Journal of Veterinary Science 2023;24(4):e59-
Background:
Rocuronium bromide has been evaluated as a mydriatic agent in birds, but the species applied were limited and the dose and effect were variable.
Objective:
This study aims to evaluate the efficacy of topical rocuronium bromide as mydriatics in 4 species according to horizontal palpebral fissure length: Feral pigeon (Columba livia), Common kestrel (Falco tinnunculus), Northern boobook (Ninox japonica), and Eurasian eagle owl (Bubo bubo).
Methods:
A total of 32 birds (8 for each species) were included as pre-releasing examination. Rocuronium bromide was instilled in one randomly selected eye of each bird based on palpebral fissure length criteria (0.5 mg/50 µL for pigeons, 1 mg/100 µL for kestrels and boobook owls, and 2 mg/200 µL for eagle owls). The contralateral eye was used as control and treated with normal saline. After instillation of the drug, pupil diameter, pupillary light reflex, intraocular pressure, heart rate, and respiratory rate were evaluated at 10 min intervals up to 180 min and at 30 min intervals up to 360 min.
Results:
Statistically significant mydriasis was obtained in all birds (p < 0.001). However, in boobook and eagle owls, marked mydriasis persisted until 360 min. Side effects including corneal erosion and lower eyelid paralysis were common, which was observed in 26/32 birds.Blepharospasm was also noted during this study. No systemic adverse signs were observed.
Conclusions
Rocuronium bromide could be a good mydriatics option for 4 species of birds, however, further studies are needed to find lowest effective dose to reduce drug-related side effects.
3.Effects of Lamotrigine on Problem-Solving Abilities in Newly Diagnosed Pediatric Patients with Epilepsy
Journal of Clinical Neurology 2020;16(1):46-52
BACKGROUND:
AND PURPOSE: This study aimed to determine the effects of lamotrigine (LTG) on language unction, including problem-solving abilities, in newly diagnosed pediatric epileptic patients.
METHODS:
This study included 112 newly diagnosed epileptic patients treated with LTG [69 males and 43 females aged 9.6±2.7 years (mean±SD)]. Repeated neurologic examinations, electroencephalography, neuroimaging studies, and standard language tests including the Test of Problem Solving (TOPS), mean length of utterance in words (MLU-w), Receptive and Expressive Vocabulary Test (REVT), and Urimal Test of Articulation and Phonology were performed before and after initiating LTG treatment. The starting LTG dosage was 1 mg/kg/day (maximum: 25 mg/day) for the first 14 days, which was increased to 2 mg/kg/day for the subsequent 14 days and then up to 7 mg/kg/day (or 200 mg/day) for maintenance.
RESULTS:
Problem-solving skills as assessed by TOPS scores significantly improved after initiating LTG treatment (33.5±14.5 vs. 35.7±14.25, p < 0.01). Scores in the “determining causes†category (11.9±4.7 vs. 12.9±4.8, p < 0.01), “making inferences†category (12.9±6.2 vs. 13.6±6.0, p < 0.05), and “predicting†category (8.9±5.4 vs. 9.7±5.6, p < 0.01) significantly improved after LTG treatment. The MLU-w score did not decrease after LTG treatment (4.7±1.9 vs. 5.0±2.1). There was a significant improvement in receptive language function as assessed using the REVT score (9.4±3.4 years vs. 9.9±3.3 years, p < 0.01). Precise articulation also improved after initiating LTG treatment (97.8% vs. 98.5%).
CONCLUSIONS
Language function including problem-solving skills improved after LTG treatment, suggesting that LTG can be administered without causing significant negative effects on language function in pediatric patients.

The aim of this study was to investigate the usefulness of a clinical screening test [the Korean Infant and Child Developmental Test (KICDT)] compared to language specific tests: the sequenced language scale for infant (SELSI) and the Preschool Receptive-Expressive language Scale (PRES) in children with delayed language development. A retrospective chart review was conducted on 615 children who visited the Department of Pediatrics at Chonbuk National University Hospital from January 2013 to December 2016. All patients were evaluated with KICDT as a clinical screening test and SELSI or PRES as a language specific test. Language Developmental Quotients (LDQs) from the KICDT were compared with the Receptive Language Quotient (RLQ) and expressive language quotient (ELQ) from the SELSI or PRES. The sensitivity, specificity and predictive values of LDQ of KICDT were calculated by comparing with SELSI/PRES. Language DQs from the KICDT were significantly correlated with the RLQ (r=0.706), ELQ (r=0.768), and total language quotient (TLQ) (r=0.766) from the SELSI/PRES (p<0.05). In cross tabulation, the patients belonging to the retardation groups in both KICDT and SELSI/PRES were 417 (67.8%). Otherwise, patients belonging to the normal group in KICDT but not in SELSI/PRES were 151 (24.6%). Sensitivity and specificity of LDQ of KICDT relative to SELSI/PRES were 72.3% and 92.2% respectively (p<0.05). Our data suggests that clinical screening tests alone, not cumbersome language specific tests, can determine language developmental delays in children.

