Perpetrators', Victims', and Witnesses' Folk Explanations of Aggressive Behaviors.

Unsurprisingly, victims and perpetrators often view aggressive behaviors differently. The current study examined whether victims, perpetrators, and witnesses also explained aggressive behaviors differently. The current study included 408 participants who recalled a time when they harmed another person (i.e., perpetrator memory), when another person harmed them (i.e., victim memory), and when they witnessed an aggressive behavior (i.e., witness memory). Replicating past research, participants rated their recalled aggressive behaviors from the victim perspective as being more harmful and less justified than they did for their recalled behaviors from the perpetrator perspective. When examining their explanations for the behaviors, participants most often explained their own aggressive behaviors by referring to their mental deliberations that led to their behavior (i.e., reason explanations). In comparison, they referred to background causal factors (i.e., causal history of reasons explanations)-such as personality traits, demographic factors, cultural norms, etc.-more when explaining others' aggressive behaviors, especially when the explanation was from the victim perspective. These findings show the subtleties in how people communicate about their aggressive interactions: When communicating about their own aggressive behaviors, people use modes of explanations that portray their behaviors as sensible, and when communicating about a time when another person behaved aggressively towards them, people use modes of explanations that omit the thought processes that led to those behaviors.

Heterotrimetallic Mixed-Valent Molecular Precursors Containing Periodic Table Neighbors: Assignment of Metal Positions and Oxidation States.

A known trinuclear structure was used to design the heterobimetallic mixed-valent, mixed-ligand molecule [CoII (hfac)3 -Na-CoIII (acac)3 ] (1). This was used as a template structure to develop heterotrimetallic molecules [CoII (hfac)3 -Na-FeIII (acac)3 ] (2) and [NiII (hfac)3 -Na-CoIII (acac)3 ] (3) via isovalent site-specific substitution at either of the cobalt positions. Diffraction methods, synchrotron resonant diffraction, and multiple-wavelength anomalous diffraction were applied beyond simple structural investigation to provide an unambiguous assignment of the positions and oxidation states for the periodic table neighbors in the heterometallic assemblies. Molecules of 2 and 3 are true heterotrimetallic rather than a statistical mixture of two heterobimetallic counterparts. Trinuclear platform 1 exhibits flexibility in accommodating a variety of di- and trivalent metals, which can be further utilized in the design of molecular precursors for the NaMM'O4 functional oxide materials.

[Massive recurrent haemoptysis in a pregnant woman with preeclampsia]. / Hémoptysies massives récidivantes chez une femme enceinte avec prééclampsie.

Massive haemoptysis are rare in pregnant woman. Besides usual causes of haemoptysis, cases of idiopathic haemoptysis have been described during pregnancy, probably with a hormonal role. A pregnant woman at 22 weeks amenorrhoea was admitted in intensive care unit for massive and recurrent haemoptysis, enhanced by bouts of hypertension in a context of preeclampsia. Arteriography showed bronchial hypervascularisation, with abnormally dilated bronchial arteries, and a lot of collateral arteries. Three sessions of bronchial artery embolization have been performed with success. The management of idiopathic haemoptysis in pregnant woman seems to be based on the usual algorithm of management, emphasizing on the control of blood pressure, and the key role of interventional radiology.

[Marfan's syndrome and pregnancy]. / Syndrome de Marfan et grossesse.

The Marfan's syndrome is an autosomal dominant genetic disorder resulting in a diminished strength of connective tissue. The ocular, skeletal and cardiovascular systems are mostly at risk. Principal complications of the disease are aortic dilatation and the risk of acute dissection. Pregnancy increases this risk. Based on the experience of our obstetrics department and after reviewing medical literature, we have tried to establish guidelines for obstetric care adapted to pregnant patients affected by Marfan's syndrome. Women with aortic root > 40 mm should avoid pregnancy. In all cases B-adrenergic receptor blockers must be used as soon as possible. Because there is a 50% risk that offspring will inherit the syndrome, prenatal diagnosis should be suggested. In addition to usual pregnancy monitoring, echocardiography should be performed every 3 months as well as 2 months after delivery. No increase of obstetrical complications has been shown in these patients. Route of delivery also depends on the diameter of the aortic root: vaginal delivery is warranted if the aortic root is<40; cesarean section should be performed in the other cases. Thus, with appropriate supervision, women with Marfan's syndrome will tolerate pregnancy without any adverse effect.

