Description of an AGPAT2 pathologic allelic variant in a 54-year-old Caucasian woman with Berardinelli-Seip syndrome

A 54-year-old Italian female patient was admitted to our Department with the diagnosis of type 2 diabetes poorly controlled with insulin therapy. The patient was born by consanguineous parents (first degree cousins); she had acromegaloid features, diffuse lipoatrophy and muscular pseudo-hypertrophy since childhood. To confirm the clinical hypothesis of congenital generalized lipodystrophy (CGL) or Berardinelli-Seip syndrome, the sequences of AGPAT2 (encoding for 1-acyl-sn-glycerol-3-phosphate acyltransferase beta) and BSCL2 (encoding for seipin) candidate genes were analyzed. DNA analysis showed the presence of a homozygous mutation in exon 3 of the AGPAT2 gene (P112L). This is the first description of a Caucasian subject with CGL who carries the pathologic allelic variant P112L of the AGPAT2 gene.

Serotonin transporter (SERT) and translocator protein (TSPO) expression in the obese ob/ob mouse

Background

An ever growing body of evidences is emerging concerning metabolism hormones, neurotransmitters or stress-related biomarkers as effective modulators of eating behavior and body weight in mammals. The present study sought at examining the density and affinity of two proteins related to neurotransmission and cell metabolism, the serotonin transporter SERT and the cholesterol import-benzodiazepine site TSPO (translocator protein), in a rodent leptin-lacking mutant, the obese ob/ob mouse. Binding studies were thus carried out in brain or peripheral tissues, blood platelets (SERT) and kidneys (TSPO), of ob/ob and WT mice supplied with a standard diet, using the selective radiochemical ligands [³H]-paroxetine and [³H]-PK11195.

Results

We observed comparable SERT number or affinity in brain and platelets of ob/ob and WT mice, whilst a significantly higher [³H]-PK11195 density was reported in the brain of ob/ob animals. TSPO binding parameters were similar in the kidneys of all tested mice. By [³H]-PK11195 autoradiography of coronal hypothalamic-hippocampal sections, an increased TSPO signal was detected in the dentate gyrus (hippocampus) and choroids plexus of ob/ob mice, without appreciable changes in the cortex or hypothalamic-thalamic regions.

Conclusions

These findings show that TSPO expression is up-regulated in cerebral regions of ob/ob leptin-deficient mice, suggesting a role of the translocator protein in leptin-dependent CNS trophism and metabolism. Unchanged SERT in mutant mice is discussed herein in the context of previous literature as the forerunner to a deeper biochemical investigation.

Artificial neural networks in the outcome prediction of adjustable gastric banding in obese women

BACKGROUND

Obesity is unanimously regarded as a global epidemic and a major contributing factor to the development of many common illnesses. Laparoscopic Adjustable Gastric Banding (LAGB) is one of the most popular surgical approaches worldwide. Yet, substantial variability in the results and significant rate of failure can be expected, and it is still debated which categories of patients are better suited to this type of bariatric procedure. The aim of this study was to build a statistical model based on both psychological and physical data to predict weight loss in obese patients treated by LAGB, and to provide a valuable instrument for the selection of patients that may benefit from this procedure.

METHODOLOGY/PRINCIPAL FINDINGS

The study population consisted of 172 obese women, with a mean ± SD presurgical and postsurgical Body Mass Index (BMI) of 42.5 ± 5.1 and 32.4 ± 4.8 kg/m(2), respectively. Subjects were administered the comprehensive test of psychopathology Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Main goal of the study was to use presurgical data to predict individual therapeutical outcome in terms of Excess Weight Loss (EWL) after 2 years. Multiple linear regression analysis using the MMPI-2 scores, BMI and age was performed to determine the variables that best predicted the EWL. Based on the selected variables including age, and 3 psychometric scales, Artificial Neural Networks (ANNs) were employed to improve the goodness of prediction. Linear and non linear models were compared in their classification and prediction tasks: non linear model resulted to be better at data fitting (36% vs. 10% variance explained, respectively) and provided more reliable parameters for accuracy and mis-classification rates (70% and 30% vs. 66% and 34%, respectively).

CONCLUSIONS/SIGNIFICANCE

ANN models can be successfully applied for prediction of weight loss in obese women treated by LAGB. This approach may constitute a valuable tool for selection of the best candidates for surgery, taking advantage of an integrated multidisciplinary approach.

