RESUMO

The grey maize weevil, Tanymecus dilaticollis, is a polyphagous species, which is among the most important pests of maize in Southeastern Europe. The efficacy of commercial products with two species of entomopathogenic nematodes (EPNs), Steinernema carpocapsae and Heterorhabditis bacteriophora, was investigated against adults of the grey maize weevil under laboratory conditions. Nemastar®, containing S. carpocapsae was more effective on T. dilaticollis adults than Nematop® containing H. bacteriophora, when applied uniformly to the surface of the soil, on Petri dishes containing T. dilaticollis adults. Results showed that S. carpocapsae rates of 83-333 infective juveniles/adult caused > 94% mortality in T. dilaticollis adults, whereas H. bacteriophora caused 27-61%, adult mortality, after exposure of insects to the commercial products of EPNs for 15 days. The infection rates of EPNs increased with concentration applied and ranged from 70-83% and 19-64% for Nemastar® and Nematop®, respectively. Subsequent field and semi-field tests were conducted with Nemastar® (application rate of 50 million S. carpocapsae per 100 m2) in maize crops with biological (mycoinsecticide Naturalis®, biofungicides and fertilizers) and chemical seed treatment (Gaucho® FS 600; active ingredient: imidacloprid) in Knezha, Bulgaria. Nematodes were found only in the dead specimens, in open plots and cages sprayed with the commercial nematode product. Nematode sprayings contributed for higher maize yields in the open maize plots in the fields with different seed treatments. We suggest that the use of powder formulation of S. carpocapsae in combination with biologically treated maize seeds can contribute to minimize the use of chemical insecticides against the grey maize weevil. The results obtained can be used as a base to further tests to ascertain the efficacy of EPNs products before they can be recommended for use in the integrated approach to T. dilaticollis management.

RESUMO

BACKGROUND: In order to prevent risks associated with insufficient family care, it is mandatory to provide early childhood interventions for parents unable to cope with their young children in best time. Children̛s hospitals represent one pillar that hasn´t been fully explored yet. METHODS: As a proof-of-concept, we performed a study to determine the feasibility of a standardized risk assessment tool during routine work of doctors and nurses in a university department. RESULTS: Our data indicate that a standardized screen to assess stress is powerful in identifying stressed parents, especially those with children under the age of one year. In this context, psychosocial stress in families with newborns was most frequently indicated. The placement rates into early childhood interventions (8.5%) and youth welfare services (11.3%) correspond to the literature. DISCUSSION AND CONCLUSION: The standardized risk assessment tool can be used as a "call button" and delivers a basis for further differentiated exploration of the families by a specialized team and might be used to deliver services for these families. In summary children's hospitals might be useful to provide a low-threshold access into early childhood interventions.

RESUMO

PURPOSE: Psychosexual development is currently underrepresented in hypospadias outcome research. The aim of this study was to develop and validate a questionnaire addressing psychosexual long-term satisfaction, specifically of adolescent patients, after hypospadias repair. MATERIALS AND METHODS: In a multistep participative design we identified key interests of adolescent patients with hypospadias. Next, a questionnaire addressing specifically the psychosexual satisfaction of adolescents after hypospadias repair was established. A population of 109 former patients with hypospadias was then assessed using this questionnaire. Furthermore, functional and cosmetic aspects, behavioural anomalies, and sexual activity were investigated. Age-matched patients undergoing circumcision served as control patients. Possible influence factors on patient satisfaction were investigated. Clinical trial registry site: German Registry of Clinical Trials DRKS, Freiburg, Germany (Reference: DRKS00003432). RESULTS: Key interests of adolescent patients were "normal appearance of the penis", "normal function of the penis regarding voiding and sexual activity", "no limitations regarding cosmetic appearance to others", "no limitations to sexual activity", and an "unimpaired masculine identity". The "Satisfaction In Genital Hypospadias Treatment" (SIGHT) questionnaire was developed using these items and using previously published evaluation systems. Nine questions address psychosexual aspects and two additional questions address current sexual activity. Internal consistency was high and retest reliability acceptable. The patient population showed a normal strength and difficulties score (SDQ). Overall satisfaction was high and similar to that of the control group. In a Spearman correlation a high SDQ value, erectile problems, and complications correlated negatively with satisfaction. CONCLUSION: To date, few studies have examined patients' satisfaction and psychosexuality. To our knowledge, the SIGHT questionnaire is the first to be developed participatively and in a stepwise fashion in collaboration with a paediatric psychologist and an open approach to determine items specifically important for adolescents. The SIGHT questionnaire can thus offer a relevant assessment of patients' psychosexual satisfaction. It is most suitable to supplement current strategies that so far mostly neglect the impact on psychosexual wellbeing.

RESUMO

The bleeding disorder Bernard-Soulier syndrome (BSS) is caused by mutations in the genes coding for the platelet glycoprotein GPIb/IX receptor. The septin SEPT5 is important for active membrane movement such as vesicle trafficking and exocytosis in non-dividing cells (i.e. platelets, neurons). We report on a four-year-old boy with a homozygous deletion comprising not only glycoprotein Ibß (GP1BB) but also the SEPT5 gene, located 5' to GP1BB. He presented with BSS, cortical dysplasia (polymicrogyria), developmental delay, and platelet secretion defect. The homozygous deletion of GP1BB and SEPT5, which had been identified by PCR analyses, was confirmed by Southern analyses and denaturing HPLC (DHPLC). The parents were heterozygous for this deletion. Absence of GPIbß and SEPT5 proteins in the patient's platelets was illustrated using transmission electron microscopy. Besides decreased GPIb/IX expression, flow cytometry analyses revealed impaired platelet granule secretion. Because the bleeding disorder was extremely severe, the boy received bone marrow transplantation (BMT) from a HLA-identical unrelated donor. After successful engraftment of BMT, he had no more bleeding episodes. Interestingly, also his mental development improved strikingly after BMT. This report describes for the first time a patient with SEPT5 deficiency presenting with cortical dysplasia (polymicrogyria), developmental delay, and platelet secretion defect.
