Wishes or Constraints? Mothers' Labour Force Participation and its Motivation in Switzerland

The aim of this article is to estimate the impact of various factors related to role conflict theory and preference theory on the reduction of women's labour force participation after their transition to parenthood. Objective and subjective dimensions of women's labour force participation are assessed. The empirical test is based on a survey of couples with children in Switzerland. Results show that compared to structural factors associated with role conflict reduction, preferences have little impact on mothers' labour force participation, but explain a good deal of their frustration if the factual situation does not correspond to their wishes. Structural factors, such as occupation, economic resources, childcare, and an urban environment, support mothers' labour force participation, whereas active networks and a home centred lifestyle preference help them to cope with frustrations.

Failure of voriconazole to cure disseminated zygomycosis in an immunocompromised child.

Voriconazole is increasingly used as a first-line agent for empirical antifungal therapy of prolonged febrile neutropenia in paediatric cancer patients. We describe the case of a 9-year-old patient with stage IV Burkitt lymphoma, who developed pulmonary and splenic zygomycosis while receiving voriconazole for persistent febrile neutropenia. The causative agent, Absidia corymbifera, was identified by broad-range fungal PCR in a lung biopsy sample. The patient was successfully treated with a combination of partial resection of the left upper lobe and antifungal therapy with high-dose liposomal amphotericin B followed by oral itraconazole as demonstrated by resolving pulmonary infiltrates on serial high resolution CT scans. CONCLUSION: This case emphasises that the lack of in vitro activity of voriconazole against zygomycetes is clinically relevant. Failure of voriconazole in suspected fungal infection should be investigated for the possibility of zygomycosis. Broad-range polymerase chain reaction may be able to identify the causative organism when cultures remain sterile.

Molecular and social regulation of worker division of labour in fire ants.

Reproductive and worker division of labour (DOL) is a hallmark of social insect societies. Despite a long-standing interest in worker DOL, the molecular mechanisms regulating this process have only been investigated in detail in honey bees, and little is known about the regulatory mechanisms operating in other social insects. In the fire ant Solenopsis invicta, one of the most studied ant species, workers are permanently sterile and the tasks performed are modulated by the worker's internal state (age and size) and the outside environment (social environment), which potentially includes the effect of the queen presence through chemical communication via pheromones. However, the molecular mechanisms underpinning these processes are unknown. Using a whole-genome microarray platform, we characterized the molecular basis for worker DOL and we explored how a drastic change in the social environment (i.e. the sudden loss of the queen) affects global gene expression patterns of worker ants. We identified numerous genes differentially expressed between foraging and nonforaging workers in queenright colonies. With a few exceptions, these genes appear to be distinct from those involved in DOL in bees and wasps. Interestingly, after the queen was removed, foraging workers were no longer distinct from nonforaging workers at the transcriptomic level. Furthermore, few expression differences were detected between queenright and queenless workers when we did not consider the task performed. Thus, the social condition of the colony (queenless vs. queenright) appears to impact the molecular pathways underlying worker task performance, providing strong evidence for social regulation of DOL in S. invicta.

Fever of unknown origin in a Swiss-born child: don't miss tuberculosis!

Tuberculosis incidence is low in Switzer land. We report here on a Swiss-born toddler. Tuberculosis manifested with a fever of unknown origin, mimicking an inflammatory or autoimmune disorder triggering a high dose of corticosteroid treatment. The disease went unrecognized for several weeks until development of a miliary tuberculosis with advanced central nervous system involvement. This case highlights the difficulties encountered in diagnosing tuberculosis and in identifying the origin of this case. It reminds us that this disease must never be forgotten when facing a child with persistent fever who must be screened for, before starting immunosuppressive therapy.

Prematurity, maternal stress and mother-child interactions.

