Atopic dermatitis (AD) is a chronically relapsing inflammatory disorder of the skin. It is characterized by severe pruritus, sleep disturbance, and poor quality of life. In addition, AD frequently occurs in childhood and is considered the first manifestation of atopic march, which progresses into respiratory allergic diseases, such as asthma and allergic rhinitis, as the patient grow older. In this regard, the early diagnosis and active treatment of AD are required to lower the severity of disease and to prevent the development of atopic march. The proper management of AD includes avoidance of aggravating factors, barrier repair by skin care, and control of inflammation and infection with appropriate medications. Among them, identification and elimination of environmental risk factors responsible for worsening skin symptoms are essential. They include temperature, humidity, food and inhalant allergens, microorganisms, air pollutants, ultraviolet radiation, water hardness, and so forth. In particular, there is growing concern about indoor environment because time spent indoors and exposure to various kinds of pollutants is increasing with modernization and industrialization. In this review, we summarize the hazardous effect of temperature, humidity, cigarette smoke, volatile organic compounds, formaldehyde, and phthalates on the development or aggravation of AD. Current epidemiological studies and animal experiments suggest possible contributions of various indoor environmental factors to the development and aggravation of AD. However, further studies are needed to demonstrate a causal relationship between indoor environmental factors and AD.

Objective:
Research on neural correlates in the prefrontal cortex (PFC) associated with self-injurious behavior has mainly been performed in adults. However, studies on adolescents are scarce. We aimed to investigate the activation and connectivity of the PFC between adolescents with self-injurious behavior (ASI) and psychiatric controls (PC) using functional near-infrared spectroscopy (fNIRS).
Methods:
We used an emotion recognition task during fNIRS to assess 37 adolescents (23 with self-injurious behavior and 14 PC) between June 2020 and October 2021 and compared connectivity and activation between the two groups. We also measured adverse childhood events (ACE, Adverse Childhood Experiences) and performed a correlation analysis of channel activation according to ACE total scores.
Results:
The difference in activation between the groups was not statistically significant. The connectivity of channel 6 was statistically significant. The interaction between channel 6 and the ACE total score showed statistical significance between the two groups(t[33] -2.61; p=0.014). The ASI group showed a negative correlation with the total ACE score.
Conclusion
This is the first study to investigate PFC connectivity using fNIRS in ASI. It has the implication of a novel attempt with a practically useful tool to uncover neurobiological differences among Korean adolescents.

A substantial proportion of adrenal incidentalomas demonstrates subtle hormonal hypersecretion; however, adenomas that cosecrete aldosterone and cortisol are rare. We here report a case of an adrenal mass that was incidentally detected on a computed tomography scan in a 57-year-old man. The patient had a 10-year history of diabetes mellitus and a 5-year history of hypertension. Evaluation revealed hyperaldosteronemia with an elevated plasma aldosterone-to-renin ratio, hypokalemia, unsuppressed cortisol after dexamethasone administration, and elevated urinary free cortisol concentration. The appearance of the right adrenalectomy specimen indicated adrenal adenoma. Postoperatively, the blood glucose and blood pressure control improved and the urinary cortisol and aldosterone-to-renin ratio normalized. A complete endocrine evaluation in patients with incidentally discovered adrenal masses should be performed, even if the patient has a long-standing history of hypertension and diabetes, to avoid any postoperative adrenal crises.

LEOPARD multiple congenital anomaly syndrome inherited in an autosomal dominant manner. LEOPARD is an acronym for Lentigines, Eletrocardiographic conduction defects, Ocular hypertelorism, Pulmonary valve stenosis, Abnormalities of the genitalia, Retardation of growth, and Deafness. Clinical diagnosis is primarily based on multiple lentigines, typical facial features, and the presence of hypertrophic cardiomyopathy and/or cafe-au-lait macules. We report a typical case of LEOPARD syndrome with PTPN11 gene mutation associated with lentigines, electrocardiograph abnormality, ocular hypertelorism, pulmonary valve stenosis, growth retardation, and sensorineural hearing loss.

Transient global amnesia(TGA) is a transient neurological syndrome, which occurs mostly once in life. Although the pathophysiology of TGA is not yet clear, there are well-known precipitating events such as emotional stress, physical exertion, sexual intercourse, painful experiences, and immersion in cold water. We report a 67-year-old man who developed recurrent amnestic episodes fulfilling the criteria for TGA. He had vascular risk factors and precipitating events. We suggest that the number of trigger events and vascular risk factors is associated with TGA recurrence.

Gastric Hodgkin's lymphoma is extremely rare. We present a case of primary Hodgkin's lymphoma arising in the stomach of a 65-year-old woman. The patient complained of epigastric discomfort and reflux for one month. Endoscopic examination revealed a protruding lesion characterized by a smooth surface at the antrum. An abdominal computed tomography uncovered a 2.5 x 2.0 cm, exophytic submucosal mass. After the tentative preoperative diagnosis of a gastrointestinal stromal tumor, a gastric wedge resection was performed. Microscopic examination of the mass demonstrated a diffuse proliferation of large atypical lymphoid cells with mono- and binucleated pleomorphic nuclei and prominent nucleoli. Immunohistochemically, the tumor cells were positive for CD30, CD20, and CD79a, whereas they were negative for cytokeratin, carcinoembryonic antigen, CD3, CD15, epithelial membrane antigen, and anaplastic lymphoma kinase-1. Based on the morphological features and immunohistochemical results, in addition to the clinical findings, a diagnosis of primary gastric Hodgkin's lymphoma was established.