[Management of malignant gliomas diagnosed during pregnancy]. / Prise en charge des gliomes malins découverts au cours d'une grossesse.

INTRODUCTION: Glioma is seldom diagnosed during pregnancy. In this situation management presents difficult problems for both neuro-oncologists and obstetricians. We report four cases and discuss the management of this unusual situation. CASE REPORT: The first patient was admitted to hospital at 29 weeks' gestation because of a generalized seizure and a right hemiparesis. MRI showed a left fronto-insular lesion. A stereotactic biopsy was obtained and revealed an anaplastic oligodendroglioma. With corticosteroids the patient remained stable until cesarean delivery at 36 weeks. In post-partum additional treatment with chemotherapy was started. The second patient was hospitalized at 26 weeks' gestation because of cranial hypertension, right hemiparesis and aphasia. MRI showed an important left fronto-parietal lesion. Partial resection was performed at 28 weeks. Histology revealed a glioblastoma multiforme. With corticosteroids the patient remained stable until cesarean delivery at 33 weeks. In post-partum additional treatment with radiotherapy and chemotherapy was started. The third patient was admitted to the hospital at 12 weeks' gestation because of cranial hypertension. MRI showed a left frontal lesion. A subtotal resection was done at 13 weeks. Histology revealed a glioblastoma multiforme. Two weeks after surgery the patient's neurological condition worsened and in agreement with the patient a therapeutic abortion was decided. Afterwards additional treatment with radiotherapy and chemotherapy was started. The last patient received combined treatment with radiotherapy and chemotherapy for local recurrence of a mesencephalic high-grade glioma. A posteriori it was discovered that the patient was at 4 months' gestation during this treatment. Cesarean delivery was done at 36 weeks. The child was normal at birth and is still in good health 5 years later. CONCLUSION: The management of gliomas diagnosed during pregnancy should not be different from the standard management of gliomas in young non-pregnant adults. Pregnant women because of their young age can have a long survival. Their pregnancy should not prevent them from receiving the best treatment for their glioma. Treatment will depend upon clinico-radiological presentation, histology, gestational age and the patient's desires. Generally speaking, surgical resection of high-grade gliomas should not be delayed during pregnancy. Progress in anesthesia and neurosurgery have greatly reduced the risks for the foetus. After delivery, if the delay between surgery and delivery is too long it is possible to begin cerebral radiotherapy during pregnancy. After the first trimester of gestation this treatment can be given without any important risks for the child.

[Cystic fibrosis and pregnancy: report of a twin pregnancy and review of the literature]. / Mucoviscidose et grossesse: á propos d'un cas de grossesse gémellaire et revue de la littérature.

We report here the first published case of twin pregnancy in a woman with cystic fibrosis. This situation will become more and more common because the increased life expectancy of patients with cystic fibrosis and the development of medically assisted procreation. Conception of this twin pregnancy was medically assisted in a cystic fibrosis woman with moderate pulmonary disease. This observation is in accordance with several recent reports dealing with single pregnancies: morbidity, mortality and degradation of lung function have not been found to increase. The only effect of cystic fibrosis on pregnancy is an increased risk of preterm delivery. There is thus no systematic contraindication to pregnancy among women with cystic fibrosis provided that they are given attentive care by a multidisciplinary team. Genetic counselling and prenatal diagnosis also have an important role to play.

[Compliance with a protocol of prevention of neonatal group B streptococcal sepsis in the Aurore perinatal network]. / Application d'un protocole de prévention de l'infection materno-foetale à streptocoque B hémolytique au sein du réseau périnatal Aurore.

OBJECTIVE: Our purpose was to measure the compliance with the network hospitals protocol for preventing neonatal group B streptococcal sepsis. MATERIALS AND METHOD: All vaginal deliveries during a one-week period in 37 maternities of the perinatal network were reviewed retrospectively. RESULTS: A total of 752 records were reviewed. Compliance with the protocol regarding the time of culture was 91.1%. Overall, prevalence of group B streptococcal carriage was 14.2%. Among patients eligible for intrapartum antibiotics, 46.4% received adequate prophylaxis. Considering the length of labor, one out of two patients could have received intrapartum adequate antibiotics. Regarding newborns, 86.1% received adequate medical surveillance. There was no confirmed case of group B streptococcal sepsis during the week of study. CONCLUSION: All the maternities of network Aurore accepted and adopted evaluation principle. Some elements of protocol could be better applied, in particular delivering adequate intrapartum antibiotic prophylaxis.

