RESUMEN Introducción: Entre las hamartoblastosis se reconoce el síndrome de Sturge-Weber (SSW), cuyo diagnóstico es inusual y complejo su tratamiento. Objetivo: Socializar la experiencia en la atención a un paciente pediátrico con síndrome de Sturge-Weber en el Hospital Pediátrico Docente "General Pedro Agustín Pérez" de Guantánamo. Método: Se presentó un paciente preescolar, sin antecedentes familiares de interés. Al mes de nacido fue operado de glaucoma congénito. Durante el primer año de vida presentó retardo del desarrollo psicomotor y movimientos involuntarios considerados convulsiones tónico-clónicas. Se revisó la literatura para transmitir a la comunidad médica, de modo particular, a estudiantes de medicina y médicos generales, información para lograr un diagnóstico y un seguimiento adecuado de esta afección. Resultados: Según las manifestaciones clínicas, examen físico mediante el método clínico y los resultados de los exámenes complementarios, se planteó el diagnóstico de síndrome neurocutáneo, de modo particular un SSW. Se aplicó tratamiento con diazepam y al persistir la crisis, fenitoína. La primera clasificación de los síndromes neurocutáneos la realizó Jan Van der Hoeve, que acuñó el término facomatosis. Es un trastorno neurológico congénito, no hereditario aunque hay descrito casos familiares, poco común pero frecuente respecto a otros síndromes neurocutáneos. Se estima una incidencia de 5 x 100,000 nacidos vivos. Afecta a todos los grupos étnicos y ambos sexos. Conclusiones: No siempre hay relación entre la gravedad de las manifestaciones cutáneas, neurológicas y oculares del SSW con las alteraciones cerebrales. Es importante el examen físico para establecer el diagnóstico oportuno y evitar futuras secuelas y complicaciones.

ABSTRACT Introduction: Sturge-Weber syndrome (SSW) is recognized among hamartoblastosis, whose diagnosis is unusual and complex treatment. Objective: To socialize the experience in the care of a pediatric patient with Sturge-Weber syndrome at the "General Pedro Agustín Pérez" Pediatric Teaching Hospital in Guantanamo. Method: A preschool patient was presented, with no family history of interest. One month after birth, he underwent congenital glaucoma surgery. During the first year of life he presented retardation of psychomotor development and involuntary movements considered tonic-clonic seizures. Literature was reviewed to transmit to the medical community, in particular, to medical students and general practitioners, information to achieve a diagnosis and adequate follow-up of this condition. Results: According to the clinical manifestations, physical examination by means of the clinical method and the results of the complementary examinations, the diagnosis of neurocutaneous syndrome was proposed, in particular a SSW. Treatment with diazepam was applied and when the crisis persisted, phenytoin. The first classification of neurocutaneous syndromes was carried out by Jan Van der Hoeve, who coined the term phacomatosis. It is a congenital neurological disorder, not inherited although there have been family cases described, uncommon but frequent compared to other neurocutaneous syndromes. An incidence of 5 x 100,000 live births is estimated. It affects all ethnic groups and both sexes. Conclusions: There is not always a relationship between the severity of cutaneous, neurological and ocular manifestations of SSW with brain disorders. The physical examination is important to establish the timely diagnosis and avoid future sequelae and complications.

RESUMO Introdução: A síndrome de Sturge-Weber (SSW) é reconhecida entre as hamartoblastose, cujo diagnóstico é tratamento incomum e complexo. Objetivo: Socializar a experiência no atendimento de um paciente pediátrico com síndrome de Sturge-Weber no Hospital Pediátrico "General Pedro Agustín Pérez" em Guantánamo. Método: Foi apresentado um paciente pré-escolar, sem histórico familiar de interesse. Um mês após o nascimento, ele foi submetido a uma cirurgia de glaucoma congênito. Durante o primeiro ano de vida, apresentou retardo no desenvolvimento psicomotor e movimentos involuntários considerados convulsões tônico-clônicas. A literatura foi revisada para transmitir à comunidade médica, em particular aos estudantes de medicina e clínicos gerais, informações para obter um diagnóstico e acompanhamento adequado dessa condição. Resultados: De acordo com as manifestações clínicas, o exame físico por meio do método clínico e os resultados dos exames complementares, foi proposto o diagnóstico de síndrome neurocutânea, em particular um SSW. O tratamento com diazepam foi aplicado e, quando a crise persistiu, fenitoína. A primeira classificação das síndromes neurocutâneas foi realizada por Jan Van der Hoeve, que cunhou o termo facomatose. É um distúrbio neurológico congênito, não herdado, embora haja casos familiares descritos, incomum, mas frequente em comparação com outras síndromes neurocutâneas. É estimada uma incidência de 5 x 100.000 nascidos vivos. Afeta todos os grupos étnicos e ambos os sexos. Conclusões: Nem sempre existe relação entre a gravidade das manifestações cutâneas, neurológicas e oculares da SSW com distúrbios cerebrais. O exame físico é importante para estabelecer o diagnóstico oportuno e evitar futuras sequelas e complicações.

