Andrology: Transrectal electroejaculation in combination with in-vitro fertilization: an effective treatment of anejaculatory infertility after testicular cancer

Treatment of non-seminomatous testicular cancer often leadsto infertility due to anejaculation/retrograde ejaculation andpoor sperm quality. In these men spermatozoa may be obtainedby transrectal electroejaculation (TE), but the optimal strategyfor assisted procreation in these couples is not known. Ouraim was to examine whether TE and conventional in-vitro fertilization(IVF) would be successful. A total of 10 couples, with long-standinginfertility due to anejaculation or retrograde ejaculation aftertreatment for testicular cancer 5–14 years earlier, werereferred to our unit. All men underwent diagnostic TE undergeneral anaesthesia. Spermatozoa were recovered in nine cases.The antegrade fraction was prepared and used for IVF. Spermquality was variable and conventional IVF was considered impossiblein three cases. Altogether six IVF treatment cycles in six couplesresulted in five pregnancies, of which four resulted in a deliveryand one resulted in a spontaneous abortion. One additional pregnancyis ongoing after transfer of cryopreserved embryos. The fertilizationrate was 54% (33/61) and the cleavage rate was 97% (32/33).No complications relating to the procedure have been encountered.     

B-type natriuretic peptide and echocardiographic determination of ejection fraction in the diagnosis of congestive heart failure in patients with acute dyspnea

BACKGROUND: Echocardiography and B-type natriuretic peptide (BNP) are diagnostic tests for congestive heart failure (CHF), but an emergency diagnosis can be difficult. OBJECTIVE: To assess the diagnostic performance of BNP testing and echocardiographic assessment of left ventricular systolic function, separately and combined, for the identification of CHF in patients with acute dyspnea. DESIGN: Prospective, multinational, multicenter study. SETTING: Patients presenting to emergency departments in seven hospitals between June 1999 and December 2000. PATIENTS: A total of 1,586 patients with acute dyspnea. MAIN OUTCOME MEASURES: Echocardiographic determination of ejection fraction (EF) and point-of care BNP measurement for the diagnosis of CHF. RESULTS: Seven hundred nine of the 1,586 patients underwent echocardiography; 492 patients (69.4%) had a final diagnosis of CHF. Patients with CHF were older (68.5 years vs 61.6 years, p < 0.0001), had a lower EF (39.5% vs 56.1%, p < 0.0001), and a higher BNP (683 pg/mL vs 129 pg/mL, p < 0.0001) than patients without CHF. Area under the receiver operating characteristic (ROC) curve for the diagnosis of CHF was significantly higher for BNP (0.89) than for EF (0.78; area under the ROC curve difference, 0.12; p < 0.0001). The sensitivity of BNP > or = 100 pg/mL for the diagnosis of CHF was 89%, and specificity was 73%. Values for EF < or = 50% had a sensitivity of 70% and a specificity of 77%. Multivariate logistic regression analysis showed that, in combination with clinical, ECG, and chest radiograph data, BNP > or = 100 pg/mL and EF < or = 50% remained independent predictors of CHF (odds ratios, 32.1 and 6.2, respectively). The proportions of patients who were correctly classified were 67% for BNP alone, 55% for EF alone, 82% for the two variables together, and 97.3% when clinical, ECG, and chest radiograph data were added. CONCLUSION: BNP measurement was superior to two-dimensional echocardiographic determination of EF in identifying CHF, regardless of the threshold value. The two methods combined have marked additive diagnostic value.     

Influence of route of administration on progesterone metabolism

While inducing similar progesterone levels, the ratio of 5α- and 5β-pregnanolone/progesterone plasma concentrations has been dramatically increased after oral as opposed to vaginal administration, in a cross-over study. The known psychotropic effects of 5α- and 5β-pregnanolone lead to different indications and precautions for oral and vaginal administration of progesterone.     

Altered postural control during the luteal phase in women with premenstrual symptoms

The purpose of this study was to investigate postural control in women with and without premenstrual symptoms (PMS) in three hormonally verified phases of the menstrual cycle. Thirty-two women were recruited to participate in the study and 25 of these women were included in the results. Menstrual cycle phases were determined by sex hormone analyses in serum and LH detection in urine. A prospective rating of PMS was used to divide the subjects into two groups: one with PMS (cyclic) and one without (non-cyclic). For measurement of postural control, subjects stood on a force platform (AMTI) in two-legged stance (eyes open and closed) and one-legged stance (eyes open and closed). There were no significant differences in the two-legged stance between the phases of the menstrual cycle or between groups. In one-legged stance with eyes open, there was a significant increase in postural displacement in the mid-luteal phase in the cyclic group, but no differences were detected between phases in the non-cyclic group. These findings may be related to the previously reported increased injury rate and psychomotor slowing in the luteal phase in women with PMS.     

