Violence against women is strongly associated with suicide attempts: Evidence from the WHO multi-country study on women`s health and domestic violence against women

Suicidal behaviours are one of the most important contributors to the global burden of disease among women, but little is known about prevalence and modifiable risk factors in low and middle income countries. We use data from the WHO multi-country study on women`s health and domestic violence against women to examine the prevalence of suicidal thoughts and attempts, and relationships between suicide attempts and mental health status, child sexual abuse, partner violence and other variables. Population representative cross-sectional household surveys were conducted from 2000-2003 in 13 provincial (more rural) and city (urban) sites in Brazil, Ethiopia, japan, Namibia, Peru, Samoa, Serbia, Thailand and Tanzania. 20967 women aged 15-49 years participated. Prevalence of lifetime suicide attempts, lifetime suicidal thoughts, and suicidal thoughts in the past four weeks were calculated, and multivariate logistic regression models were fit to examine factors associated with suicide attempts in each site. Prevalence of lifetime suicide attempts ranged from 0.8% (Tanzania) to 12.0% (Peru city): lifetime thoughts of suicide from 7.2% (Tanzania province) to 29.0% (Peru province), and thoughts in the past four weeks from 1.9% (Serbia) to 13.6% (Peru province). 25-50% of women with suicidal thoughts in the past four weeks had also visited a health worker in that time. The most consistent risk factors for suicide attempts after adjusting for probable common mental health disorders were: intimate partner violence, non-partner physical violence, ever being divorced, separated or widowed, childhood sexual abuse and having a mother who had experienced intimate partner violence. Mental health policies and services must recognise the consistent relationship between violence and suicidality in women in low and middle income countries. Training health sector workers to recognize and respond to the consequences of violence may substantially reduce the health burden associated with suicidal behaviour. (C) 2011 Elsevier Ltd.

Final height of adults with childhood-onset steroid-responsive idiopathic nephrotic syndrome

The aim of this study was to evaluate the final stature of adults with childhood-onset steroid-responsive idiopathic nephrotic syndrome (INS) and the influence of disease-related issues on the achievement of their target heights. We analyzed 60 (41 male) patients and/or their records, with a minimum age of 19 years or at a Tanner`s pubertal stage 4 for boys or status postmenarche for girls, and normal glomerular filtration rate. Mean age at first and last consultation was 5.3 +/- 2.4 years and 20.5 +/- 3.1 years, respectively. Mean follow-up period was 15.10 years. Mean cumulative dose of prednisone was 1254 +/- 831.40 mg/kg. Mean initial and final height Z scores (HtZ) were, respectively, -0.60 +/- 1.0 and -0.64 +/- 0.92 (p = 0.72). The final HtZ showed a significant correlation only with the initial HtZ and the target HtZ (THZ). Six patients achieved a final HtZ below -2, which in male patients correlated strongly to the initial HtZ and THZ. A strong correlation was demonstrated between final HtZ, initial HtZ, and THZ. INS-related issues did not prevent the final stature to reach the predicted target height.

Inflammation and Remodeling in Infantile, Juvenile, and Adult Allergic Sensitized Mice

Background: Airway structural changes occur early in childhood asthma, but it is unknown whether the development of airway alterations in children is similar to that of adults. We compared inflammation and remodeling parameters in allergic sensitized infantile, juvenile, and adult mice. Methods: Infantile mice (18D) were sensitized with three intraperitoneal injections (i.p.) of ovalbumin (OVA) at days 5 and 7 and challenged with OVA at days 14-16. The 18D1 group received an additional challenge at days 9-11. The juvenile mice (40D) received challenges at days 22-24 and 36-38. Adult mice (100D) were sensitized at days 60-62 and received three inhalations at days 77-79 and 96-98. Animals were submitted to whole body plethysmography. Airway eosinophils, CD3+ T-lymphocytes, IL-5+ cells, mucus content, collagen and reticular fibers density, and smooth muscle thickness were quantified. Results: All sensitized animals presented with airway hyperresponsiveness, without differences in eosinophil cell density The density of CD3+ T-cells was higher in the 100D and 1801 groups than in the 18D and 40D groups. Infantile sensitized groups demonstrated increased interleukin-5 expression in the airways. Infantile mice demonstrated more mucus in the bronchiolar epithelium than the 40D and 100D mice. The 18D animals demonstrated less collagen than the 18D1 group. Juvenile and adult mice had increased airway smooth muscle thickness when compared to age-matched controls, but no differences were observed in the infantile groups. Conclusion: We have shown that infantile mice develop inflammatory and structural alterations in the airways that are partially different from those developed in older animals.

