Twelve-Month Prevalence of and Risk Factors for Suicide Attempts in the World Health Organization World Mental Health Surveys

Objective: Although suicide is a leading cause of death worldwide, clinicians and researchers lack a data-driven method to assess the risk of suicide attempts. This study reports the results of an analysis of a large cross-national epidemiologic survey database that estimates the 12-month prevalence of suicidal behaviors, identifies risk factors for suicide attempts, and combines these factors to create a risk index for 12-month suicide attempts separately for developed and developing countries. Method: Data come from the World Health Organization (WHO) World Mental Health (WMH) Surveys (conducted 2001-2007), in which 108,705 adults from 21 countries were interviewed using the WHO Composite International Diagnostic Interview. The survey assessed suicidal behaviors and potential risk factors across multiple domains, including socio-demographic characteristics, parent psychopathology, childhood adversities, DSM-IV disorders, and history of suicidal behavior. Results: Twelve-month prevalence estimates of suicide ideation, plans, and attempts are 2.0%, 0.6%, and 0.3%, respectively, for developed countries and 2.1%, 0.7%, and 0.4%, respectively, for developing countries. Risk factors for suicidal behaviors in both developed and developing countries include female sex, younger age, lower education and income, unmarried status, unemployment, parent psychopathology, childhood adversities, and presence of diverse 12-month DSM-IV mental disorders. Combining risk factors from multiple domains produced risk indices that accurately predicted 12-month suicide attempts in both developed and developing countries (area under the receiver operating characteristic curve = 0.74-0.80). Conclusions: Suicidal behaviors occur at similar rates in both developed and developing countries. Risk indices assessing multiple domains can predict suicide attempts with fairly good accuracy and may be useful in aiding clinicians in the prediction of these behaviors.

Quality of life in elderly with dizziness

Dizziness is frequent in elderly people. Aims: To evaluate the Quality of Life (QoL) in elderly subjects with dizziness, relate it with gender and age. Material and Method: A prospective study comprising 120 elderly patients with dizziness evaluated with Brazilian versions of the Whoqol-bref and the dizziness handicap inventory (DHI). The factor analysis (FA), the Mann Whitney and Kruskal Wallis tests, and the Spearman correlation were applied to study the results. Results: The most compromised domains were the DHI physical domain and the Whoqol-bref physical and environment domains. FA resulted in 3 factors in the DHI and 5 factors in the Whoqol-bref. There was a moderate correlation (-0.596) in the total scores of both instruments. Males had a better QoL in the ""environment perception and introspectivity"" and ""health perception"" factors of the Whoqol-bref test. Females had a better QoL in the ""functionality perception"" factor of the Whoqol-bref test. There were no significant age differences. Conclusions: Elderly patients with dizziness have a worse QoL. Elderly females with dizziness have worse QoL scores in ""environment perception and introspectivity"" and ""health perception"" and better QoL in the ""functionality perception"" factor compared to elderly males.

Childhood adversities and adult psychopathology in the WHO World Mental Health Surveys

Background Although significant associations of childhood adversities with adult mental disorders are widely documented, most studies focus on single childhood adversities predicting single disorders. Aims To examine joint associations of 12 childhood adversities with first onset of 20 DSM-IV disorders in World Mental Health (WMH) Surveys in 21 countries. Method Nationally or regionally representative surveys of 51 945 adults assessed childhood adversities and lifetime DSM-IV disorders with the WHO Composite International Diagnostic Interview (CIDI). Results Childhood adversities were highly prevalent and interrelated. Childhood adversities associated with maladaptive family functioning (e.g. parental mental illness, child abuse, neglect) were the strongest predictors of disorders. Co-occurring childhood adversities associated with maladaptive family functioning had significant subadditive predictive associations and little specificity across disorders. Childhood adversities account for 29.8% of all disorders across countries. Conclusions Childhood adversities have strong associations with all classes of disorders at all life-course stages in all groups of WMH countries. Long-term associations imply the existence of as-yet undetermined mediators.