Acute exogenous TSH administration stimulates leptin secretion in vivo

TSH-receptor (TSHR) has been found in a variety of cell types, including preadipocytes and adipocytes. In vitro, TSH-mediated preadipocyte and adipocyte responses include proliferation, differentiation, survival, and lipolysis. Objective To measure the response of serum leptin to exogenous administration of recombinant human TSH (rhTSH) in vivo. Patients One hundred patients with differentiated thyroid cancer already treated by total thyroidectomy and (131)I remnant ablation were enrolled. Mean (+/-s.e.m.) body mass index (BMI) was 26.9+/-0.6 kg/m(2). Methods Patients received a standard dose of rhTSH for measurement of thyroglobulin in the follow-up of their disease. Blood samples were taken for the assay of TSH and leptin before the first administration of rhTSH (time 0), and 24 h (time 1), 48 h (time 2), 72 h (time 3), and 96 h (time 4) after the first administration of rhTSH. Results Significant mean serum leptin increments, with respect to basal value, were 16, 13, 18, and 11% at times 1, 2, 3, and 4 respectively. Significant positive correlations of leptin-area under the curve with respect to basal leptin levels (r=0.43; P<0.0001) and BMI (r=0.32; P<0.005) were observed. Conclusions Acute rhTSH administration in hypothyroid subjects under l-thyroxine therapy produces a rise in serum leptin. This increase is proportional to the adipose mass suggesting that a functioning TSHR is expressed on the surface of adipocytes. The role that TSHR activation in adipocytes might play in physiological and pathological conditions remains a matter of investigation.

Human serotonin transporter expression during megakaryocytic differentiation of MEG-01 cells

The serotonin (5-HT) transporter (SERT) has been found altered in platelets of patients with genetically complex disorders, including mood-anxiety, pain and eating disorders. In this study, we used cell cultures of platelet precursors as models of investigation on mechanisms of SERT regulation: SERT expression was appraised during megakaryocytic differentiation of human megakaryoblastic MEG-01 cells. Cells were cultured for 8 days with 10(-7)M 4-beta-12-tetradecanoylphorbol-13-acetate (beta-TPA) in the presence of 10% fetal bovine serum (FBS) and SERT was assessed by real time PCR, immunofluorescence microscopy, Western blot and [(3)H]5-HT re-uptake. Results revealed that SERT is present in control-untreated MEG-01 cells. beta-TPA-differentiating MEG-01 cells showed a redistribution of SERT fluorescence, diffuse to cell bodies and blebs along with a 3-fold SERT mRNA increase and a moderate raise in SERT protein (1.5/1.4-fold) by immunoblot and re-uptake assays. In summary, we have shown herein that control megakaryoblasts express the SERT protein. SERT is modulated by differentiation events, implying that SERT density in platelets is under the control of megakaryocytopoiesis stages. Differentiation of MEG-01 cells can provide considerable insight into interactions between SERT genetics, transmitter-hormonal/homeostatic mechanisms and signaling pathways.

The obesity and inflammatory marker haptoglobin attracts monocytes via interaction with chemokine (C-C motif) receptor 2 (CCR2)

Background

Obesity is a chronic low inflammatory state. In the obesity condition the white adipose tissue (WAT) is massively infiltrated with monocytes/macrophages, and the nature of the signals recruiting these inflammatory cells has yet to be fully elucidated. Haptoglobin (Hp) is an inflammatory marker and its expression is induced in the WAT of obese subjects. In an effort to elucidate the biological significance of Hp presence in the WAT and of its upregulation in obesity we formulated the hypothesis that Hp may serve as a macrophage chemoattractant.

Results

We demonstrated by chemotaxis assay that Hp is able to attract chemokine (C-C motif) receptor 2 (CCR2)-transfected pre-B lymphocytes and monocytes in a dose-dependent manner. Moreover, Hp-mediated migration of monocytes is impaired by CCR2-specific inhibition or previous cell exposure to monocyte chemoattractant protein 1 (MCP1) (also known as CCR2 ligand or chemokine (C-C motif) ligand 2 (CCL2)). Downstream effects of Hp/CCR2 interaction were also investigated: flow cytometry proved that monocytes treated with Hp show reduced CCR2 expression on their surface; Hp interaction induces calcium release that is reduced upon pretreatment with CCR2 antagonist; extracellular signal-regulated kinase (ERK)1/2, a signal transducer activated by CCR2, is phosphorylated following Hp treatment and this phosphorylation is reduced when cells are pretreated with a specific CCR2 inhibitor. Consistently, blocking the ERK1/2 pathway with U0126, the selective inhibitor of the ERK upstream mitogen-activated protein (MAP)-ERK kinase (MEK), results in a dramatic reduction (by almost 100%) of the capability of Hp to induce monocyte migration.

