200 mg/m2 for five days; cumulative dose, 3000 mg/m2), cisplatin (40 mg/m2 for five days) and bleomycin (15 mg/m2 weekly), two cases of acute myeloblastic leukaemia (one in a patient with extragonal germ-cell tumour) and one case of myelodysplastic syndrome developed. The latencies after eto- poside treatment were 15 and 29 months for acute myeloblastic leukaemia and 68 months for the case of myelodysplastic syndrome. The expected number of de-novo cases of acute myeloid leukaemia was estimated from the leukaemia incidence reported in the Danish Cancer Registry for 1973–77. No leukaemias or dysplastic syndromes were observed among the 130 patients who had received ≤ 2000 mg/m2 etoposide, whereas five cases were seen among the 82 patients who had received > 2000 mg/m2 (p = 0. Although five cases of leukaemia and dysplastic syndrome were found in the 212 etoposide-treated patients, none was found in a previous cohort of 127 patients with germ-cell tumour treated with vinblastine and similar doses of cisplatin and bleomycin (p = 0. Bokemeyer and Schmoll (1993) assessed the risk for secondary neoplasms after therapy for germ-cell tumours in 1025 patients treated between 1970 and 1990 in Germany. Patients followed-up for longer than 12 months were eligible (1018 patients; 394 had seminomatous germ-cell tumours). The median follow-up was 61 months, and the median age of the patients at diagnosis was 28. The chemotherapy regimens consisted mainly of cisplatin, bleomycin and either vinblastine or etoposide. A total of 293 patients received etoposide during their treatment: 221 patients received cumu- lative doses of ≤ 2000 mg/m2; 72 patients received > 2000 mg/m2. The cumulative incidence of second tumours after etoposide-containing therapy was 1. Among the 221 patients who received ≤ 2000 mg/m2 etoposide, three developed a secondary tumour: one carcinoid tumour, one rhabdomyosarcoma and one lymphoblastic leukaemia; the last patient had received four cycles of bleomycin, etoposide and cisplatin (cumulative dose of etoposide, 2000 mg/m2), and the interval to second leukaemia was 16 months. The study was limited to those who had achieved complete remission or a stable partial response with no tumour markers after chemotherapy, with a minimum follow-up of 12 months. The first cohort consisted of 22 patients who were treated between 1983 and 1989 with three or four cycles of bleomycin, etoposide and cisplatin as induction chemotherapy followed by cisplatin, etoposide and ifosfamide as salvage chemotherapy at relapse. The second cohort was composed of 50 patients with metastatic testi- cular cancer who had been treated during 1984–88 with first-line chemotherapy consisting of a ‘double-dose’ of cisplatin, a ‘double-dose’ of etoposide and bleomycin (175 mg/m2 cisplatin and 1000 mg/m2 etoposide per cycle; four cycles). The third cohort consisted of 41 patients who had been treated in a stepwise dose–escalation protocol with the cisplatin, etoposide and ifosfamide regimen as first-line therapy for ‘advanced’ germ- cell tumours. The patients were treated during 1989–92 with 150 mg/m2 cisplatin and 8000 mg/m2 ifosfamide plus either 750 mg/m2 or 1000 g/m2 etoposide per cycle for four consecutive cycles. The fourth cohort consisted of 15 patients treated between 1990 and 1993 for relapsed testicular cancer with high doses of carboplatin, etoposide and ifos- famide followed by autologous stem-cell rescue.

An adult is a person older than 19 years of age unless national law defnes a person as being an adult at an earlier age. A child is a person 19 years or younger unless national law defnes a person to be an adult at an earlier age. However, in these guidelines when a person falls into the 10 to 19 age category they are referred to as an adolescent (see adolescent defnition). These guidelines defne key populations to include both vulnerable and most-at-risk populations. These guidelines defne most-at-risk populations as men who have sex with men, transgender people, people who inject drugs and sex workers. Each country should defne the specifc populations that are particularly vulnerable and key to their epidemic and response based on the epidemiological and social context. A couple refers to two people in an ongoing sexual relationship; each of these is referred to as a partner in the relationship. How individuals defne their relationships varies considerably according to cultural and social context. A public health approach involves a collaborative effort by all parts of the health sector, working to ensure the well-being of society through comprehensive prevention, treatment, care and support. The term is often used interchangeably with “needing treatment”, although this implies an immediate risk or an obligation to initiate treatment.
