Article: The accuracy of discharge diagnosis coding for Amyotrophic Lateral Sclerosis in a large teaching hospital
[show abstract] [hide abstract]
ABSTRACT: To evaluate the accuracy of hospital discharge data as a source of Amyotrophic Lateral Sclerosis (ALS) cases for epidemiological studies or disease registries, a validation study was performed. All records of patients discharged in 2005 and 2006 with principal or secondary International Classification of Diseases, 9th rev., Clinical Modification (ICD 9 CM) diagnosis code of ALS (335.20), other anterior horn cell disease (335), spinal cord disease (336), hereditary and idiopathic peripheral neuropathy (356), inflammatory and toxic neuropathy (357), myoneural disorders (358), muscular dystrophies and myopathies (359), were selected from the electronic archive of discharge data of the University Hospital of Udine, Friuli Venezia Giulia Region, North East Italy. Corresponding clinical documentation was reviewed to ascertain the presence of El Escorial criteria, the gold standard. Sensitivity of the ICD 9 CM discharge code 335.20 was 93% (95%CI: 82–99%) and decreased to 91% (95%CI: 77–98%) when suspect ALS was excluded. Specificity was 99% (95%CI: 97–99%). The ICD 9 CM discharge code 335.20 can identify a high percentage of hospitalizations of patients truly affected by ALS and of patients with no ALS, among selected neurological diagnostic codes. To ensure complete ALS case ascertainment, prospective population-based registries or epidemiologic studies require active prospective surveillance and use of multiple sources, among them hospital discharge archives can provide accurate information.European Journal of Epidemiology 04/2012; 24(10):635-640. · 4.71 Impact Factor -
Article: Migraine in adolescents: validation of a screening questionnaire.
[show abstract] [hide abstract]
ABSTRACT: Few studies in adolescents deal with the level of agreement between questionnaire and interview information in relation to headache symptoms. To evaluate the validity of a self-administered questionnaire on headache for use in epidemiological studies of Italian high school students. The questionnaire incorporated all items required for diagnosing migraine according to the criteria from the 2004 International Classification of Headache Disorders. The migraine diagnoses obtained from questionnaires were validated against the gold standard diagnoses by a headache specialist. Out of 104 students answering the questionnaires, 93 (89.4%) participated in extensive semi-structured interviews by a neurologist. The chance-corrected agreement rate (kappa) was 0.66, which is considered good. The questionnaire-based migraine diagnosis had a sensitivity of 67.3%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 73.3%. The results indicate that our self-administered questionnaire may be an acceptable instrument in determining the prevalence of migraine sufferers in the northeast Italy adolescent population, useful in identifying subjects with "definite" migraine.Headache The Journal of Head and Face Pain 03/2009; 49(2):202-11. · 2.52 Impact Factor -
Article: Anticancer drugs and central nervous system: clinical issues for patients and physicians.
[show abstract] [hide abstract]
ABSTRACT: Anticancer drugs may cause neurological toxicity involving the central nervous system. Patients receiving anticancer treatment may develop encephalopathy, extrapyramidal reactions, seizures, cerebellar dysfunction, retinopathy, cerebral venous thrombosis, myelopathy, cognitive impairment, and psychiatric symptoms. Physician should carefully evaluate neurological signs and symptoms in order to recognize these drug-related adverse reactions. In this review we aimed at presenting different neurological complications of anticancer drugs and their management. PUBMED search was performed in order to retrieve all articles and case reports dealing with central nervous system toxicity related to anticancer treatments.Cancer Letters 09/2008; 267(1):1-9. · 4.24 Impact Factor -
Article: Paraneoplastic neurological syndromes and breast cancer. Regression of paraneoplastic neurological sensorimotor neuropathy in a patient with metastatic breast cancer treated with capecitabine: a case study and mini-review of the literature.
