Gabapentin-responsive idiopathic stabbing headache.

Idiopathic stabbing headache (ISH) is defined as the occurrence of short-lasting, painful jabs, restricted to the ophthalmic division of the trigeminal nerve. It is closely related to other forms of headache (such as migraine and tension-type headache) and has been reported among all age groups, including children and adolescents. As pathogenic mechanisms of the disease remain unclear, management decisions are empirical and limited to few options. Classically, indomethacin has been considered the first option, but therapeutic failure occurs in up to 35% of cases. In this setting, we report four patients with young-onset indomethacin-resistant ISH which had good responses to gabapentin and discuss the use of this drug in the presenting situation.

Comparison of short-term outcome between surgical and clinical treatment in temporal lobe epilepsy: A prospective study

OBJECTIVE To compare the efficacy of medical and surgical treatment for refractory mesial temporal lobe epilepsy associated with hippocampal sclerosis (MTLE). METHODS A prospective controlled non-randomized study of 26 patients with MTLE who underwent surgical treatment and 75 patients with MTLE who underwent medical treatment between August 2002 and October 2004. All patients failed to achieve seizure control with at least two first line antiepileptic drugs (AED) for partial seizures before entering the study. We used Kaplan-Meier survival analyses as a function of time of seizure recurrence to obtain estimates of 95% confident interval of seizure freedom and log-rank test to compare the status of seizure control between the two groups. RESULTS The cumulative proportion of patients free of all seizures (Engels class IA) was higher in the surgical group (73%) compared to the clinical group (12%) (p<0.0001). In the surgical group, 2 of 26 patients (7.7%) had transient adverse effects and 2 of 26 patients (7.7%) had a permanent deficit related to the surgical procedure. In the clinical group 7 patients (9.3%) major adverse events during follow-up, including burns and status epilepticus. CONCLUSIONS Surgical treatment for patients with MTLE who failed to achieve seizure control with two previous AED regimens was more efficient than medical treatment with further trials of AED.

Epilepsias generalizadas idiopáticas diagnosticadas incorretamente como epilepsias parciais

Idiopathic generalized epilepsy (IGE) is often not recognized with serious consequences on the sufferers. We examined factors contributing to the missed diagnosis of IGE in 41 adults attending our epilepsy clinic with diagnosis of partial epilepsy who had semiology or EEG findings suggesting a possible differential diagnosis. After careful re-evaluation, the diagnosis of IGE was established in 25 patients: 22 (88%) with JME, one with juvenile absence, one with perioral myoclonia with absences, one with eyelid myoclonia with typical absences. Myoclonic jerks, the hallmark of the JME and other IGE, were not usually reported by patients or misdiagnosed as focal motor seizures. Brief and infrequent absence seizures and focal EEG abnormalities were other factors contributing to not recognizing JME. All 25 patients did not achieve seizure control before re-evaluation of diagnosis. After appropriate diagnosis of IGE and change of AED to valproate or valproic acid, 19 (76%) became seizure free and six (24%) had a significant improvement on seizure control. Association with lamotrigine provided further improvement in three of these patients. An appropriate questioning to identify myoclonic and absence seizures and a proper interpretation in the context of whole clinical constellation are essential for a correct seizure classification and diagnosis of IGE in adults.

Quality of life in pregnant women with epilepsy versus women with epilepsy

It is assumed that 25% of patients with epilepsy are women of fertile age and 0.3% to 0.6% of all children are born of mothers with epilepsy. The aim of this study was to evaluate the quality of life on pregnant with epilepsy and compare with non-pregnant women with epilepsy. We evaluated two groups (Experimental Group--29 pregnant women with epilepsy and Control Group--30 women with epilepsy); they were attended at the HC/UNICAMP. The patients had three meetings to carry out and implement the anamnesis and the application of QQV-65. There were no significant differences in the measurement of quality of life when comparing both groups. However, when we analyzed individually in the pre- and post-partum periods, we observed significant differences in health aspects (p=0.0495), physical (p=0.02868) and emotional (p=0.0253) dimensions in QQV-65. This study shows that pregnancy could be interpreted as a stressor. In late pregnancy when this stressor was removed, women with epilepsy had improvement in their quality of life.

Neurocysticercotic Calcifications and Hippocampal Sclerosis: A Case-Control Study

Objective The exact role of calcified neurocysticercotic lesions (CNLs) in epilepsy is yet unknown and controversial. Although the relationship between CNLs, epilepsy and mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) has already been addressed, to our knowledge, no study has actually provided strong statistical evidence, nor reported the ODDS ratio for these associations. Therefore, we designed this case-control study to assess the likelihood of having MTLE-HS versus other forms of epilepsy in the presence of CNLs. Methods In this case-control study we included 119 consecutive patients with epilepsy and 106 disease controls (headache) with previous CT scans. We subdivided cases into MTLE-HS and other epilepsies. We used brain CT scans to define presence or absence of CNLs. After exploratory analyses, we used logistic regression to analyze the association between CNLs, epilepsy subgroups and disease controls. Results CNLs were found in 31.09% of cases and in 11.32% of controls (p<0.001). The initial analysis comparing epilepsy versus controls revealed a significant association between CNLs and epilepsy (OR = 5.32; 95%CI = 2.43-11.54; p<0.001). However, when we compared MTLE-HS versus other epilepsies versus controls we confirmed that CNLs were associated with MTLE-HS (OR = 11.27, 95%CI = 4.73-26.85; p<0.001) but other epilepsies were not. We found no difference in the CNLs load and no difference in the location of the CNLs when we compared patients with MTLE-HS, other epilepsies and disease controls. Significance The inclusion of controls allowed us to estimate the likelihood of having epilepsy in the presence of CNLs. We found that patients with CNLs were 11 times more likely to have MTLE-HS; however, the presence of CNLs did not change the odds of having other types of epilepsy. These findings raise the possibility of neurocysticercosis playing a role in the pathophysiology of MTLE-HS and need further confirmation in other series.

Trigemino autonomic cephalalgia and Argyll Robertson pupil.

. The group comprises episodic and chronic clus-ter headache, chronic and episodic paroxysmal hemicra-nia, and SUNCT syndrome. SUNA syndrome (short-lasting unilateral neuralgiform headache attacks with cranial au-tonomic symptoms), although not classified as a TAC, also shares some common characteristics with this group and may include the SUNCT definition. Despite their common elements, the TACs differ in response to therapy, frequen-cy and duration of attacks. They must be differentiated from secundary TACs because of the possible serious and treatable underlying causes, like mass lesions, subarach-noid hemorrhage, pathology in the base of the skull and others