Further delineation of the 15q13 microdeletion and duplication syndromes: a clinical spectrum varying from non-pathogenic to a severe outcome

Background: Recurrent 15q13.3 microdeletions were recently identified with identical proximal (BP4) and distal (BP5) breakpoints and associated with mild to moderate mental retardation and epilepsy. Methods: To assess further the clinical implications of this novel 15q13.3 microdeletion syndrome, 18 new probands with a deletion were molecularly and clinically characterised. In addition, we evaluated the characteristics of a family with a more proximal deletion between BP3 and BP4. Finally, four patients with a duplication in the BP3-BP4-BP5 region were included in this study to ascertain the clinical significance of duplications in this region. Results: The 15q13.3 microdeletion in our series was associated with a highly variable intra-and inter-familial phenotype. At least 11 of the 18 deletions identified were inherited. Moreover, 7 of 10 siblings from four different families also had this deletion: one had a mild developmental delay, four had only learning problems during childhood, but functioned well in daily life as adults, whereas the other two had no learning problems at all. In contrast to previous findings, seizures were not a common feature in our series (only 2 of 17 living probands). Three patients with deletions had cardiac defects and deletion of the KLF13 gene, located in the critical region, may contribute to these abnormalities. The limited data from the single family with the more proximal BP3-BP4 deletion suggest this deletion may have little clinical significance. Patients with duplications of the BP3-BP4-BP5 region did not share a recognisable phenotype, but psychiatric disease was noted in 2 of 4 patients. Conclusions: Overall, our findings broaden the phenotypic spectrum associated with 15q13.3 deletions and suggest that, in some individuals, deletion of 15q13.3 is not sufficient to cause disease. The existence of microdeletion syndromes, associated with an unpredictable and variable phenotypic outcome, will pose the clinician with diagnostic difficulties and challenge the commonly used paradigm in the diagnostic setting that aberrations inherited from a phenotypically normal parent are usually without clinical consequences.

Early onset of primary hypogonadism revealed by serum anti-Mullerian hormone determination during infancy and childhood in trisomy 21

Male patients with an extra sex chromosome or autosome are expected to present primary hypogonadism at puberty owing to meiotic germ-cell failure. Scarce information is available on trisomy 21, a frequent autosomal aneuploidy. Our objective was to assess whether trisomy 21 presents with pubertal-onset, germ-cell specific, primary hypogonadism in males, or whether the hypogonadism is established earlier and affects other testicular cell populations. We assessed the functional status of the pituitary-testicular axis, especially Sertoli cell function, in 117 boys with trisomy 21 (ages: 2 months-20 year). To compare with an adequate control population, we established reference levels for serum anti-Mullerian hormone (AMH) in 421 normal males, from birth to adulthood, using a recently developed ultrasensitive assay. In trisomy 21, AMH was lower than normal, indicating Sertoli cell dysfunction, from early infancy, independently of the existence of cryptorchidism. The overall prevalence rate of AMH below the 3rd percentile was 64.3% in infants with trisomy 21. Follicle-stimulating hormone was elevated in patients <6 months and after pubertal onset. Testosterone was within the normal range, but luteinizing hormone was elevated in most patients <6 months and after pubertal onset, indicating a mild Leydig cell dysfunction. We conclude that in trisomy 21, primary hypogonadism involves a combined dysfunction of Sertoli and Leydig cells, which can be observed independently of cryptorchidism soon after birth, thus prompting the search for new hypotheses to explain the pathophysiology of gonadal dysfunction in autosomal trisomy.

