RESUMO
INTRODUCTION: Pediatric epilepsy surgery is an effective treatment modality for patients with drug-resistant epilepsy (DRE). Early pediatric surgery yields favorable results for DRE in terms of seizure control and neurophysiological outcome. In this study, pediatric patients were categorized based on their age (above 3 years old and below 3 years old) to demonstrate the effectiveness and safety of surgical procedures. METHODS: In this retrospective, single-center study, 60 pediatric patients who underwent epilepsy surgery at Istanbul Faculty of Medicine between 2002 and 2018 were evaluated. Overall morbidity and mortality rates, as well as seizure outcomes of the patients, were assessed and compared based on two age groups: those aged 3 years old or younger and those older than 3 years old. The effectiveness of invasive monitoring was also evaluated in relation to pathological results. The postoperative seizure outcome rates were evaluated using Engel's classification, with an average follow-up period of 8.7 years. RESULTS: Out of the total number of patients, 47 (78.4%) underwent resective surgery, while 13 (21.6%) had palliative surgery. Ten patients (16.6%) had invasive monitoring. Among all patients, 34 were classified as Engel I and II (56.6%), while 26 were classified as Engel III and IV (43.4%) postoperatively. 47% of patients who were under 3 years old, 60.4% of patients who were over 3 years old, and 50% of patients who underwent invasive monitoring had a favorable seizure outcome (Engel I-II). Postoperative morbidity and mortality rates were 35% (n = 21) and 1.6% (n = 1), respectively. CONCLUSION: Pediatric epilepsy surgery is an important treatment modality for preserving cognitive abilities and providing effective treatment for pediatric DRE. In our study, we claim that both invasive monitoring and epilepsy surgery lead to favorable seizure outcomes for all age groups. Further clinical studies should be conducted to provide more reliable data on the safety and effectiveness of the surgery, particularly in patients under the age of three.

BACKGROUND: Managing intracranial bleeding in patients with refractory immune thrombocytopenia is difficult. OBSERVATION: A 16-year-old female refractory to prednisolone, intravenous immunoglobulin, eltrombopag, and cyclosporin exhibited heavy menstrual bleeding requiring packed red blood cell transfusions. Autoimmune antibodies were detected, indicating of lupus, and hydroxychloroquine sulfate was administered. In month 6 following the diagnosis, the patient presented with intracranial hemorrhage. Splenic artery embolization promptly increased platelets, and the patient was discharged without any neurological sequela. In month 5 of embolization, the patient's platelet count continued to exceed 300,000/µL without any medical treatment. CONCLUSIONS: Splenic artery embolization is a life-saving procedure in refractory immune thrombocytopenia.

BACKGROUND: Juvenile dermatomyositis (JDM) is the most common subtype of idiopathic inflammatory myopathies in childhood. Gottron's papules, shawl sign, periorbital heliotrope rash, and periungual telengiectasis are characteristic skin findings of the disease. Besides characteristic skin involvement, some other skin findings, such as angioedema, may be seen prior or in the course of the disease. The presence of angioedema in JDM is emphasized in this report. CASE PRESENTATIONS: We present 2 unrelated girls, aged 2 (case 1) and 12 years (case 2), who had developed symmetrical weakness in the proximal muscles, muscle pain, elevated muscle enzymes and angioedema. Both cases had abnormal muscle magnetic resonance imaging findings, suggestive of inflammatory myositis. Muscle biopsy was performed only in case 1, and major histocompatibility complex-1 expression on myofibers was shown consistent with JDM. Cases were diagnosed as probable and definite JDM, respectively. Angioedema was prominent, particularly in the lips and extremities of both cases, without laboratory evidence of C1 inhibitor deficiency or capillary leak syndrome, and absence of family history. Mast cell-mediated, acquired angioedema was the most likely diagnosis. In both cases, skin and muscle findings improved significantly with steroid treatment. CONCLUSION: We suggest that angioedema may be among the characteristic skin findings in JDM, and may be included in subsequent definitions.

The mitochondrial pyruvate dehydrogenase enzyme complex (PDHC) plays an important role in aerobic energy metabolism and acid-base equilibrium. PDHC contains of 5 enzymes, 3 catalytic (E1, E2, E3) and 2 regulatory, as well as 3 cofactors and an additional protein (E3-binding protein) encoded by nuclear genes. The clinical presentation of PDHC deficiency ranges from fatal neonatal lactic acidosis to chronic neurologic dysfunction without lactic acidosis. Paroxysmal neurologic problems such as intermittent ataxia, episodic weakness, exercise-induced dystonia and recurrent demyelination may also be seen although they are rare. Here, we present an 8-year-old boy complaining of acute proximal muscle weakness of upper and lower extremities with normal mental status. He had a history of Guillain-Barré-like syndrome at the age of 2 years. Electrophysiologic studies showed sensorial polyneuropathy findings in the first attack and sensorimotor axonal polyneuropathy findings in the last attack. The genetic analysis revealed a previously reported hemizygote novel mutation of the PDHA1 gene (p.A353T/c.1057G > A), which encodes the E1α subunit of PDHC. Thiamine was ordered (15 mg/kg/day), dietary carbohydrates were restricted and clinical findings improved in a few weeks. This rare phenotype of PDHC deficiency is discussed.

BACKGROUND: Schilder's disease is a rare, subacute, or chronic demyelinating disorder that mainly affects children and generally shows a monophasic course. CASE: Here, we present three boys diagnosed with Schilder's disease, age at onset 10-14 years, and followed up for 4-8 years. All of them presented with headache, two with encephalopathy and vomiting, and one with diplopia and vertigo. Cranial magnetic resonance imaging (MRI) showed two large demyelinating lesions, asymmetric in two patients and symmetric in the other. They were treated with steroid therapy. There were no radiologic relapses after discontinuation of corticosteroid therapy in all patients, but clinical attack without objective clinical findings was observed in one patient. Mild memory deficits and decline in school performance were the only neurologic sequelae in two patients. Cranial MRI findings showed significant shrinkage, but persistent T2-weighted hyperintensity of white matter lesions and loss of ring contrast enhancement at the end of the steroid therapy. There were no differences between the radiologic findings at the end of the steroid therapy and subsequent follow-ups. CONCLUSION: Although Schilder's disease is considered to be a variant of MS, it behaves more like ADEM with its monophasic course, and low recurrence rates. Radiologic features include shrinkage of mass lesions after steroid therapy, but sequel lesions remain same at the subacute and chronic stage.