Inhibition of phospholipase A(2) in rat brain decreases the levels of total Tau protein

The microtubule-associated protein Tau promotes the assembly and stability of microtubules in neuronal cells. Six Tau isoforms are expressed in adult human brain. All six isoforms become abnormally hyperphosphorylated and form neurofibrillary tangles in Alzheimer disease (AD) brains. In AD, reduced activity of phospholipase A(2) (PLA(2)), specifically of calcium-dependent cytosolic PLA(2) (cPLA(2)) and calcium-independent intracellular PLA(2) (iPLA(2)), was reported in the cerebral cortex and hippocampus, which positively correlated with the density of neurofibrillary tangles. We previously demonstrated that treatment of cultured neurons with a dual cPLA(2) and iPLA(2) inhibitor, methyl arachidonyl fluorophosphonate (MAFP), decreased total Tau levels and increased Tau phosphorylation at Ser(214) site. The aim of this study was to conduct a preliminary investigation into the effects of in vivo infusion of MAFP into rat brain on PLA(2) activity and total Tau levels in the postmortem frontal cortex and dorsal hippocampus. PLA(2) activity was measured by radioenzymatic assay and Tau levels were determined by Western blotting using the anti-Tau 6 isoforms antibody. MAFP significantly inhibited PLA(2) activity in the frontal cortex and hippocampus. The reactivity to the antibody revealed three Tau protein bands with apparent molecular weight of close to 40, 43 and 46 kDa in both brain areas. MAFP decreased the 46 kDa band intensity in the frontal cortex, and the 43 and 46 kDa band intensities in the hippocampus. The results indicate that in vivo PLA(2) inhibition in rat brain decreases the levels of total (nonphosphorylated plus phosphorylated) Tau protein and corroborate our previous in vitro findings.

Screening for serious mental illness in the general population with the K6 screening scale: results from the WHO World Mental Health (WMH) survey initiative

Data are reported on the background and performance of the K6 screening scale for serious mental illness (SMI) in the World Health Organization (WHO) World Mental Health (WMH) surveys. The K6 is a six-item scale developed to provide a brief valid screen for Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV) SMI based on the criteria in the US ADAMHA Reorganization Act. Although methodological studies have documented good K6 validity in a number of countries, optimal scoring rules have never been proposed. Such rules are presented here based on analysis of K6 data in nationally or regionally representative WMH surveys in 14 countries (combined N = 41,770 respondents). Twelve-month prevalence of DSM-IV SMI was assessed with the fully-structured WHO Composite International Diagnostic Interview. Nested logistic regression analysis was used to generate estimates of the predicted probability of SMI for each respondent from K6 scores, taking into consideration the possibility of variable concordance as a function of respondent age, gender, education, and country. Concordance, assessed by calculating the area under the receiver operating characteristic curve, was generally substantial (median 0.83; range 0.76-0.89; inter-quartile range 0.81-0.85). Based on this result, optimal scaling rules are presented for use by investigators working with the K6 scale in the countries studied. Copyright (c) 2010 John Wiley & Sons, Ltd.

Bone mineral density analysis in patients with primary hyperparathyroidism associated with multiple endocrine neoplasia type 1 after total parathyroidectomy

P>Objective Limited data have been reported on the effect of parathyroidectomy (PTx) on bone mineral density (BMD) in the setting of patients with hyperparathyroidism (HPT) associated with multiple endocrine neoplasia type 1 (MEN1). This study investigates the impact of total PTx on BMD in patients with HPT/MEN1. Design and patients A case series study was performed in a tertiary academic hospital. A total of 16 HPT/MEN1 patients from six families harbouring MEN1 germline mutations were subjected to total PTx followed by parathyroid auto-implant in the forearm. Measurements Bone mineral density values were assessed using dual-energy X-ray absorptiometry. Results Before PTx, reduced BMD (Z-score <-2 center dot 0) was highly prevalent in the proximal one-third of the distal radius (1/3 DR) (50%), lumbar spine (LS) (43 center dot 7%), ultradistal radius (UDR) (43 center dot 7%), femoral neck (FN) (25%) and total femur (TF) (18 center dot 7%) in the patients. Fifteen months after PTx, we observed a BMD improvement in the LS (from 0 center dot 843 to 0 center dot 909 g/cm2; +8 center dot 4%, P = 0 center dot 001), FN (from 0 center dot 745 to 0 center dot 798 g/cm2; +7 center dot 7%, P = 0 center dot 0001) and TF (from 0 center dot 818 to 0 center dot 874 g/cm2; +6 center dot 9%, P < 0 center dot 0001). No significant change was noticed in the 1/3 DR and UDR after PTx. Conclusions This data confirmed BMD recovery in the LS and FN after PTx in HPT/MEN1 patients. We also documented a significant BMD increase in the TF and no change in both the 1/3 DR and UDR BMD after PTx. Our data suggest that LS and proximal femur are the most informative sites to evaluate the short-term BMD outcome after PTx in HPT/MEN1 subjects.