BACKGROUND AND PURPOSE: The susceptibility-weighted imaging form of brain MRI using minimum intensity projection (mIP) is useful for assessing traumatic brain injuries because it readily reveals deoxyhemoglobin or paramagnetic compounds. We investigated the efficacy of using this methodology in nontraumatic patients. METHODS: We retrospectively analyzed the asymmetric mIP findings in nontraumatic patients. Asymmetric mIP images were first verified visually and then using ImageJ software. We enrolled patients with a difference of >5% between hemispheres in ImageJ analysis. All patients underwent detailed history-taking and EEG, and asymmetric mIP findings were compared. RESULTS: The visual analysis identified 54 pediatric patients (37 males and 17 females) with asymmetric mIP findings. Ten patients were excluded because they did not meet the ImageJ verification criteria. The 44 patients with asymmetry comprised 36 with epilepsy, 6 with headache, and 2 with cerebral infarction. Thirty-one of the 36 epileptic patients showed definite partial seizure activities in semiology, while the remaining patients did not demonstrate a history of partial seizure manifestations. The MRI findings were normal in all patients except for five with periventricular leukomalacia unrelated to seizure symptoms. There was agreement between mIP images and semiology in 29 (93.5%) of the 31 epileptic patients with focal signs, while the other 2 demonstrated discordance. Twenty (64.5%) of the 31 patients showed consistent EEG abnormalities. CONCLUSIONS: Our data suggest that asymmetric mIP findings are an excellent lateralizing indicator in pediatric patients with partial epilepsy.

Although foreign body ingestion is relatively common in children aged 6 months-3 years, small bowel obstruction rarely develops, and few cases require surgical interventions. We report a case of 12-month-old girl who presented to the emergency department with new-onset seizure after projectile bilious vomiting. The initial diagnosis was seizure caused by hyponatremia based on laboratory findings, plain abdominal radiograph, brain magnetic resonance imaging, and electroencephalography. Despite fluid resuscitation, clinical manifestations did not improve, and severe ileal obstruction was found on computed tomography. Emergency laparoscopy showed a foreign body (a water bead [superabsorbent polymer], 3 cm in diameter) that was subsequently removed by enterotomy. After the surgery, bilious vomiting continued, and gastrografin did not pass on fluoroscopy. The second laparoscopy showed a residual foreign body that was crushed and then removed by minimal enterotomy. She was discharged in good condition 5 days after the second surgery. This case suggests a particular danger of water beads as foreign bodies and the need for differential diagnosis of multiple foreign bodies in children with poor communication skills.

7.A Case Report of Precocious Puberty in Children Associated with Hypothalamic Hamartoma in Neurofibromatosis Type 1.
Shin Ae LEE ; Jin Ho KIM ; Sun Jun KIM
Journal of the Korean Child Neurology Society 2018;26(1):48-51
Neurofibromatosis type 1 (NF1) is a common neurocutaneous syndrome that presents with multiple café-au-lait spots, skinfold freckling, dermatofibromas, neurofibromas, and Lisch nodules. Mutations of the NF1 gene, encoding the protein neurofibromin, have been identified as the cause of this disease. NF1 can also present with precocious puberty and be associated with optic pathway tumors. Hypothalamic hamartoma as the cause of precocious puberty in patients with NF1 has been rarely described in the literature. Here, we report the findings for a patient with NF1 and precocious puberty associated with a hypothalamic hamartoma who had a newly discovered 14-bp deletion mutation in exon 5 of NF1. To our knowledge, this is the first time this combination is reported in the literature.

