ABSTRACT

Objective@#To evaluate the accuracy and quality of Korean videos associated with restless legs syndrome (RLS) on YouTube. @*Methods@#A YouTube search was performed on April 1, 2020 using the term “restless legs syndrome” in the Korean language. Two reviewers coded the source, content, and demographics of the included videos. Video quality was assessed using the modified DISCERN (mDISCERN) instrument. @*Results@#Among the 80 videos analyzed, 44 (55.0%) were reliable, and 36 (45.0%) were misleading. There was a trend toward a higher number of mean daily views in the misleading videos than in the reliable videos. Most of the misleading videos (72.2%) advocated complementary and alternative medicine as a primary treatment for RLS. Although the reliable videos had higher mDISCERN scores than the misleading videos, the overall quality of the reliable videos was low. @*Conclusion@#Many Korean videos regarding RLS on YouTube involve a risk of exposure to misinformation and are of unsatisfactory quality.

ABSTRACT

Background@#and Purpose The purpose of this study was to determine the effect of fludrocortisone in patients with pediatric vasovagal syncope (VVS). @*Methods@#This retrospective observational single-tertiary-center study based on chart reviews included 74 patients who were newly diagnosed with VVS in the head-up tilt-table test (HUTT). Some of the patients had been treated with fludrocortisone. All patients were assessed using a brain and cardiac workup before treatment to rule out the syncope being due to other causes, which resulted in seven of them being excluded: two for epilepsy and five for brain pathologies. The remaining 67 patients were analyzed. The effect of fludrocortisone was evaluated based on the results of a follow-up HUTT, with a response to the treatment considered to be present if there was a negative change at the follow-up HUTT. Univariate logistic regression were used for statistical analyses, with the criterion for significance being p<0.05. @*Results@#There were no significant differences in the characteristic of the patients between the no-medication (n=39) and fludrocortisone (n=28) groups, including age, sex, and duration of treatment. The recurrence rate of syncopal or presyncopal events was significantly lower in the fludrocortisone group (39.3%, 11 of 28) than in the no-medication group (64.1%, 25 of 39) (p=0.044), as was the rate of negative change at the follow-up HUTT: 57.1% (16 of 28) and 28.2% (11 of 39), respectively (p=0.017). @*Conclusions@#Our findings suggest that fludrocortisone is more effective than no medication in pediatric patients with VVS.

ABSTRACT

Objective: The objective was to evaluate the feasibility and safety of computed tomography (CT)-guided percutaneous irreversible electroporation (IRE) in porcine kidneys. Materials and Methods: Under CT guidance, two monopole probes were used to precisely puncture through the renal parenchyma into the renal hilum in nine anesthetized adult Bama miniature pigs. After which, IRE ablation was performed. Biochemical and pathological examinations were carried out 2 h, 2, 7, and 14 days after the procedure. Results: All procedures were performed successfully without any serious complications such as bleeding, infection, or death. All pigs survived until the end of the study. Pathological examinations showed that cells in the ablation area were dead within 2 days after the procedure, whereas the vascular endothelium showed only slight damage. After 2 days, endothelialization ensued and regrowth of smooth muscle cells was observed after 14 days. Hemogram tests indicated a transient increase but gradually returned to baseline levels 14 days after the procedure. Conclusion: IRE was essentially safe, however further studies on tumor ablation using several different animal models are needed

ABSTRACT

SUMMARY OBJECTIVE The purpose of our study was to confirm the relationship between low-intensity exercise and physical and mental health status among college students in China. METHODS This was a school-based cross-sectional study. The physical and mental health status was measured using a 12-item general health questionnaire(GHQ12) and low-intensity exercise was recorded by a self-reporting questionnaire. RESULTS The results revealed that the score of the GHQ12 was inversely associated with a higher frequency of low-intensity exercise (r=-0.38,p=0.001). CONCLUSIONS Our study suggests that low-intensity exercise may be a proper mean for improving the physical and mental health status of college students. School departments should take measures to push students to take part in physical activity.

ABSTRACT

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.

ABSTRACT

Objective@#This study aimed to clarify the relationship between several viral infections and clinical features of febrile seizures. The clinical expression pattern was determined according to the virus. @*Methods@#Data were collected on patients who visited the emergency room with febrile seizures from March 2016 to February 2019. The clinical characteristics of seizures and the clinical differences between each respiratory viral infection were analyzed. The severity of febrile seizures was measured by checking complex febrile seizures and electroencephalogram abnormalities. @*Results@#Of the 227 febrile convulsions, 138 (60.8%) were men, and 89 (39.2%) were women. Sixty-five patients (28.6%) had a family history of febrile seizure, 68 (30.0%) had complex seizures, and 13 (7.1%) had electroencephalogram (EEG) abnormalities. Of the 13 respiratory viruses examined, rhinoviruses were detected more significantly in 63 patients (32.4%), but there was no significant difference when comparing the rate of febrile seizure among patients with fever. There were no significant differences in the clinical features, such as body temperature, duration, and complex seizure. In addition, each virus showed a similar incidence of EEG abnormalities. @*Conclusion@#No significant difference in the clinical features and objective examination according to the virus were observed, and the tendency of developing febrile seizures is similar.

