To evaluate the predictors of acute radiation pneumonitis after conformal thoracic radiotherapy in the treatment of locally advanced non-small cell lung cancer.Forty-seven consecutive patients were treated with conformal thoracic irradiation for locally advanced non-small cell lung cancer and retrospectively analysed. The mean total dose of radiotherapy was 65 Gy with respiratory gating in 19 cases. Neoadjuvant and concomitant chemotherapy was performed in 33 patients (70%) and 41 patients (87%) respectively.Eleven patients (23%) had an acute radiation pneumonitis, resulting in death for one patient. In univariate analysis, age, sex, pretherapeutic value of forced expiratory volume, non-gated radiotherapy and type of concomitant chemotherapy did not appear as contributing factors in contrast to the administration of neoadjuvant gemcitabine (P=0.03). The occurrence of acute radiation pneumonitis was significantly associated with non-tumour lung volumes irradiated to 13 Gy (V13, P=0.04), 20 Gy (V20, P=0.02) and 25 Gy (V25, P=0.006), the mean lung dose (P=0.008) and lung normal tissue complication probability (P=0.004). In multivariate logistic regression analysis, the occurrence of acute radiation pneumonitis was significantly associated with age above 75 years (odds ratio [OR]=16.72 ; P=0.02) and with administration of neoadjuvant gemcitabine (OR=18.08, P=0.04).Acute radiation pneumonitis is a common acute side effect of the conformal thoracic radiotherapy of locally advanced non-small cell lung cancer, requiring close post-treatment follow-up, particularly for elderly patients. The use of gemcitabine before radiation should be avoided. The benefits and risks of conformal thoracic radiotherapy must be carefully analyzed in view of the dosimetric parameters obtained.

Our goal was to develop quality of life questionnaires in French for women with pelvic organ prolapse.From two questionnaires previously developed for prolapse and validated in English, the Pelvic Floor Distress Inventory and the Pelvic Floor Impact Questionnaire, we have developed two questionnaires in French, the Inventaire des Symptômes de Prolapsus (ISP) and the Questionnaire sur l'Impact du Prolapsus (QIP). The ISP assesses symptom distress in women with pelvic floor disorders and measures how much these symptoms bother women. The QIP assesses life and emotional impact. These questionnaires were constructed after a double translation, a double expertise and patient interviews. A complete cross-validation into French is currently unfeasible due to cost considerations.The ISP and QIP questionnaires assess urinary, colorectal-anal and vaginal symptoms in relation to pelvic floor disorders. Both questionnaires significantly correlated with urinary and colorectal-anal symptoms. The main advantage of these instruments is the use of scales, with separate simple score for each scale.Based on two previously validated English questionnaires, the PFDI and the PFIQ, we have developed the first quality-of-life instruments in French for women with pelvic organ prolapse, the ISP and the QIP.

The relationships between testis size, hormone secretion and sperm production were studied during the spring (December) and autumn (May) in rams of two breeds with different breeding seasons and body weights (Corriedale and Australian Merino) maintained on native pastures and under natural photoperiods in Uruguay. Blood samples were collected at 20-min intervals during a 260-360-min period in 13 rams (four Corriedale, nine Australian Merino) during the late spring and autumn. Rams were weighed and testis size was estimated by orchimetry at each time period. Sperm production was estimated during a 2-week period, 2 months before blood collection and during each week following every blood collection. There was no relationship between testicular size and sperm production measured at the same time, nor between live weight and sperm production. In contrast, testicular volume during the late spring was correlated with sperm production in the autumn (r = 0.65; P = 0.02). The autumn serum LH was higher in Corriedale than in Merino rams. LH pulsatility was unaffected by season, but LH pulse frequency tended to be higher in Corriedale than in Merino rams, particularly in the late spring (2.37 versus 1.56 pulses/6 h; P = 0.08). Serum testosterone concentration was similar in both breeds and seasons. FSH levels were higher in the late spring than in the autumn in both breeds (Corriedale: 2.83 +/- 0.48 versus 2.17 +/- 0.24 ng x mL(-1); Merino: 2.23 +/- 0.24 versus 1.88 +/- 0.17 ng x mL(-1)). FSH and testosterone concentrations during the late spring were positively correlated with autumn sperm production (P = 0.07 and P = 0.03, respectively). In conclusion, the present experiment suggests that LH secretion is not a good parameter for the prediction of sperm production. In contrast, in our conditions (breeds and native pastures) testicular size and testosterone or FSH concentrations from the late spring may be used to predict sperm production in the autumn.