Conclusions

Our data show that Hp is a novel monocyte chemoattractant and that its chemotactic potential is mediated, at least in part. by its interaction with CCR2.

An Ischaemic Thalamic Lesion Extending to the Mammillothalamic Tract Associated with Absent Ipsilateral Mammillary Body in a Patient with Temporal Lobe Epilepsy

We describe a patient with right temporal lobe epilepsy with MR findings of an ischaemic thalamic lesion extending to the mammillothalamic tract and absent visualization of the mammillary body without signal changes in the hippocampus.

CT Diagnosis of Cerebral Venous Thrombosis: Importance of the First Examination for Fast Treatment

This study is a retrospective investigation of the role of non contrast-enhanced CT (NCCT) in the diagnosis of cerebral venous thrombosis (CVT) in clinical practice. We retrospectively identified 24 patients discharged with a diagnosis of CVT between January 2002 and December 2008 who had undergone NCCT as the first imaging modality. NCCT had been evaluated by a general radiologist and subsequently by a neuroradiologist in five cases. Final diagnosis was established by CT angiography (CTA), magnetic resonance (MR) and digital subtraction angiography (DSA). NCCT diagnosis was defined as "positive" when the neuroradiologist suggested the diagnosis of CVT on the report, as opposed to the "negative" diagnosis group. All NCCT examinations were reviewed by a neuroradiologist experienced in cerebrovascular pathology. We compared his evaluation and analysed the location and number of direct signs found on NCCT. The neuroradiologist strongly suggested an NCCT diagnosis of CVT in 63% (15/24) of patients: 80% (4/5) with deep venous thrombosis (DVT) and 57% (11/19) with sinus venous thrombosis (SVT). The general radiologist's NCCT evaluation was incorrect in four cases, subsequently diagnosed at NCCT by the neuroradiologist. After reviewing the NCCT examination the experienced neuroradiologist identified the CVT direct sign in two that belonged to the NCCT negative diagnosis group. Thus the direct sign was present in 71% (17/24) of the cases: all the patients with DVT and 63% (12/19) of the patients with SVT. NCCT still plays an important role for fast and accurate diagnosis of CVT in the emergency setting. NCCT displayed the CVT direct sign more frequently than previously thought and it was correctly interpreted in most cases. Neuroradiological consultation adds value to the general radiologist's evaluation.

Melanocortin-4 receptor mutations in obesity

The current alarming spread of obesity in many parts of the world is caused by a sudden environmental shift characterized by replacement of a frugal diet with low cost, energy dense food, and little requests for physical activity during work and leisure time. Yet, not all people exposed to an obesogenic environment become obese, and individual differences in the propensity to gain weight as well as the occurrence of different obese phenotypes within the same environment indicate that the genetic heritage in this regard is significant and heterogeneous. The central melanocortin circuit has received much attention during the past decade, since mutations of genes expressing some key molecules in neurons of this system were discovered, which may cause monogenic forms of obesity in animals and humans. Within the arcuate nucleus of the hypothalamus the prohormone proopiomelanocortin is posttranslationally cleaved to produce the alpha-melanocyte stimulating hormone, a peptide with anorexigenic effects upon activation of the melanocortin-4 receptor (MC4R) expressed on the surface of target neurons. Studies regarding the frequency of MC4R mutations associated with human obesity have provided variable results (up to 6% of obese subjects). Various findings suggest an oligogenic and codominant mode of inheritance for MC4R deficiency, with modulation of expressivity and penetrance of the phenotype. The yield of MC4R testing in clinical diagnosis and treatment of obesity is at present undefined since the relatively low prevalence of MC4R pathogenic variants in the general population, along with the high number of sequence variants, has so far compromised the devising of systematic controlled intervention studies. Hopefully, in the future, MC4R testing will have practical implications for the development of new mechanism-based therapy of obesity as well as for the design of specific and more effective protocols, based on lifestyle intervention and current pharmacological or surgical approaches, for management of obesity in MC4R-mutated individuals.

Transnasal OGD: practice survey and impact of a live video retransmission

BACKGROUND

Unsedated transnasal oesogastroduodenoscopy significantly improves patient tolerance compared to unsedated conventional peroral oesogastroduodenoscopy.

