Efficacy and onset of action of fluticasone propionate aqueous nasal spray on nasal symptoms, eosinophil count, and mediator release after nasal allergen challenge in patients with seasonal allergic rhinitis.

We studied the effect and onset of action of fluticasone propionate aqueous nasal spray (FPANS) on mediator release and eosinophil accumulation in nasal secretions and on nasal symptoms of patients with seasonal allergic rhinitis after nasal allergen challenge (NAC). At the end of the pollen season, 28 patients were randomized in a double-blind and crossover design to receive 7 days' treatment with FPANS (200 microg, once daily) and matching placebo. NACs were performed before and at 6 h and 1, 2, 3, and 7 days during treatment with FPANS or placebo. Nasal secretions were collected for a quantitative determination of mediators and eosinophil count before and 5 min after each challenge. Nasal symptoms were assessed by scales grading the severity of symptoms at the same time. Results showed that for mediator concentrations there was a significant decrease of leukotriene C4 (P<0.001) at 7 days after the first administration of FPANS as compared to placebo. Two days after FPANS, both eosinophil counts and eosinophil cationic protein (ECP) concentrations were lower than those of placebo (eosinophils: P=0.032; ECP: P=0.038). The onset became even more important at day 7 (eosinophils: P=0.001; ECP: P=0.009) during the FPANS treatment period. For the subjective nasal symptoms, a significant reduction of symptom scores for nasal obstruction occurred also at day 3 (P=0.017) and for sneezing at day 7 (P=0.003). There was not yet any significant improvement of the objective nasal airway resistance after the different NACs during the study period. In conclusion, this study demonstrated that topical fluticasone propionate is effective in the treatment of mucosal inflammation induced by NAC. For optimal control of nasal symptoms induced by repeated maximal allergen challenges, a treatment period of more than 1 week is required.

Pregnancy after electroejaculation in combination with intracytoplasmic sperm injection in a patient with idiopathic anejaculation.

OBJECTIVE: To assess the possibility of achieving a pregnancy in the wife of a patient suffering from idiopathic anejaculation who failed to respond to therapeutical modalities such as psychotherapy, sex therapy, and vibrostimulation. DESIGN: Case report. SETTING: The IVF program at the Leuven University Fertility Centre. PATIENT(S): A patient suffering from idiopathic anejaculation. INTERVENTION(S): Intracytoplasmic sperm injection (ICSI) in combination with electroejaculation. MEAN OUTCOME MEASURE(S): Fertility rate, cleavage rate, clinical pregnancy. RESULT(S): Two IVF procedures were performed of which the second resulted in an ongoing pregnancy and the delivery of a healthy boy. CONCLUSION(S): Electroejaculation may offer fertility chances in a patient suffering from idiopathic anejaculation resistant to conventional treatment modalities. When sperm quality shows very low motility, ICSI should be offered to improve pregnancy chances.

Very late return of spermatogenesis after chlorambucil therapy: case reports.

Two men were treated for a nephrotic syndrome with high-dose chlorambucil therapy; 6.5 and 14 years later, respectively, both were azoospermic with high plasmatic FSH values. Both patients showed active spermatogenesis, 15 and 19 years after the end of the treatment. This suggests that a return of spermatogenesis can occur even after very high cumulative doses of chlorambucil (between 3,000 and 6,500 mg) and after a very long time.

High ejaculate volume: a distinct entity?

In this study clinical, andrological and endocrinological data of a group of 101 patients with ejaculate volume of at least 8.0 ml are compared with data of 100 consecutive patients attending our infertility clinic. Within both groups correlations between different parameters are observed. Between both groups a significant difference in total sperm output is noted suggesting a 'dilution oligozoospermia' in the high ejaculate volume group. We suggest that, in order to avoid a falsely unfavourable fertility prognosis for those patients, total sperm output should be considered rather than sperm density. From the point of view of nomenclature, the term 'relative oligozoospermia' seems justified in cases with very high ejaculate volumes.

Male reproductive potential after MOPP therapy for Hodgkin's disease: a long-term survey.

The testicular function of 47 men who had been treated by MOPP chemotherapy for a Hodgkin's disease was studied in a long-term survey. Azoospermia was constant during at least 14 months after completion of the treatment. After a follow-up period of 89.4 +/- 54.7 months, 26 men were still azoospermic. No correlation could be found between the therapeutic regimen and the results of semen analysis. For the same treatment, some men recovered spermatogenesis within 5 years, others after more than 10 years while some were still azoospermic after 20 years. However, the association of infra-diaphragmatic irradiation to high dose MOPP therapy had a profound detrimental effect on spermatogenesis: only 3/13 men recovered. Sperm recovery was often incomplete: 17/21 men had a sperm count below 20 million ml-1. Yet, spontaneous pregnancies were obtained with severe oligozoospermia: only 1/11 sperm counts performed close to fertilization exceeded 20 million ml-1, and 8 were below 5 millions ml-1. FSH failed to be either a sensitive or a specific marker of sperm recovery, a discrepancy between FSH level and spermiogram being noticed in 18.2% of cases.

A retrospective evaluation of pipamperone (Dipiperon) in the treatment of behavioural deviations in severely mentally handicapped.

Nineteen severely mentally handicapped female patients (15-24 years), whose IQ was between less than 30 to 36, were treated with pipamperone (Dipiperon) because of behavioral disturbances. The dose varied from 40 to 180 mg/day spread over one to three intakes. The duration of treatment ranged between two and ten months. The therapeutic effect was evaluated by means of a 12-item rating-scale. A statistically significant improvement was obtained for nine of the 12 items. Overall improvement was very good in two, good in ten, moderate in five, and insufficient in two patients. Serious side-effects were not observed.
