Handcrafted firearm suicide: About the unusual use of a mole gun

The body of a man was found in a workshop at the back of his home, a metal pipe embedded in his chest. In the immediate vicinity of the body, among various tools, was a machine containing a holster hit of lead shot evoking a mole-trap-type "taupe gun" (mole gun). The findings at the scene and the presence of a metal tube, sinkers, and a flock in the chest are in favour of the use of a homemade firearm. The autopsy and CT scan revealed atypical ballistic thoracic trauma responsible for a dilaceration of both the heart and thoracic aorta that caused the death. The autopsy also found a contused wound at the back of the skull without intracranial lesion, which may be due to the fall of the victim after the thoracic trauma. There is no other traumatic lesion and in particular no lesion of seizure, constraint, or defense. Toxicological analyses revealed the presence of alcoholic impregnation at the time of death. These findings, confronted with the expertise of a balistician, made it possible to understand how the victim used a mole gun to cause these lesions. A metal tube was used as a cannon to aim more surely at the heart but also as a means of triggering the propulsion mechanism of the trap without having to stretch out the arm. The tube, thinner than the barrel, had disengaged from its tip to be embedded with the lead shot in the chest of the victim.

[Posttraumatic growth in survivors of intimate partner violence: A French pilot study]

OBJECTIVE

This study aimed to: (1) evaluate posttraumatic growth in survivors of intimate partner violence, (2) compare and characterize this posttraumatic growth with the one measured in survivors of other types of violence, and (3) evaluate post-traumatic stress disorder and its relationship with posttraumatic growth in our clinical population.

METHODS

We realized a monocentric pilot study in Poitiers (Vienne, France) recruiting 17 survivors of intimate partner violence and 42 survivors of other types of violence from two medical departments: the Unit of Forensic Medicine, where victims are oriented following complaints, and the Psychotrauma Center. Participants were administrated questionnaires comprising socio-demographics data and specific scales, namely the PTGI and PCL-5.

RESULTS

We found a higher prevalence of posttraumatic growth in survivors of intimate partner violence (82 %), when compared with survivors of sexual assault and other interpersonal types of violence (52 % and 53 %, respectively). Posttraumatic growth was low to moderate, and faster as it was detected in victims recruited in the Unit of Forensic Medicine. All domains of posttraumatic growth were positively affected, i.e. higher scores from the PTGI were recorded in survivors of intimate partner violence. No difference was found when results were compared between groups from the Psychotrauma Center. We were unable to identify socio-demographic predictors of posttraumatic growth. À posttraumatic stress disorder was found in survivors of intimate partner violence, and negatively related to posttraumatic growth.

DISCUSSION

To our knowledge, this is the first study comparing post-traumatic growth across such conditions and using specific and recognized scales. Our pilot study demonstrated that survivors of intimate partner violence were able to develop low to moderate posttraumatic growth faster than survivors of other types of violence. All domains of posttraumatic growth were affected, demonstrating the ability of survivors to withstand adversity. Scientific data regarding the link between posttraumatic growth and posttraumatic stress disorder is unclear, probably depending on the trauma, the circumstances, the timing of the measurement. In our study, we found a clear negative correlation between the two parameters. Our results underline the necessity to provide overall and rapid intervention in survivors of intimate partner violence, comprising legal, psychological, social and medical approaches, to facilitate the development of posttraumatic growth.

[Post-traumatic growth: Some conceptual considerations]

OBJECTIVE

Post-traumatic growth (PTG) is a quite new concept of positive psychology proposed in the mid-1990s which is still rather confidential in France. This article aims to propose a full description of this concept from an historical view to epidemiological data through underlying mechanisms and evaluation.

METHODS

A literature search identifying relevant results was performed through the Pubmed database.

RESULTS

PTG refers to positive psychological changes experienced as a result of a traumatic life event in order to rise to a higher level of functioning. That is to say that people experiencing psychological struggle following adversity may often see positive outcomes in the aftermath of trauma. Domains of PTG include appreciation of life, relationships with others, new possibilities in life, personal strength and spiritual change. A self-report scale, the Post-Traumatic Growth Inventory (PTGI), has been developed. PTG has been demonstrated after various traumatic events such as transport accidents, natural disasters, interpersonal violence or medical problems, with a prevalence ranging from 3 to 98 % depending on the type of trauma.