AGE DIFFERENCES IN THE PREVALENCE AND CO-MORBIDITY OF DSM-IV MAJOR DEPRESSIVE EPISODES: RESULTS FROM THE WHO WORLD MENTAL HEALTH SURVEY INITIATIVE

Background: Although depression appears to decrease in late life, this could be due to misattribution of depressive symptoms to physical disorders that increase in late we. Methods: We investigated this issue by studying age differences in co-morbidity of DSM-IV major depressive episodes (MDE) with chronic physical conditions in the WHO World Mental Health (WMH) surveys, a series of community epidemiological surveys of respondents in 10 developed countries (n = 52,485) and 8 developing countries (n = 37,265). MDE and other mental disorders were assessed with the Composite International Diagnostic Interview (CIDI). Organic exclusion rules were not used to avoid inappropriate exclusion of cases with physical co-morbidity. Physical conditions were assessed with a standard chronic conditions checklist. Results: Twelve-month DSM-IV/CIDI MDE was significantly less prevalent among respondents ages 65+ than younger respondents in developed but not developing countries. Prevalence of co-morbid mental disorders generally either decreased or remained stable with age, while co-morbidity of MDE with mental disorders generally increased with age. Prevalence of physical conditions, in comparison, generally increased with age, while co-morbidity of MDE with physical conditions generally decreased with age. Depression treatment was lowest among the elderly in developed and developing countries. Conclusions: The weakening associations between MDE and physical conditions with increasing age argue against the suggestion that the low estimated prevalence of MDE among the elderly is due to increased confounding with physical disorders. Future study is needed to investigate processes that might lead to a decreasing impact of physical illness on depression among the elderly. Depression and Anxiety 27:351-364, 2010.

Treatment of suicidal people around the world

Background Suicide is a leading cause of death worldwide; however, little information is available about the treatment of suicidal people, or about barriers to treatment. Aims To examine the receipt of mental health treatment and barriers to care among suicidal people around the world. Method Twenty-one nationally representative samples worldwide (n=55 302; age 18 years and over) from the World Health Organization`s World Mental Health Surveys were interviewed regarding past-year suicidal behaviour and past-year healthcare use. Suicidal respondents who had not used services in the past year were asked why they had not sought care. Results Two-fifths of the suicidal respondents had received treatment (from 17% in low-income countries to 56% in high-income countries), mostly from a general medical practitioner (22%), psychiatrist (15%) or non-psychiatrist (15%). Those who had actually attempted suicide were more likely to receive care. Low perceived need was the most important reason for not seeking help (58%), followed by attitudinal barriers such as the wish to handle the problem alone (40%) and structural barriers such as financial concerns (15%). Only 7% of respondents endorsed stigma as a reason for not seeking treatment. Conclusions Most people with suicide ideation, plans and attempts receive no treatment. This is a consistent and pervasive finding, especially in low-income countries. Improving the receipt of treatment worldwide will have to take into account culture-specific factors that may influence the process of help-seeking.

MLPA analysis in 30 Sotos syndrome patients revealed one total NSD1 deletion and two partial deletions not previously reported

