Clinical features of headache patients with fibromyalgia comorbidity

Our previous study assessed the prevalence of fibromyalgia (FM) syndrome in migraine and tension-type headache. We aimed to update our previous results, considering a larger cohort of primary headache patients who came for the first time at our tertiary headache ambulatory. A consecutive sample of 1,123 patients was screened. Frequency of FM in the main groups and types of primary headaches; discriminating factor for FM comorbidity derived from headache frequency and duration, age, anxiety, depression, headache disability, allodynia, pericranial tenderness, fatigue, quality of life and sleep, and probability of FM membership in groups; and types of primary headaches were assessed. FM was present in 174 among a total of 889 included patients. It prevailed in the tension-type headache main group (35%, p < 0.0001) and chronic tension-type headache subtype (44.3%, p < 0.0001). Headache frequency, anxiety, pericranial tenderness, poor sleep quality, and physical disability were the best discriminating variables for FM comorbidity, with 81.2% sensitivity. Patients presenting with chronic migraine and chronic tension-type headache had a higher probability of sharing the FM profile (Bonferroni test, p < 0.01). A phenotypic profile where headache frequency concurs with anxiety, sleep disturbance, and pericranial tenderness should be individuated to detect the development of diffuse pain in headache patients

A Robust DNA Isolation Protocol from Filtered Commercial Olive Oil for PCR-Based Fingerprinting

Extra virgin olive oil (EVOO) has elevated commercial value due to its health appeal, desirable characteristics and quantitatively limited production, and thus it has become an object of intentional adulteration. As EVOOs on the market might consist of a blend of olive varieties or sometimes even of a mixture of oils from different botanical species, an array of DNA-fingerprinting methods have been developed to check the varietal composition of the blend. Starting from a comparison between publicly available DNA extraction protocols, we set up a timely, low-cost, reproducible and effective DNA isolation protocol, which allows an adequate amount of DNA to be recovered even from commercial filtered EVOOs. Then, in order to verify the effectiveness of the DNA extraction protocol herein proposed, we applied PCR-based fingerprinting methods starting from the DNA extracted from three EVOO samples of unknown composition. In particular, genomic regions harboring nine simple sequence repeats (SSRs) and eight genotyping-by-sequencing-derived single nucleotide polymorphism (SNP) markers were amplified for authentication and traceability of the three EVOO samples. The whole investigation strategy herein described might favor producers in terms of higher revenues and consumers in terms of price transparency and food safety

Intra-oral orthosis vs amitriptyline in chronic tension-type headache: a clinical and laser evoked potentials study

BACKGROUND: In the present study, we examined clinical and laser-evoked potentials (LEP) features in two groups of chronic tension-type headache (CTTH) patients treated with two different approaches: intra-oral appliance of prosthesis, aiming to reduce muscular tenderness, and 10 mg daily amitriptyline. METHODS: Eighteen patients with diagnosed CTTH participated in this open label, controlled study. A baseline evaluation was performed for clinical features, Total Tenderness Score (TTS) and a topographic analysis of LEPs obtained manually and the pericranial points stimulation in all patients vs. healthy subjects. Thereafter, patients were randomly assigned to a two-month treatment by either amitriptyline or intra-oral appliance. RESULTS AND DISCUSSION: Both the intra-oral appliance and amitriptyline significantly reduced headache frequency. The TTS was significantly reduced in the group treated with the appliance. The amplitude of P2 response elicited by stimulation of pericranial zones showed a reduction after amitriptyline treatment. Both therapies were effective in reducing headache severity, the appliance with a prevalent action on the pericranial muscular tenderness, amitriptyline reducing the activity of the central cortical structures subtending pain elaboration CONCLUSION: The results of this study may suggest that in CTTH both the interventions at the peripheral and central levels improve the outcome of headache

A case of early-onset and monophasic trigeminal autonomic cephalalgia: could it be a SUNCT?

A 2-year-old female came to the Neurological Emergency Room of "Giovanni XXIII" Hospital in Bari, 6 h after the onset of severe facial pain, which occurred soon after awakening. Stabbing pain affected the right frontal and periorbital area, with ipsilateral conjunctival injection, swelling of the eyelids and tearing. Except the duration, from 5 to 30 s., the attacks were stereotyped including the occurrence and features of autonomic signs. Based on the typical clinical findings and the normal magnetic resonance imaging (MRI), we diagnosed short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing syndrome (SUNCT). The spontaneous remission within a few hours made prophylactic therapy unnecessary. At the last follow-up, after 3 months, the patient was still symptom free. In our case, after an active period lasting 2 days the disease disappeared completely. However the typical features of the disease (unilateral pain, short duration and high frequency of the attacks, autonomic signs ipsilateral to pain, numbers of attacks) were all present. While the diagnostic criteria of the International Headache Society classification for SUNCT did not include the duration of disease, it is likely that the active period lasting 2 days could be an expression of the clinical variability of the disease. © Springer-Verlag 2010

[MR imaging of the Tornwaldt's cyst: retrospective study of 1300 patients].

