The distributions and morphological characteristics of neurons displaying immunoreactivity to the catecholamine synthetic enzymes, tyrosine hydroxylase[TH], dopamine-beta-hydroxylase[DBH], and phenyletha-nolamine-N-methyltransferase[PNMT] were examined in the adjacent sections of the diencephalon of the striped field mouse [Apodemus agrarius coreae].Only TH-, and no DBH- or PNMT-immunoreactive neurons were found in the diencephalon. In the preoptic area, TH-immunoreactive neurons were found in the anterior preoptic nucleus of Loo[APN], periventricular preoptic nucleus, medial preoptic nucleus, lateral preoptic nucleus and suprachiasmatic nucleus. In the hypothalamus, TH-immunoreactive neurons were found in theparaventricular hypothalamic nucleus, periventricular gray, retrochiasmatic area,anterior hypothalamic nucleus of anterior hypothalamic area and retrochiasmatic region of the hypothalamus. In the rostral tuberal region of the hypothalamus, TH-immunoreactive neurons were found in the paraventricular nucleus, periventricular gray and arcuate nucleus. In the midtuberal region of the hypothalamus, TH-immunoreactive neurons were found in the paraventricular nucleus, dorsomedial hypothalamic nucleus, zona incerta and arcuate nucleus. In the caudal tuberal region of the hypothalamus, dorsal hypothalamic nucleus, posterior hypothalamic complex and arcuate nucleus.

Purpose:
To compare the efficacy and safety of radiofrequency ablation (RFA) and ethanol ablation (EA) followed by RFA in treating mixed cystic and solid thyroid nodules.
Materials and Methods:
We included 243 nodules from 243 patients who underwent RFA for mixed cystic and solid benign nodules. The nodules were divided into two groups (RFA alone and EA + RFA). We evaluated volume reduction rate (VRR), therapeutic success rate, improvement in symptomatic and cosmetic issues, complications, and adverse effects.
Results:
The RFA group included 204 patients, and the EA + RFA group included 39 patients.The long-term success rates in the RFA only and EA + RFA groups were 90.2% and 97.4%, respectively. The mean VRR at the last follow-up in the RFA and EA + RFA groups were 81.6% and 87.2%, respectively. Therapeutic results were similar in both groups at the last followup. Cosmetic and symptomatic problems markedly improved in both groups. No major complications were observed.
Conclusion
Both RFA alone and EA + RA are safe and effective methods for treating mixed cystic and solid thyroid nodules, although EA + RFA is slightly more effective.

BACKGROUND: This study was conducted to examine if basal luteinizing hormone (LH) levels could be useful for screening central precocious puberty (CPP) in girls. METHODS: A total of 90 girls under the age of 8 years were included in this study. They underwent the gonadotropin-releasing hormone (GnRH) stimulation test at Good Gang-An Hospital from March 2008 to December 2012 for evaluation of premature sexual development. Patients were classified into two groups: the pubertal response group of patients who had 5 IU/L peak LH levels in the GnRH stimulation test, and the prepubertal response group of patients who had LH levels <5 IU/L. Chronological and bone ages, height, weight, body mass index, gonadotropin response to GnRH stimulation, and basal levels of LH, follicle-stimulating hormone, and estradiol were studied in both groups. The relationship between basal LH and peak-stimulated LH was evaluated using Spearman's correlation. To determine the optimal cut-off values of basal LH levels for differentiating between two groups, the receiver operating characteristic (ROC) curves were analyzed. RESULTS: When the correlation between basal LH levels and peak LH after GnRH stimulation was analyzed in all subjects (N=90), basal LH levels had a statistically significant positive correlation with peak stimulated LH levels (rs=0.493, p<0.001). The cut-off level of optimal basal LH was 0.1 IU/L, according to the ROC curves. Its sensitivity was 73.3%, and its specificity was 77.8%. CONCLUSION: The study results showed that serum basal LH levels are useful for screening CPP in girls.