The Pathogenesis of Port Wine Stain and Sturge Weber Syndrome: Complex Interactions between Genetic Alterations and Aberrant MAPK and PI3K Activation.

Port wine stain (PWS) is a congenital vascular malformation involving human skin. Approximately 15-20% of children a facial PWS involving the ophthalmic (V1) trigeminal dermatome are at risk for Sturge Weber syndrome (SWS), a neurocutaneous disorder with vascular malformations in the cerebral cortex on the same side of the facial PWS lesions. Recently, evidence has surfaced that advanced our understanding of the pathogenesis of PWS/SWS, including discoveries of somatic genetic mutations (GNAQ, PI3K), MAPK and PI3K aberrant activations, and molecular phenotypes of PWS endothelial cells. In this review, we summarize current knowledge on the etiology and pathology of PWS/SWS based on evidence that the activation of MAPK and/or PI3K contributes to the malformations, as well as potential futuristic treatment approaches targeting these aberrantly dysregulated signaling pathways. Current data support that: (1) PWS is a multifactorial malformation involving the entire physiological structure of human skin; (2) PWS should be pathoanatomically re-defined as "a malformation resulting from differentiation-impaired endothelial cells with a progressive dilatation of immature venule-like vasculatures"; (3) dysregulation of vascular MAPK and/or PI3K signaling during human embryonic development plays a part in the pathogenesis and progression of PWS/SWS; and (4) sporadic low frequency somatic mutations, such as GNAQ, PI3K, work as team players but not as a lone wolf, contributing to the development of vascular phenotypes. We also address many crucial questions yet to be answered in the future research investigations.

Glaucoma in Patients with Eyes Close to Areas Affected by Port-wine Stain has Lateral and Gender Predilection.

BACKGROUND: The location of facial port-wine stain (PWS) may be helpful for predicting some associated anomalies; high glaucoma incidence is found in patients with eyes close to PWS-affected areas (V1, ophthalmic branch area of the trigeminal nerve). This study aimed to investigate the characteristics of glaucoma in V1-affected PWS. METHODS: A total of 569 patients with V1 area-affected PWS were reviewed in the study. The large series was based on the referral system between the Department of Plastic and Reconstructive Surgery and the Department of Ophthalmology. All patients were screened for glaucoma with assessments of intraocular pressure, cup-to-disc ratio, corneal diameter (only for infants), and axial length. RESULTS: Of the 569 patients, 110 (19.3%) patients had glaucoma. Among the patients, 18.1% (76/420) had early-onset glaucoma (under 4-year-old group). In the 4 to 18-year-old age group, 29.3% (29/99) of the patients had glaucoma. Compared with right lateral and bilateral PWS, left-sided PWS had a lower risk of glaucoma in this study (odds ratio = 0.432 [95% confidence interval, 0.264-0.706], P = 0.01). The under 4-year-old group showed a slight predominance of males (61.8%) in glaucoma. CONCLUSIONS: High glaucoma incidence was observed in patients with eyes close to PWS. More attention should be paid to glaucoma screening for right lateral and bilateral PWS patients. The predominance of males in Sturge-Weber syndrome (SWS) early-onset glaucoma patients might be due to the limitation of the case number; however, it might also provide us a new clue of potential relationship between SWS and PCG.

Sturge Weber-Like Gyral Calcification Seen in Tuberous Sclerosis Complex 1.

