ABSTRACT
Idiopathic hypertrophic cranial pachymeningitis is a very infrequent disorder. Adequate management is still a matter of debate. We describe the use of low-dose pulse methotrexate in treating a 63-year-old woman with idiopathic hypertrophic cranial pachymeningitis. A weekly scheme with subcutaneous methotrexate was tried. Clinical improvement occurred in one week. Total remission of the clinical and neuro-imaging abnormalities was evident 6 months later, with minimal side effects. The patient is in complete remission after one year of follow-up without treatment. Hence, low-dose weekly subcutaneous methotrexate may be safe and effective in inducing complete and sustained remission of this condition. The experience with subcutaneous methotrexate to treat this entity has never been reported.

Introducción. La esclerodermia lineal en golpe de sable, mejor conocida como esclerodermia lineal en coup de sabre (ELCS), es una enfermedad rara de causa incierta, caracterizada por atrofia focal progresiva craneofacial y, en parte, es diferente al síndrome de Parry-Romberg (SPR). Casos clínicos. Comunicamos tres pacientes con ELCS (2 mujeres y 1 hombre, con un promedio de edad de 40 años). Las manifestaciones neurológicas principales fueron cefalea y crisis convulsivas. Los alteraciones radiológicas, aunque diversas, fueron todas ipsilaterales al golpe de sable. En una paciente sometida a biopsia se obtuvo evidencia histopatológica de gliosis e infiltrado inflamatorio mixto perivascular. Destacamos en otro paciente la afectación cerebrovascular, dado el hallazgo de un infarto cerebeloso antiguo subclínico y oclusión de la arteria cerebelosa superior en ausencia de otra posible causa. Conclusiones. La ELCS, cuando afecta al sistema nervioso central es heterogénea en su presentación clínica y radiológica. Los estudios de imagen durante el control clínico y los hallazgos histopatológicos apoyan un proceso inflamatorio focal que puede ser progresivo. La afectación arterial se debe probablemente a una vasculopatía inflamatoria no ateroesclerosa, oclusiva y crónica (AU)
Introduction. Sword stroke linear scleroderma, which is better known as linear scleroderma en coup de sabre (LSCS), is a rare disease with an uncertain causation that is characterised by progressive craniofacial focal atrophy and is, at least in part, different from Parry-Romberg syndrome (PRS). Case reports. Here, we report on the cases of 3 patients with LSCS (2 females and 1 male, with a mean age of 40 years). The main neurological symptoms were headache and seizures. Although different alterations were observed in the X-ray images, they were all ipsilateral to the coup de sabre. Histopathological evidence for gliosis and mixed perivascular inflammatory infiltrate was found in the study of a biopsy specimen taken from one female. Cerebrovascular involvement was seen in another patient, as highlighted by the observation of an earlier subclinical cerebellar infarct and occlusion of the superior cerebellar artery in the absence of any other possible causation. Conclusions. When it affects the central nervous system, the clinical and radiological presentation of LSCS is heterogeneous. Both the imaging studies carried out during the clinical control and the histopathological findings suggest a focal inflammatory process that can be progressive. The arterial involvement is probably due to a non-atherosclerotic, occlusive and chronic inflammatory disease of the peripheral vessels (AU)

INTRODUCTION: 'Sword stroke' linear scleroderma, which is better known as linear scleroderma en coup de sabre (LSCS), is a rare disease with an uncertain causation that is characterised by progressive craniofacial focal atrophy and is, at least in part, different from Parry-Romberg syndrome (PRS). CASE REPORTS: Here, we report on the cases of 3 patients with LSCS (2 females and 1 male, with a mean age of 40 years). The main neurological symptoms were headache and seizures. Although different alterations were observed in the X-ray images, they were all ipsilateral to the coup de sabre.

CONCLUSIONS: When it affects the central nervous system, the clinical and radiological presentation of LSCS is heterogeneous. Both the imaging studies carried out during the clinical control and the histopathological findings suggest a focal inflammatory process that can be progressive. The arterial involvement is probably due to a non-atherosclerotic, occlusive and chronic inflammatory disease of the peripheral vessels.