Genetic linkage of autosomal dominant progressive supranuclear palsy to 1q31.1

Progressive supranuclear palsy (PSP) is a disorder of unknown pathogenesis. Familial clusters of PSP have been reported related to mutations of protein tau. We report the linkage of a large Spanish family with typical autosomal dominant PSP to a new locus in chromosome 1. Four members of this family had typical PSP, confirmed by neuropathology in one case. At least five ancestors had similar disease. Other members of the family have incomplete phenotypes. The power of the linkage analysis was increased by detecting presymptomatic individuals with 18F-fluoro-dopa and 18F-deoxyglucose positron emission tomography. We screened the human genome with 340 polymorphic markers and we enriched the areas of interest with additional markers. The disease status was defined according to the clinical and positron emission tomography data. We excluded linkage to the tau gene in chromosome 17. PSP was linked, in this family, to one area of 3.4 cM in chromosome 1q31.1, with a maximal multipoint < OD score of +3.53. This area contains at least three genes, whose relevance in PSP is unknown. We expect to further define the gene responsible for PSP, which could help to understand the pathogenesis of this disease and to design effective treatment.     

Expressions of hope in cystic fibrosis patients: a comparison with the general population

PURPOSE: Hope was evaluated in Norwegian patients with cystic fibrosis (CF). PARTICIPANTS: The subjects were 87 Norwegian adults with CF and a control group of 1020 from the general population (GP). METHODS: Subjects completed a questionnaires that included the Herth Hope Index and demographic variables. Data on health-related variables were collected for the CF group. RESULTS: The mean age of the CF patients was 29 years (range 18-54). Almost 50% had a forced expiratory volume for one second percent predicted (FEV1%) below 50%, and 21% reported perceiving being in a bad phase of the disease. The CF patients reported lower (poorer) levels of hope than the GP sample, especially for the item scared about the future. However, they scored higher on inner strength and were younger, more often living alone, unmarried, not in paid work, but with similar educational levels. Levels of hope increased with increasing age in the CF patients but decreased for the GP subjects. The health variable that most affected hope in the CF sample was pulmonary function, not the presence of asthma or chronic lung infections. CONCLUSIONS: Persons growing up with CF experience many challenges. CF patients expressed slightly lower levels of hope and were more scared of the future. They scored higher on inner strength than the general population.     

An outbreak of <Emphasis Type="Italic">Salmonella</Emphasis> Enteritidis phage type 34a infection associated with a Chinese restaurant in Suffolk,United Kingdom

Background

On 30^th July 2002, the Suffolk Communicable Disease Control Team received notifications of gastrointestinal illness due to Salmonella Enteritidis in subjects who had eaten food from a Chinese restaurant on 27^th July. An Outbreak Control Team was formed resulting in extensive epidemiological, microbiological and environmental investigations.

Methods

Attempts were made to contact everybody who ate food from the restaurant on 27^th July and a standard case definition was adopted. Using a pre-designed proforma information was gathered from both sick and well subjects. Food specific attack rates were calculated and two-tailed Fisher's exact test was used to test the difference between type of food consumed and the health status. Using a retrospective cohort design univariate Relative Risks and 95% Confidence Intervals were calculated for specific food items.

Results

Data was gathered on 52 people of whom 38 developed gastrointestinal symptoms; 16 male and 22 female. The mean age was 27 years. The mean incubation period was 30 hours with a range of 6 to 90 hours. Food attack rates were significantly higher for egg, special and chicken fried rice. Relative risk and the Confidence interval for these food items were 1.97 (1.11–3.48), 1.56 (1.23–1.97) and 1.48 (1.20–1.83) respectively. Interviews with the chef revealed that many eggs were used in the preparation of egg-fried rice, which was left at room temperature for seven hours and was used in the preparation of the other two rice dishes. Of the 31 submitted stool specimens 28 tested positive for S Enteritidis phage type 34a and one for S Enteritidis phage type 4.

Conclusion

In the absence of left over food available for microbiological examination, epidemiological investigation strongly suggested the eggs used in the preparation of the egg-fried rice as the vehicle for this outbreak. This investigation highlights the importance of safe practices in cooking and handling of eggs in restaurants.

     

Robot-assisted radical cystoprostatectomy in a small child with rhabdomyosarcoma: a case report

We report the first case of a robot-assisted radical cystoprostatectomy in a 22-month-old boy with embryonal rhabdomyosarcoma in his urinary bladder. Treatment according to international protocol CWS-2002 P (Cooperative Weichteilsarkom Studie) was given prior to surgery. The da Vinci S Surgical System from Intuitive Surgical (Sunnyvale, CA, USA) was used to laparoscopically remove the urinary bladder and prostate radically. The surgical procedure performed and the postoperative course were uneventful. This technique is safe and feasible also in small children. It seems to have advantages over open surgery and no disadvantages. We recommend this technique for further use.