A 10-year-old girl presented with poorly controlled epilepsy. On evaluation, she had microcephaly, neuro-cutaneous stigmata of tuberous sclerosis complex, profound mental retardation, and spastic hemiparesis. Computed tomography (CT) revealed a calcified subependymal nodule and extensive left gyral calcification of the temporal, parietal, and occipital regions with unilateral cerebral atrophy, radiologic features usually seen in Sturge Weber syndrome. Magnetic resonance imaging (MRI) revealed absence of tubers, enlarged choroid plexus, or leptomeningeal angiomas, thus excluding type 3 Sturge Weber syndrome. The genotype was a heterozygous mutation in exon 18 of the tuberous sclerosis type 1 gene (c.2293C>T p.Q765X). A comparison of previously reported 7 cases of Sturge Weber syndrome and tuberous sclerosis complex was made. This revealed 4 actual double phakomatoses (clinical, radiologic, or genetic phenotypes) and 3 cases with clinical phenotype of tuberous sclerosis and gyral calcifications within tubers simulating the radiologic picture of Sturge Weber syndrome.

Focal venous hypertension as a pathophysiologic mechanism for tissue hypertrophy, port-wine stains, the Sturge-Weber syndrome, and related disorders: proof of concept with novel hypothesis for underlying etiological cause (an American Ophthalmological Society thesis).

PURPOSE: To provide an in-depth re-examination of assumed causes of tissue hypertrophy, port-wine stains, and the Sturge-Weber, Cobb, Klippel-Trénaunay, and related syndromes to support an alternative unifying pathophysiologic mechanism of venous dysplasia producing focal venous hypertension with attendant tissue responses; to provide proof of concept with new patient data; to propose a novel etiological hypothesis for the venous dysplasia in these syndromes and find supportive evidence. METHODS: Data from 20 patients with port-wine stains and corneal pachymetry readings was collected prospectively by the author in an institutional referral-based practice. The literature was searched using MEDLINE, and articles and textbooks were obtained from the bibliographies of these publications. RESULTS: Newly obtained dermatologic, corneal pachymetry, fundus ophthalmoscopic, ocular and orbital venous Doppler ultrasonography, and magnetic resonance imaging findings in patients with the Sturge-Weber syndrome or isolated port-wine stains, along with published data, reveal diffusely thickened tissues and neural atrophy in all areas associated with venous congestion. CONCLUSIONS: Contrary to traditional understanding, signs and symptoms in the Sturge-Weber and related syndromes, including both congenital and acquired port-wine stains, are shown to arise from effects of localized primary venous dysplasia or acquired venous obstruction rather than neural dysfunction, differentiating these syndromes from actual phacomatoses. Effects of focal venous hypertension are transmitted to nearby areas via compensatory collateral venous channels in the above conditions, as in the Parkes Weber syndrome. A novel underlying etiology-prenatal venous thrombo-occlusion-is proposed to be responsible for the absence of veins with persistence and enlargement of collateral circulatory pathways with data in the literature backing this offshoot hypothesis. The mechanism for isolated pathologic tissue hypertrophy in these syndromes clarifies physiologic mechanisms for exercise-induced muscle hypertrophy to occur via venous compression and increased capillary transudation.

Pediatric functional hemispherectomy: outcome in 92 patients.

BACKGROUND: The revival of epilepsy surgery after the introduction of modern presurgical evaluation procedures has led to an increase in hemispherectomy or hemispherotomy procedures. Since a large part of our pediatric series was done using a newer hemispherotomy technique, we focus mainly on the outcomes after a recently developed hemispherotomy technique (transsylvian keyhole). METHODS: Ninety-six pediatric patients (aged 4 months to 18 years, mean 7.3) were operated on between 1990 and 2009; 92 were available with follow-up. RESULTS: The most frequent diagnosis was porencephaly in 46 % of all patients. Progressive etiologies were present in 20 % and developmental etiologies in 22 %. At last available outcome (LAO), 85 % of the patients were seizure free (ILAE class 1). Year-to-year outcome was rather stable; usually over 80 % were class 1 for up to 13 years (n = 24). Of 92 assessable patients, 71 were treated with the transsylvian keyhole technique, with 89 % being seizure free. The overall shunt rate was 5.3 % for the whole series and 3 % for the keyhole technique subgroup. Mortality was 1 of 96 patients. Excluding patients with hemimegalencephaly (HME), patients with the shortest duration of epilepsy and the lowest age at seizure onset had the highest rates of seizure freedom. The etiology does influence outcome, with HME patients having the poorest seizure outcome and patients with Sturge-Weber syndrome and porencephaly having excellent seizure control. CONCLUSION: Hemispherotomies/functional hemispherectomies are very effective and safe procedures for treating drug-resistant epilepsy with extensive unihemispheric pathology. Etiology and surgery type clearly influence seizure outcome.

