The validity and reliability of preschool age psychiatric assessment (PAPA) in Turkish population

INTRODUCTION

The Preschool Age Psychiatric Assessment (PAPA) was developed in response to the need for a standard and reliable tool for assessing preschool-age psychiatric disorders. The aim of this study was to translate PAPA into the Turkish language and evaluate the validity and reliability.

METHODS

The researchers translated the original PAPA to Turkish, and the Turkish version of PAPA was translated back into its original language by professional translators. After the psychiatric assessment of the 300 patients by child psychiatrist, the PAPA interview was implemented with the parents. The sociodemographic data form and the PAPA short forms were filled out by the clinician conducting the interview. The Child Behavior Checklist for Ages 1.5-5 (CBCL/1½-5) was completed by parents.

RESULTS

The rate of detecting true positives and true negatives in all subscales when comparing PAPA with CBCL in children under 60 months ranged from 65% to 88%. The AUC values were above 50%, ranging from 0.56 to 0.72, indicating that PAPA performed reasonably well in detecting true positives and true negatives compared to CBCL. According to DC: 0-5, it was found that the adjustment was good for total psychopathologies, separation anxiety disorder, social anxiety disorder, and depression (κ = 0.67-0.79), and excellent for GAD and PTSD (κ = 0.81-1.00) CONCLUSION: The validity and reliability obtained from this study are valuable in our country for the objective identification of preschool children showing problematic symptom levels and for distinguishing them from children showing typical characteristics.

A Psychometric Study of the Perinatal Assessment of Maternal Affectivity (PAMA) for the Screening of Perinatal Affective Disorders in Mothers

Recently, empirical evidence from perinatal studies has led researchers to pay more attention to fathers. The need to evaluate male suffering led at first to using the same screening tools developed for mothers. However, these instruments present validity concerns with fathers, and today the need to assume a gender-based perspective is clear. The Perinatal Assessment of Paternal Affectivity (PAPA) is a self-reported questionnaire for the screening of a variety of psychological and behavioral dimensions related to affectivity as experienced by fathers during the perinatal period. In the present study, the psychometric properties of the maternal version of the scale (Perinatal Assessment of Maternal Affectivity; PAMA) were examined. The study, based on 225 mothers and their partners (n = 215), used a cross-sectional design with a single assessment at the third trimester of pregnancy. Results indicated a one-factor structure for a seven-item version of the PAMA, which showed adequate internal consistency reliability and was associated in the expected direction with other clinically relevant variables (depression, psychological distress, perceived stress and dyadic adjustment). The findings suggest the usefulness of developing gender sensitive screening tools for the detection of perinatal affective disorders.

Genetic overview of postaxial polydactyly: Updated classification

Polydactyly or polydactylism, also known as a hyperdactyly, is a congenital limb defect with various morphologic phenotypes. Apart from physical and functional impairments, the presence of polydactyly is an indication of an underlying syndrome in the newborn. Usually, it follows as an autosomal dominant/recessive inheritance pattern with defects in the limb development's anteroposterior patterning. Although mutations in several genes have been associated with polydactyly; however, the exact underlying cause, pathways, and disease mechanisms are still unexplored, thus making it of multi-factorial origin. Polydactyly is divided into three subtypes; radial, ulnar, and central polydactyly. So far, 11 loci (PAPA1-PAPA11) and seven human genes have been reported to cause non-syndromic postaxial polydactyly in humans, including the ZNF141, GLI3, IQCE, GLI1, FAM92A1, KIAA0825, and DACH1. In this review, we discuss emerging evidences of clinical and molecular characterization of polydactyly types in term of the involvement of newly associated genes and loci for non-syndromic postaxial polydactyly, and how these might impact our understanding of the genetic mechanisms and molecular etiology involved in the cause of polydactyly.

Longitudinal relations between impaired executive function and symptoms of psychiatric disorders in childhood

BACKGROUND

Malfunctioning of executive functions correlates with psychopathology in children. However, the directionality, the extent to which the relation varies for various disorders, and whether prospective relations afford causal interpretations are not known.

