    Notes: In a French region where farmer's lung (FL) is common, we determined the prevalence of FL precipitins in dairy farmers and analyzed the relation between the presence of FL precipitins and the clinical probability of the disease. All the exposed dairy farmers of both sexes (n= 2555) from five districts of the Doubs department were asked to respond to a medical and professional questionnaire. A total of 1763 (69%) farmers agreed to participate. Precipitins tests were conducted in 551 (31%) farmers who showed any respiratory symptom and in a random sample of 100 asymptomatic farmers. Serum for each farmer was analyzed by both double diffusion and immunoelectrophoresis against Micropolyspora faeni (MF) and extracts of moldy hay (HE) from Doubs. The 651 farmers were then divided into four groups (G 1–4) with a decreasing probability of FL (G1: typical FL symptoms; G4: asymptomatic farmers). The estimated prevalence of precipitins in the whole population was as follows: 1) by double diffusion, against HE: 83%, against MF: 27%; 2) by immunoelectrophoresis, against HE: 26%, against MF: 19%. There was a close “linear” relation between the prevalence of precipitins detected by immunoelectrophoresis against HE and the symptoms: 51% in G1, 36% in G2, 29% in G3, and 13% in G4. Precipitins detected by immunoelectrophoresis were also related to exposure and geography (more immunization in tableland area than in plain or mountain area). Presence of precipitins detected by double diffusion was not related to symptoms, exposure, or geography. This study shows that the prevalence of precipitins is high in the exposed dairy farmers of Doubs, and suggests that immunoelectrophoresis (with the antigens used) is a more effective method for the diagnosis of FL than double diffusion.

    Notes: Abstract Background: Cisplatin is one of the most effective cytotoxic drugs used in the treatment of certain neoplasms, but is also one which most frequently induces nausea and vomiting. Combination of corticosteroids with ondansetron enables greater control of emesis than that obtained with ondansetron alone, but some patients still experience symptoms. The objective of this randomised, double-blind, multicentre, parallel group study was to examine the benefit of the addition of metopimazine (MPZ), a dopamine receptor antagonist, to the combination of ondansetron + methylprednisolone (O + M) in the prevention of cisplatin-induced nausea and vomiting in patients uncontrolled [i.e., at least one emetic episode (vomiting and/or retching) or moderate or severe nausea] during their previous course of cisplatin based chemotherapy, despite antiemetic treatment with a combination of a 5-hydroxytryptamine3 receptor antagonist (5HT3) with a corticosteroid. The impact of the treatment on the patients' quality of life was also evaluated using two specific questionnaires: the FLIC (Functional Living Index for Cancer), and the FLIE (Functional Living Index for Emesis). Patients and methods: The intent-to-treat population consisted of 338 patients; 168 patients received the triple combination of ondansetron, methylprednisolone and metopimazine (O + M + MPZ), and 170 patients received ondansetron plus methylprednisolone (O + M). Tumour type was comparable in the two treatment groups, the most prevalent being lung cancer. Patients in group O + M + MPZ received ondansetron as an 8 mg intravenous injection prior to chemotherapy on day 1 followed by 8 mg tablets b.i.d. from D2 to D3, methylprednisolone as a 120 mg intravenous injection prior to chemotherapy on D1 and followed by 16 mg tablets b.i.d. from D2 to D3, and metopimazine as a 40 mg intravenous injection prior to chemotherapy on D1 and followed by 15 mg capsules b.i.d. on D2 to D3. Patients in group O + M received treatment with ondansetron and methylprednisolone as above. Results: Analysis of the primary efficacy criterion (absence of emetic episode throughout the course of chemotherapy) revealed a success rate of 53% in the group receiving O + M + MPZ and 38% in the group receiving O + M (P = 0.008). Analysis of the secondary efficacy criteria (nausea grade, number of emetic episodes and global patient satisfaction on D1 and from D2 to D3) showed a statistically significant difference between the two groups, in favour of the O + M + MPZ treatment. The scores obtained with the FLIC and FLIE questionnaires did not reveal any significant differences between the two groups. Treatment was well tolerated in both groups. Conclusion: The study showed that the addition of MPZ to the combination O + M was an effective and well tolerated antiemetic treatment, with a 15% increase in efficacy compared to the combination in patients not controlled during their previous course of chemotherapy. The addition of metopimazine to existing regimens containing 5HT3 receptor antagonist and steroid combination should be considered for patients who fail on their previous course.