Síndrome de Sturge-Weber e suas repercussões oculares: revisão da literatura / Sturge-Weber syndrome and its ocular effects: a review

A síndrome de Sturge-Weber (SSW) é uma desordem neuro-oculocutânea, rara e congênita. Esta facomatose, também conhecida como angiomatose encéfalotrigeminal, é definida pela tríade clássica: hemangiomas cutâneo, meníngeo e ocular. Apesar de sua apresentação típica, formas incompletas não são incomuns. O glaucoma está frequentemente presente e seus mecanismos fisiopatológicos permanecem incertos. Talvez por isso, o manejo clínico e cirúrgico do glaucoma associado à síndrome de Sturge-Weber (GSSW) seja um desafio para a prática oftalmológica, muitas vezes com resultados desapontadores. Apresentamos uma revisão da literatura com ênfase no GSSW, sua patogênese e perspectivas terapêuticas.

The Sturge-Weber syndrome (SWS) is a rare congenital neuro-oculocutaneous disorder. This phacomatosis, also known as encephalotrigeminal angiomatosis, is defined by the classic triad: cutaneous, meningeal and ocular hemangiomas. Despite its typical presentation, incomplete forms are not uncommon. Glaucoma is often present and their pathophysiological mechanisms remain uncertain. Pherhaps this is why the clinical and surgical management of glaucoma associated with Sturge-Weber syndrome (GSSW) is a challenge for the ophthalmic practice, often with disappointing results. We present a literature review with emphasis on GSSW, its pathogenesis and therapeutic perspectives.

Portal cavernomatous transformation leading to variceal hemorrhage in Sturge-Webber syndrome. A rare, but possible association.

UNLABELLED: Sturge-Weber syndrome is a rare disorder consisting of a port-wine nevus in the distribution of the ophthalmic branch of the trigeminal nerve and central nervous system malformations. Facial cutaneous vascular malformation, seizures, and glaucoma are among the most common symptoms and signs. The syndrome results from malformation of the cerebral vasculature located within the pia mater, most commonly over the occipital region. These malformations led to venous hypertension and subsequent hypoperfusion on the underlying cortex, causing chronic cerebral ischemia, atrophy, calcification and neurological deterioration. We describe 18-years-old young girl hospitalized for upper digestive hemorrhage that revealed a cavernomatous transformation of portal vein. At the same time, she presents extensive congenital, bilateral port wine stains on the face, epilepsy and glaucoma of the right eye. Computer tomography showed intracranial vascular abnormalities with calcifications, particularly in the right occipital lobe. The clinical presentation and imagistic assessment confirmed the diagnosis of Sturge-Weber syndrome associated with upper non-cirrhotic portal hypertension generated by a malformation of portal vein. CONCLUSIONS: Upper digestive hemorrhage is a quite rare eventuality in the Sturge-Webber syndrome. Moreover, portal tract malformations with cavernomatous transformation are exceptionally cited in the literature. Despite this rare association, abdominal investigation, as well as computed cranial tomography should be performed in all cases of children that present a facial cutaneous vascular malformation.

Sturge-Weber syndrome: A case study.

Sturge-Weber syndrome (SWS) is a rare, sporadic, progressive, congenital syndrome. In its complete trisymptomatic form, SWS is physically characterized by port-wine stains over the trigeminal area, leptomeningeal angiomas usually over the parieto-occipital region, and eye abnormalities. Clinical manifestation for infants with SWS depends on the affected organs, but can include seizures, mental retardation, and glaucoma. This article begins with a case presentation of an infant with SWS and then presents the etiology, embryology, pathophysiology, clinical presentation, management, and prognosis of SWS.

Sturge-Weber syndrome and paroxysmal hemiparesis: epilepsy or ischaemia?

Transient neurological deficits experienced by patients with Sturge-Weber syndrome can be caused by epilepsy, or may result from temporary ischaemia of the cortex underlying the vascular malformation. To show the difficulty in distinguishing seizures from ischaemic symptoms, two male children with episodes of acute unilateral weakness are presented here as well as a review of the literature. The first child presented at 2 years of age with a sudden increase in his pre-existing right hemiparesis accompanied by screaming. Ictal epileptiform activity was recorded at the moment of the attack, and subsequent seizures were controlled by adjustment of antiepileptic drug treatment. The second child presented at 4 years of age with attacks of vomiting and a coinciding increase in the pre-existing paresis of the left leg. Electroencephalogram (EEG) recording did not show ictal epileptiform activity. The origin was presumed to be vascular. Treatment with aspirin led to control of these transient ischaemic attacks. Ictal EEG is needed to differentiate between an epileptic and an ischaemic origin of transient focal deficit. Treatment with aspirin should be considered if an ischaemic origin cannot be excluded.

