A small percentage of individuals have the neurological anomaly of central precocious puberty (CPP). Common neurologic causes of CPP include a tumor or congenital lesions. Although Arnold-Chiari malformation can be caused by congenital or acquired causes, it is unusual in patients with CPP. We present the case of a girl aged 4.5 years who complained of breast budding. Her neurological examination and growth pattern were normal. She had no endocrinological abnormality, except for true precocious puberty. We performed brain magnetic resonance imaging, which showed an Arnold-Chiari type 1 malformation. Currently, this case represents the youngest girl who exhibited both Arnold-Chiari type 1 malformation and precocious puberty. Furthermore, it is likely that there is a meaningful association between the brain lesion and precocious puberty in this case.

We examined the relationship between vitamin D status and health-related quality of life, and explored other related factors in the general Korean population.
We used data from the 2007–2012 Korea National Health and Nutrition Examination Survey on 14,104 adults, aged 20–49 years, who had consented to serum vitamin D measurement and answered health-related quality of life questions. EuroQol-5 was used for measurement. Serum vitamin D levels were measured at intervals of 0–9.99, 10–19.99, 20–29.99, and ≥30 ng/mL.
Participants with higher serum vitamin D (serum 25-hydroxyvitamin D) levels were significantly less likely to report problems with depression and anxiety. After adjustment for age, gender, income level, education level, marital status, alcohol consumption, smoking status, and the existence of depressive disorders, the odds ratio for reporting a problem with depression and anxiety was 0.60 (95% confidence interval [CI], 0.39–0.91). The odds ratio for the prevalence of any problem was 0.69 (95% CI, 0.53–0.89) before adjustment, but was not statistically significant after adjustment. No significant associations were observed for problems with mobility, self-care, usual activity, or pain and discomfort.
This is the first study to examine the associations between vitamin D and health-related quality of life for the general Korean population. Vitamin D status was not significantly associated with the dimensions of EuroQol-5 except for depression and anxiety problems.

Adrenocortical carcinoma (ACC) in pediatric and adolescent patients is rare, and it is associated with various clinical symptoms. We introduce the case of an 8-year-old boy with ACC who presented with peripheral precocious puberty at his first visit. He displayed penis enlargement with pubic hair and facial acne. His serum adrenal androgen levels were elevated, and abdominal computed tomography revealed a right suprarenal mass. After complete surgical resection, the histological diagnosis was ACC. Two months after surgical removal of the mass, he subsequently developed central precocious puberty. He was treated with a gonadotropin-releasing hormone agonist to delay further pubertal progression. In patients with functioning ACC and surgical removal, clinical follow-up and hormonal marker examination for the secondary effects of excessive hormone secretion may be a useful option at least every 2 or 3 months after surgery.

Frailty and cognitive impairment are considered the most common and yet least understood conditions in older adults. This study was conducted to investigate the correlation between frailty and cognitive function in non-demented older Koreans.
Korean Mini-Mental Status Examination (K-MMSE) scores and Cardiovascular Health Study Frailty Indices were obtained for 486 older adults aged 65 and over who registered at six senior welfare centers in Seoul and Gyeonggi province. Multiple linear regression was performed to identify the association between frailty and K-MMSE scores.
Of the 486 older adults, 206 (42.4%) were robust, 244 (50.2%) were prefrail, and 36 (7.4%) were frail. Prevalence of cognitive impairment (K-MMSE ≤ 23) was 6.3% in the robust group, 16.8% in the prefrail group, and 30.6% in the frail group (P < 0.001), and mean K-MMSE score was 27.5 ± 2.2, 26.5 ± 3.1, and 23.7 ± 5.3, respectively (P < 0.001). Frailty tended to be associated with lower MMSE scores (B = -1.92, standard error, 0.52; P < 0.001).
Frailty was found to be correlated with cognitive impairment in non-demented older Koreans. However, further cohort studies are required to determine the association between frailty and cognitive function.

The Family Adaptability and Cohesion Evaluation Scale (FACES) III using the circumplex model has been widely used in investigating family function. However, the criticism of the curvilinear hypothesis of the circumplex model has always been from an empirical point of view. This study examined the relationship between adolescent adaptability, cohesion, and adolescent problem behaviors, and especially testing the consistency of the curvilinear hypotheses with FACES III.
We used the data from 398 adolescent participants who were in middle school. A self-reported questionnaire was used to evaluate the FACES III and Youth Self Report.
According to the level of family adaptability, significant differences were evident in internalizing problems (P = 0.014). But, in externalizing problems, the results were not significant (P = 0.305). Also, according to the level of family cohesion, significant differences were in internalizing problems (P = 0.002) and externalizing problems (P = 0.004).
The relationship between the dimensions of adaptability, cohesion and adolescent problem behaviors was not curvilinear. In other words, adolescents with high adaptability and high cohesion showed low problem behaviors.
