Background : Bell's palsy(BP) is defined as an idiopathic peripheral facial paralysis of sudden onset and account more than 50% of facial paralysis. It's etiology is unclear, but herpes simplex virus type-1(HSV-1) has been the most suspicious causative agent of BP that ever been studied. We evaluated the effect of add-on acyclovir in acute stage of BP. Methods : Subject consisted of 35 patients who developed acute idiopathic unilateral facial nerve palsy(16 men and 19 women with age 9-78 years old). The treatments were started within 10 days after onset of BP. Facial nerve function was assessed by the House-Brackman facial nerve grading scale and facial nerve conduction study including blink reflex. Follow-up evaluation were made 2 month after onset. Twenty of 35 patients were treated with combined therapy of acyclovir and prednisone. As a control group, 15 patients were treated with prednisone only. We compared the improvement of neurologic defects at recovery phase. Results : Compared with two groups, difference in grading scale at recovery phase is statistically significant(p<0.01). So, acyclovir-prednisone group showed a significant improvement in grading scale at recovery phase compared with prednisone group. Conclusion : We identified the benefits of add-on acyclovir in the acute stage of BP.

Purpose: A relationship between Febrile seizure (FS) and iron deficiency anemia (IDA) has been found in several studies. However, few studies have focused on the role of IDA in complex febrile seizures (CFS) and simple febrile seizures (SFS) and there is no report on whether IDA is a risk factor for recurrence. The aim of this study was to investigate the role of IDA in SFS and CFS and to examine the effect of IDA on recurrence. Methods: Patients (n=166) who had been diagnosed with FS were enrolled in our study. Subjects were divided into the following groups for analysis: the SFS and CFS groups, recurrence and non-recurrence groups. The onset age was compared in each group of patients and laboratory test results based on IDA were compared. Results: Between the SFS and the CFS groups, there was no significant difference in laboratory test results based on IDA. There was a significant difference in onset age between the two groups and the onset age tended to be lower in the CFS group (24.00 vs. 16.49 months) (P=0.004). Comparing recurrence and non-recurrence groups, the mean corpuscular volume was significantly different (P=0.043) with the recurrence group having a lower mean corpuscular volume level (78.92 vs. 77.48). The onset age in the recurrence group was lower (26.02 vs. 19.68 months). Conclusion: This study suggests that onset age could be a risk factor for CFS, and IDA may not contribute to elevating the risk of CFS. However, IDA may play an important role in the recurrence of FS.

Objective: This study aimed to evaluate the mean age of menarche, its secular trend in Korean women, and the relationship between malocclusion and the rate of skeletal maturation, as defined by menarcheal age. Methods: We retrospectively collected data on menarcheal age from 931 Korean women born during 1961 - 1997. Subjects were divided by the malocclusion type and birth-year decade into 3 and 4 groups, respectively. The mean menarcheal age for each group was determined, and one-way ANOVA was performed for intergroup comparison (p = 0.05). Two-way ANOVA was also performed to compare all the 12 subgroups (p = 0.05). Results: The mean age of menarche was 12.82 years for Korean women born during 1961 - 1997. A distinct downward secular trend of menarcheal age was noticed (p < 0.05). For the birth-year decade 1961 - 1970, the Class III malocclusion group showed earlier onset of menarche than the other malocclusion groups (p < 0.05), but the other birth-year groups did not show any significant difference in the type of malocclusion (p > 0.05). Conclusions: A positive secular trend towards earlier menarche exists among Korean women. Malocclusion does not show any significant relationship with the rate of skeletal maturation, as defined by menarcheal age.

Purpose : Hyperbilirubinemia, jaundice and gallbladder hydrops are unusual manifestations of Kawasaki disease (KD). In this case, abdominal pain, anorexia and abdominal distension may follow eventfully. We reviewed the clinical and laboratory data to investigate the causative factors of hyperbilirubinemia in patients with KD. Methods : Two-hundred eighty two children diagnosed and hospitalized with KD were identified by searching patients' charts. Cases were included in the study if diagnosed between January 1997 and December 2004. We reviewed clinical data, age, sex, duration from the onset of fever to admission and duration from start of treatment to defervescence. Clinical and laboratory data were compared between normal (A) and hyperbilirubinemia (B) groups. Results : Thirteen patients (4.6 percent) showed hyperbilirubinemia. In the hyperbilirubinemia group, age and initial ALT value were higher than group A (P=0.003, 0.018 respectively). Duration from the onset of fever to admission and age were relative risk factors in hyperbilirubinemia (P=0.007, 0.003 respectively) in patients with KD. Conclusion : Shorter duration from the onset of fever to admission and older age group were relative risk factors of hyperbilirubinemia in patients with KD.