[show abstract] [hide abstract]
ABSTRACT: Paraneoplastic neurological syndromes are a rare complication of breast cancer. Nevertheless, they may be clinically relevant leading to neurological impairment. Clinicians should be aware that these neurological disorders could even precede the diagnosis of breast cancer. Here we present the case of a female patient with advanced breast cancer who developed paraneoplastic sensorimotor neuropathy. Treatment with capecitabine lead to clinical amelioration. A review of the literature on the paraneoplastic neurological syndromes in breast cancer is also included.Breast Cancer Research and Treatment 11/2007; 105(2):133-8. · 4.43 Impact Factor -
Article: Sensory gating deficit assessed by P50/Pb middle latency event related potential in Alzheimer's disease.
[show abstract] [hide abstract]
ABSTRACT: Sensory gating is defined as the brain's ability to inhibit repetitive and irrelevant incoming sensory stimuli and is supposed to be related to cholinergic transmission. Indeed, Alzheimer's disease (AD) is characterized by a cholinergic deficit that is believed to be involved in cerebral cortex hyperexcitability and short latency afferent inhibition deficit. Therefore, a sensory gating deficit may be supposed present in AD within the frame of cortex hyperexcitability and loss of cortex modulation of sensory inputs. The authors investigated whether a sensory gating deficit may be present in AD and whether this deficit may be related to the presence of neuropsychiatric symptoms (NPS) and reversed by donepezil treatment. Sensory gating was evaluated using a paired-stimulus auditory P50 event-related potential paradigm. Eighteen drug-naïve probable AD patients (mean age 76.1 years; SD 5.6 years; 13 females and 5 males) and 15 healthy elderly controls (mean age 74.2 years; SD 5.4 years; 10 females and 5 males) were recruited. Sensory gating was evaluated in AD patients before starting therapy and after 1 and 3 months of donepezil treatment. Auditory P50 sensory gating was impaired in AD patients but no correlation was found between gating deficit and NPS. Moreover, AD patients displayed increased P50 amplitude when compared with healthy elderly subjects. Donepezil treatment did not improve P50 sensory gating in AD patients but decreased P50 amplitude. Patients with AD displayed an augmented P50 amplitude, in accordance with previous studies, suggesting increased cortex excitability. Donepezil does not affect P50 sensory gating but reduces P50 amplitude. Donepezil may induce P50 amplitude reduction by means of enhanced dopamine release. Indeed, it has been demonstrated that donepezil induces dopamine release "in vitro." The findings suggest that AD patients have a sensory gating impairment but the link with both NPS and the cholinergic deficit is doubtful.Journal of Clinical Neurophysiology 11/2006; 23(5):421-5. · 1.45 Impact Factor -

Article: Neuropathological and clinical phenotype of an Italian Alzheimer family with M239V mutation of presenilin 2 gene.
[show abstract] [hide abstract]
ABSTRACT: Presenilin 1 and 2 are 2 highly homologous genes involved in familial Alzheimer disease. While more than 100 mutations in presenilin 1 are known to segregate with the disease in familial Alzheimer disease, only 9 mutations of presenilin 2 have been identified to date. We report the clinical and neuropathological phenotype of FLO10, the large Italian Alzheimer kindred associated with methionine to valine substitution at residue 239 of presenilin 2. The patients showed a remarkable variability in age of onset of symptoms, disease duration, and clinical presentation. The neuropathological study of 2 patients revealed peculiar features in addition to neurofibrillary changes and A beta amyloid deposits in the neuropil and vessel wall. Ectopic neurons in the subcortical white matter, often containing neurofibrillary tangles, were found in both patients, one of whom presented with epilepsy. Furthermore, 1 patient showed an unusually high number of ghost tangles in the cerebral cortex. These observations indicate that the Alzheimer kindred FLO10 associated with M239V mutation of presenilin 2 is characterized by some peculiarities of the clinical and neuropathologic phenotype compared to sporadic Alzheimer disease.Journal of Neuropathology and Experimental Neurology 04/2004; 63(3):199-209. · 4.26 Impact Factor -