METHODS

A community sample of Norwegian children (n = 874) was studied biennially from the age of 6 to 14 years. Executive functions were assessed using the Behavior Rating Inventory of Executive Function Teacher-report and symptoms of psychopathology were assessed using the Preschool Age Psychiatric Assessment (age 6; parents) and Child and Adolescent Psychiatric Assessment (ages 8-14; children and parents). Prospective reciprocal relations were examined using a random intercept cross-lagged panel model that adjusts for all unobserved time-invariant confounders.

RESULTS

Even when time-invariant confounders were accounted for, reduced executive functions predicted increased symptoms of depressive disorders, anxiety disorders, attention-deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD) 2 years later, even when previous changes in these symptoms were adjusted for. The level of prediction (B = .83, 95% CI [.37, 1.3]) was not different for different disorders or ages. Conversely, reduced executive functions were predicted by increased symptoms of all disorders (B = .01, 95% CI [.01, .02]).

CONCLUSIONS

Reduced executive functioning may be involved in the etiology of depression, anxiety, ADHD, and ODD/CD to an equal extent. Moreover, increased depression, anxiety, ADHD, and ODD/CD may negatively impact executive functioning.

PSTPIP1-associated myeloid-related proteinaemia inflammatory (PAMI) syndrome; a case presenting as a perinatal event with early central nervous system involvement?

BACKGROUND

We report a three-year-old girl with a potentially unique phenotype of perinatal onset and neurovascular features who was found to have PAMI syndrome. We also compare her case to those previously reported and review the differences between the PSTPIP1-associated inflammatory diseases (PAID) phenotypes and genotypes.

CASE PRESENTATION

The patient was found to have a heterozygous pathogenic variant in PSTPIP1 (c.748G > A p.E250K). This variant was shown to be absent in both parents and therefore de novo in the patient. A literature review was carried out through multiple databases using the terms PSTPIP1, PAID, PAPA syndrome and PAMI syndrome. This information was collected and used to form comparisons between the current literature and our reported case.

CONCLUSIONS

Our case contributes to the literature on PAMI syndrome whilst providing an example of a potentially unique clinical phenotype, giving insight into the pre-symptomatic phase of the condition. We highlight the importance of considering PAMI syndrome in the differential for early onset unexplained inflammation. In addition, we explore the possibility that perinatal neurovascular events could be an early feature of PAMI syndrome.

Case Report: PsAPSASH syndrome: an alternative phenotype of syndromic hidradenitis suppurativa treated with the IL-17A inhibitor secukinumab

Syndromic hidradenitis suppurativa (HS) is a form of symptom constellations, which differs from the familial and genetic form and comprises predominantly osteoarticular manifestations. Many forms include pyoderma gangrenosum and acne (PASH), pyogenic arthritis (PAPASH), spondyloarthritis (PASS) and psoriatic arthritis (PsAPASH) and are categorized in the autoinflammatory syndromes. Anti-TNF-α and anti-IL-1a blockade are between the therapeutic approaches that improve skin symptoms and prevent permanent osteoarticular damage. This case report refers to the successful treatment of a mixed phenotype of the aforementioned symptoms using the IL-17A inhibitor secukinumab after initial treatment with adalimumab. The therapy improved both cutaneous and reported osteoarticular symptoms. Different approaches for these recalcitrant HS syndromes are essential in order to achieve long-term remission for those patients.