INTRODUCTION: Intracerebral haemorrhage (ICH) has received little attention in studies in Mexico. Isolated reports talk of high frequency, its importance as a disorder among young people, its being mainly located in the lobar regions and a high rate of recurrence. AIMS: The objective of this study was to characterise the clinical, radiological, therapeutic and prognostic spectrum of ICH in a general hospital in the central-western region of Mexico. PATIENTS AND METHODS: The study involved 270 consecutive patients over the age of 15 years with spontaneous ICH who were hospitalised in the Neurology and Neurosurgical Service in the Antiguo Hospital Civil de Guadalajara between the years 2000 and 2002. Their clinical history and progression was known at least on discharge from the hospital. RESULTS: The mean age was 63 years (12% under 40 years old) with no predominance according to gender (53% males). Arterial hypertension was the main risk factor in 69%, followed by obesity in 38%. There were no differences in the Glasgow administered on admission in three pre-established subgroups. The ICH was ganglionic in 64% of cases and lobar in 24%. Arterial hypertension was the principal cause of ICH in 76%. Ventricular aperture was noted in 53%. All the patients were treated in a general ward. Mortality in the acute phase occurred in 49%, although a poor progression was observed in 83%. Overall recurrence was 13%. Outpatient follow-up was poor. CONCLUSIONS: ICH shares most of the features reported in Anglo-Saxon series including aetiology and location. In our population, mortality and recurrence are high with important sequelae. The high frequency of ICH (40%) may represent a bias in the selection of hospitals.

Introducción. La hemorragia intracerebral (HIC) se ha estudiado escasamente en México. Algunos comunicados aislados señalan una elevada frecuencia, importante afectación en jóvenes, mayor localización lobar y alta recurrencia. Objetivos. Caracterizar el espectro clínico, radiológico, terapéutico y pronóstico de la HIC en un hospital general de la región centro-occidente de México. Pacientes y métodos. Se incluyeron 270 pacientes consecutivos mayores de 15 años con HIC espontánea ingresados en el Servicio de Neurología y Neurocirugía del Antiguo Hospital Civil de Guadalajara, entre los años 2000 y 2002. Todos tenían historia clínica y una evolución conocida, al menos, hasta el alta hospitalaria. Resultados. La edad promedio fue de 63 años (12% menores de 40 años) sin predominio de sexo (53% hombres). La hipertensión arterial fue el principal factor de riesgo (69%), seguida de la obesidad (38%). No hubo diferencia en el Glasgow al ingreso en tres subgrupos preestablecidos. La localización de la HIC fue ganglionar en el 64% y lobar en el 24%. La hipertensión arterial fue la principal causa de HIC en el 76%. La apertura ventricular se consignó en un 53%. Todos los pacientes se trataron en la sala general. La mortalidad en fase aguda se dio en el 49%, aunque se consignó una mala evolución en el 83%. La recurrencia global fue de 13%. El seguimiento por consulta externa es pobre. Conclusiones. La HIC comparte la mayoría de las características comunicadas en series anglosajonas con inclusión de etiología y localización. En nuestra población, la mortalidad y la recurrencia son altas, con secuelas importantes. La elevada frecuencia de HIC (40%) puede representar un sesgo de selección hospitalaria (AU)

EEGs and behavioral responses were studied in two sex matched groups of 58 epileptic and 20 healthy children between 8 and 12 years of age, during the execution of a go-no go CPT (X; A-X) task to determine transitory cognitive impairment (TCI) incidence. Paroxysmal discharges were found on 87.9% and 5% of the EEGs in the epileptic and control groups respectively, with no differences related to sex. The predominant EEG findings with respect to paroxysmal discharges were the association of two or more types of paroxysms with frequency higher than 5/minute, an average duration less than 0.5 second and topographical distribution over temporal-parietal-occipital areas without significant interhemispheric differences. TCI was detected in 36.2% of epileptic children. The epileptic group showed significantly higher numbers of behavioral errors and longer reaction times (RTs) in relation to the control group. Analyzing RTs on the two blocks of the task, linear discriminant analysis showed an acceptable classification of TCI incidence between groups.