DISCUSSION

The concept of resilience and some evaluation bias may have been deleterious for the development of the PTG concept in the French-speaking world. There is a need to consolidate data to understand the pathway leading to PTG, noticeably to identify factors contributing to PTG that can help to promote the growth as a new therapy for trauma.

FC02-03 - Is there an association between neurocognitive factors and homicide in schizophrenia ?

Objective

The objective of this systematic review was to investigate which specific and especially neurocognitive factors related to schizophrenia, were associated with homicide risk.

Methods

A systematic English-French Medline literature search of cohort studies, case-control studies and transversal studies published from January 1999 to December 2009 was performed combining the MeSH terms “schizophrenia”, “homicide”, “violence”, “mental process”, “cognition”, “risk”, “risk factors”,. Abstract selection was based on the STROBE checklist for observational studies and on the consort statement for clinical trials.

Results

Of the 366 selected studies, 65 observational or prospective studies, 10 systematic reviews and meta-analysis and 2 interventional studies met the selection criteria and were included in the final analysis. Firstly, we highlighted that historical (past violence, juvenile detention, physical abuse, parental arrest record), dispositional (male gender, young age, low socioeconomic status) and contextual (recent divorce, unemployment, victimisation) factors could be considered as general homicide-related factors. Clinical factors (clinical paranoid, delusions of persecution or thought insertion, substance abuse, disorganized thinking, long duration of untreated psychosis, stopped monitoring or treatment) were more schizophrenia-specific factors for homicide. Most of the excess risk appears to be mediated by substance abuse. Secondly, our results suggested that schizophrenics with a history of aggressive behaviour compared to those without such history, had better performances on global neuropsychological tests exploring executive functions but performed more poorly as considering orbitofrontal functions.

Conclusions

We suggest that every comprehensive psychiatric assessment should explore the risk of homicide, including historical, dispositional, contextual, clinical and neurocognitive (low insight capacity, impaired frontal functions) factors of violence.

Les hommes auteurs d’homicide conjugal

Introduction.

L’homicide conjugal est commis sur un partenaire ou un ex-partenaire de vie intime quel que soit son statut. Il représente environ 20 % des homicides en France [1]. D’origine multifactorielle, son repérage est complexe.

Objectif.

– Mettre en évidence les caractéristiques socio-démographiques, psychopathologiques et criminologiques des hommes auteurs d’homicide conjugal, afin de déterminer des facteurs prédictifs de passage à l’acte.

Méthode.

Étude descriptive et rétrospective sur 37 dossiers d’homicide conjugal (ou tentative), jugés entre 1999 et 2010 par la Cour d’Appel de Poitiers. Un nombre important de variables concernant les auteurs, les victimes et les faits a été recherché. Elles ont ensuite été recoupées pour établir des profils.

Résultats

Les hommes représentent 88 % des auteurs d’homicide conjugaux. Ils sont pour la plupart impulsifs (80,4 %) et présentent des antécédents judiciaires (64,8 %) et de violence conjugale physique (70,3 %). La moitié abuse de l’alcool. Le passage à l’acte est souvent motivé par la séparation du couple (64,8 %). Il est fréquemment commis avec une violence exagérée (54 %). Auparavant, environ la moitié des auteurs avait exprimé des menaces de mort ou suicidaires.

Conclusion

Notre étude a montré que l’homicide conjugal est un geste non prémédité, commis par des hommes, devant la difficulté à accepter la perte de la compagne. Ce crime est souvent associé à la violence conjugale et l’éthylisme chronique. La mise en évidence de ces profils permet de proposer des actes de prévention plus ciblés.

[Autopsy legal under the law]

Only a physician specialized in forensic medicine is allowed to process a autopsy legal. The 2011 reform of forensic medicine aimed to homogenize and enhance thanatological practices over French state territory. According to the law, biological samples withdrawn during an autopsy can't be given back to the families after analysis(art. 230-30 CPP). Respecting the human body and restoring their physical aspect are mandatory by law (art. 230-29 CPP). After a autopsy legal, dead bodies must be given back to their relatives as soon as possible.