AIMS

To assess the adoption of transnasal oesogastroduodenoscopy among endoscopists from various European countries and its determinants.

METHODS

A survey was distributed to 624 endoscopists attending a live course on digestive endoscopy; a poll was also performed immediately before and after live video retransmission of a transnasal oesogastroduodenoscopy.

RESULTS

Answer rate was 48%; transnasal oesogastroduodenoscopy was practised by 31% of respondents. In multivariate analysis, practice of transnasal oesogastroduodenoscopy was associated with location in France and Netherlands (P<0.0001), availability of many gastroscopes (P<0.0001) and less frequent use of sedation (P=0.006). Endoscopists who did not practise transnasal oesogastroduodenoscopy cited doubts about its advantages over conventional oesogastroduodenoscopy and lack of training (34% each) as barriers to adoption. Seventy-four percent of endoscopists practicing transnasal oesogastroduodenoscopy did actually use it in <20% of eligible cases. Live video retransmission of a transnasal oesogastroduodenoscopy increased the proportion of endoscopists interested in this technique (P=0.006).

CONCLUSIONS

Adoption of transnasal oesogastroduodenoscopy largely varies between European countries; endoscopists practicing this technique use it in a minority of eligible cases. Live case demonstration may decrease barriers to the adoption of this technique.

Electromagnetic fields produced by incubators influence heart rate variability in newborns

BACKGROUND

Incubators are largely used to preserve preterm and sick babies from postnatal stressors, but their motors produce high electromagnetic fields (EMFs). Newborns are chronically exposed to these EMFs, but no studies about their effects on the fragile developing neonatal structure exist.

AIM

To verify whether the exposure to incubator motor electric power may alter autonomous nervous system activity in newborns.

MATERIAL AND METHODS

Heart rate variability (HRV) of 43 newborns in incubators was studied. The study group comprised 27 newborns whose HRV was studied throughout three 5-minute periods: with incubator motor on, off, and on again, respectively. Mean HRV values obtained during each period were compared. The control group comprised 16 newborns with constantly unrecordable EMF and exposed to changes in background noise, similar to those provoked by the incubator motor.

RESULTS

Mean (SD) total power and the high-frequency (HF) component of HRV increased significantly (from 87.1 (76.2) ms2 to 183.6 (168.5) ms2) and the mean low-frequency (LF)/HF ratio decreased significantly (from 2.0 (0.5) to 1.5 (0.6)) when the incubator motor was turned off. Basal values (HF = 107.1 (118.1) ms2 and LF/HF = 1.9 (0.6)) were restored when incubators were turned on again. The LF spectral component of HRV showed a statistically significant change only in the second phase of the experiment. Changes in background noise did not provoke any significant change in HRV.

CONCLUSION

EMFs produced by incubators influence newborns' HRV, showing an influence on their autonomous nervous system. More research is needed to assess possible long-term consequences, since premature newborns may be exposed to these high EMFs for months.

Metabolite Changes in Normal Appearing Cervical Spinal Cord in Two Patients with Multiple Sclerosis. A Proton MR Spectroscopic Analysis

We describe two cases of multiple sclerosis (MS) analyzed with Proton MR Spectroscopy ((1)H-MRS) with the voxel placed along the main axis of the normal appearing cervical spinal cord over three main space planes, orthogonally set. Relative concentrations expressed by the absolute concentration ratios of total NAA (tNAA), choline (Cho), myo-inositol (mI) and creatine plus phosphocreatine (Cr) were compared with the metabolites of ten healthy volunteers. We found a significant increase in mI/Cr and a small increase in Cho/Cr in the first patient, whereas the second patient had a decrease in NAA/Cr and NAA/Cho ratios. 1H-MRS will disclose biochemical changes in MS, even in normal appearing spinal cord, as already described in normal appearing cerebral tissue: these biochemical changes may provide significant information on disease prognosis.

Free fatty acids as mediators of adaptive compensatory responses to insulin resistance in dexamethasone-treated rats

BACKGROUND

Chronic low-dose dexamethasone (DEX) treatment in rats is associated to insulin resistance with compensatory hyperinsulinaemia and reduction in food intake. We tested the hypothesis that the elevation in circulating free fatty acids (FFAs) induced by DEX is the common mediator of both insulin resistance and insulin hyperproduction.

METHODS

For this purpose, an anti-lipolytic agent was administered during DEX treatment to lower lipacidaemia for several hours prior to glucose and insulin tolerance tests. Leptin expression in adipose tissue (by Northern blot) and plasma leptin levels (by radioimmunoassay) were also investigated to verify whether a rise in circulating leptin could be responsible for the anorectic effect of DEX.