ABSTRACT

Background@#and PurposeThe first-line medications for the symptomatic treatment of rapid eye movement sleep behavior disorder (RBD) are clonazepam and melatonin taken at bedtime. We aimed to identify the association between depression and treatment response in patients with idiopathic RBD (iRBD). @*Methods@#We reviewed the medical records of 123 consecutive patients (76 males; age, 66.0±7.7 years; and symptom duration, 4.1±4.0 years) with iRBD who were treated with clonazepam and/or melatonin. Clonazepam and melatonin were initially administered at 0.25–0.50 and 2 mg/day, respectively, at bedtime, and the doses were subsequently titrated according to the response of individual patients. Treatment response was defined according to the presence or absence of any improvement in dream-enacting behaviors or unpleasant dreams after treatment. @*Results@#Forty (32.5%) patients were treated with clonazepam, 56 (45.5%) with melatonin, and 27 (22.0%) with combination therapy. The doses of clonazepam and melatonin at followup were 0.5±0.3 and 2.3±0.7 mg, respectively. Ninety-six (78.0%) patients reported improvement in their RBD symptoms during a mean follow-up period of 17.7 months. After adjusting for potential confounders, depression was significantly associated with a negative treatment response (odds ratio=3.76, 95% confidence interval=1.15–12.32, p=0.029). @*Conclusions@#We found that comorbid depression is significantly associated with a negative response to clonazepam and/or melatonin in patients with iRBD. Further research with larger numbers of patients is needed to verify our observations and to determine the clinical implications of comorbid depression in the pathophysiology of iRBD.

ABSTRACT

In diabetic ketoacidosis, hyperglycemia and ketosis result in cerebral vasculitis, which can cause cerebral edema and thrombosis. A previously healthy, 12-year-old girl visited the emergency department with a history of vomiting, polydipsia, polyuria, decreased mentality, and a 7 kg (12%) weight loss within 1 week. She showed laboratory features of severe diabetic ketoacidosis, stuporous mentality, respiratory failure, and unilateral fixed mydriasis with contralateral hemiparesis. However, brain magnetic resonance imaging showed multifocal ischemic stroke mainly involving the left posterior cerebral artery territory, instead of uncal herniation. This case highlights the possible occurrence of ischemic stroke in children with early-stage diabetes mellitus.

ABSTRACT

Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal dysplastic disease associated with mutations in the gene encoding the Runt-related transcription factor 2 (RUNX2). CCD is characterized by hypoplastic clavicles and patent cranial sutures. Management is essential to prevent complications during growth of the patient. Herein, we report a sporadic case of an infant with hypoplastic skull and clavicles at birth, which correlated with clinical findings of CCD. A heterozygous mutation was identified in the RUNX2 gene, which confirmed the diagnosis of CCD.

ABSTRACT

A 6-year-old intact male Maltese dog presented with a history of blindness and ataxia. Neuro-ophthalmic examination revealed dilated pupils with absent pupillary light reflexes and menace response in both eyes. Mild peripapillary edema was noted in the fundus of the right eye. After magnetic resonance imaging, the dog was provisionally diagnosed with meningoencephalitis of unknown etiology. Follow-up funduscopy was performed to monitor the condition of the optic discs for three years. Despite of the treatment with prednisolone, the optic nerve progressed to atrophy and the dog couldn't restore vision.

ABSTRACT

BACKGROUND AND PURPOSE: Benign epilepsy with centrotemporal spikes (BECTS) is one of the most common pediatric epilepsies, and it generally has a good prognosis. However, recent research has indicated that the epileptic activity of BECTS can cause cognitive defects such as language, visuospatial, and auditory verbal memory deficits. This study assessed language-delivery deficits in BECTS patients using diffusion-tensor magnetic resonance imaging (DTI). METHODS: T1-weighted MRI, DTI, and language tests were conducted in 16 BECTS patients and 16 age-matched controls. DTI data were analyzed using the TRActs Constrained by Underlying Anatomy tool in FreeSurfer 5.3, and 18 major white-matter tracts were extracted, which included 4 language-related tracts: the inferior longitudinal fasciculus, superior longitudinal fasciculus-parietal terminations, superior longitudinal fasciculus-temporal terminations, and uncinate fasciculus (UNC). Language tests included the Korean version of the Receptive and Expressive Vocabulary Test, Test of Problem-Solving Abilities (TOPS), and the mean length of utterance in words. RESULTS: The BECTS group exhibited decreased mean fractional anisotropy and increased mean radial diffusivity, with significant differences in both the superior longitudinal fasciculus and the left UNC (p<0.05), which are the language-related white-matter tracts in the dual-loop model. The TOPS language test scores were significantly lower in the BECTS group than in the control group (p<0.05). CONCLUSIONS: It appears that BECTS patients can exhibit language deficits. Seizure activities of BECTS could alter DTI scalar values in the language-related white-matter tracts.

ABSTRACT

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.
