This paper presents a hierarchical grading method applied to Jonagold apples. Several images covering the whole surface of the fruits were acquired thanks to a prototype grading machine. These images were then segmented and the features of the defects were extracted. During a learning procedure, the objects were classified into clusters by k-mean clustering. The classification probabilities of the objects were summarised and on this basis the fruits were graded using quadratic discriminant analysis. The fruits were correctly graded with a rate of 73 %. The errors were found having origins in the segmentation of the defects or for a particular wound, in a confusion with the calyx end. [less ▲]

Weaning is a critical period for piglets. Promoting solid food ingestion in the farrowing pen and early after weaning is essential to optimise piglets' performance, health and welfare. A lot of papers report studies about pigs' perception of the feed's organoleptic properties. Pigs are attracted by specific flavors and show taste acuity for the five basic stimuli. The choice of pigs for a diet formulation is mainly based on the protein content of the food and the absence of toxin or anti-nutritional contaminants. They also tend to prefer eating pellets and crumbles rather than meal. Weaned pigs readily accept liquid feed. Wet/dry feeders give the possibility to the pigs to mix water and food at the same place and notably allow them to eat faster when they are fed meal. However, wet feeding may induce greater food wastage. The influence of food visual aspect on feed intake in pigs has been little assessed. Visual and auditory stimuli produced by the feeding behaviour of penmates have although a better-known impact on feed intake in this species. [less ▲]

HIV infection rages at the endemic state in Sub Saharan African and especially in Congo Brazzaville. We report the observation of three female patients infected with HIV and developing multiple myeloma. The three patients were treated at the University hospital of Brazzaville between 2000 and 2002. In two cases multiple myeloma was discovered after the diagnosis of HIV infection. In the other case, the diagnosis of HIV infection was posterior to the occurrence of multiple myeloma. HIV infection was symptomatic in two cases who received consequently antiviral treatment. Multiple myeloma was diagnosed at an advanced stage in the three cases. The paraprotein was an IgG in two cases and an IgA in the other one. The CD4 counts before treatment were around 200/mm3 in two cases and within normal limits in the third case. Viral load was not measured. VMCP and VAMCP regimens were administered without major complications and under anti-infectious prophylaxis. The follow-up is still insufficient to assess the medium-term evolution and to determine the prognosis of multiple myeloma. The description of these three cases confirms the involvement of HIV in B cell lymphoma genesis. [less ▲]

The seriousness of varicella-zoster virus (VZV) infection as a public health issue is becoming clearer as country-specific epidemiologic and pharmacoeconomic data become available. In Germany, for example, studies have shown that >5.5% of immunologically healthy individuals develop varicella-related complications such as bacterial superinfections, acute neurologic disorders, pneumonia, bronchitis and otitis media; whereas in Italy, 3.5 to 5% of childhood cases of varicella cause complications such as upper respiratory tract and cutaneous infections. Varicella vaccines are now available. These live attenuated Oka strain vaccines have been shown in extensive studies to be highly immunogenic and well-tolerated in immunocompetent and immunocompromised children, with seroconversion rates ranging from 94 to 100% and 53 to 100%, respectively. These vaccines are also highly effective against clinical disease. These considerations led to a reevaluation of varicella vaccination policies. A routine varicella vaccination program targeting healthy children has already been implemented in the US, and data produced are encouraging and valuable. Similar strategies have not yet been adopted across Europe. The European Working Group on Varicella (EuroVar) was formed in 1998 to address the issues surrounding varicella epidemiology in Europe. After a series of meetings, the EuroVar members prepared a consensus statement recommending routine varicella vaccination for all healthy children between 12 and 18 months and to all susceptible children before their 13th birthday, in addition to catch-up vaccination in older children and adults who have no reliable history of varicella and who are at high risk of transmission and exposure. However, such a policy is recommended only if a very high coverage rate can be achieved. This could be reached with a measles-mumps-rabella-varicella combined vaccine. [less ▲]

According to the recent recommendations of the European Community and the World Health Organization, identification of risk factors for fracture or low bone mineral density (BMD) should help health professionals to make a better use of bone densitometry. This includes helping patients to modify their behaviour and act on modifiable risk factors (correction of low calcium intake and vitamin D deficiencies, etc.) and also to provide evidence-based guidance for starting a treatment when necessary. In this context, we previously developed a clinical scoring index, OSIRIS (OSteoporosis Index of RISk), for classifying women into three categories of risk of osteoporosis. In order to evaluate the discriminatory performance of OSIRIS, we performed the present prospective study in a sample of 889 postmenopausal women from France. The osteoporosis risk depends on the OSIRIS category. Thus, 62% of women in the 'high-risk' category (OSIRIS < or = -3) were osteoporotic, compared to 34% of women in the 'intermediate-risk' category (OSIRIS ranged between -3 and +1) and only 16.8% of women in the 'low-risk' category (score OSIRIS > 1). These results might contribute to the development of more efficient screening strategies for osteoporosis. The patients in the low-risk category do not require immediate BMD testing; women with 'intermediate risk' have to be carefully followed by their doctor with BMD testing decided on a case-by-case basis; for those within the high-risk category, treatment may be initiated immediately and BMD testing performed either to assess the efficacy of the treatment or to increase the long-term compliance of the patient. In conclusion, for clinical practice, a user-friendly tool has been developed. This tool, called OSIRIS, as far as a simple rule allows, identifies the level of osteoporosis risk in women. [less ▲]