Personality disorders, but not cancer severity or treatment type, are risk factors for later generalised anxiety disorder and major depressive disorder in non metastatic breast cancer patients

This study aimed to determine whether personality disorders were associated with later Major Depressive Disorder (MDD) or Generalised Anxiety Disorder (GAD) in breast cancer patients. This longitudinal and multicentric study included 120 French non-metastatic breast cancer patients. After cancer diagnosis (T1) and 7 months after diagnosis (T3), we assessed MDD and GAD (Mini International Neuropsychiatric Interview 5.0). We assessed personality disorders 3 months after diagnosis (VKP). We used multiple logistic regression analysis to determine what were the factors associated with GAD and MDD at T3. At T3, prevalence rate was 10.8% for MDD and 19.2% for GAD. GAD at T3 was significantly and independently associated with GAD at T1 and with existence of a personality disorder, no matter the cluster type. MDD at T3 was significantly and independently associated with MDD at T1 and with the existence of a cluster C personality disorder. Initial cancer severity and the type of treatment used were not associated with GAD or MDD at T3. Breast cancer patients with personality disorders are at higher risk for GAD and MDD at the end of treatment. Patients with GAD should be screened for personality disorders. Specific interventions for patients with personality disorders could prevent psychiatric disorders.

Major depressive disorder, personality disorders, and coping strategies are independent risk factors for lower quality of life in non-metastatic breast cancer patients

OBJECTIVE

Our aim was to identify risk factors for lower quality of life (QOL) in non-metastatic breast cancer patients.

METHODS

Our study included 120 patients from the University Hospital Centers of Tours and Poitiers. This cross-sectional study was conducted 7 months after patients' breast cancer diagnosis and assessed QOL (Quality of Life Questionnaire Core 30 = QLQ-C30), socio-demographic characteristics, coping strategies (Brief-COPE), physiological and biological variables (e.g., initial tumor severity and types of treatment received), the existence of major depressive disorder (Mini International Neuropsychiatric Interview), and pain severity (Questionnaire de Douleur Saint Antoine). We assessed personality disorders 3 months after diagnosis (Vragenlijst voor Kenmerken van de Persoonlijkheid questionnaire). We used multiple linear regression models to determine which factors were associated with physical, emotional, and global QOL.

RESULTS

Lower physical QOL was associated with major depressive disorder, younger age, a more severe initial tumor stage, and the use of the behavioral disengagement coping. Lower emotional QOL was associated with major depressive disorder, the existence of a personality disorder, a more severe pain level, higher use of self-blame, and lower use of acceptance coping strategies. Lower global QOL was associated with major depressive disorder, the existence of a personality disorder, a more severe pain level, higher use of self-blame, lower use of positive reframing coping strategies, and an absence of hormone therapy.

CONCLUSIONS

Lower QOL scores were more strongly associated with variables related to the individual's premorbid psychological characteristics and the manner in which this individual copes with the cancer (e.g., depression, personality, and coping) than to cancer-related variables (e.g., treatment types and cancer severity).

[Homicide, schizophrenia and substance abuse: a complex interaction]

BACKGROUND AND AIM

The prevalence of homicide perpetrators with a diagnosis of schizophrenia is 6% in Western countries populations. The relationship between schizophrenia and homicide is complex and cannot be reduced to a simple causal link. The aim of this systematic review was to clarify the role of substance abuse in the commission of murder in people suffering from schizophrenia.

METHODS

A systematic English-French Medline and EMBASE literature search of cohort studies, case-control studies and transversal studies published between January 2001 and December 2011 was performed, combining the MeSH terms "schizophrenia", "psychotic disorders", "homicide", "violence", "substance use disorder", and the TIAB term "alcohol". Abstract selection was based on the STROBE and PRISMA checklist for observational studies and systematic and meta-analysis studies, respectively.

RESULTS

Of the 471 selected studies, eight prospective studies and six systematic reviews and meta-analysis studies met the selection criteria and were included in the final analysis. Homicide committed by a schizophrenic person is associated with socio-demographic (young age, male gender, low socioeconomic status), historical (history of violence against others), contextual (a stressful event in the year prior to the homicide), and clinical risk factors (severe psychotic symptoms, long duration of untreated psychosis, poor adherence to medication). In comparison to the general population, the risk of homicide is increased 8-fold in schizophrenics with a substance abuse disorder (mainly alcohol abuse) and 2-fold in schizophrenics without any comorbidities. A co-diagnosis of substance abuse allows us to divide the violent schizophrenics into "early-starters" and "late-starters" according to the age of onset of their antisocial and violent behavior. The violence of the "early-starters" is unplanned, usually affects an acquaintance and is not necessarily associated with the schizophrenic symptoms. Substance abuse is frequent and plays an important role in the homicide commission. In addition, the risk of reoffending is high. In the "late-starters", the violence is linked to the psychotic symptoms and is directed to a member of the family. The reoffence risk is low and it depends on the pursuit of care or not.