Amniotic fluid embolism during caesarean section.

Amniotic fluid embolism occurs rarely but is a leading cause of maternal mortality. A high index of clinical suspicion is necessary to make an early diagnosis to reduce morbidity and mortality. We report a non-fatal case of amniotic fluid embolism occurring during a caesarean section, with special emphasis on the mode of development and diagnosis. The initial presentation of this syndrome was a coagulopathy, followed by the usual complications of massive bleeding. Although non-specific, the diagnosis of amniotic fluid embolism was supported by the observation of amniotic fluid in the central venous blood as well as in the broncho-alveolar fluid.

Renal outcome of children exposed to cyclosporine in utero.

The number of pregnancies in immunosuppressed women has increased during the recent years and this has become a major part of the rehabilitation and quality of life of treated patients. Most of them are organ transplant recipients and large series from the literature have shown that children born to such women may present with intrauterine growth retardation, a condition which may be associated with significant reduction in nephron number and oligomeganephronia. On the other hand, experimental data in animals have demonstrated that in utero exposure to CsA may alter nephrogenesis and further alter renal function. Therefore offspring of organ transplant women treated with CsA exhibit a theoretical risk of renal impairment, due to both IUGR and fetal nephrotoxicity. However, despite the limited experience of long term studies in children, there is no evidence of any significant deleterious adverse effect of in utero exposure to CsA. However further studies based on large series are required in order to demonstrate that renal fetal effects have limited clinical consequences.

Planned vaginal delivery versus elective caesarean section in singleton term breech presentation: a study of 1116 cases.

OBJECTIVE: To compare neonatal and maternal morbidity and mortality between planned vaginal delivery and elective cesarean section for singleton term breech presentation. STUDY DESIGN: We studied retrospectively all deliveries of singleton breech presentations at term in the public Hospitals of Lyon between 1 January 1991 and 31 December 1995. To take only the effect of delivery on the fetus into account, we eliminated high risk pregnancies and fetal malformations. Fetal parameters were corrected perinatal mortality, Apgar score<7 at 1 and 5 min, umbilical cord arterial pH<7.15, neurological disorders, trauma and need for neonatal intensive care. Maternal parameters were mild, moderate and severe complications. RESULTS: Of the 1116 breech presentations, 702 (62.9%) underwent an elective caesarean section and 414 (37.1%) a planned vaginal delivery. In the latter group, 342 (30.6%) had a vaginal delivery and 72 (6.5%) a non-elective caesarean section. Infants for whom the vaginal route was planned were at higher risk of mortality and morbidity. There were 2 deaths in this group and none in the elective caesarean section group and all fetal parameters were poorer: more Apgar<7 at 5 min (RR: relative risk=3.05; 1.03-9.05), arterial pH<7.15 (RR=1.64; 1.11-2.43), intubations (RR=7.35; 2.10-25.6), neurological disorders, trauma (RR=4.24; 1.66-10.8), transfer to intensive care units (RR=3.23; 1.57-6.64). The overall maternal morbidity was lower in the planned vaginal delivery group (RR=0.65; 0.44-0.94) but this was only because of less mild complications. The moderate and severe complications were the same in the two groups (RR=0.97; 0.59-1.57). CONCLUSIONS: Planned vaginal delivery in singleton term breech presentation increases the risk of death and of neonatal complications. Elective caesarean section increases the risk of only mild maternal complications. For these reasons, elective caesarean section should be preferred for singleton term breech presentations.

New insights into the postnatal growth of infants born 'idiopathic' small for gestational age.