RESULTS

Our data show that a transient pharmacological reduction of elevated plasma FFA levels abates the post-loading hyperinsulinaemia and counteracts the insulin resistance induced by DEX, supporting the hypothesis that the chronic elevation in FFAs is the common mediator of DEX-induced changes. Despite enhanced leptin expression in white adipose tissue, DEX-treated rats show no significant increase in plasma leptin levels. This suggests that the anorectic effect of DEX should be mediated, at least partially, by other factors, possibly related to the influence of concomitantly elevated plasma FFA and insulin levels on the hypothalamic centers regulating feeding.

CONCLUSIONS

Our results sustain the idea that a prolonged increase in plasma FFA levels plays an important role in the adaptive regulation of glucose and energy homeostasis, not only by potentiating insulin secretion but also by providing a signal of 'nutrient abundance' capable of restraining food intake.

Metabolic findings on 3T 1H-MR spectroscopy in peritumoral brain edema

BACKGROUND AND PURPOSE

Little is known about the metabolic properties of brain edema associated with tumors. This work was conducted on the basis of the assumption that, in the presence of intra-axial and extra-axial brain tumors, the white matter involved by the edema is a site of metabolic change that involves the structure of the myelin sheath.

MATERIALS AND METHODS

Thirteen patients comprised our cohort affected by intra-axial and extra-axial cerebral tumors with a peritumoral T2-weighted MR signal hyperintensity as a result of edema, where MR spectroscopy showed no increase in choline-containing compounds. Measurements on proton MR spectroscopy (1H-MR spectroscopy) were performed with a 3T whole-body scanner with use of a point-resolved spectroscopy sequence for localization (TR, 2000 ms; TE, 35 ms), and the metabolites were quantified with the SAGE method. Peak intensities of the main metabolites were expressed as ratios of one another and were compared with values obtained in the white matter of the left frontal region in a control group of 16 healthy volunteers.

RESULTS

Choline-to-creatine (Cho/Cr) and myo-inositol-to-creatine (mIns/Cr) signal intensity ratios were normal in all patients. N-acetylaspartate-to-creatine (NAA/Cr) and N-acetylaspartate-to-choline (NAA/Cho) ratios decreased in 4 patients. Glutamate plus glutamine-to-creatine (Glx/Cr) was increased in 10 patients. A resonance peak at 3.44 ppm, strongly suggesting the presence of glucose, was detected in all but 1 patient. Lactate was detected in 12 patients and lipids in 5. Moreover, the resonances that pertained to the aliphatic amino acids valine, leucine, and isoleucine were present in 12 patients.

CONCLUSIONS

Our findings on MR spectroscopy confirmed the hypothesis that in the edema surrounding brain tumors, an energy-linked metabolic alteration was associated with injury to the myelin sheath.

Cathepsin K null mice show reduced adiposity during the rapid accumulation of fat stores

Growing evidences indicate that proteases are implicated in adipogenesis and in the onset of obesity. We previously reported that the cysteine protease cathepsin K (ctsk) is overexpressed in the white adipose tissue (WAT) of obese individuals. We herein characterized the WAT and the metabolic phenotype of ctsk deficient animals (ctsk−/−). When the growth rate of ctsk−/− was compared to that of the wild type animals (WT), we could establish a time window (5–8 weeks of age) within which ctsk−/−display significantly lower body weight and WAT size as compared to WT. Such a difference was not observable in older mice. Upon treatment with high fat diet (HFD) for 12 weeks ctsk−/− gained significantly less weight than WT and showed reduced brown adipose tissue, liver mass and a lower percentage of body fat. Plasma triglycerides, cholesterol and leptin were significantly lower in HFD-fed-ctsk−/− as compared to HFD-fed WT animals. Adipocyte lipolysis rates were increased in both young and HFD-fed-ctsk−/−, as compared to WT. Carnitine palmitoyl transferase-1 activity, was higher in mitochondria isolated from the WAT of HFD treated ctsk−/− as compared to WT. Together, these data indicate that ctsk ablation in mice results in reduced body fat content under conditions requiring a rapid accumulation of fat stores. This observation could be partly explained by an increased release and/or utilization of FFA and by an augmented ratio of lipolysis/lipogenesis. These results also demonstrate that under a HFD, ctsk deficiency confers a partial resistance to the development of dyslipidemia.