Autoimmune hepatitis and juvenile systemic lupus erythematosus

Juvenile systemic lupus erythematosus (JSLE) and autoimmune hepatitis (AIH) are both autoimmune disorders that are rare in children and have a widespread clinical manifestation. A few case reports have shown a JSLE-AIH associated disorder. To our knowledge, this is the first study that simultaneously evaluated the prevalence of JSLE-AIH in a large JLSE and AIH population in groups of Hepatology and Rheumatology of a tertiary Paediatric University Hospital. In a 24-year period, 228 patients were diagnosed with JSLE (ACR criteria). In the same period, 252 patients were diagnosed with AIH according to the International Autoimmune Hepatitis Group. In this article, we present the demographic data, clinical features, laboratory exams and treatment of four children with both the diseases. The prevalence was 1.8% in JSLE population and was 1.6% in AIH population. The current median age was 15.5 years and three were females. In three of them, the diagnosis of AIH preceded JSLE. All of them had increased liver enzymes with a characteristic liver biopsy of AIH and responded to the combination of prednisone, azathioprine and antimalarial drugs. In conclusion, the presence of AIH-JSLE associated disorder was rarely observed. The liver biopsy could be necessary in patients with JLSE with a persistent increase of liver enzymes.

Executive dysfunction in children and adolescents with temporal lobe epilepsy: Is the Wisconsin Card Sorting Test enough?

The Wisconsin Card Sorting Test (WCST) is the gold standard in the evaluation of executive dysfunction (ED) in patients with temporal lobe epilepsy (TLE). We evaluated 35 children with TLE and 25 healthy controls with the WCST and with a more comprehensive battery. Among the children with TLE, 77.14% showed impairment on the WCST. On other tests (Wechsler Intelligence Scale for Children-Digit Forward, Matching Familiar Figures Test, Trail Making Test, Word Fluency, Finger Windows, and Number-Letter Memory), impairment was demonstrated in 94.29%. The authors concluded that the WCST is a good paradigm to measure executive impairment in children with TLE: however, it may be not enough. Evaluation performed only with the WCST not only underestimated the number of patients with ED, but also missed relevant information regarding the type of ED. (C) 2009 Elsevier Inc.

Cisplatin and Etoposide in Childhood Germ Cell Tumor: Brazilian Pediatric Oncology Society Protocol GCT-91

Purpose In 1988, we formed a consortium of Brazilian institutions to develop uniform standards for the diagnostic assessment and multidisciplinary treatment of children and adolescents with germ cell tumors. We also implemented the first childhood Brazilian germ cell tumor protocol, GCT-91, evaluating two-agent chemotherapy with cisplatin and etoposide (PE). We now report on the clinical characteristics and survival of children and adolescents with germ cell tumors treated on this protocol. Patients and Methods From May 1991 to April 2000, 115 patients (106 assessable patients) were enrolled onto the Brazilian protocol with a diagnosis of germ cell tumor. Results Patients were treated with surgery only (n = 35) and chemotherapy (n = 71). Important prognostic factors included stage (P = .025), surgical procedure at diagnosis according to resectability (P = .032), and abnormal lactate dehydrogenase value at diagnosis (P = .001). Conclusion The improvement in survival by the introduction of a standard protocol is an important achievement. This is of particular importance for smaller institutions with previous limited experience in the treatment of childhood germ cell tumors. In addition, the results of a two-agent regimen with PE were favorable (5-year overall survival rate is 83.3% for patients in the high-risk group [n = 36] who received PE v 58.8% for patients in the high-risk patients group who received PE plus ifosfamide, vinblastine, and bleomycin [n = 17; P = .017]). Thus for selected patients, complex three-agent regimens may not be necessary to achieve long-term survival, even for some patients with advanced disease.

