A comparative ID migraine screener study in ophthalmology, ENT and neurology out-patient clinics.

Migraine is more likely to be misdiagnosed in patients with comorbid diseases. Not only primary care physicians, but also specialists might misdiagnose it due to the lack of diagnostic criteria awareness. The ID migraine test is a reliable screening instrument that may facilitate and accelerate migraine recognition. This study aimed to compare the prevalence and characteristics of migraine in a large sample of patients admitted to clinics of ophthalmology (OC), ear, nose and throat diseases (ENTC) and neurology (NC), as well as to validate the use of the ID migraine test in OC and ENTC settings. This was a multicentre (11 cites) study of out-patients admitting either to NC, ENTC or OC of the study sites during five consecutive working days within 1 week. From each of the clinics, 100 patients were planned to be recruited. All recruited patients were interviewed and those having a headache complaint received an ID migraine test and were examined for headache diagnosis by a neurologist, blinded to the ID migraine test result. A total of 2625 subjects were recruited. Only 1.3% of OC patients and 5.4% of ENTC patients have been admitted with a primary complaint of headache, whereas the percentage of NC patients suffering from headache was 37.6%. Whereas 138 patients (19.3%) in OC, 154 (17.3%) in ENTC and 347 (34%) in NC were found to be ID migraine test positive, 149 patients (20.8%) in OC, 142 (16%) in ENTC and 338 (33.1%) in NC were diagnosed with migraine. The sensitivity, specificity, and positive and negative predictive ratios of the ID migraine test were found to be similar in all clinics. An important fraction of the patients admitted to NC, as well as to OC and ENTC, for headache and/or other complaints were found out to have migraine by means of a simple screening test. This study validated the ID migraine test as a sensitive and specific tool in OC and ENTC, encouraging its use as a screening instrument.

Migrainous vertigo: clinical, oculographic and posturographic findings.

Migrainous vertigo (MV) is accepted as a common cause of episodic vertigo. The peripheral or central vestibular localization of the deficit as well as the pathophysiology is unclear. This prospective study was designed to assess the clinical features of MV and to search for the localization of the vestibular pathology. Thirty-five patients with MV, 20 patients with migraine and 20 healthy volunteers were studied. Comprehensive neurotological tests were performed between attacks. None of the normal controls or the patients with migraine had ocular motor deficits or caloric test abnormalities. Three patients in the MV group showed saccadic pursuit (8.6%), in one of whom saccadic hypometria was also present. Caloric test results revealed unilateral caloric hypofunction in seven patients (20%). Static posturography results revealed increased sway velocity when the eyes were closed or the platform was distorted in patients with MV. These findings during the symptom-free period revealed that peripheral vestibular dysfunction was more common than a central deficit.

Headache in primary Sjögren's syndrome: a prevalence study.

OBJECTIVES: To determine the prevalence of headache in patients with primary Sjögren's syndrome (pSS) and to examine the relationship between headache types and clinical, serologic features of the disease. METHODS: The study enclosed 133 patients with the diagnoses of pSS and 97 healthy controls. A questionnaire designed to assess the presence of headache and if present to classify it according to the criteria of the International Headache Society was used. RESULTS: In 133 of the pSS patients evaluated, 104 had headache. No association was present between types of headache and the clinical and laboratory manifestations of the disease. Both migraine and tension-type headache were more common in patients with pSS when compared with healthy controls (P < 0.001). CONCLUSIONS: The high prevalence of migraine in pSS patients might be explained by a vascular headache triggered by immuno-mediated disease activity without an obvious clinic or laboratory marker.

Is vestibular rehabilitation as effective in bilateral vestibular dysfunction as in unilateral vestibular dysfunction?

BACKGROUND: Bilateral vestibular dysfunction causes serious disabilities and handicaps. Patients with bilateral dysfunction often restrict their activities and tend to be unsocial. AIM: To compare the effects of vestibular rehabilitation on disability, balance, and postural stability in patients with unilateral and bilateral vestibular dysfunction. DESIGN: Retrospective study. SETTING: Outpatient rehabilitation center. POPULATION: Patients with unilateral (group 1, N.=42) and bilateral vestibular dysfunction (group 2, N.=19). METHODS: All patients were evaluated before and after eight weeks of customized vestibular rehabilitation for disability (Dizziness Handicap Inventory [DHI], Activities-specific Balance Confidence Scale [ABC]), dynamic balance (Timed Up and Go Test [TUG], Dynamic Gait Index [DGI]), and postural stability (static posturography). RESULTS: The differences between DHI, TUG, DGI, and falling index (as assessed by static posturography) scores before and after the exercise program were statistically significant in both groups (P<0.05). There were no significant intergroup differences in any of the parameters evaluated (P>0.05). CONCLUSION: In this study, vestibular rehabilitation was found to be equally effective in unilateral and bilateral vestibular dysfunction patients for improving disability, dynamic balance, and postural stability. CLINICAL REHABILITATION IMPACT: Patients with bilateral dysfunction, causing more disability and greater handicap may indeed regain their functions as in patients with unilateral vestibular dysfunction by receiving appropriate and adequate vestibular rehabilitation.

Treatment of idiopathic intracranial hypertension: topiramate vs acetazolamide, an open-label study.

OBJECTIVES - To assess the efficacy of topiramate in the treatment of idiopathic intracranial hypertension (IIH) and to compare it with acetazolamide. METHODS - Fourty patients diagnosed as IIH and randomly assigned to treatment with either acetazolamide or topiramate were assessed prospectively. Improvement in the visual fields at the end of third, sixth and twelfth months were taken into consideration. RESULTS - The demographic, clinical features and the cerebrospinal fluid (CSF) pressure of the two treatment groups were similar at the beginning of the study. When the follow-up visual field grades were compared with the visual field grades at the beginning of the study in each group a statistically significant improvement was detected with both drugs. When the results of the two treatment groups were compared with each other no statistically significant difference was present. Prominent weight loss was recorded in the topiramate group. CONCLUSIONS - Topiramate seems to be effective in the treatment of IIH. Weight reduction as well as the reduction of the CSF formation is the possible mechanism of action.

X-linked spastic paraplegia.

This paper describes a family with 10 males affected by x-linked spastic paraplegia. X-linked inheritance is rarely encountered in pure and complicated forms of hereditary spastic paraplegia. The disease was characterized by hyperreflexia, progressive spastic gait disorder, extensor plantar responses and mental retardation in all of the affected members of the family we studied. In addition to these symptoms, the older patients had cerebellar findings, severe disability and contractures. This is the 13th family manifesting x-linked spastic paraplegia reported in the literature.