    Notes: Abstract. Objective: To assess the lung cancer patient's prognosis in the intensive care unit with early predictive factors of death. Design: Retrospective study from July 1986 to February 1996. Setting: Medical intensive care unit at a university hospital. Patients: Fifty-seven patients with primary lung cancer admitted to our medical intensive care unit (MICU). Measurements and results: Data collection included demographic data (age, sex, underlying diseases, MICU admitting diagnosis) and evaluation of tumor (pathologic subtypes, metastases, lung cancer staging, treatment options). Three indexes were calculated for each patient: Karnofsky performance status, Simplified Acute Physiology Score (SAPS) II, and multisystem organ failure score (ODIN score). Mortality was high in the MICU: 66% of patients died during their MICU stay, and hospital mortality reached 75%. In multivariate analysis, acute pulmonary disease and Karnofsky performance status 〈70 were associated with a poor MICU and post-MICU prognosis. For the survivors, long-term survival after MICU discharge depended exclusively on the severity of the lung cancer. Conclusions: We confirmed the high mortality rate of lung cancer patients admitted to the MICU. Two predictive factors of death in MICU were identified: performance status 〈70 and acute pulmonary disease.

    Notes: Abstract Background: The aim of this study was to analyze SCLC patients beyond 30 months, particularly their outcome, their way of life, and factors which could influence relapses, second-primary cancers and death. Patients and methods: Between January 1986 and May 1995, 263 SCLC patients who survived longer than 30 months were included from 52 French institutions. The analysis was performed on the 155 cases confirmed by a pathologic review. Results: Physical, mental and psychological states were considered as normal at 30 months in respectively 70.3%, 87.7% and 67.7% of patients, not influenced by prophylactic cranial irradiation, number of chemotherapy cycles, CCNU or cisplatin. Therapeutic sequelae were neurological impairment (13%), pulmonary fibrosis (18%) and cardiac disorders (11%) at 30 months. Return to work was possible for 40% of patients in the first two years following diagnosis. Among 43 relapsing patients, 33 benefited from a second-line treatment. Their median survival was 12 months since retreatment, and seven patients have survived again longer than 30 months. Age 〉60 at the time of diagnosis was found as an independent factor increasing the risk of relapse beyond 30 months (OR = 2.46, IC 95% (1.16–5.26), P = 0.01). The risk of relapse became less than 10% beyond five years. Twenty patients (13%) developed a second primary cancer in a mean time of 58.6 months. The risk of second primary cancer was increased by a number of chemotherapy cycles 〉6 (OR = 3.25, IC 95% [1.08-9.8] P = 0.02) and by an age 〉60 (OR = 2.92, IC 95% (1.07–7.97), P = 0.03). Five- and 10-year survival rates were respectively 68% and 44%. In these patients having reached a 30-month survival, three independent factors were predictive of a survival longer than five years: age ≤60 at the time of diagnosis (OR = 2.85, IC 95% (1.23–6.6), P = 0.01), chest radiotherapy (OR = 3.1, IC 95% (1.28–7.69), P = 0.006) and absence of relapse (OR = 4.5, IC 95% (1.75–12.5), P = 0.002). This study suggests that: 1) therapeutic sequelae are rather mild, allowing return to work in 40% of patients; 2) relapsing 30-month survivors can benefit from second-line treatment; 3) SCLC cure can be achieved with a 10-year follow-up.