SPINAL POSTURAL ALIGNMENT VARIANCE ACCORDING TO SEX AND AGE IN 7-AND 8-YEAR-OLD CHILDREN

Purpose: Children`s postural alignment undergoes many adjustments due to the changes in body proportions during the stages of growth. The objective of this study was to quantitatively characterize and analyze spinal postural standards in 7- and 8-year-old children to verify which of the differences found were correlated to age and sex. Methods: Two hundred thirty public school students (Amparo, Sao Paulo, Brazil) aged 7 to 8 years were divided into groups according to postural alignment, which were further subdivided by sex and age, for comparison. Digital photos of upright Subjects were analyzed to evaluate posture. Lumbar and thoracic curvature, pelvic inclination, head posture, and lateral spine deviation were measured using CorelDraw (Ottawa, Canada) software guidelines and bone landmarks. Descriptive statistics and analysis of variance data analysis were utilized to verify differences among the groups. This was a cross-sectional, descriptive study. Results: Mean values for the variables analyzed were calculated. For lumbar lordosis, 7-year-old boys showed 38.49 degrees +/- 15.32 degrees in comparison to all other groups (42.29 degrees +/- 7.13 degrees). For thoracic kyphosis, the 7-year-old children presented 28.07 degrees +/- 7.73 degrees. and the 8-year-olds 30.32 degrees +/- 7.73 degrees. Pelvic inclination presented a mean value of 15.82 degrees +/- 5.46 degrees and single lateral spine deviation mean value of 3.48 degrees +/- 2.12 degrees. Conclusion: For the sample studied, differences based on sex and age were found for some of the body segments analyzed. The values found in this study may contribute to improved physiotherapeutic treatment when associated with other aspects of the clinical assessment and symptomatology.

Psoriasis in childhood and adolescence

Psoriasis is a chronic, immunologically mediated, recurrent and universal inflammatory disorder. Approximately one third of adults refer onset before 16 years of age. The sooner the onset, the worse is the prognosis. In children, lesions may be physically disfiguring, leading to psychological impairment and evident loss of quality of life. Systemic therapy used in psoriasis, as well as phototherapy, has limited use in children due to accumulative effects of drugs, low acceptance, and risk of teratogenicity. In this section, we discuss the main clinical aspects of psoriasis in childhood and adolescence. differential diagnosis, therapeutic options, and prognosis.

Abnormal corpus callosum myelination in pediatric bipolar patients

Background: Decreased signal intensity in the corpus callosum, reported in adult bipolar disorder patients, has been regarded as an indicator of abnormalities in myelination. Here we compared the callosal signal intensity of children and adolescents with bipolar disorder to that of matched healthy subjects, to investigate the hypothesis that callosal myelination is abnormal in pediatric bipolar patients. Methods: Children and adolescents with DSM-lV bipolar disorder (n=16, mean age +/- S.D. = 15.5 +/- 3.4 y) and matched healthy comparison subjects (n=21, mean age +/- S.D.=16.9 3.8 y) underwent a 1.5 T MRI brain scan. Corpus callosuin signal intensity was measured using an Apple Power Mac G4 running NIH Image 1.62 software. Results: Bipolar children and adolescents had significantly lower corpus callosum signal intensity for all callosal sub-regions (genu, anterior body, posterior body, isthmus and splenium) compared to healthy subjects (ANCOVA, all p < 0.05, age and gender as covariates). Limitations: Relatively small sample size. Conclusions: Abnormalities in corpus callosum, probably due to altered myelination during neurodevelopment, may play a role in the pathophysiology of bipolar disorder among children and adolescents.

Sudden unexpected death in an adolescent with epilepsy: All roads lead to the heart?

The incidence of sudden unexpected death in epilepsy (SUDEP) has been estimated from 0.5-1.4/1,000 person-years in people with treated epilepsy, and 9/1,000 person-years in candidates for epilepsy surgery. Potential risk factors for SUDEP include: age, early onset of epilepsy, duration of epilepsy, uncontrolled seizures, seizure type and winter temperatures. The arrythmogenic side-effect of antiepileptic drugs and seizures may increase the risk of SUDEP. In this report, we describe a patient with prolonged post-ictal tachycardia in EEG video recordings with a typical case of SUDEP: a 16-year-old boy with medically intractable complex partial seizures. Magnetic resonance imaging revealed left mesial temporal sclerosis. During non-invasive video-EEG monitoring, the patient presented a post-ictal heart rate increased for five hours. Two months after video-EEG, he died from SUDEP during a tonic-clonic secondary generalized seizure. The possibility of cardiac involvement in the pathogenesis of SUDEP has been suggested by many studies. Evaluation of this patient with EEG-video monitoring, including measurement of heart rate, contributed to an identification of ictal tachycardia that may have played a role in the SUDEP. Premature mortality seems to be increased in patients with epilepsy, and cardiac abnormalities may be a possible cause of SUDEP. (Cardiol J 2011; 18, 2: 194-196)