OBJECTIVES: This study was to examine the effectiveness of computerized cognitive ability enhancement program (CCAEP) using Smart-toy. The CCAEP using Smart-toy which can interact with children via bluetooth is a kids-friendly and convenient method for improving children's cognitive abilities by increasing their motivation for performing the program. We developed the CCAEP which designed to train auditory-verbal memory, visual-spatial memory, auditory-verbal working memory, and visual-spatial working memory. METHODS: Eighteen children aged 8 to 10 participated in CCAEP individual training composed of 8 sessions of 40 minutes each for 4 weeks. The effect of the training was measured with Smart Toyweb's cognitive assessment tasks (smart device based assessment) as well as traditional neuropsychological tests before and after the training. RESULTS: Children showed significant improvement in auditory-verbal memory, visual-spatial memory, auditory-verbal working memory and visual-spatial working memory abilities after the training. CONCLUSION: This study demonstrated promising results suggesting the effectiveness of CCAEP using Smart-Toy in clinical settings as well as school and home situations. Further controlled study with larger sample size including various clinical groups is needed to confirm the present results.

OBJECTIVES: To investigate the effect of a worksite-based dietary intervention program for the management of metabolic syndrome (MS) among male employees. METHODS: A dietary intervention program combining individual and environmental approach was implemented targeting white-collar employees at a worksite located in Seoul for 10 weeks. Out of 104 employees having agreed to participate in the program, those having three or more out of five components of MS and having two components, including a waist circumference component were classified into "the high risk group" (n=41) and received group nutrition education and individual nutrition counseling three times each. The rest of the study subjects were considered as "the low risk group" (n=63). The food environment at the worksite, where both the high and low risk groups were exposed, was changed to promote healthy eating. Physical data including MS components were collected and a questionnaire on dietary behaviors was administered before and after the intervention. The data from the high risk group (n=17) and the low risk group (n=20), excluding the subjects ineligible for or failed to complete the study (n=67), were analyzed. The difference before and after intervention was tested for significance by Wilcoxon signed-rank tests. RESULTS: Weight, body mass index (BMI), waist circumference, blood pressure, HDL-cholesterol, and HbA1c and the healthy dietary practice score improved significantly after intervention in the high risk group. The median number of MS components decreased significantly from 3.0 to 1.0 in the high risk group. In the low risk group, only HbA1c significantly decreased. Conclusions: The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees. CONCLUSIONS: The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees.

Women with menopause or rats with ovariectomy is associated with increased body weight, body fat and insulin resistance, which are components of metabolic syndrome. Increased prevalence of metabolic syndrome after menopause might be associated with mitochondrial dysfunction, since mitochondrial oxidative and phosphorylation activity is strongly correlated with insulin sensitivity. Although estradiol replacement prevents the metabolic syndrome, harmful effect of estradiol hampers the casual usage to prevent the metabolic syndrome. It has been reported that genistein has a mild estrogenic activity, decreases fat mass in mice and has an antidiabetic role in diabetic rats. Although insulin resistance is closely related to mitochondrial functions, there has not been yet any study in regard to the effect of dietary genistein on mitochondrial function in the insulin resistant female subjects induced by ovariectomy or similar situation. The present study investigated whether the supplementation of genistein in the high fat diet affected the mitochondrial function of high fat fed ovariectomized rats. Female Sprague Dawley rats (8 weeks old) were assigned to the following groups: sham-operated + high fat diet (S, n = 6); sham-operated + high fat diet with 0.1% genistein (S + G, n = 7); ovariectomized + high fat diet (OVX, n = 8); ovariectomized + high fat diet with 0.1% genistein (OVX + G, n = 8). Ovariectomy significantly increased body weight compared with S group. Genistein consumption in ovariectomized (OVX + G) rats decreased body weight gain compared with OVX rats. Liver weights were increased by ovariectomy. The hepatic mitochondrial protein density expressed as mg per g liver was lower in the OVX group than in the S group. However, OVX + G group showed the increased mitochondrial protein density similar to the level of S group. When mRNA levels of genes related to mitochondria such as peroxisome proliferator-activated receptor gamma coactivator 1 (PGC-1) and cytochrome c oxidase subunit III (COX III) were measured, there were decreases in the mRNA levels of PGC-1 and COX III in S + G, OVX and OVX + G group. The activity of cytochrome c oxidase was not different between groups. We could observe the decrease in succinate dehydrogenase (SDH) activity per g liver in OVX rats. Genistein supplement increased SDH activity. In conclusion, genistein supplementation to the OVX rats enhanced mitochondrial function by increasing mitochondrial protein density and SDH activity. The improvement in mitochondrial function by genistein can contribute to the improvement in metabolic syndrome.