Psychometric properties of the Persian version of preschool age psychiatric assessment (PAPA) for attention-deficit/hyperactivity disorder: Based on DSM-5

Childhood and adolescence psychiatric disorders affect subsequent stages; early diagnosis of these disorders, such as attention-deficit/hyperactivity disorder (ADHD), is necessary. There is no reliable and valid diagnostic interview for ADHD in Asian Persian or Farsi speaking countries. The DSM 5-based version of the interview was sent to the 14 child and adolescent and general psychiatrists to ensure the validity of the ADHD section of the PAPA interview through an online website. Out of 59 health centers, 15 centers were selected via systematic random sampling. Three hundred children participated in the study. ADHD questions of the PAPA had the power to differentiate, with a sensitivity of 0.92, a specificity of 0.01. It had positive diagnostic value = 95.83 %, negative diagnostic value = 98.91 %, negative correlation ratio = 0.12, overall diagnostic accuracy = 98.67 % and diagnostic chance ratio = 2085.35. ADHD questions of the PAPA diagnostic interview can diagnose ADHD in preschool as a reliable tool based on DSM-5.

Novel GLI3 Mutations in Chinese Patients with Non-syndromic Post-axial Polydactyly

BACKGROUND

Polydactyly, characterized by supernumerary digits in the upper or lower extremities, is the most common congenital digital abnormalities. It derives from the defective patterning of anteroposterior axis of the developing limb, with various etiology and clinical heterogeneity. The patients with post-axial polydactyly type A (PAPA) have the typical symptom of a well-formed supernumerary digit outside the fifth digit.

OBJECTIVE

The aim of present study was to identify the causative mutations of two unrelated Han Chinese patients with non-syndromic PAPA.

METHODS

Two unrelated Han Chinese patients and 100 ethnicity-matched, unrelated normal controls were recruited for this study. BGISEQ-500 exome sequencing was performed in the two patients, followed by validation in the patients and 100 controls by using Sanger sequencing.

RESULTS

Two mutations in the GLI family zinc finger 3 gene (GLI3), including a frameshift mutation c.3437_3453delTCGAGCAGCCCTGCCCC (p.L1146RfsX95) and a nonsense mutation c.3997C>T (p.Q1333X), were identified in two patients but were absent in the 100 healthy controls.

CONCLUSION

The two GLI3 mutations, p.L1146RfsX95 and p.Q1333X, may account for non-syndromic PAPA in the two patients, respectively. The findings of this study may expand the mutational spectrum of GLI3-PAPA and provide novel insights into the genetic basis of polydactyly.

A child with recurrent pyogenic arthritis with the PSTPIP1 mutation

Pyogenic arthritis, pyoderma gangrenosum, and acne syndrome is a rare disease, linked to an auto-inflammatory pathway. We report a 7-year-old boy with recurrent suppurative knee arthritis without signs of suppurative skin infection or ulcer; his younger brother had the same symptom. Genetic testing indicated the presence of proline-serine-threonine phosphatase interacting protein 1 gene mutation in both boys. Our patient’s grandfather had a history of recurrent pyoderma, and his father though a genetic carrier had no symptoms. Interestingly, our patient displayed markedly high levels of interleukin-6, while interleukin-1 and other cytokines were not elevated. These lab findings led to the treatment of pyogenic arthritis, pyoderma gangrenosum, and acne syndrome with tocilizumab. Previously reported cases of similar phenotypes of the syndrome have not presented in this fashion, nor have there been reported cases of pyogenic arthritis, pyoderma gangrenosum, and acne syndrome with a positive family history and an elevation in interleukin-6. The mutation site of proline-serine-threonine phosphatase interacting protein 1 in this incomplete pyogenic arthritis, pyoderma gangrenosum, and acne syndrome has not been reported before. It is possible that there are other pathogenic ways to trigger these auto-inflammatory disorders. Tocilizumab, which specifically targets interleukin-6, was effective in this case.