Sotos syndrome (MIM #117550) is an autosomal dominant condition characterized by pre and postnatal overgrowth, macrocephaly and typical facial gestalt with frontal bossing, hypertelorism, antimongoloid slant of the palpebral fissures, prominent jaw and high and narrow palate. This syndrome is also frequently associated with brain, cardiovascular, and urinary anomalies and is occasionally accompanied by malignant lesions such as Wilms turnout and hepatocarcinoma. The syndrome is known to be caused by mutations or deletions of the NSD1 gene. To detect both 5q35 microdeletions and partial NSD1 gene deletions we screened 30 Brazilian patients with clinical diagnosis of Sotos syndrome by multiplex ligation dependent probe amplification. We identified one patient with a total deletion of NSD1 and neighbouring FGFR4, other with missing NSD1 exons 13-14 and another with a deletion involving FGFR4 and spanning up to NSD1 exon 17. All deletions were de novo. The two NSD1 partial deletions have not been previously reported. The clinical features of the three patients included a typical facial gestalt with frontal bossing, prominent jaw and high anterior hairline; macrocephaly, dolichocephaly, large hands; neonatal hypotonia and jaundice. All presented normal growth at birth but postnatal overgrowth. Two patients with NSD1 and FGFR4 gene deletions presented congenital heart anomalies. (C) 2009 Elsevier Masson SAS.

ISOKINETIC EVALUATION OF PATIENTS SUBMITTED TO TOTAL KNEE ARTHROPLASTY

Objective: In total knee arthroplasty, the minimally-invasive approach has been claimed to enable earlier rehabilitation because it spares the femoral quadriceps muscle. To check the influence of preserving the extensor apparatus during surgery, the strength of knee extension and flexion muscles was evaluated in patients submitted to total knee arthroplasty with different approaches. Materials and Methods: The values of maximum torque and total work obtained by isokinetic dynamometry six months after surgery were compared for the Minimally invasive surgery group constituted of 12 individuals submitted to total knee arthroplasty by the minimally invasive surgical approach and the Control group, constituted of eight patients submitted to total knee arthroplasty by the transquadricipital approach, between January 2005 and July 2006. Results: Statistical analysis of the absolute values for maximum torque and total work adjusted for body weights did not show differences between both groups. Conclusion: There was no difference in the extension and flexion strength of the knee muscles six months after surgery.

One-Stage Revision of Infected Total Hip Arthroplasty with Bone Graft

There are many different opinions in the literature regarding the best procedure for revision of infected hip arthroplasty and hence in achieving long-term stabilization of a new implant. Thirty-two patients with 32 loose and infected total hip arthroplasties underwent revision with a bone graft in a 1-stage procedure. The bone graft was used in the acetabulum and femure in 25 patients, in the acetabulum alone in 4 patients and in the femur alone in 3 patients. A metal mesh was necessary in 15 patients to contain the morselized bone graft. At the time of surgical revision, 9 patients had a draining sinus, 6 had a closed sinus, and 17 had never had sinuses in the surgical wound. Antibiotic therapy was administered intravenously and orally for 6 months. Mean follow-up was 103 months (range, 63-183 months), and infection recurred in 2 (6.2%) cases. Further studies are necessary, and continuation of this method is justified.

Illness duration and total brain gray matter in bipolar disorder: Evidence for neurodegeneration?

Previous studies have suggested that bipolar disorder (BD) is associated with alterations in neuronal plasticity, but the effects of the progression of illness on brain anatomy have been poorly investigated. We studied the correlation between length of illness, age, age at onset, and the number of previous episodes and total brain, total gray, and total white matter volumes in BD, unipolar (UP) and healthy control (HC) subjects. Thirty-six BD, 31 UP and 55 HCs underwent a 1.5 T brain magnetic resonance imaging scan, and gray and white matter volumes were manually traced blinded to the subjects` diagnosis. Partial correlation analysis showed that length of illness was inversely correlated with total gray matter volume after adjusting for total intracranial volume in BD (r(p)=-0.51; p=0.003) but not in UP subjects (r(p)=-0.23; p=0.21). Age at illness onset and the number of previous episodes were not significantly correlated with gray matter volumes in BD or UP subjects. No significant correlation with total white matter volume was observed. These results suggest that the progression of illness may be associated with abnormal cellular plasticity. Prospective longitudinal studies are necessary to elucidate the long-term effects of illness progression on brain structure in major mood disorders. (C) 2008 Published by Elsevier B.V.

Is Full Postpleurodesis Lung Expansion a Determinant of a Successful Outcome After Talc Pleurodesis?

