Placing of sewing needles in the brain through the anterior fontanel is a rare entity. There are very few cases reported in literature. Most of them were asymptomatic, but some of them presented with seizure. We report here a 14-year-old boy, who was admitted to the Pediatric Neurology Department with a history of generalized tonic-clonic seizures due to sewing needle located in the frontal lobe.

Mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) is a common medically intractable epilepsy syndrome. Although pathogenesis of HS still remains highly controversial, genetics may play a role as a predisposing factor. Previous evidence in a Japanese population revealed that the homozygotes for allele T at position −511 of the interleukin (IL)-1β gene promoter region (IL-1β-511 T/T) confers susceptibility to the development of HS. However, whether this polymorphism has an effect on IL-1β levels in MTLE-HS patients was not demonstrated. This study aimed to analyze the distribution of this particular polymorphism in a group of Turkish HS patients and correlate the polymorphism with IL-1β secretion from the lymphocytes, thus revealing a functional role for IL-1β in the etiopathogenesis of HS. A single base pair polymorphism at position −511 in the promoter region of the IL-1β gene was analyzed. The spontaneous and 1 ng/mL lipopolysaccharide-stimulated production of IL-1β by peripheral blood mononuclear cells after 4 and 24 h of incubation were measured by ELISA method. The heterozygous type (−511 C/T) was the most common genotype. There was no difference in frequency of allele −511 T between patients and controls. Analysis of IL-1β levels, genotype and allele distributions showed no significant difference among the groups (P>0.05). Nevertheless, it was seen that patients who carry a T allele at position -511 of the IL-1β gene had increased IL-1β levels. T-allele carriage may be important. Only IL-1β secretion from the lymphocytes has been assessed in this study. Considering the importance of IL-1β in the etiopathogenesis of HS, further studies are needed to evaluate locally produced IL-1β levels.

Central neurogenic hyperventilation (CNH) is a rare clinical condition, whose mechanism is still unclear. Here, we report a 3-year-old male patient, who had bilateral thalamic, putaminal and globus pallideal infarction resulted in CNH without brainstem involvement. This case may illustrate a possible role for the thalamus in regulating ventilation.

Purpose The aim of this study was to determine the clinical, laboratory, and radiological factors related with posttraumatic epilepsy (PTE). Methods The study is a multicenter descriptive cross-sectional cohort study. Children who followed up for TBI in the pediatric intensive care unit between 2014 and 2021 were included. Demographic data and clinical and radiological parameters were recorded from electronic case forms. All patients who were in the 6-month posttraumatic period were evaluated by a neurologist for PTE. Results Four hundred seventy-seven patients were included. The median age at the time of trauma was 66 (IQR 27–122) months, and 298 (62.5%) were male. Two hundred eighty (58.7%) patients had multiple traumas. The mortality rate was 11.7%. The mean duration of hospitalization, pediatric intensive care unit hospitalization and mechanical ventilation, Rotterdam score, PRISM III score, and GCS at admission were higher in patients with epilepsy ( p  < 0.05). The rate of epilepsy was higher in patients with severe TBI, cerebral edema on tomography and clinical findings of increased intracranial pressure, blood transfusion in the intensive care unit, multiple intracranial hemorrhages, and intubated patients ( p  < 0.05). In logistic regression analysis, the presence of intracranial hemorrhage in more than one compartment of the brain (OR 6.13, 95%CI 3.05–12.33) and the presence of seizures (OR 9.75, 95%CI 4.80–19.83) were independently significant in terms of the development of epilepsy ( p  < 0.001). Conclusions In this multicenter cross-sectional study, intracranial hemorrhages in more than one compartment and clinical seizures during intensive care unit admission were found to be independent risk factors for PTE development in pediatric intensive care unit patients with TBI.