CONCLUSION

Defining subgroups of violent schizophrenic patients would avoid stigmatization and would help to prevent the risk of homicide by offering a multidisciplinary care which would take into account any substance abuse.

Time-based gene expression programme following diaphragm injury in a rat model

It was hypothesised that diaphragm injury activates a time-based programme of gene expression in muscle repair. Gene expression of different substances, such as proteases (calpain 94 (p94)), transcription factors (myogenin and cFos), growth factors (both basic fibroblast growth factor (bFGF) and insulin-like growth factor (IGF)-II), and structural proteins (myosin heavy chain (MHC) and titin), was quantified by RT-PCR in rat diaphragms exposed to caffeine-induced injury. Injured and noninjured (control) rat hemidiaphragms were excised at different time points (1-240 h). In injured hemidiaphragms, in comparison with control muscles, p94 expression levels peaked at 1 h post-injury (PI), cFos mRNA levels began to rise, after an initial dip, and peaked at 96 h PI, while myogenin mRNA levels started to increase as early as 12 h PI, IGF-II mRNA levels initially decreased until 48 h PI and increased thereafter, peaking at 72 h PI, bFGF mRNA levels rose to a maximum at 96 h PI, and MHC and titin mRNA levels were significantly elevated at 72 h PI. Caffeine-induced diaphragm injury is followed by a time-based expression programme of different genes tailored to meet muscle repair needs.

[Hyaline membrane disease in full-term neonates]

OBJECTIVES

Evaluation of the consequences of preplanned delivery near term on the neonatal respiratory distress syndrome and its mechanism of occurrence.

PATIENTS AND METHODS

During five years, full-term infants (> or =37 weeks gestational age) admitted in the Institut de Puericulture de Paris, with a well characterized hyaline membrane disease, were included in a retrospective study.

RESULTS

During this period, 97 full-term neonates with respiratory distress syndrome were hospitalized in the neonatal intensive care unit. The diagnosis of hyaline membrane disease was made in view of clinical and radiological criteria. The study of mode of delivery has shown a high frequency of pre-planned delivery: 54% caesarean and 24% vaginal delivery. A high-risk of occurrence of hyaline membrane disease was identified around 37 weeks gestational age in the case of preplanned delivery.

CONCLUSION

Preplanned delivery near 37 weeks gestational age may increase the risk of occurrence of hyaline membrane disease in full-term neonates.

Does smoking in pregnancy modify the impact of antenatal steroids on neonatal respiratory distress syndrome? Results of the Epipage study

OBJECTIVES

To assess the relation between cigarette smoking during pregnancy and neonatal respiratory distress syndrome (RDS) in very preterm birth, and to analyse the differential effect of antenatal steroids on RDS among smokers and non-smokers.

DESIGN

A population based cohort study (the French Epipage study).

SETTING

Regionally defined births in France.

METHODS

A total of 858 very preterm liveborn singletons (27-32 completed weeks of gestation) of the French Epipage study were included in this analysis. The odds ratio for RDS in relation to smoking in pregnancy was estimated using a logistic regression to control for gestational age. The odds ratio for RDS in relation to antenatal steroids was estimated taking into account an interaction between antenatal steroids and cigarette smoking, using multiple logistic regression to control for gestational age, birthweight ratio, main causes of preterm birth, mode of delivery, and sex.

RESULTS

The odds ratio for RDS in relation to smoking in pregnancy adjusted for gestational age (aOR) was 0.59 (95% confidence interval (CI) 0.44 to 0.79). The aOR for RDS in relation to antenatal steroids was 0.31 (95% CI 0.19 to 0.49) in babies born to non-smokers and 0.63 (95% CI 0.38 to 1.05) in those born to smokers; the difference was significant (p = 0.04).

CONCLUSIONS

Cigarette smoking during pregnancy is associated with a decrease in the risk of RDS in very preterm babies. Although antenatal steroids reduce the risk of RDS in babies born to both smokers and non-smokers, the reduction is smaller in those born to smokers.

