Mother–Daughter Coping and Disordered Eating

This study explores whether the coping style of teenage girls with and without an eating disorder is similar to that of their mothers' (biological and adoptive), and whether teens with disordered eating utilize more maladaptive coping compared with those without. Eating disorder was diagnosed using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria, and the Coping Inventory for Stressful Situations was administered to distinguish the coping style of the participants. Our findings suggest that daughters coped very similarly to their mothers in either group. Contrary to previous studies, our sample of teenage girls with eating disorders as well as their mothers utilized less frequently the avoidance–distraction coping compared with the girls without eating disorders and their mothers. These findings reinforce the importance for family involvement and for simultaneous focus on intrapersonal and interpersonal maintenance factors during eating disorder treatment.

Association of Isolated Systolic,Isolated Diastolic,and Systolic‐Diastolic Masked Hypertension With Carotid Artery Intima‐Media Thickness

Masked hypertension (MH) is associated with advanced target organ damage. However, patients with MH constitute a group of individuals with heterogeneous characteristics concerning their ambulatory blood pressure (BP) status. The aim of this study was to evaluate the association of isolated systolic MH, isolated diastolic MH, and systolic/diastolic MH with carotid artery intima‐media thickness (CIMT). A total of 101 patients with MH underwent carotid artery ultrasonographic measurements. The patients were divided into three groups according to office and daytime BP values: isolated systolic MH, isolated diastolic MH, and systolic/diastolic MH. Patients with isolated systolic (n=36) (0.771 mm) and systolic/diastolic MH (n=37) (0.775 mm) had significantly (P<.05) higher CIMT values than those with isolated diastolic MH (n=28) (0.664 mm), even after adjustment for baseline characteristics and risk factors. Patients with isolated systolic and systolic/diastolic MH presented significantly higher CIMT values compared with patients with isolated diastolic MH.     

A brief assessment of object semantics in primary progressive aphasia

Background: A cross-culturally valid nonverbal assessment of semantic knowledge is needed. Accurately identifying impairment of object semantics is important for diagnosis of several disorders, including distinguishing semantic variant primary progressive aphasia (svPPA), a neurodegenerative condition characterised by progressive impairment in word comprehension, from logopenic and nonfluent agrammatic variants, which are not associated with impaired object semantics. However, current assessments require culturally specific knowledge.

Aims: We developed a cross-culturally valid short form of the Pyramids and Palm Trees Test to assess object semantic memory. We investigated its clinical utility in differentiating the semantic variant of primary progressive aphasia, from the logopenic and nonfluent agrammatic variants. Areas of atrophy associated with poor performance were identified.

Methods & Procedures: Fourteen items that rely on knowledge of objects’ defining features were selected from the original 52-item version. The full and short forms were administered to healthy individuals in the US (N = 18), Argentina (N = 20), and Greece (N = 12) and performance was compared. Seventy-eight individuals with primary progressive aphasia in the US completed the short form. Behavioural performance of the svPPA group (N = 24) was compared to other variants. Atlas-based analysis identified regions where atrophy correlated with poor performance in 39 individuals with primary progressive aphasia who had high-resolution magnetic resonance imaging (MRI) scans.

Outcomes & Results: Control performance was classified as normal on the short form significantly more often than on the full version. Across groups with primary progressive aphasia, the group with semantic variant performed significantly worse than the groups with logopenic or nonfluent agrammatic variants. Volume in left anterior and inferior temporal cortex correlated with performance.

Conclusions: The short-form Pyramids and Palm Trees Test is a clinically relevant, cross-culturally valid assessment of nonverbal object semantics. It can be used to identify semantic impairments, with poor performance associated with atrophy of the temporal lobes.     

Epstein‐Barr virus infection induces miR‐21 in terminally differentiated malignant B cells

The association of Epstein‐Barr virus (EBV) with plasmacytoid malignancies is now well established but how the virus influences microRNA expression in such cells is not known. We have used multiple myeloma (MM) cell lines to address this issue and find that an oncomiR, miR‐21 is induced after in vitro EBV infection. The PU.1 binding site in miR‐21 promoter was essential for its activation by the virus. In accordance with its noted oncogenic functions, miR‐21 induction in EBV infected MM cells caused downregulation of p21 and an increase in cyclin D3 expression. EBV infected MM cells were highly tumorigenic in SCID mice. Given the importance of miR‐21 in plasmacytoid malignancies, our findings that EBV could further exacerbate the disease by inducing miR‐21 has interesting implications both in terms of diagnosis and future miR based therapeutical approaches for the virus associated plasmacytoid tumors.     