Exome sequencing revealed a novel loss-of-function variant in the GLI3 transcriptional activator 2 domain underlies nonsyndromic postaxial polydactyly

Background

Polydactyly is a common genetic limb deformity characterized by the presence of extra fingers or toes. This anomaly may occur in isolation (nonsyndromic) or as part of a syndrome. The disease is broadly divided into preaxial polydactyly (PPD; duplication of thumb), mesoaxial polydactyly (complex polydactyly), and postaxial polydactyly (PAP: duplication of the fifth finger). The extra digits may be present in one or both the limbs. Heterozygous variants in the GLI3, ZRS/SHH, and PITX1 have been associated with autosomal dominant polydactyly, while homozygous variants in the ZNF141, IQCE, GLI1, and FAM92A have been associated with autosomal recessive polydactyly. Pathogenic mutations in the GLI3 gene (glioma‐associated oncogene family zinc finger 3) have been associated with both nonsyndromic and syndromic polydactyly.

Methods

Here, we report an extended five generation kindred having 12 affected individuals exhibiting nonsyndromic postaxial polydactyly type A condition. Whole‐exome sequencing followed by variant prioritization, bioinformatic studies, Sanger validation, and segregation analysis was performed.

Results

Using exome sequencing in the three affected individuals, we identified a novel heterozygous frameshift variant (c.3567_3568insG; p.Ala1190Glyfs*57) in the transcriptional activator (TA2) domain of the GLI3 encoding gene.

Conclusion

To the best of our knowledge, the present study reports on the first familial case of nonsyndromic postaxial polydactyly due to the GLI3 variant in Pakistani population. Our study also demonstrated the important role of GLI3 in causing nonsyndromic postaxial polydactyly.

FAM92A Underlies Nonsyndromic Postaxial Polydactyly in Humans and an Abnormal Limb and Digit Skeletal Phenotype in Mice

Polydactyly is a common congenital anomaly of the hand and foot. Postaxial polydactyly (PAP) is characterized by one or more posterior or postaxial digits. In a Pakistani family with autosomal recessive nonsyndromic postaxial polydactyly type A (PAPA), we performed genomewide genotyping, linkage analysis, and exome and Sanger sequencing. Exome sequencing revealed a homozygous nonsense variant (c.478C>T, p.[Arg160*]) in the FAM92A gene within the mapped region on 8q21.13-q24.12 that segregated with the PAPA phenotype. We found that FAM92A is expressed in the developing mouse limb and E11.5 limb bud including the progress zone and the apical ectodermal ridge, where it strongly localizes at the cilia level, suggesting an important role in limb patterning. The identified variant leads to a loss of the FAM92A/Chibby1 complex that is crucial for ciliogenesis and impairs the recruitment and the colocalization of FAM92A with Chibby1 at the base of the cilia. In addition, we show that Fam92a^-/- homozygous mice also exhibit an abnormal digit morphology, including metatarsal osteomas and polysyndactyly, in addition to distinct abnormalities on the deltoid tuberosity of their humeri. In conclusion, we present a new nonsyndromic PAPA ciliopathy due to a loss-of-function variant in FAM92A. © 2018 American Society for Bone and Mineral Research.

An update on the pathogenesis of hidradenitis suppurativa: implications for therapy

INTRODUCTION

Hidradenitis suppurativa is a chronic, inflammatory disease characterized by painful nodules, abscesses, and sinuses in the intertriginous areas, with significant associated comorbidities. The pathogenesis remains unclear, although advances have been made in understanding the disease process. Management of the disease is challenging, with a wide range of treatment options available with variable clinical response. Areas covered: This review discusses the most updated studies on the complex pathogenic mechanisms of hidradenitis suppurativa and the relevant literature on the current treatment options for this condition. Expert commentary: There is increasing evidence supporting the role of Th17 cells and enhanced expression of IL-17 and IL-1β, which represent potential targets for therapy. Bacteria and biofilms are likely contributory but secondary drivers of inflammation. There is also evolving evidence to suggest the presence of systemic comorbidities associated with HS, which underlie the importance of better understanding the pathogenesis and treatment of this disease.