Érythropoïétine chez le nouveau-né : efficacité comparée des voies d’administration sous-cutanée et intraveineuse

OBJECTIVE

Our aim was to compare the effectiveness of a one-month treatment with recombinant human erythropoietine (rHuEpo) according to the administration route.

METHODS

Retrospective study based on the data collection from medical files of 64 preterm infant hospitalized in the "institut de puériculture et de périnatalogie" (Paris) between January 13th, 2002 and April 13th, 2002. The first group (N =33) was treated by subcutaneous rHuEpo 750 IU/kg per week, in three injections by week, for one month. The second group (N =15) was treated by continuous infusion of rHuEpo in total parenteral nutrition 1050 IU/kg per week (30% augmentation to compensate the amount absorbed by the filter). The third group (N =16) received 750 IU/kg per week of rHuEpo in three direct intravenous injections. The effectiveness of rHuEpo was evaluated by the absolute reticulocyte count, the level of hemoglobin and the incidence of blood transfusion (multiple logistic analysis of variant and regression).

RESULTS

The absolute reticulocyte count and hemoglobin level were significantly reduced after one month of treatment by continuous infusion of rHuEpo in total parenteral nutrition and direct intravenous injections compared with a one-month treatment by subcutaneous rHuEpo. Hemoglobine level were at 8.8 and 9.6 g/dl vs 10.3 g/dl (P =0.02) and absolute reticulocyte count at 123,000/mm3 and 190,000/mm3 vs 216,000/mm3 (p =0.001). The number of transfused infants was significantly increased with utilization of continuous (40%) and direct intravenous (75%) compared with those treated by subcutaneous route (21.2%) while the ferritin level and phlebotomy losses were not significantly different in the three groups. The number of blood transfusion was significantly linked to phlebotomy losses and administration route of rHuEpo.

CONCLUSION

Our study tends to demonstrate that rHuEpo administered subcutaneously reduces significantly the number of transfusion in contrary to intravenous routes. Waiting for pilot study and new molecules, we recommend subcutaneous administration of rHuEpo to preterm infants 250 IU/kg three times weekly in the treatment of anemia of prematurity.

[Enteral nutrition for the preterm infant: which maternal milk supplement?]

Different types of human milks are given to preterm newborns (mother and bank milk). Their effect on neonatal growth is recalled. The usefulness and justification of dietetic supplements as well as appropriate quantities and practical aspects are discussed.

Perinatal-lethal Gaucher disease

Gaucher disease is a lysosomal storage disease caused by glucocerebrosidase deficiency. Although purely visceral in most cases, some Gaucher disease patients have neurological signs. Signs of Gaucher disease appear after a symptom-free period, except in rare cases with fetal onset. The description of such cases was based mainly on single reports and siblings. We report here a series of perinatal-lethal Gaucher disease cases highlighting the specificity of this phenotype. We retrospectively studied eight original cases of proven Gaucher disease with fetal onset. Non-immune hydrops fetalis was present in all cases but one, and associated with hepatosplenomegaly, ichthyosis, arthrogryposis, and facial dysmorphy. The similarities between our cases and 33 previously described cases allow us to better delineate the perinatal-lethal Gaucher disease phenotype. Hydrops fetalis, in utero fetal death and neonatal distress are prominent features. When hydrops is absent, neurological involvement begins in the first week and leads to death within three months. Hepatosplenomegaly is a major sign, and associated with ichthyosis, arthrogryposis, and facial dysmorphy in some 35-43% of cases. Perinatal-lethal Gaucher disease is a specific entity defined by its particular course and signs that are absent in classical type 2 Gaucher disease. Our study provides clues to the diagnosis of this likely underdiagnosed condition, which must be biochemically confirmed in order to propose appropriate genetic counselling.

[Medical-legal aspects: the pediatrician as a defendant or as an expert]

Claims concerning management of term intrapartum fetal asphyxia account for nearly 45% of all claims filed against pediatricians practicing in the perinatal setting. We recall here briefly the legal and judiciary context under French law, calling upon ten years experience as a medical expert to describe the principal circumstances and clinical forms of acute intrapartum fetal distress which have lead to claims. A few precautionary and preventive measures which should be taken for the clinical forms of intrapartum fetal asphyxia which carry the greatest risk of claims are presented. Finally, practical elements which should be implemented are proposed if a claim is filled against a pediatrician.