OBJECTIVE: Previous studies have shown that premature birth and the immaturity of the child can affect the quality of the parent-child relationship. The present study examines the relationship between maternal and infant interactional behavior over time and infant perinatal risk factors as well as maternal perinatal recollected traumatic experience. Few studies have explored the relationship between maternal stress and the quality of parent-infant interaction. DESIGN: Mother-child interaction was recorded at 6 and 18 months of infant's age, in a population of 47 preterm infants (GA<34 weeks) and 25 full-term infants, born in 1998, during a play interaction. According to the Care Index, sensitivity, control and unresponsiveness have been used to code maternal interactional characteristics, and cooperation, compliance-compulsiveness, difficulty and passivity have been used to code the infant's interactional characteristics. The level of maternal stress was evaluated with the Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ), and the infant's perinatal risk factors were assessed with the Perinatal Risk Inventory (PERI). RESULTS: Mothers of high-risk infants, as well as mothers that had experienced traumatic stress in the perinatal period, were less sensitive and more controlling at 6 months. The interactional behavior of the preterm infant was different from that of the full-term infant at 18 months of age, and was correlated with maternal traumatic stress but not with perinatal risk factors. CONCLUSION: These results underline the importance of maternal traumatic experience related to premature birth and its potential long lasting influence on mother-child interactional behavior.

Type I osteogenesis imperfecta and multiple osteochondromas in the same child.

A male infant showed a humeral diaphysis fracture at 5 months of age and a distal tibial physis fracture at 2 years of age. A specialized consultant ruled out child abuse. This child had the characteristic features of type I osteogenesis imperfecta: blue sclerae, osseous fragility, and presumably autosomal dominant inheritance, as his father suffered from similar disorders. Later on, multiple painful osteochondromas were also found and some of these were surgically treated. The child's mother showed several peripheral osteochondromas. We describe the follow-up of this patient up to the age of 18 years. To our knowledge, the fortuitous association of these two inherited conditions has not been reported in medical literature.

Cervical nerve root synovial sarcoma in a child with chromosomal (X;18) translocation. Case report and review of the literature.

We report on an 11-year-old female with a history of cervicobrachialgia and progressive weakness of the right arm. Cervical spine MRI showed an enhancing heterogeneous intradural mass occupying the right C6-C7 foramen. She underwent a right C6-C7 foraminotomy with a complete macroscopic removal of the lesion. Pathological examination revealed a synovial sarcoma. Treatment was completed by chemotherapy and proton radiotherapy, and the girl remained free of symptoms for 3 years. After appearance of new symptoms, a local recurrence was confirmed, and despite aggressive treatment with salvage chemotherapy and radiotherapy, the disease progressed beyond medical control, and the child died, 6 years after diagnosis. Early recognition of this rare entity compared to its more benign differential diagnosis is crucial, as an aggressive management is needed.

When is a child with status epilepticus likely to have Dravet syndrome?

PURPOSE: To identify clinical risk factors for Dravet syndrome (DS) in a population of children with status epilepticus (SE). MATERIAL AND METHODS: Children aged between 1 month and 16 years with at least one episode of SE were referred from 6 pediatric neurology centers in Switzerland. SE was defined as a clinical seizure lasting for more than 30min without recovery of normal consciousness. The diagnosis of DS was considered likely in previously healthy patients with seizures of multiple types starting before 1 year and developmental delay on follow-up. The presence of a SCN1A mutation was considered confirmatory for the diagnosis. Data such as gender, age at SE, SE clinical presentation and recurrence, additional seizure types and epilepsy diagnosis were collected. SCN1A analyses were performed in all patients, initially with High Resolution Melting Curve Analysis (HRMCA) and then by direct sequencing on selected samples with an abnormal HRMCA. Clinical and genetic findings were compared between children with DS and those with another diagnosis, and statistical methods were applied for significance analysis. RESULTS: 71 children with SE were included. Ten children had DS, and 61 had another diagnosis. SCN1A mutations were found in 12 of the 71 patients (16.9%; ten with DS, and two with seizures in a Generalized Epilepsy with Febrile Seizures+(GEFS+) context). The median age at first SE was 8 months in patients with DS, and 41 months in those with another epilepsy syndrome (p<0.001). Nine of the 10 DS patients had their initial SE before 18 months. Among the 26 patients aged 18 months or less at initial SE, the risk of DS was significantly increased for patients with two or more episodes (56.3%), as compared with those who had only one episode (0.0%) (p=0.005). CONCLUSION: In a population of children with SE, patients most likely to have DS are those who present their initial SE episode before 18 months, and who present with recurrent SE episodes.