Pyoderma gangrenosum: a review of pathogenesis and treatment

INTRODUCTION

Pyoderma gangrenosum (PG) is a complex neutrophilic dermatosis that can occur as an idiopathic disease, in association with systemic conditions such as inflammatory bowel disease, as part of an inherited inflammatory syndrome. It can be challenging to treat, as it occurs in a wide variety of clinical settings and there is a lack of a standardized treatment approach. The main limitations to treatment have been an incomplete understanding of the pathogenesis. However, recent advances have been made in understanding the pathogenesis of this condition, and PG is now considered an autoinflammatory disease process. Areas covered: This review discusses the newest studies that further define our understanding of this disease and the relevant literature on treatment options for pyoderma gangrenosum. Expert commentary: The presence of abnormal neutrophils and T-cells lead to immune dysregulation, leading to lesions of PG. Increased levels of inflammatory mediators including IL-1β, IL-8, IL-17, and TNF-α contribute to the development of the disease but there are still several unknown factors, including the trigger for immune dysregulation and additional contributory components of the immune system. We provide our approach to the management of PG lesions, which involves a multi-faceted approach including wound care, topical therapy, and systemic medications in most cases.

Initial development of the Psychopathic Processing and Personality Assessment (PAPA) across populations

Three studies describe development of the Psychopathic Processing and Personality Assessment (PAPA). Study one outlines a literature review and Expert Delphi (n=32) to develop the initial PAPA. Study two validates the PAPA with 431 participants (121 male prisoners and 310 university students: 154 men, 156 women), also using the Levenson Self Report Psychopathy scale and a measure of cognitive schema and affect. Study three refined the PAPA, employing it with 50 male students and 40 male forensic psychiatric patients using clinical (interview) assessments of psychopathy: the Psychopathy Checklist - Screening Version and the Affect, Cognitive and Lifestyle assessment. The PAPA comprised four factors; dissocial tendencies; emotional detachment; disregard for others; and lack of sensitivity to emotion. It positively correlated with existing psychopathy measures. Variations across PAPA subscales were noted across samples when associated with clinical measures of psychopathy. Support for the validity of the PAPA was indicated across samples. Directions for research and application are outlined.

Treating inflammation by blocking interleukin-1 in humans

IL-1 is a master cytokine of local and systemic inflammation. With the availability of specific IL-1 targeting therapies, a broadening list of diseases has revealed the pathologic role of IL-1-mediated inflammation. Although IL-1, either IL-1α or IL-1β, was administered to patients in order to improve bone marrow function or increase host immune responses to cancer, these patients experienced unacceptable toxicity with fever, anorexia, myalgias, arthralgias, fatigue, gastrointestinal upset and sleep disturbances; frank hypotension occurred. Thus it was not unexpected that specific pharmacological blockade of IL-1 activity in inflammatory diseases would be beneficial. Monotherapy blocking IL-1 activity in a broad spectrum of inflammatory syndromes results in a rapid and sustained reduction in disease severity. In common conditions such as heart failure and gout arthritis, IL-1 blockade can be effective therapy. Three IL-1blockers have been approved: the IL-1 receptor antagonist, anakinra, blocks the IL-1 receptor and therefore reduces the activity of IL-1α and IL-1β. A soluble decoy receptor, rilonacept, and a neutralizing monoclonal anti-interleukin-1β antibody, canakinumab, are also approved. A monoclonal antibody directed against the IL-1 receptor and a neutralizing anti-IL-1α are in clinical trials. By specifically blocking IL-1, we have learned a great deal about the role of this cytokine in inflammation but equally important, reducing IL-1 activity has lifted the burden of disease for many patients.

Assessment of Childhood Depression

  Depression as a disorder in childhood began to be increasingly recognised in the 1970s. Epidemiologic community and clinic-based studies have characterised the prevalence, clinical course, and complications of this illness throughout childhood and adolescence into adulthood. This paper reviews two instruments for assessing depression in prepubertal children - the Dominic Interactive and The Preschool Age Psychiatric Assessment. Both instruments are useful in screening for psychiatric disorders and reliably identifying the presence of depressive symptoms in young children.