[Neonatal enterovirus myocarditis]

Enterovirus infections in neonates are difficult to diagnose. Diphasic pattern and possibly fatal myocarditis must be anticipated.

CASE REPORT

A 14-day-old girl had presented a heart failure after an initial episode of gastroenteritis and supraventricular tachycardia. Investigation demonstrated global myocardial dysfunction. Diagnosis of neonatal enterovirus myocarditis was made by polymerase chain reaction detection of viral genome. Heart failure was controlled with medical treatment.

CONCLUSION

Enterovirus myocarditis is typically a biphasic illness. Rapid diagnosis of enteroviral infection in neonatal period may be made by polymerase chain reaction detection of viral genome. There is anecdoctal evidence that immunoglobulin infusions may improve outcome.

[Treatment of subclinical congenital toxoplasmosis by sulfadiazine and pyrimethamine continuously during 1 year: apropos of 46 cases]

In France, most of children suffering from congenital toxoplasmosis have an infraclinic or moderate type at birth. This study aimed at evaluating, on the mid term, tolerance and results of postnatal treatment previously given in severe toxoplasmosis.

METHODS

A retrospective study considered 46 children with a mild or moderate congenital toxoplasmosis treated over 12 months with sulfadiazine-pyrimethamine and treatment was completed since three months.

RESULTS

Five children suffered from a lesion of chorioretinitis during treatment and two after. After a mean follow-up of 27.1 months, ten children (21.7% 95%CI [12.1-35.9]) had at least one ocular injury. Specific IgG titers and immune load were diminished to become almost non-existent at the end of the year of treatment (respectively p < 10(-5) and p = 0.0005). No thrombocytopenia was observed. Twenty-three children (50%) had at least one episode of neutropenia < 1000/mm3, 14 had only one, nine presented two or more installment. None was followed by an infection.

CONCLUSION

This therapeutic pathway is more demanding but shorter than those usually offered when associating pyrimethamine-sulfadiazine. Yet, it does give identical result on the mid term. Longer follow-up is needed to appreciate. Active molecule on cysts should be introduced.

Perinatal management of fetal cardiac anomalies in a specialized obstetric-pediatrics center

Perinatal teams dealing with fetal heart disease frequently wonder which pregnancies might be terminated, and when delivery should take place in a specialized surrounding. We present a retrospective study of 229 fetuses, in which prenatal ultrasound showed a cardiac anomaly not compatible with a standard maternity ward delivery. One hundred nineteen pregnancies were terminated (group I) while 110 pregnancies led to the birth of a live baby (group II). Pathology in group I was discovered earlier than in group II (24 vs. 29.3 weeks' gestation; p <0.01), and associated malformations or chromosomal anomalies were much more frequent in group I (80/119 vs. 9/110; p <0.001). Among live born babies, three infants with transposition of the great arteries underwent Rashkind atrioseptostomy in the delivery room. With a minimum follow-up of 12 months, 69 children (63%) have undergone surgery. Among 92 survivors (1 child is lost to follow-up), 78 (71%) are asymptomatic and 14 symptomatic. Early prenatal diagnosis of fetal heart anomalies significantly facilitates prenatal work-up and perinatal care. We present the types of pathology having led to termination and define the situations in which children are at risk of perinatal hemodynamic compromise.

[Perinatal corticosteroid therapy: modalities, efficacy, consequences]

During perinatal period, corticosteroid treatment has two major indications: first antenatally to improve fetal maturity and then to treat postnatal bronchopulmonary dysplasia. Antenatal corticosteroid treatment is widely proved to be efficient in reducing hyaline membrane disease and perinatal mortality incidence. Moreover, it has positive effects on intraventricular hemorrhage incidence, on hemodynamic failure, on persistent patent ductus arteriosus and on necrotizing enterocolitis. Side-effects are few and mild considering expected benefits and they usually occurs after multiple courses. Contra-indications are rare. Bronchopulmonary dysplasia comes with early, important and prolonged inflammatory processes. Corticotherapy allows decreasing significantly length of mechanical ventilation and oxygenotherapy among ventilated premature infants diagnosed with bronchopulmonary dysplasia. In the meantime, acute side-effects are frequent and benefits on mortality rate and long term outcome are not obvious. Main concern remains on possible long-term deleterious consequences on growth, lung and central nervous system development. In this field, clinical data are still insufficient as animal experimentation data promote caution and search for a minimal efficient therapeutic pathway.