Aberrations in VOT measures in apraxia of speech are indicative of speech motor programming impairment. In English, overlaps of VOT between voiceless and voiced plosives have been frequently observed in patients with apraxia of speech. Unlike English, Korean plosives constitute trichotomy in terms of manner of production, that is, voiceless aspirated /p', t', k'/ ; voiceless or voiced, weakly aspirated /p-b, t-k, k-g/ ; or voiceless, heavily aspirated /p, t, k/. In this spectrographic study, VOT measures during Korean plosives produced by a patient with apraxia of speech were compared to those by age- and gender- matching normal subjects. The results indicated that there were partial overlaps between VOT of /b, d, g/ and those of /p, t, k/, implying that the errors were phonetic in nature. In addition, larger VOT variabilities in apraxia of speech compared to the normals were noted.

Inflammatory bowel disease (IBD) is a chronic relapsing disorder of unknown etiology, which is believed to be multifactorial. Recently, the incidence of pediatric IBD has steeply increased in Korea since 2000. Poorly controlled disease activity can result in complications such as intestinal fistulae, abscess, and stricture, as well as growth retardation and delayed puberty in children. Because of a lack of confirmative tests, various diagnostic modalities must be used to diagnose IBD. Onset age, location, behavior, and activity are important in selecting treatments. Monogenic IBD must be excluded among infantile and refractory very-early-onset IBD. Early aggressive therapy using biologics has recently been proposed for peripubertal children to prevent growth failure and malnutrition.

We investigated the effects of vitamin E supplementation on the protein glycosylation in vivo. Weaned KK-mice were fed high fat diet containing 20% corn oil(wt/wt), and sacrificed at 4, 6, and 0 months of age. High vitamin E diet was the high fat diet supplemented with an excess amount of 이-$\alpha$-tocopheryl acetate(2080IU/kg diet). We measured $HbA_{1C}$ as a glycosylation early product, and collagen-linked fluorescence (CLF) of skin as a glycosylation and product. We found that diabetic group had increased levels of $HbA_{1C}$ within 2 months after onset of diabetes and during the experiments. The skin CLF increased dramatically 5 months after onset of diabetics. Treatment with vitamin E did not modify the level of blood glucose. However, we observed a significant lowering in CLF and $HbA_{1C}$ in diabetic mice.

Fifty six dogs diagnosed with intervertebral disk disease between January 1999 and August 2001 were reviewed to characterize signalments and prognosis. Seventy-five percent was chondrodystrophoid breeds (42 dogs). Mean age was 5.1$\pm$3.0 year-old and fifty-four percent had acute onset. Interspaces between eleventh thoracic vertebrae and fourth lumbar vertebrae were affected most commonly. Success rate of conservative treatment to dogs with paresis was 83% and that of operation to dogs with paralysis was 67%. Six dogs were recurred and 50% of them had recovered again. There was significant correlation between success rate of treatment and the degree of clinical signs but there was no significant correlation between success rate of treatment and rate of onset, status of clinical signs, duration of clinical signs.

Familial Creutzfeldt-Jakob Disease (fCJD) is characteristic with older age onset, relatively low occurrence rate, slower progression and lower possibility of developing myoclonus, cerebellar, pyramidal signs and visual disturbance compared with classical sporadic CJD. We report a case of 75-year-old male patient presented with sudden onset of right side weakness with Broca's aphasia who has been diagnosed with fCJD with V180I mutation. This case indicates that fCJD with V180I mutation can have stroke-like initial presentation.

The prevalence of childhood and adolescent obesity has increased and exacerbated during the coronavirus disease 2019 pandemic, both in Korea and globally. Childhood and adolescent obesity poses significant risks for premature morbidity and mortality. The development of serious comorbidities depends not only on the duration of obesity but also on the age of onset. Obesity in children and adolescents affects almost all organ systems, including the endocrine, cardiovascular, gastrointestinal, reproductive, nervous, and immune systems. Obesity in children and adolescents affects growth, cognitive function, and psychosocial interactions during development, in addition to aggravating known adult comorbidities such as type 2 diabetes mellitus, hypertension, dyslipidemia, nonalcoholic fatty liver disease, obstructive sleep apnea, and cancer. Childhood and adolescent obesity are highly associated with increased cardiometabolic risk factors and prevalence of metabolic syndrome. The risk of cardiovascular and metabolic diseases in later life can be considerably decreased by even a small weight loss before the onset of puberty. Childhood and adolescent obesity is a disease that requires treatment and is associated with many comorbidities and disease burdens. Therefore, early detection and therapeutic intervention are crucial.