Is the ABC pain scale reliable for premature babies?

AIM

We recently developed the ABC scale to assess pain in term newborns. The aim of the present study was to assess the reliability of the scale in preterm babies.

MATERIAL AND METHODS

The scale consists of three cry parameters: (a) pitch of the first cry, (b) rhythmicity of the bout of crying and (c) cry constancy. Changes in these parameters were previously found to distinguish medium and high levels of pain as evaluated by spectral analysis of crying. We enrolled 72 babies to perform the steps usually requested to validate a scale, namely the study of the concurrent validity, specificity and sensibility. Moreover, we assessed the interjudge reliability and the clinical utility and ease of the scale.

RESULTS

A good correlation (r = 0.68; r(2)= 0.45; p < 0.0001) was found between scores obtained with the ABC scale and the premature infant pain profile (PIPP) scale, demonstrating a good concurrent validity. The scale also showed good sensitivity and specificity (we found statistically significant differences between mean values of scores obtained in babies who underwent pain and babies who underwent non-painful stimulus.) Interobserver reliability was good: Cohen's kappa = 0.7.

CONCLUSION

The good correlation between the two scales shows that the ABC scale is also reliable for premature babies.

Adjuvant chemotherapy with temozolomide and radiation therapy in patients with high grade gliomas

12534

Background: Temozolomide, a novel alkylating agent, has shown activity in the treatment of patients with high-grade gliomas. The current standard of care for newly diagnosed glioblastoma is surgical resection to the extent feasible, followed by adjuvant chemo- radiotherapy according to Stupp regimen. Methods: We reviewed our experience with a combination of radiotherapy (fractionated focal irradiation in daily fractions of 2 Gy given 5 days per week for 6 weeks, for a total of 60 Gy) plus continuous daily temozolomide (75 mg per square meter of body-surface area per day, 7 days per week from the first to the last day of radiotherapy), followed by six cycles of adjuvant temozolomide (150 to 200 mg per square meter for 5 days during each 28-day cycle). Results: 43 patients , median ECOG PS= 0, were treated with concomitant RT and Temozolomide at our institution since March 2004. Median age was 63 (range 33–73), with 62% over 60 years. All patients had histologically confirmed high grade gliomas: glioblastoma multiforme (32), grade III oligodendroglioma (3), grade III oligoastrocytoma (2), grade III astrocytoma (6). 2/43 patients underwent only a biopsy, the remaining underwent debulking surgery. At a median follow-up of 17 months, the median progression-free survival (PFS) was 6 mo and median overall survival (OS) was 12 mo. Median PFS and median OS were similar in elderly ( = 60 years). Treatment was well tolerated. Only one patient had grade IV haematological toxicity. One patient discontinued treatment due to hepatotoxicity. Conclusions: Our findings confirm the results of the EORTC trial(Stupp R et al., 2005)

Is prenatal bonding enhanced by prenatal education courses?

AIM

Prenatal education courses (PEC) are a way of allaying anxiety in pregnancy. PEC consist of a series of five 1-hour lessons in the first and second trimesters of pregnancy. Conducted by nurses or midwives, the course syllabus includes the basics of fetal physiology and development, singing sessions, dance sessions, massage-through-the-womb sessions. Here we investigated whether they can enhance feto-maternal bonding.

METHODS

We studied 77 pregnant women (mean age: 31.5+/-4.1 years), 36 of whom attended PEC. We used the Prenatal Attachment Inventory (PAI), a validated 21-item questionnaire, to score prenatal bonding and compared the scores of the two groups. Three months after delivery, we asked the mothers to fill in another questionnaire to assess infant and maternal well-being.

RESULTS

The PEC group showed a higher PAI score than the control group (65.5+/-6.9 vs. 59.9+/-6.1; P<0.05). Babies born to the PEC group had a higher frequency of unexplained crying.

CONCLUSION

PEC positively influenced prenatal attachment. More studies are needed to assess whether this may be useful for the development of the mother-infant relationship.

[Cholestasis in adults. 2. Clinical signs and symptomatic treatment]

Cholestasis, a frequent occurrence in clinical practice, can be suspected when confronted to clinical signs (pruritus and jaundice) and/or increased blood level of alkaline phosphatases, gammaglutamyl transpeptidase and/or conjugated bilirubin. This short review will deal with the management of clinical manifestations and extrahepatic complications, whatever the cause of cholestasis. The management according to etiology will be dealt with in a separated chapter.