[Breastfeeding and hepatitis C virus (HCV): the need for a careful appraisal]

We review the available data on the possible role of breast-feeding in hepatitis C virus (HCV) transmission to infants of HCV-RNA-positive mothers. Current knowledge about HCV excretion through breast milk, HCV infection of breast-fed infants by mothers contaminated after delivery, and vertical transmission risk to infants breast-fed by chronic HCV viremic mothers are presented. Vertical transmission risk by breast-feeding HCV-RNA-positive mothers is unclear: no study has been performed with the aim and the required methodology to evaluate HCV transmission risk related to breast-feeding duration. Recommendations to HCV-RNA-positive mothers who wish to breast-feed their infant are discussed in light of present knowledge about HCV secretion in breast milk, mother-to-infant HCV transmission, and historical records on vertical transmission of other viruses to infants breast-fed by their viremic mothers.

Inhaled salbutamol and beclomethasone for preventing broncho-pulmonary dysplasia: a randomised double-blind study

Early inflammatory lesions and bronchial hyperresponsiveness are characteristics of the respiratory distress in premature neonates and are susceptible to aggravation by assisted ventilation. We hypothesized that treatment with inhaled salbutamol and beclomethasone might be of clinical value in the prevention of bronchopulmonary dysplasia (BPD) in ventilator-dependent premature neonates. The study was double-blinded and placebo controlled. We studied 173 infants of less than 31 weeks of gestational age, who needed ventilatory support at the 10th postnatal day. They were randomised to four groups and received either placebo + placebo, placebo + salbutamol, placebo + beclomethasone or beclomethasone + salbutomol, respectively for 28 days. The major criteria for efficacy were: diagnosis of BPD (with score of severity), mortality, duration of ventilatory support and oxygen therapy. The trial groups were similar with respect to age at entry (9.8-10.1 days), gestational age (27.6-27.8 weeks), birth weight and oxygen dependence. We did not observe any significant effect of treatment on survival, diagnosis and severity of BPD, duration of ventilatory support or oxygen therapy. For instance, the odds-ratio (95% confidence interval) for severe or moderate BPD were 1.04 (0.52-2.06) for inhaled beclomethasone and 1.54 (0.78-3.05) for inhaled salbutamol.

CONCLUSION

This randomised prospective trial does not support the use of treatment with inhaled beclomethasone, salbutamol or their combination in the prevention of BPD in premature ventilated neonates.

Myotonic dystrophy protein kinase gene expression in skeletal muscle from congenitally affected infants

Myotonic dystrophy (DM) is an autosomal dominant neuromuscular disorder characterized by marked variability of its clinical manifestations. The mutational basis of DM is an unstable (CTG)n trinucleotide repeat in the 3' untranslated region of the myotonic dystrophy protein kinase gene (DMPK). We used quantitative RT-PCR to determine DMPK mRNA levels in muscular biopsies from three congenitally affected (CDM) and two control infants. The CDM infants had increased DMPK mRNA levels, which were not correlated to increased expression of the mutant allele. This increase may be the consequence of a maturational muscular arrest, which may maintain an elevated level of DMPK mRNA until birth.

[Cystic adenomatoid malformation of the lung revealed in a newborn infant by an image of a lung abscess]

BACKGROUND

Cystic adenomatoid malformation, a rare pulmonary malformation, usually appears as a cystic mass, radiologically. It may be infected and confusion has also arisen in distinguishing it from pneumonia with pneumatoceles.

CASE REPORTS

A full-term boy suffered from severe neonatal respiratory distress. Pregnancy had been uneventful despite the fact that his mother had insulin-dependent diabetes. Prenatal ultrasonographies did not reveal any abnormality. On day 2, X-rays showed a right pulmonary mass that appeared solid. The patient was treated for E Coli sepsis. Subsequently, the pulmonary mass became lacent, cystic, fluid-filled, resembling an abscess; the CT scan confirmed these features. As the lesion increased in volume, a limited resection was performed. Histologic examination showed adenomatoid proliferation of bronchiolar elements with formation of cysts and necrosis.

CONCLUSION

Infection of cystic adenomatoid malformation may supervene the first days of life resulting in a lung abscess appearance.

[Neonatal hyperglycemia and diabetes mellitus]

BACKGROUND

Hyperglycemia in the neonate may be permanent or more frequently transient. Its treatment is still debated.