Pediatric epilepsy surgery and sudden unexpected death epilepsy: the contribution of a Brazilian epilepsy surgery program

Individuals with epilepsy are at higher risk of death than those from the general population, and sudden unexpected death in epilepsy (SUDEP) is the most important direct epilepsy-related cause of death. Epilepsies in the pediatric group are more frequently associated with known potentially risk factors for SUDEP, and a treatment resulting in an improved seizure control may also decrease mortality. The aim of this study is to identify the incidence of SUDEP in a group of operated-on children and adolescents. We analyzed 267 patients up to 18 years old, with medically intractable epilepsy submitted to surgery. We considered the age at surgery, the seizure type, the pathological findings, and the seizure outcome. Data were prospectively collected, according to the protocols of our institution`s ethics committee. The percentage of boys was 58.05. A good outcome was achieved in 72.6% of the cases and a bad outcome in 27.4%. Nine patients died during follow-up, six from clinical complications, and one from SUDEP. All patients who died during the long-term follow-up had persisted with refractory postoperative seizures. The patient who died from SUDEP died during a generalized tonic-clonic seizure. Of the patients, 72.6% had excellent postoperative outcome, and one patient died of SUDEP. All patients who died had had disabling seizures` persistence. The surgical treatment of epilepsy in children and adolescents is an efficient therapy for the medically intractable symptomatic epilepsies and also for the reduction of mortality and SUDEP risks.

In pursuit of prognostic factors in children with pilocytic astrocytomas

This study described a 23-year experience in the treatment of children with pilocytic astrocytomas (piloA) with the aim of identifying putative clinical, histopathological, and/or immunohistochemical features that could be related to the outcome of these patients. Clinical data of 31 patients under 18 years of age with piloA were obtained from 1984 to 2006. The mean age at the time of surgery was 7.8 +/- 4.2 years (1 to 17 years), and the mean follow-up was 5.7 +/- 5.4 years (1 to 20 years). The most common site of tumor formation was the cerebellum (17), followed by brainstem (4), optic chiasmatic hypothalamic region (4), cerebral hemisphere (3), cervical spinal cord (2), and optic nerve (1). Gross total resection (GTR) was achieved in 23 (74.1%), mainly in those with tumors located in the cerebellum and cerebral hemispheres (P = 0.02). The global mortality rate was 6.4%. Nine patients were reoperated. Rosenthal fibers, eosinophilic granular bodies, microvascular proliferation, and lymphocytic infiltration were observed in most cases. The mean Ki-67LI was 4.4 +/- 4.5%. In all cases, Gal-3 expression in tumor cells was observed with variable staining pattern. Aside from GTR, no other clinical, histopathological, or immunohistochemical features were found to be related to the prognosis. We postulate that strict follow-up is recommended if piloA is associated with high mitotic activity/Ki67-LI, or if GTR cannot be achieved at surgery. Tumor recurrence or progression of the residual lesion should be strictly observed. In some aspects, childhood piloA remains an enigmatic tumor.

Childhood radiation-associated atypical meningioma with novel complex rearrangements involving chromosomes 1 and 12

Meningiomas are recognized as the most common late complication following radiotherapy. However, cytogenetic studies in childhood atypical radiation-induced meningioma are sporadic, mainly because this condition generally occurs after a long latent period. In the present study we show the results of conventional and molecular cytogenetics in a 14-year-old boy with a secondary atypical meningioma. Apart from numerical changes, we found complex aberrations with the participation of chromosomes 1, 6 and 12. The invariable presence of loss of 1p was demonstrated by fluorescent in situ hybridization (FISH) analysis with probes directed to telomeric regions and by comparative genome hybridization (CGH). Previous cytogenetic studies on adult spontaneous and radiation-associated meningiomas showed loss of chromosome 22 as the most frequent change, followed by loss of the short arm of chromosome 1. To the best of our knowledge this is the first report of highly complex chromosome aberrations in the pediatric setting of meningioma.