Hypothesis / aims of study The aim of this study was to prospectively evaluate the efficacy of the TVT-O inside-out procedure for the treatment of female stress urinary incontinence (SUI). Study design, materials and methods From March 2003 through September 2003, 53 patients with clinical evidence of SUI participated in this prospective clinical trial. Preoperative evaluation included complete history, physical examination, multichannel urodynamics, urine analysis, and cystoscopy. None of the patients presented the following exclusion criteria: post-void residual volume (PVR) ≥ 100 cc, detrusor overactivity or acontractility, contraindication to anesthesia, pregnancy, neurological pathology, or active urinary or vaginal infection. All patients met the following inclusion criteria: age > 25 and < 85 years, clinically demonstrated SUI, positive Ulmsten test, and maximum cystometric capacity ≥ 300 mL. In all patients, a sub-urethral tape (Gynecare®) was inserted by one single surgeon via an inside-out transobturator approach (TVT-O), as previously described (1). Evaluation of SUI, urgency/urge incontinence, daytime urinary frequency/nocturia, and lower urinary tract symptoms (LUTS) suggestive of bladder outlet obstruction/retention was carried out using the Measurement of Urinary Handicap scale questionnaire (2). The importance of urinary incontinence was assessed with a visual analog scale graded from 0 to 10. Quality of life (QoL) assessment was performed using the validated Ditrovie self-administered questionnaire. Outpatient follow-up was perfomed at 1 and 6 months, and every 6 months thereafter. Follow-up evaluation included physical examination with a stress test, uroflowmetry, PVR, and symptom, visual analog, and QoL scales scoring. Cure was defined as no leakage based on both symptom scale scoring and physical examination. Improvement was defined as at least a 50% decrease in symptoms based on the questionnaire’s evaluation. Chart review was conducted by a physician not associated with the surgical procedure. The specific protocol used in this study was approved by the Medical Ethics committee of our Institution. All patients had given their written informed consent. Methods, defintions,and units conform to the standards recommended by the ICS. Results Mean age of the patients was 61.2 years (36 to 80). Of the 53 patients, 20 had undergone previous pelvic surgery. Forty-eight patients suffered from SUI. Five patients did not complain of SUI but had clinical evidence of SUI after reduction of pelvic organ prolapse (POP) during vaginal examination. The TVT-O procedure was associated with POP cure (performed before TVT-O) in 12 patients. Maximal urethral closure pressure was < 30 cm H20 in 6 patients. Follow-up time was ≥ 6 months in all women (max = 12.5; mean = 8). A total of 33 and 20 women received spinal and general anesthesia, respectively. Intraoperative blood loss was < 100 cc in all cases. No vaginal wall, urethral, or bladder perforation was encountered. No hematoma, neurological complication, fistula, vaginal or urethral erosion, or tape rejection was observed. Some patients reported pain symptoms, directly after the procedure, mainly located in the thigh regions (either uni- or bilaterally). Pain was always mild, never requiring opioid antalgics. No patient complained of persistent pain; indeed, pain had completely vanished within the first post-operative month in all cases. At the latest follow-up visit, PVR was < 100 cc and max flow rate was ≥ 10 mL/sec in 49 (92.4%) and 39 (73.6%) patients, respectively. One patient underwent an immediate tape release procedure for complete retention 2 days after TVT-O. Thereafter, the patient had no PVR and was completely dry. The tape was sectioned in 2 patients for chronic retention and/or urgency associated with bladder outlet obstruction, 4 and 7 months after the operation. Based on the SUI questionnaire evaluation and physical examination, 50 (94.3%) patients were cured. SUI symptoms had improved in 1 patient and had not changed in another. One patient with POP not complaining of SUI preoperatively (but with clinically demonstrated SUI following POP reduction) developed SUI after POP cure associated with TVT-O. Analysis of the urgency questionnaire’s results revealed that among the 53 patients, 32 did not complain of any urgency before the operation. Of these 32 patients, 3 patients developed de novo urgency, with one of them requiring tape sectioning because of obstruction-associated urge incontinence. Among the 21 patients with preoperative urge symptoms, 15 of them reported disappearance of urgency after the procedure. Urge symptoms were unchanged in the remaining 6 patients. Daytime frequency/nocturia symptoms scale scoring showed that 4 patients had a worsening of these symptoms while all other patients were either improved or unchanged. LUTS suggestive of bladder outlet obstruction/retention appeared or worsened in 3 patients, amongst which the 2 patients who required tape sectioning. These symptoms were unchanged or decreased (mainly in patients with associated POP cure) in all other patients. Analysis of the urinary incontinence visual analog and QoL scale scores demonstrated that the majority of patients reported disappearance of urinary leakage together with significant improvement of their QoL (Figures 1 and 2). Interpretation of results As already suggested by the results of a recent feasibility study (1), TVT-O appears to be associated with a minimal risk of peri-operative complications. Indeed, in our present prospective study, no injury to the bladder, vagina, or urethra was encountered and we have not observed any vascular, digestive or neurological complication. Our data suggest that TVT-O is associated with high objective and subjective SUI cure rates and a low incidence of post-operative complications. Longer follow-up times are required to determine the long-term efficacy of TVT-O. Concluding message The short term results of this prospective study suggest that TVT-O is a safe and efficient surgical procedure for the treatment of female SUI. References 1.