Study objectives: To analyze and compare radiologic lung expansion after tale pleurodesis performed either by videothoracoscopy or chest tube and correlate it with clinical outcome. Secondary end points evaluated were its follows: clinical efficacy; quality of life; safety; and survival. Methods: Prospective randomized study that included 60 patients (45 women, 15 men; mean age, 55.2 years) with recurrent malignant pleural effusion between January, 2005 and January 2008. They were randomized into the following two groups: video-assisted thoracic surgery (VATS) talc poudrage; and tale slurry (TS) administered through a chest tube. Lung expansion was evaluated through chest CT scans obtained 0, 1, 3 and 6 months after pleurodesis. Complications, drainage time, hospital stay,and quality of life (Medical Outcomes Study 36-item short form and World Health Organization quality-of-life questionnaires) were also analyzed. Results: There were no significant differences in preprocedure clinical and pathologic variables between groups. The immediate total (ie, > 90%) lung expansion was observed in 27 patients (45%) and wits more frequent in the VATS group (60% vs 30%, respectively; p = 0.027). During follow-up, 71% of the patients showed unaltered or improved lung expansion and 9 patients (15%) needed new pleural procedures (VATS group, 5 recurrences; TS group, 4 recurrences; p = 0.999). No differences, were found between groups regarding quality of life, complications, drainage time, hospital stay, and survival. Immediate lung expansion (lid not correlate with radiologic recurrence, clinical recurrence, or complications (p = 0.60, 0.15, and 0.20, respectively). Conclusion: Immediate partial lung expansion was a frequent finding and was more frequent after TS. Nonetheless, no correlation between immediate lung expansion and clinical outcome was found in this study. (CHEST 2009; 136:361-368)

Sonographic Evaluation of the Abductor Mechanism After Total Hip Arthroplasty

Objective. The purpose of this series was to determine the frequency of abductor mechanism avulsion by sonography after total hip arthroplasty with the Hardinge approach (J Bone Joint Surg Br 1982; 64:17-19) and its relationship to the presence of insufficiency of this musculature in the postoperative period. Methods. Thirty-four consecutive patients were prospectively accessed in the postoperative period of hip arthroplasty by the Trendelenburg test, hip sonography, and abductor muscle electromyography. In patients who were found to have clinical insufficiency of the abductor musculature, we also measured the femoral offset in the preoperative and postoperative radiographs. Hip sonography was performed by an experienced musculoskeletal radiologist blinded to the other tests, and the tendons of the gluteus medius and gluteus minimus were visualized on longitudinal and transverse sections with a 7- to 10-MHz linear transducer. Results. Eight patients presented clinical insufficiency of the abductor musculature as detected by the Trendelenburg test. Four of these 8 patients with abductor insufficiency presented tendinous avulsion detected by sonography. One of the 4 patients with abductor insufficiency and normal sonographic findings had a decrease in the femoral offset caused by the arthroplasty itself. Two patients presented electromyographic changes of the abductor musculature, with no tendinous avulsion detected by sonography and no abductor insufficiency. Conclusions. We concluded that in patients undergoing total hip arthroplasty by the Hardinge approach in whom insufficiency of the abductor musculature develops, sonography is an interesting method of investigation because it identified the cause of this problem in most of our patients.

Multiple cranial burr holes as an alternative treatment for total scalp avulsion

Total scalp avulsion is a devastating injury in clinical practice. It often occurs in female adults, being rare in children. The standard treatment for scalp avulsion is microsurgical replantation, when feasible. Coverage becomes a major problem when replantation fails or is contraindicated, resulting in significant morbidity and requiring multiple procedures. In this article, in addition to reviewing the literature, we report a historical method for obtaining skin coverage after failure of replantation. The authors report a case of a 10-year-old girl who had her scalp totally avulsed by an agricultural machine, including her right auricle. Microsurgery scalp replantation was attempted immediately after fluid resuscitation. The surgery failed probably due to the long time interval between trauma and surgery, which resulted in total ischemic time of 11 h and consequently made vascular microanastomosis impracticable. Multiple trephination of the calvarium was performed in order to expose the diploe. After 4 weeks, granulation tissue from the holes began to cover the defect, allowing the formation of a vascular bed suitable for skin grafting. Total scalp avulsion in children is seldom reported in the literature. Therefore, its management is both difficult and challenging. The exposure of the diploe with multiple burr holes is a safe and effective method for treating this injury. It may be considered, along with skin grafting, a good therapeutic alternative to be used when microsurgical replantation fails or is not feasible.
