Clinical and laboratory findings and etiologies of genetic homocystinemia: a single-center experience.

Background: Homocysteine (Hcy) is an endogenous nonprotein sulfur-containing amino acid biosynthesized from methionine by the removal of its terminal methyl group. Hyperhomocysteinemia (HHcy) has been linked to many systemic disorders, including stroke, proteinuria, epilepsy, psychosis, diabetes, lung disease, and liver disease. The clinical effects of high serum Hcy level, also known as hyperhomocysteinemia, have been explained by different mechanisms.

Evaluation of nutritional status in pediatric intensive care unit patients: the results of a multicenter, prospective study in Turkey.

Introduction: Malnutrition is defined as a pathological condition arising from deficient or imbalanced intake of nutritional elements. Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies.

The Effects of Protein Intake on Clinical Outcome in Pediatric Intensive Care Units.

Objective: Factors such as increased metabolic needs and inadequate calorie and protein intake increase the risk of malnutrition in critically ill children admitted to the pediatric intensive care unit. This study aimed to determine the risk of malnutrition and associated clinical outcomes.

Materials And Methods: Data from all patients aged 1 month to 18 years in 4 pediatric intensive care units in Adana, Turkey, were prospectively collected.

The Role of Therapeutic Plasma Exchange in the Treatment of Childhood Intoxication: A Single-Center Experience.

Objectives: Therapeutic plasma exchange is used to treat neurologic, hematological, renal, and autoimmune diseases with a known or suspected etiopathogenesis. However, there is incomplete understanding of the use of therapeutic plasma exchange in pediatric cases of intoxication. This study investigated 5 years of experience with therapeutic plasma exchange to treat intoxication cases.

Correction to: Overview of therapeutic plasma exchange in pediatric neurology: a single-center experience.

Unfortunately, the immediate following sentences were incorrectly published in Material and Method section of the original article.

Overview of therapeutic plasma exchange in pediatric neurology: a single-center experience.

Therapeutic plasma exchange (TPE) is used in the treatment of neurological, hematological, renal and autoimmune diseases with known or suspected immune pathogenesis. In comparison with neurological diseases of adults, knowledge about the use of TPE in children is incomplete. We report our experience on TPE in children with neurological diseases in a single institution and describe the underlying etiology, clinical course, treatment and outcome.

Sadfly fever: two case reports.

Sandfly fever, also known as 'three-day fever' or 'pappataci fever' or 'Phlebotomus fever' is a viral infection that causes self-limited influenza-like symptoms and characterized by a rapid onset. The disease occurs commonly in endemic areas in summer months and especially in August during which sandflies are active. In this article, two siblings who presented with high fever, redness in the eyes, headache, weakness, malaise and inability to walk, who were found to have increased liver function tests and creatine kinase levels and who were diagnosed with sadfly fever with positive sadfly IgM and IgG antibodies are reported because of the rarity of this disease.

Optic neuritis as a presenting symptom of Mycoplasma pneumoniae infection.

A broad range of neurologic disorders has been described in children infected with Mycoplasma pneumoniae, of which encephalitis is among the most common. In contrast, the association between optic neuritis and Mycoplasma pneumoniae infection has been rarely described in children. We report a case of a 12-year-old girl who was seropositive for antibodies against Mycoplasma pneumoniae and presented with optic neuritis without respiratory symptoms or other neurologic findings.

Serum vitamin B12, folic acid, and homocysteine levels in children with febrile seizure.

The aim of this study is to investigate the associations between febrile seizure and serum levels of vitamin B12, folic acid, and homocysteine. One hundred and four children who presented with febrile seizure and 75 controls who presented with febrile illness unaccompanied by seizure were enrolled into the study. Mean levels of vitamin B12, folic acid and homocysteine were compared between two groups.

Efficacy of topical 0.05% cyclosporine treatment in children with severe vernal keratoconjunctivitis.

We aimed to determine the efficacy of topical cyclosporine in children with vernal keratoconjunctivitis refractory to topical mast cell stabilizer and antihistamine therapy. Thirty-one patients, 24 boys and 7 girls younger than 16 years of age, were included in the study. All patients were scored on a four-point scale from 0 to 3 for symptoms and signs.

Congenital segmental spinal muscular atrophy: a case report.

Spinal muscular atrophies are genetic disorders in which anterior horn cells in the spinal cord and motor nuclei of the brainstem are progressively lost. We present a patient with arthrogryposis due to congenital spinal muscular atrophy predominantly affecting the upper limbs. Spinal muscular atrophies with onset at birth may be a cause of arthrogryposis.