In this report, we describe four cases of granulomatous amebic encephalitis caused by Balamuthia (Leptomyxid ameba) in four previously healthy Mexican patients. All four cases were characterized by focal neurologic signs, increased intracranial pressure, and cerebral hyperdense lesions in computed tomography scans of the head. These patients underwent craniotomies for evaluation of mass lesions for possible brain tumors. Granulomatous chronic inflammatory reaction and amebic trophozoites were found in brain biopsies. At autopsy, areas of hemorrhagic encephalomalacia were located in both basal frontal lobes, right parieto-occipital lobes, and, less often, in the brainstem and cerebellum. Angiitis, necrotizing granulomatous encephalitis, and large numbers of amebic trophozoites in perivascular spaces were present. Amebic trophozoites were seen in the left adrenal gland in one of the cases. The amebas in all four cases were identified as Balamuthia mandrillaris (Leptomyxiidae) based on their reactivity with the anti-Balamuthia (Leptomyxiidae) serum in an immunofluorescence test.

Reports on simultaneous central and peripheral nervous system involvement in a patient with brucellosis are very rare. We report of one young female patient with a long history of consumption of non-pasteurized dairy products in which clinical and laboratory findings confirmed the existence of an active brucellosis with nervous system impairment. Cerebrospinal fluid (CSF) analyses were negative. Electrophysiology and positive findings on sural nerve biopsy complemented the diagnosis of polyneuroradiculomyeloencephalitis. Treatment with a combination of doxycycline and rifampin for 2 months was successfully applied. No relapse or sequelae occurred in the patient after 12 months of follow up.

Serum of normal volunteers and serum of epileptic patients receiving either a single drug or combined antiepileptic therapy with Phenytoin (Phen); Carbamazepine (Cbz); Primidone (Prim); Phenobarbital (Phb) were examined and showed: No differences with regard to total proteins, albumins and A/G ratio. The alpha 1-globulin fraction increased to 4.4% with Phen/Cbz (P less than 0.001) and decreased to 1.7% with Phen/Prim = (P less than 0.001). The alpha 2-globulins corresponded to 7.2% (P less than 0.001) with Phen/Prim and 15.5% (P less than 0.001) with Phen/Phb treatments. beta-Globulins decreased to 7.1% (P less than 0.05) when received Phen/Phb treatment. Low concentrations of serum gamma-Globulins were found in Phb (P less than 0.001), Prim (P less than 0.001, Phen (P less than 0.001) treated patients. However, with Cbz, Phen/Phb, Phen/Prim this electrophoretic fraction remained within the upper range of normal. IgA of patients treated with Phen showed a mean of 60 mg/dl. Those patients with Phen serum levels below or above 12-20 micrograms/ml remained normal. Prim and Phb treatment also decreased IgA. IgD was normal in patients treated with Phen/Prim. Alterations of immune humoral responses to all antiepileptic drugs were found.

An evaluation of serum protein and immunoglobulins with regard to valproic acid (VPA) and phenytoin (phen) serum levels was performed in 28 epileptic patients. Serum antiepileptic levels were measured in fasting conditions. All patients were classified into the following groups: A (VPA below 50 micrograms/ml), B (VPA 50-89 micrograms/ml), C (VPA above 89 micrograms/ml), D (VPA 50-89 micrograms/ml and phen below 10 micrograms/ml). Patients of group C showed higher serum protein values than groups A (P less than 0.02), B and D (P less than 0.001). The alpha 2 and beta-globulin fractions were higher in group C than the remaining groups (P less than 0.05). Immunoglobulin A, G and M remained unaltered in all patients.