PURPOSE: The purpose of this study was to evaluate the clinical characteristics of children who had been diagnosed as specific language impairment as outpatients. METHODS: One hundred twenty-five speech- or language-delayed patients were enrolled in Dae-Dong Hospital from July 2007 to June 2008. Fifty-one of 125 children were diagnosed as specific language impairment in whom clinical factors such as duration of therapy and progress after therapy were evaluated. Data were obtained from telephone or direct personal interviews. RESULTS: Among 51 children diagnosed as specific language impairment, 39 (76.5%) had mixed receptive-expressive-type language disorder and 12 (23.5%) had expressive-type language disorder. Thirty children in total were studied as ten children were unavailable for follow-up and eleven dropped out during treatment. The final 30 children consisting of 23 with mixed receptive-expressive type language disorder and seven children with expressive-type language disorder were treated after diagnosis. Total average treatment duration of children with mixed receptive-expressive-type and expressive-type language disorder were 18.1 months and 8.6 months, respectively, a statistically significant difference (P = 0.014). Thirteen (57%) of 23 children with mixed receptive-expressive-type language disorder and all (100%) seven children with expressive-type language disorder completed speech therapy with an average treatment duration of 12.2 and 8.6 months, respectively; however, this difference was not statistically significant(P = 0.287). CONCLUSION: Classifying patients with specific language impairments into mixed receptive-expressive-type and expressive-type language disorder in an outpatient department can be useful for predicting duration of and prognostic effects of language therapy, as our study and other previous articles have shown. More attention is needed from pediatricians to ensure the effective assessment and management of specific language impairment.

Colonic phytobezoars are defined as conglomerate masses of fruit or vegetable matter in the colon, and these have rarely reported as a cause of colon obstruction. Because it is extremely rare, its correct diagnosis might be delayed even with the aid of abdominal computed tomography. We report here on a case of diagnosed colonic obstruction due to colonic phytobezoars in a 67-year-old female with diabetic end stage renal disease and chronic constipation. Although abdomino-pelvic computed tomography did not demonstrate the presence of phytobezoars, multiple phytobezoars impacted in the colon were found and these were removed by colonoscopy. This is a rare case in that colonic obstruction due to phytobezoar was diagnosed early and it was treated by colonoscopy.

Behcet disease is a multisystemic disorder characterized by a chronic relapsing triple symptom complex of recurrent oral ulceration, genital ulceration, and ocular inflammation. The onset of Behcet disease is rare in old age as is whole colon involvement. We recently saw a 78-year-old female patient examined to have intestinal Behcet disease with diffuse colon ulcers. She was admitted due to multiple oral ulcers, genital ulcers, low abdominal pain, and hematochezia. Colonoscopy showed multiple well-demarcated, large, deep, bleeding ulcers from the cecum into the descending colon. The patient was diagnosed with Behcet disease and treated with steroid, colchicine, and mesalazine. This paper describes a case of Behcet disease with unusual intestinal distribution.

BACKGROUND: Insulin resistance is related to central obesity and the amount of skeletal muscle. A simple and practical anthropometric marker for muscle mass is not known, although waist circumference (WC) is used as an indicator of abdominal obesity. The aims of this study were to investigate whether arm (AC) and thigh circumferences (TC) can be used as an indicator of muscle mass and if they are related to muscle strength. METHODS: A total of 110 obese (body mass index [BMI]> or =25 kg/m2) women with type 2 diabetes were enrolled, and WC, AC, and TC were measured. Abdominal visceral fat (AVF), subcutaneous fat (ASF), and total fat (ATF) were assessed by computed tomography, regional muscle (MM), and fat mass by dual-energy X-ray absorptiometry, muscle strength by one repetition maximum (1RM) of both extremities (chest and leg press) and insulin resistance by KITT. RESULTS: The mean age was 56.2+/-7.3 years, duration of diabetes was 4.2+/-4.4 years, and BMI was 27.2+/-2.8 kg/m2. WC was correlated with ATF, AVF, and ASF (r=0.728, P<0.001; r=0.515, P<0.001; r=0.608, P<0.001, respectively). Arm MM was correlated with AC (r=0.500, P<0.001), and leg MM with TC (r=0.291, P=0.002). Upper 1RM was related to AC/WC ratio (r=0.359, P<0.001), and lower 1RM was to TC/WC ratio (r=0.286, P=0.003). Insulin resistance had significant relations with AVF, WC, and total MM (r=-0.262, P=0.008; r=-0.217, P=0.029; r=0.160, P=0.031, respectively). CONCLUSION: The muscle mass was related to extremity circumferences, and muscle strength was to extremity/waist circumference ratio in obese women with type 2 diabetes.