Infants born small for gestational age (SGA) are defined as those with a birth weight and/or birth length below two standard deviations for gestational age. Postnatal catch-up growth is absent in 8-12% of children born SGA and these children achieve adult heights far below their target height. The objectives of our retrospective study were to confirm the prevalence of catch-up growth and to refine the kinetics of the catch-up process. The 'Lyon series' of patients consisted of 179 children with 'idiopathic' SGA, of whom 8% did not achieve catch-up growth (i.e. their height remained below -2 SD throughout the study). The number of days that the mother was hospitalized before delivery was found to be significantly correlated with lack of catch-up growth. Maternal hypertension, term delivery and postnatal parenteral nutrition were also associated with lack of catch-up growth, but the relationship was not significant. In addition, an oscillatory growth velocity pattern was observed in boys and girls born SGA, with alternating periods of growth acceleration and deceleration. This suggests that catch-up growth is regulated in a sophisticated way by the hypothetical 'Somatostat', although further confirmation of this process is needed.

Renal function of children exposed to cyclosporin in utero.

BACKGROUND: The use of cyclosporin (CsA) has improved graft survival in transplant (Tx) patients despite its potential nephrotoxicity. Children born to transplanted women may present with intrauterine growth retardation (IUGR). On the basis of potential reduced nephron mass both in IUGR and in newborn experimental animals exposed to CsA in utero, we investigated the renal function of children >1 year of age born to women under maintenance immunosuppression, including CsA. METHODS: Fourteen children born to 12 Tx women (nine kidney, one pancreas-kidney, one heart, one liver) were investigated using inulin clearance (C(in)), para-aminohippuric acid clearance (C(PAH)), microalbuminuria, and electrolyte reabsorption rate. RESULTS: Gestational age of the 14 infants was 34+/-3 weeks and birth weight 2018+/-620 g. During pregnancy, CsA trough blood level was 234+/-115 microg/l and plasma creatinine range was 96-136 micromol/l. Two children were excluded from the study because renal investigation led to a diagnosis of hereditary nephritis (one Alport syndrome, one familial dominant focal segmental glomerulosclerosis) that was retrospectively completed in the mother. Renal function tests were finally performed in 12 children at 2.6+/-1.8 years of age: BP 94+/-7/55+/-5 mmHg, C(in) 117+/-28 ml/min/1.73 m(2), C(PAH) 545+/-124 ml/min/1.73 m(2), filtration fraction 0.23+/-0.03, microalbuminuria 4.2+/-3.5 mg/mmol. Electrolyte tubular reabsorption rates and urine concentrating capacity were normal. CONCLUSION: These results suggest that in children born to transplanted women taking CsA, renal function develops normally despite prolonged exposure in utero.

[The migrating intrauterine device. Case report and review of the literature]. / Le stérilet migrateur. A propos d'un cas et revue de la littérature.

We report a case of migration of an intrauterine contraceptive device (IUCD) detected during pregnancy one year after insertion. The advanced gestation of the pregnancy and the absence of symptoms lead to expectant management. There were no complications during the pregnancy or delivery. A CT Scan in the post-partum period suggested that the IUCD was located in the region of the small bowel. Laparoscopy confirmed that the IUCD was superficially embedded in the intestinal wall but with no mucosal lesion. The device was removed with the aid of a mini-laparotomy. The migration of an IUCD into the abdominal cavity is rare. A literature review spanning the past 18 years revealed 165 reported cases. The IUCD was located in the following sites: omentum 45, rectosigmoid 44, peritoneum 41, bladder 23, appendix eight, small bowel two, adnexa one, iliac vein one. The majority of the authors recommend removal of copper containing devices, because of the potential for inflammatory reactions that can cause bowel obstruction and perforation. Initial laparoscopy has mostly superceded laparotomy but conversion may be necessary if difficulties arise.

Hypertrophic cardiomyopathy and pregnancy.

The case of a young primiparous woman with defibrillator-assisted familial hypertrophic cardiomyopathy (HCM) has led us to review the literature on this pathology, which is exceptional because of its scarcity and the originality of the problems encountered. To our knowledge, this is the first observation ever reported of defibrillator-assisted activation during pregnancy in a woman with HCM. Several questions raised from this particular case, e.g. what are the risks caused by pregnancy in these patients, what is the impact of therapeutics, does the activation of an internal defibrillator involve particular risks, what is the best disposition for delivery and what are the risks for fetuses? We have tried to ask all of these questions, using as exhaustive a literature review as possible.
