Anxiety disorders in headache patients in a specialised clinic: prevalence and symptoms in comparison to patients in a general neurological clinic

Data from several studies indicate an association of headache with anxiety disorders. In this study, we assessed and differentiated anxiety disorders in 100 headache patients by using the PSWQ (Penn State Worry Questionnaire) screening tool for generalised anxiety disorder (GAD) and the ACQ (Agoraphobic Cognitions Questionnaire) and BSQ (Body Sensation Questionnaire) for panic disorder (PD). Control groups were constructed: (1) on the basis of epidemiological studies on PD and GAD in the general population and (2) by including neurological patients. 37.0% of headache patients had a GAD. 27% of headache patients met the score for PD in the BSQ, 4.0% in the ACQ. Significant results were obtained in comparison to the general population (p < 0.001) and with regard to GAD in comparison with a sample of neurological patients (p < 0.005). The BSQ significantly correlated with the number of medication days (p < 0.005). The results confirm the increased prevalence of GAD in headache patients. PD seems to increase the risk of medication overuse

Topology Proceedings ON A CLASS OF SPECIAL NAMIOKA SPACES

Abstract We show that any Baire strict p-space is spe cial Namioka. For this purpose we introduce and study a class of spaces defined by means of a topological game. We also give some applica tions to semitopological group

On t-Conorm Based Fuzzy (Pseudo)metrics

[eng] We present an alternative approach to the concept of a fuzzy (pseudo)metric using t-conorms instead of t-norms and call them t-conorm based fuzzy (pseudo)metrics or just CB-fuzzy (pseudo)metrics. We develop the basics of the theory of CB-fuzzy (pseudo)metrics and compare them with 'classic' fuzzy (pseudo)metrics. A method for construction CB-fuzzy (pseudo)metrics from ordinary metrics is elaborated and topology induced by CB-fuzzy (pseudo)metrics is studied. We establish interrelations between CB-fuzzy metrics and modulars, and in the process of this study, a particular role of Hamacher t-(co)norm in the theory of (CB)-fuzzy metrics is revealed. Finally, an intuitionistic version of a CB-fuzzy metric is introduced and applied in order to emphasize the roles of t-norms and a t-conorm in this context

Headache in patients with a meningioma correlates with a bone-invasive growth pattern but not with cytokine expression

We included 58 patients with meningioma in a prospective study to analyse the prevalence of and risk factors for different types of meningioma-associated headache. Twenty-three patients (40%) had meningioma-associated headache. Of these, the pain was migraine-like in five (22%) and tension-type headache (TTH)-like in 13 (57%). Sixteen of 21 (76%) experienced relief of pain intensity of at least 50% after 18-24 months. Univariate analysis revealed bone-invasive growth pattern (P = 0.007) as a risk factor for headache and intake of antiepileptic drugs (P = 0.04) or large surrounding oedema (P = 0.04) as possible protective parameters. For migraine-like headache, risk factors were a positive history of migraine (P = 0.009) and bone-invasive growth pattern (P = 0.046) and, for TTH-like headache, only bone-invasive growth pattern (P = 0.009). Binary logistic regression analysis added to assess predictability and interaction effects could not identify a single factor predicting the occurrence of headache in the presence of a meningioma (correct prediction in 74% by a model consisting of bone-invasive growth pattern, history of head surgery, intake of antiepileptic drugs, temporal tumour location and moderate and large surrounding oedema). Analysis of 38 tumour specimens could not confirm the hypothesis that the occurrence of headache correlates with the expression magnitude of signal substances known to be present in meningiomas [stroma cell-derived factor 1, interleukin (IL)-1 beta, IL-6, vascular endothelial growth factor A] or thought to be relevant to headache/pain pathophysiology [prostaglandin-endoperoxide synthase 2, calcitonin-related polypeptide alpha, nitric oxide synthase (NOS) 1, NOS2A, NOS3, transforming growth factor-alpha, tumour necrosis factor, tachykinin, vasoactive intestinal peptide]. The affection of bone integrity and the expression of molecules thought to be relevant to headache pathophysiology might be important for meningioma-associated headache in predisposed individuals

Headache in patients with pituitary adenoma: Clinical and paraclinical findings

Aim: The aim of this article is to generate hypotheses for the mechanism of pituitary adenoma headache. Patients and methods: Fifty-eight patients with pituitary adenoma were prospectively analysed for prevalence and manifestation of tumour headache. Intrapersonal and neoplasm-associated risk factors were assessed. Results: Twenty-four patients (41%) had tumour-attributed headache, seven had migraine-like, 11 tension-type headache-like headache, and three both. Cluster headache-like headache was found once, and two headaches remained unclassified. Tumour-attributed headache was associated with a positive history of headache (p = 0.03; OR 3.4), nicotine abuse (p3% (p = 0.02; OR 11.0). For patients with migraine-like tumour-attributed headache, risk factors were younger age (p = 0.02), nicotine abuse (p3% (p = 0.03; OR 14.1). For tension-type headache-like headache, the main risk factor was a positive history of tension-type headache (p = 0.045; OR 5.6). Conclusion: Headache predisposition and local tumour effects might be important for the pathophysiology of pituitary adenoma headache and tumour headache in general

Cerebral angiitis in four patients with chronic GVHD

There is growing evidence that GVHD affects the central nervous system (CNS). In this study, we describe the long-term follow-up of four allogeneic BM recipients who developed cerebral angiitis-like disease probably due to GVHD. The patients developed focal neurological signs, cognitive deficits and/or coma in association with GVHD, 2–18 years after transplantation, following reduction of immunosuppressive therapy. Magnetic resonance imaging was variable, showing generalized brain atrophy, ischemic lesions or leukoencephalopathy. Diagnosis of cerebral angiitis was confirmed by histopathological analysis of bioptic brain tissue and response to immunosuppressive therapy. By means of immunohistochemistry and immunofluorescence, perivascular lymphomononuclear cerebral infiltrates were shown to express the adhesion receptor, CD11a, and the chemokine receptor, CCR5. Our findings imply that GVHD should be considered in the differential diagnosis of noninfectious angiitis-like disease of the CNS in long-term survivors after allogeneic BMT. Infiltrating cells, in analogy to typical target organs of GVHD such as skin or liver, expressed CD11a and CCR5. These findings could be of etiopathological, diagnostic and therapeutic relevance