8.Effects of Antiepileptic Drugs on Language Abilities in Benign Epilepsy of Childhood with Centrotemporal Spikes.
Journal of Clinical Neurology 2018;14(4):523-529
BACKGROUND AND PURPOSE: This study is to assess the responsiveness of electroencephalography (EEG) abnormalities and their effects on language ability after initiating different types of antiepileptic therapy in children with newly diagnosed benign epilepsy of childhood with centrotemporal spikes (BECTS). METHODS: The records of patients newly diagnosed with BECTS (n=120; 69 males) were reviewed retrospectively. The patients were randomly treated with lamotrigine, oxcarbazepine, or topiramate monotherapy, and underwent at least two EEG and standardized language tests. Effects were compared using Pearson’s chi-square tests and paired t-tests. RESULTS: The recurrence rates for seizures in the lamotrigine, topiramate, and oxcarbazepine groups were 19.4%, 21.7%, and 11.4%, respectively, while complete or partial recovery (as indicated by EEG) occurred in 32%, 39%, and 16% of the patients. Patients in the lamotrigine group showed significant improvements in all parameters assessed by the Test of Language Problem Solving Abilities, except for ‘determining cause.’ Patients in the oxcarbazepine group also showed improvements, except for ‘making inferences’ (p < 0.05). Most linguistic index scores were worse in the topiramate group except for Mean Length of Utterance in Words. Patients in the lamotrigine and oxcarbazepine groups showed significant improvements in the receptive language test (p < 0.05). EEG improvements were not related to language ability. CONCLUSIONS: The improvements in language and problem-solving performance in children with BECTS were greater for lamotrigine and oxcarbazepine than for topiramate. However, EEG remission did not imply that language function would be improved after the treatments.

Korean Journal of Pediatrics 2018;61(12):387-391
PURPOSE: Subgaleal hemorrhage (SGH) is a rare but potentially fatal condition in newborns; however, few studies have reported on this condition. We aimed to identify the clinical characteristics and prognostic factors of SGH. METHODS: We retrospectively reviewed the medical records of 20 neonates diagnosed with SGH between January 2000 and June 2017. Enrolled neonates were clinically diagnosed when they had tender fluctuant scalp swelling that crossed the suture lines. RESULTS: Among 20 neonates with SGH, 12 were boys and 7 were girls; median hospitalization duration was 9.7±6.9 days. Fourteen neonates (70%) were born via vacuum-assisted vaginal delivery, and 4 via vacuum-assisted cesarean section. Of the neonates enrolled, half of them initially showed unstable vital signs, including apnea, desaturation, and cyanosis. Ten neonates had acidosis and 3 had asphyxia (pH < 7.0). Intracranial lesions associated with SGH were observed in 15 neonates (75%), including subdural hemorrhage (50%), subarachnoid hemorrhage (15%), intraventricular hemorrhage (5%), cerebral infarct (15%), skull fracture (30%), and cephalohematoma (20%). Twelve neonates (60%) required transfusion, 5 (25%) had seizures, and 3 (15%) died. Eight neonates (40%) had hyperbilirubinemia (mean total bilirubin, 13.1±7.4). The mean follow-up period was 8.4±7.5 months. At follow-up, 10 neonates (58.8%) were healthy with normal development, whereas 7 (41.2%) had neurological deficits. CONCLUSION: The morbidity rate was 41.2% due to severe metabolic acidosis. Anemia, hyperbilirubinemia, low Apgar scores, and subdural hemorrhage did not affect the prognosis. The long-term outcomes of neonates with SGH are generally good. Only arterial blood pH was significantly associated with death.

Korean Journal of Pediatrics 2017;60(7):227-231
PURPOSE: This study aimed to verify the safety of low-dose topiramate on language development in pediatric patients with migraine. METHODS: Thirty newly diagnosed pediatric patients with migraine who needed topiramate were enrolled and assessed twice with standard language tests, including the Test of Language Problem Solving Abilities (TOPs), Receptive and Expressive Vocabulary Test, Urimal Test of Articulation and Phonology, and computerized speech laboratory analysis. Data were collected before treatment, and topiramate as monotherapy was sustained for at least 3 months. The mean follow-up period was 4.3±2.7 months. The mean topiramate dosage was 0.9 mg/kg/day. RESULTS: The patient's mean age was 144.1±42.3 months (male-to-female ratio, 9:21). The values of all the language parameters of the TOPs were not changed significantly after the topiramate treatment as follows: Determine cause, from 15.0±4.4 to 15.4±4.8 (P>0.05); making inference, from 17.6±5.6 to 17.5±6.6 (P>0.05); predicting, from 11.5±4.5 to 12.3±4.0 (P>0.05); and total TOPs score, from 44.1± 13.4 to 45.3±13.6 (P>0.05). The total mean length of utterance in words during the test decreased from 44.1±13.4 to 45.3±13.6 (P<0.05). The Receptive and Expressive Vocabulary Test results decreased from 97.7±22.1 to 96.3±19.9 months, and from 81.8±23.4 to 82.3±25.4 months, respectively (P>0.05). In the articulation and phonology validation in both groups, speech pitch and energy were not significant, and all the vowel test results showed no other significant values. CONCLUSION: No significant difference was found in the language-speaking ability between the patients; however, the number of vocabularies used decreased. Therefore, topiramate should be used cautiously for children with migraine.