The two polymorphisms [IL-12 (-1188) A/C and the IFN-γ (+874) A/T)] are known to have functional consequences and henceforth were analyzed in subacute sclerosing panencephalitis (SSPE) patients to reveal a possible relation with these polymorphisms and this debilitating disease. For the IL-12 (-1188) A/C polymorphism, 78 patients and 90 healthy individuals were analyzed. An increase in the AA genotype was determined ( p  = 0.02, OR = 2.06). There was also a statistically significant difference between the control group and the patients with respect to the allele frequencies ( p  = 0.04, OR = 1.65). For the IFN-γ (+874) A/T polymorphism, 69 SSPE patients and 115 controls were studied and there was not a significant difference between the two groups. Our findings suggested that not the IFN-γ (+874) A/T but the IL-12 (-1188) A/C polymorphism is correlated with SSPE and having an AA genotype or A allele decreases the risk of developing SSPE by 2.06- and 1.65-fold, respectively.

Background: Vitamin B12 deficiency occurs primarily as a result of insufficient dietary intake in children in developing countries. Vitamin B12 deficiency produces a cluster of neurological symptoms in children. Aim: The aim of this study was to describe the vitamin B12 status of patients who were admitted with neurological symptoms and to evaluate the clinical response to vitamin B12 treatment. Materials and Methods: This study was conducted on children who had vitamin B12 deficiency presented with neurological findings from January 2014 to October 2016. Patients with serum vitamin B12 levels lower than 300 pg/mL received intramuscular or oral vitamin B12 treatment. Results: Three hundred and fifty-one patients presenting with neurologic symptoms and who had low serum vitamin B12 deficiency were analyzed. Our study population was composed mainly of adolescent age. The most common symptom with respect to age was headache. In infant patients, most common symptoms were seizure and developmental delay. Conclusion: Early diagnosis and vitamin B12 treatment are advocated to avoid long-term injury. Our study shows that patients with serum vitamin B12 levels lower than 300 pg/mL showed clinical improvement of neurological symptoms after receiving vitamin B12 treatment.

Discussion Atlanto-axial rotatory subluxation is most commonly reported in patients with trauma, rheumatoid arthritis, ankylosing spondylitis, connective tissue disorders such as Marfan or Ehler Danlos Syndrome, Down syndrome, Lesch Nyan Syndrome, local inflammation or idiopathic [6-12]. [...]it still might be a co-incidence in our patient.

•Capillary hemangiomas in the spinal epidural area are extremely rare.•Only seven cases of capillary hemangioma have been reported in the English literature, and all of these occurred in adulthood.•Our study describes the youngest patient in the literature. Hemangiomas in the spinal epidural area are very rare lesions, and most of these lesions are of the cavernous type. Only seven cases of capillary hemangiomas have been reported in the English literature, and all of these cases occurred in adulthood. Here, we report on a 17-month-old girl who presented with an inability to walk. MRI revealed an epidural mass, which was diagnosed as an epidural capillary hemangioma in the thoracic region. To our best knowledge, this case is the first epidural capillary hemangioma case to occur in childhood that has been reported.

Melatonin, a major photoperiod-dependent hormone, regulates circadian rhythms and biological rhythms and acts as a prominent sleep promoter. Symptoms related to hypermelatoninemia have been reported in individuals supplemented with melatonin. However, spontaneous endogenous hypermelatoninemia has not been reported previously. A 6-year-old girl previously diagnosed with Shapiro’s syndrome was admitted to our hospital on several occasions during a 1-year period with complaints of altered consciousness, syncope, hypothermia and episodes of sweating. The episodes occurred daily and during sleep and lasted for 1–6 h. During these episodes, she sweated profusely and felt faint and her skin was pale and cool. Other complaints included recurrent abdominal pain, urge incontinence and myopia. She was shown to have hypermelatoninemia (>1,000 pg/ml, normal range 0–150 pg/ml) during these episodes. The duration of her attacks decreased with phototherapy and she was successfully treated with propranolol. To our knowledge, this is the first case of hypermelatoninemia without any detectable organic pathology. We did not determine the exact mechanism of hypermelatoninemia in this patient; however, it might have been related to irregular control of pinealocytes by the suprachiasmatic nucleus or related pathways. Hypermelatoninemia should be considered in patients with spontaneous periodic hypothermia and hyperhidrosis, and also in patients with Shapiro’s syndrome.