Tornwaldt's cyst is a benign developmental lesion of the nasopharynx, most of all midline located, originating from an outpouching of the pharyngeal mucosa caused by notocord retraction. Usually, the cyst represents an incidental finding of magnetic resonance study. The purpose of this study is to investigate the differential diagnostic aspects of Tornwaldt's cysts, making a comparison with other diseases of nasopharynx on the basis of morphological characteristics and signal, contributing to the previous statistical works

Ultrasound evaluation of ductal carcinoma in situ of the breast

Abstract Purpose: To assess the role of ultrasound (US) in detecting and characterizing ductal carcinoma in situ (DCIS) of the breast and to investigate the correlation between ultrasonographic and biological features of DCIS. Methods: In total, 171 patients (mean age 44; range 39-62) with 178 lesions were retrospectively evaluated by two independent radiologists searching for US mass or non-mass lesions. Immunohistochemistry analysis was performed to determine estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) expression. The US detection rate and pattern distribution among the lesion types were evaluated. The χ2 test was used to evaluate the correlation between the US findings and the biological factors. Statistical significance was indicated by p values &lt; 0.05. Inter-observer agreement was calculated by Kohen's k test. Results: US detected 35% (63/178) of all lesions. Fifty-two (83%) lesions were classified as mass lesions, and 11 (17%) as non-mass lesions (p &lt; 0.0001). Among the mass lesions, the most common shape was irregular (79%; p &lt; 0.0001), with 45 (87%) lesions having indistinct margins. Hypoechogenicity was the most common echo pattern (49 cases, 94%; p &lt; 0.0001). Microcalcifications were found in 23 cases (37%; p = 0.004) and were associated with mass lesions in 15 cases (65%) and with non-mass lesions in 8 cases (35%) (p = 0.21). An almost perfect inter-observer agreement (k = 0.87) was obtained between the two radiologists. A significant ER expression was found in mass lesions (83%; p &lt; 0.0001), with no significant PR (p = 0.89) or HER2 expression (p = 0.81). Among the lesions with microcalcifications, only 7 out of 23 cases (30%) were positive for HER2 (p = 0.09). Conclusion: DCIS represents a heterogeneous pathological process with variable US appearance (mass-like, non-mass-like, or occult). The most common US finding is represented by mass-type, hypoechogenic lesions with indistinct margins. A significant ER expression exists among mass-type lesions, while microcalcifications seem not to be associated with HER2 expression

The cerebral perivascular spaces: review of the literature on diffuse or focal expansion

Virchow-Robin spaces (VRS) are pial-lined, interstitial fluid-filled structures that do not directly communicate with the subarachnoid space, accompany penetrating arteries and veins and can be visualized on magnetic resonance imaging. This article reviews the imageology characteristics, the functions, the causes and the relation with neurological disorders of VRS

Lemierre's syndrome complicated by cerebral venous sinus thrombosis: A life threatening and rare disease successfully treated with empiric antimicrobial therapy and conservative approach

Lemierre's syndrome (LS) is a "forgotten" condition characterized by septic thrombophlebitis of the jugular vein that follows an otolaryngological infection. Fusobacterium necrophorum is the aetiological agent responsible for the syndrome in adolescents and young adults whereas in older people even common bacteria are involved. Complications arise from spreading of septic emboli distally, i.e. to the brain, lungs, bones and internal organs everywhere in the body. We report a middle-aged woman who presented with headache and bilateral sixth cranial nerve palsy following a sphenoidal sinusitis and left mastoiditis. Imaging revealed thrombotic involvement of the left internal jugular vein as well as of several cerebral venous sinuses thrombosis (CVT). Currently, precise management protocols of LS with CVT complication do not exist although a combination of macrolides and second or third-generation cephalosporins, as well as anti-coagulants represent the mainstream of therapeutics. Surgical drainage is associated to remove septic foci but is burdened by severe complications and side effects. Complete recovery was achieved following pharmacological treatment in our patient. This report adds further evidence that LS complicated by CVT may be effectively treated adopting a conservative approach thus avoiding surgical drainage and severe complications