Síndrome de Sturge-Weber: revisão de literatura e relato de dois casos clínicos / Sturge-Weber syndrome: review of the literature and report two cases

A síndrome de Sturge-Weber (SSW) é uma alteração vascular neurocutânea rara, com manifestações sistêmicas e bucais. Suas características incluem nevo cutâneo na face, hiperplasias gengivais e hemangiomas intrabucais, angioma venoso nas leptomeninges e calcificações cerebrais ipsilaterais. Dois pacientes foram encaminhados ao Hospital Heliópolis - São Paulo/Brasil para avaliação e tratamento odontológico. Foram realizados procedimentos profiláticos, raspagens periodontais e procedimentos restauradores. Após o término do tratamento, com o controle da placa bacteriana, foi possível observar melhora das alterações intra-bucais. Neste trabalho foi realizada uma revisão da literatura da síndrome de Sturge-Weber, assim como propusemos relatar nossa experiência no tratamento e avaliação das alterações intra-bucais de dois pacientes portadores desta síndrome, atendidos no serviço de Diagnóstico Bucal do Hospital Heliópolis - São Paulo/SP

Predominance of brain tumors in an extended Li-Fraumeni (SBLA) kindred, including a case of Sturge-Weber syndrome.

BACKGROUND: Li-Fraumeni syndrome (LFS) is characterized by a plethora of cancers, most prominent of which is carcinoma of the breast followed by sarcomas, brain tumors, leukemia, lymphoma, lung carcinoma, and adrenocortical carcinoma (therefore, also referred to by the acronym SBLA syndrome). METHODS: The family reported herein was first described 2 decades ago. Now extensive follow-up has shown the predictable occurrence of these tumor types, in addition to an excess of brain tumors and the finding of Sturge-Weber syndrome (SWS) in an LFS-affected family member. RESULTS: A possible new feature of the disorder, suggestive of SWS, was identified in a patient in the direct genetic lineage. This patient had a rhabdomyosarcoma of the eyelid at age 29 months and at age 14 years was diagnosed with lymphoblastic lymphoma/acute lymphoblastic leukemia. A remarkable excess of brain tumors was identified in this family through this current update. The p53 germ-line mutation was not identified in any affected member of this family. CONCLUSIONS: To the authors' knowledge, this is the first example of SWS in the context of LFS. Brain tumors appear to be an important component of the tumor spectrum of LFS, as evidenced in this family.

Weber syndrome caused by intracerebral hemorrhage in a hemophiliac boy.

A rare occurrence of the Weber syndrome in childhood is reported. The patient was a 7-year-old hemophiliac with recurrent intracerebral bleeding into the right cerebral peduncle and pontine base. Left hemiparesis involving the face and tongue developed and was later accompanied by right oculomotor nerve palsy.

[Weber syndrome caused by Listeria abscess]. / Syndrome de Weber par abcès listérien.

A 63-year old diabetic man presented with left Weber's syndrome and meningitic syndrome. CSF examination showed moderate lymphocytic pleocytosis and elevated proteins with normal glucose content and sterile culture. Blood cultures yielded Listeria monocytogenes and the patient received ampicillin. While his neurological condition had partially improved, he died of heart failure. Several mesencephalic abscesses were found at autopsy.

[Sturge-Weber disease]. / Bolezn' Sterdzha--Vebera.

Morphological changes in the vascular malformations of pia mater and neighbouring parts of the brain surgically removed in 9 patients with Sturge-Weber syndrome were studied light- and electron-microscopically. On the basis of the results obtained the concept of Sturge-Weber syndrome pathogenesis is formulated. According to this concept the disease develops due to the brain hypoxia resulting from the long-lasting congestion in the pia mater with angiomatosis. Respectively, the surgical treatment of the disease is founded and the necessity of such a treatment at young age is outlined. The authors' own data on the nearest (up to one year) and remote (up to 15 years) results of such treatment are presented.
