Sporadic hemiplegic migraine and CREST syndrome

Interrelated Pathogenesis? Neuronal Intranuclear Inclusion Disease Combining With Hemiplegic Migraine

BACKGROUND

Neuronal intranuclear inclusion disease (NIID) is considered a heterogeneous disease because of its highly variable clinical manifestations. To date, there are no reports of NIID patients presenting with hemiplegic migraine (HM)-like headache, or of HM and NIID co-occurring as comorbidity, and the connection between these 2 seemingly unrelated clinical conditions has yet to be established.

METHOD

We present a patient with NIID who was previously diagnosed with HM. To determine the pathogenesis of HM in this NIID patient, we systematically reviewed published NIID and HM cases and cataloged them based on their clinical manifestations.

RESULT

The clinical manifestations of NIID is highly various; however, there is no case reported to date that shows HM-like symptoms or cerebral edema. All documented symptomatic HM cases show vascular dysfunction to various degrees, but none of them has been shown to be correlated with NIID.

CONCLUSION

Our patient is the first documented case in which HM and NIID occur simultaneously. Vascular dysfunctions that cause cerebral hypoperfusion and glucose hypometabolism, two of the dominant causes of symptomatic HM, may be associated with the accumulation of eosinophilic hyaline inclusions that cause NIID. However, the existence of inclusions may also alter neuronal behavior and indirectly cause cerebral hypoperfusion and glucose hypometabolism. Further research and observations are needed to examine the relationship between HM and NIID.

Neurologic involvement in scleroderma: a systematic review

OBJECTIVES

To perform a systematic review of neurologic involvement in Systemic sclerosis (SSc) and Localized Scleroderma (LS), describing clinical features, neuroimaging, and treatment.

METHODS

We performed a literature search in PubMed using the following MeSH terms, scleroderma, systemic sclerosis, localized scleroderma, localized scleroderma "en coup de sabre", Parry-Romberg syndrome, cognitive impairment, memory, seizures, epilepsy, headache, depression, anxiety, mood disorders, Center for Epidemiologic Studies Depression (CES-D), SF-36, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Patient Health Questionnaire-9 (PHQ-9), neuropsychiatric, psychosis, neurologic involvement, neuropathy, peripheral nerves, cranial nerves, carpal tunnel syndrome, ulnar entrapment, tarsal tunnel syndrome, mononeuropathy, polyneuropathy, radiculopathy, myelopathy, autonomic nervous system, nervous system, electroencephalography (EEG), electromyography (EMG), magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA). Patients with other connective tissue disease knowingly responsible for nervous system involvement were excluded from the analyses.

RESULTS

A total of 182 case reports/studies addressing SSc and 50 referring to LS were identified. SSc patients totalized 9506, while data on 224 LS patients were available. In LS, seizures (41.58%) and headache (18.81%) predominated. Nonetheless, descriptions of varied cranial nerve involvement and hemiparesis were made. Central nervous system involvement in SSc was characterized by headache (23.73%), seizures (13.56%) and cognitive impairment (8.47%). Depression and anxiety were frequently observed (73.15% and 23.95%, respectively). Myopathy (51.8%), trigeminal neuropathy (16.52%), peripheral sensorimotor polyneuropathy (14.25%), and carpal tunnel syndrome (6.56%) were the most frequent peripheral nervous system involvement in SSc. Autonomic neuropathy involving cardiovascular and gastrointestinal systems was regularly described. Treatment of nervous system involvement, on the other hand, varied in a case-to-case basis. However, corticosteroids and cyclophosphamide were usually prescribed in severe cases.

CONCLUSIONS

Previously considered a rare event, nervous system involvement in scleroderma has been increasingly recognized. Seizures and headache are the most reported features in LS en coup de sabre, while peripheral and autonomic nervous systems involvement predominate in SSc. Moreover, recently, reports have frequently documented white matter lesions in asymptomatic SSc patients, suggesting smaller branches and perforating arteries involvement.

Migraine variants--occurrence in pediatric neurology practice

Migraine is common in pediatric neurology practice, while migraine variants are rare and pose diagnostic problems.

OBJECTIVE

The aim was to establish the occurrence of migraine variants in pediatric neurology practice and among migraine, and to discuss their presentation.

PATIENTS AND METHODS

The files of 2509 newly diagnosed patients, aged 0-18 years, treated as in- and out-patients in the Neuropediatric Ward at the Plovdiv Medical University Hospital between 2002 and 2006 were examined retrospectively. Migraine forms were diagnosed according to ICHD-II. Benign paroxysmal torticolis and alternating hemiplegia of childhood were also accepted as migraine variants according to proposed diagnostic criteria in the appendix of ICHD-II. Some specific forms like acute confusional migraine (ACM), Alice in wonderland syndrome (AWS), ophthalmoplegic migraine were also diagnosed although not included as migraine variants in the ICHD-II classification.

RESULTS

111 patients met diagnostic criteria for migraine. Patients with migraine variants comprised 24.3% of migrainous cases. Basilar type migraine was the most common (6.3% of all migrainous patients), followed by benign paroxysmal vertigo (5.4%), hemiplegic migraine (3.6%), ACM (2.7%), benign paroxysmal torticolis (2.7%), typical aura without headache (1.8%), abdominal migraine (1.8%), AWS (0.9%), ophthalmoplegic migraine (0.9%) and cyclical vomiting (0.9%). Alternating hemiplegia of childhood and retinal migraine was not found. Some patients either presented or were classified as different migraine variants.

CONCLUSION

Basilar type migraine was the most common migraine variant. ACM and AWS should be regarded as distinct entities in the ICHD as migraine with complex aura. Benign paroxysmal torticollis also deserves its place as a migraine variant. Cases of ophthalmoplegic migraine with spontaneous remission and no cranial nerve enhancement on MRI should be considered as migraine form. Analyzing migraine variants will contribute to better awareness and adequate diagnosis.