PATIENTS AND METHODS

The files of 19 infants with hyperglycemia were retrospectively analysed. Their birth-weights were more than 900 g and their gestational ages more than 27 weeks. Plasma glucose, insulin, C-peptide, islet-cell and insulin autoantibodies were measured in each patient.

RESULTS

Blood glucose ranged from 1.2 to 10 g/l (mean: 5.05 +/- 1.0), between the second hour and the 60th day of life. Four infants presented with permanent neonatal diabetes mellitus: they were small for gestational age. Hyperglycemia was noted from the first day of life. C-peptide levels were less than 0.1 pmol/ml and autoantibodies were absent. Two sibs had hypothyroidism, one patient had unclassifiable chronic diarrhea plus renal disease, the fourth patient had ventricular septal defect. The 15 other patients presented with a transient hyperglycemia that appeared lately (6.1 +/- 3.4 day of life). Hyperglycemia was induced by glucose infusion in five patients, by potentially hyperglycemic drugs in five others. C-peptide levels ranged from 0.01 to 0.76 pmol/ml (mean 0.29 +/- 0.11). One patient and his mother had insulin antibodies. Another patient had congenital heart abnormalities. Hyperglycemia required insulin therapy in 17 cases (four with permanent and 13 with transient hyperglycemia).

CONCLUSION

There are no clinical or biological features permitting foresee the duration of neonatal hyperglycemia. Each patient with birth-weight below 2,500 g should be given insulin when glucosemia remains above 1.3 g/l and his weight does not increase.

[Bronchopulmonary dysplasia. Course over 3 years in 88 children born between 1984 and 1988]

BACKGROUND

The survival and outcome of infants with bronchopulmonary dysplasia (BD) depend on the patient's maturity, the severity of the BD and nutritional problems. This study evaluates the specific role of chronic pulmonary failure in the growth and development of infants recovering from BD.

POPULATION AND METHODS

88 infants admitted for BD from January 1984 to December 1988, having gestational age from 25 to 41 weeks 5 days (mean: 29) and birth weight from 680 to 3,400 g (mean: 1,195) were studied. All infants were given respiratory support for 6 to 914 days (mean 84) and oxygen therapy for 28 to 1,232 days (mean: 119). 29 infants were given corticosteroids for more than 1 month. The outcome of the 80 infants with gestational ages of less than 33 weeks was compared to that of 272 infants with the same gestational age but not suffering from BD on their 28th day. The infants in both groups were examined at 2 years of age and classified as: a) handicapped (neurologic deficit, IQ < 80, hearing loss, blindness, convulsions); b) doubtful (transitory neurology dysfunction); c) normal.

RESULTS

Of the 88 infants still living at the age of 28 days, 19 died before the age of 2 years: 16 of the 64 surviving infants who could be followed until the age of 2 years were classified as handicapped, 13 were considered doubtful and 35 were normal. The more significant risk factors for neurodevelopmental impairment were: a) the presence of porencephaly and/or ventricular dilatation on brain ultrasonography; b) head circumference < -2 SD at the end of hospital stay; c) oxygen therapy and hospitalization > 5-6 months. The group of infants with BD had a higher death rate (24% vs. 3.7 in the group without BD) and more frequent neurodevelopmental impairment at gestational ages of > 31-32 weeks.

CONCLUSIONS

BD is an extra risk for the survival and neurodevelopment of infants with gestational age > 31 weeks.

Intravenous immunoglobulin therapy for prevention of infection in high-risk premature infants: report of a multicenter, double-blind study

The effectiveness of intravenously administered immunoglobulin (Ig) therapy for prophylaxis of infection was evaluated in high-risk preterm infants. Two hundred thirty-five premature newborns were randomly assigned, in a double-blind controlled trial, to treatment and placebo groups. Thirty-five infants (29%) of the Ig group and 29 (25%) of the placebo group had one or more episodes of certain infection. Thirty infants (25%) of the Ig group and 18 (16%) of the placebo group had one or more episodes of probable infection. No significant differences were observed in the incidence of certain or probable infection in treated and control infants. Nevertheless, among the infants who had one or more certain or probable episodes of infection, more of them belonged to the Ig group than to the placebo group. The possible deleterious effect of the administration of large amounts of polyspecific Ig is discussed.