Recurrent seminomas: Clinical features and biologic implications

ObjectivesCertain patients with seminoma and clinically atypical phenotypes—visceral metastases, elevated levels of β human chorionic gonadotropin (βHCG), and/or recurrent disease—have a poor prognosis. The primary goal of this pilot study was to characterize the clinical characteristics and treatment profile of these rare patients. We also wished to test whether these tumors expressed any specific biomarkers that might distinguish them as a unique subtype of seminoma.Materials and methodsWe retrospectively identified 25 patients with a history of seminoma plus visceral metastases, βHCG levels >200 mU/ml, and/or recurrent disease. We reviewed these patients' histories for treatment efficacy and clinical outcome. Tissue samples were available from 6 of those patients, and we studied them for expression of the markers OCT 3/4, PLAP, CD30, TRA-1-60, c-kit, and gp200. We compared our results with the expression of those markers in tissue samples from mixed seminoma/embryonal carcinomas and classic seminomas.ResultsOur analysis suggested that certain chemotherapeutic regimens (such as ifosfamide, paclitaxel, and cisplatin) are efficacious for the treatment of patients with these atypical seminomas. Further, specimens from the atypical seminomas generally had staining profiles that resembled those of classic seminomas and the seminoma components in mixed germ-cell tumors, but the profiles differed from those of the embryonal carcinoma components in the same mixed germ-cell tumors.ConclusionsAlthough these atypical seminomas tend to be resistant to chemotherapy, they may still respond to certain chemotherapeutic regimens. Our pilot immunohistochemical study also suggested that the unique phenotypes associated with these atypical seminomas do not result from any relationship with embryonal carcinomas. More study is needed to confirm these initial findings.     

Nonarteritic Anterior Ischemic Optic Neuropathy and Double Thrombophilic Defect: A New Observation

We report the first case of nonarteritic anterior ischemic neuropathy (NAION) associated with double thrombophilia: protein S deficiency and prothrombin G20210A mutation. A 58-year-old man is presented including the clinical and laboratory findings, cardiovascular profile and thrombophilia screening. The patient presented with 3/10 vision and an inferior altitudinal defect in the right eye. Funduscopic examination of the right eye revealed a hyperemic optic disk with blurred superior optic disk border and sectoral nerve fiber layer edema. Complete blood count, erythrocyte sedimentation rate and C-reactive protein were normal, suggesting a NAION. A workup of cardiovascular risk factors revealed hyperlipidemia, arterial hypertension and high-risk asymptomatic coronary artery disease. Due to the family history of deep vein thrombosis in the patient''s daughter, a thrombophilia screening was additionally performed. The results revealed a double thrombophilic defect, namely congenital protein S deficiency and heterozygosity for prothrombin G20210A mutation, which were also identified in the patient''s daughter. Anticoagulant warfarin therapy was initiated and the patient underwent a triple bypass surgery. At three-month follow-up, the right optic disk edema had resolved, leaving a pale superior optic nerve head. Visual acuity in the right eye had slightly improved to 4/10; however, the dense inferior altitudinal field defect had remained unchanged. The patient is currently treated with warfarin, atorvastatin, irbesartan and metoprolol. This case suggests that the first line of investigation in all patients with NAION involves assessment of cardiovascular risk factors. However, careful history taking will identify NAION patients who are eligible for additional thrombophilia screening: young patients without vasculopathic risk factors, bilateral or recurrent NAION, idiopathic or recurrent venous thromboembolism (VTE), positive family history of VTE, and VTE in young age or in unusual sites (e.g. cerebral, hepatic, mesenteric, or renal vein).Key Words: Anterior ischemic optic neuropathy, Thrombophilia, Prothrombin G20210A mutation, Protein S deficiency