Overview of pediatric peripheral facial nerve paralysis: analysis of 40 patients.

Peripheral facial nerve paralysis in children might be an alarming sign of serious disease such as malignancy, systemic disease, congenital anomalies, trauma, infection, middle ear surgery, and hypertension. The cases of 40 consecutive children and adolescents who were diagnosed with peripheral facial nerve paralysis at Baskent University Adana Hospital Pediatrics and Pediatric Neurology Unit between January 2010 and January 2013 were retrospectively evaluated. We determined that the most common cause was Bell palsy, followed by infection, tumor lesion, and suspected chemotherapy toxicity.

Tic disorder probably associated with steroid responsive encephalopathy with autoimmune thyroiditis (SREAT).

Steroid responsive encephalopathy with autoimmune thyroiditis (SREAT), a rare disorder in individuals of all age groups, including children, is characterized by high titers of anti-thyroid peroxidase antibodies. The present report concerns a previously healthy 12-y-old boy who presented with motor tics. The patient underwent an extensive work-up to identify the underlying etiologies and risk factors predisposing him to tic disorder.

Association between hypocapnia and febrile seizures.

The purpose of this study is to determine whether hyperthermia-induced hyperventilation with subsequent hypocapnia is relevant to febrile seizures in children. This is only the second study to measure pCO2 and pH values in children with febrile seizures. This prospective case-control study enrolled 18 children who presented with febrile seizures and 18 children who presented with a febrile illness without seizures.

Central retinal artery occlusion in a 13-year-old child as a presenting sign of hyperhomocysteinemia together with high lipoprotein(a) level.

Background: We describe a child with central retinal artery occlusion and hyperhomocysteinemia.

Methods: A 13-year-old girl developed sudden vision loss and was hospitalized for diagnosis and treatment.

Results: Her physical examination was normal except for her ophthalmologic examination.

Acute disseminated encephalomyelitis in children and adolescents: a single center experience.

Background: Acute disseminated encephalomyelitis is an immune-mediated disease that produces multiple inflammatory lesions in the brain and spinal cord.

Methods: This study retrospectively evaluated 15 children with acute disseminated encephalomyelitis in children and adolescents from a single institution in Adana, Turkey.

Results: The patients presented in a seasonal distribution, with 73.

Long-term accidental overdose of levetiracetam in an infant.

Levetiracetam is one of the new anticonvulsant drugs that has a high therapeutic index and potential antiepileptogenic effects. Herein, we report a patient with multidrug refractory epilepsy and Ohtahara syndrome who was accidentally administered 300 mg/kg/d for 35 days by her mother. To our knowledge, there are only a few cases of accidental overdose of levetiracetam in pediatric patients reported in the literature, and this case study is the first to report such a high and long-term dose in an infant who showed no adverse effects.

Cerebellar mutism caused by primary varicella infection in an immunocompetent child.

Varicella (chickenpox) is a common childhood infection caused by the varicella-zoster virus, which is often self-limiting and usually benign. Although uncommon, neurologic complications of varicella have been documented that include postinfectious cerebellar ataxia, meningoencephalitis, Reye syndrome, myelitis, optic neuritis, stroke, Guillain-Barré syndrome, seventh cranial nerve palsy, and Ramsay-Hunt syndrome. In this case study, the authors describe a 7-year-old girl who presented with varicella skin rash with unsteady gait and anarthria on day 2, and her condition was attributed to cerebellar mutism.

Vici syndrome associated with sensorineural hearing loss and laryngomalacia.

The phenotypically heterogeneous, autosomal recessive Vici syndrome was first described in 1988 in a sister and brother with oculocutaneous albinism, agenesis of the corpus callosum, cataract, cardiomyopathy, cleft lip, and immunodeficiency. Only 14 cases of Vici syndrome have yet been reported, several involving morphologic and functional defects in addition to those described in the initial case. We report on a 3-month-old Turkish girl with Vici syndrome associated with laryngomalacia, further expanding the clinical spectrum.

Acute disseminated encephalomyelitis associated with influenza A H1N1 infection.

Acute disseminated encephalomyelitis is an immune-mediated inflammatory disorder of the central nervous system, characterized by demyelination. Acute disseminated encephalomyelitis predominantly involves the white matter of the brain and spinal cord, and often follows upper respiratory tract infection. We describe a case of acute disseminated encephalomyelitis associated with the influenza A (H1N1) virus.
