PURPOSE: To identify the brain centers associated with visually evoked sexual arousal in the human brain, and to investigate the neural mechanism for sexual arousal using functional MRI (fMRI). MATERIALS AND METHODS: A total of 20 sexually potent volunteers consisting of 10 males (mean age: 24) and 10 females (mean age: 23) underwent fMRI on a 1.5 T MR scanner (GE Signa Horizon). The fMRI data were obtained from 7 slices (10 mm slice thickness) parallel to the AC-PC (anterior commissure and posterior commissure) line, giving a total of 511 MR images. The sexual stimulation consisted of a 1-minute rest with black screen, followed by a 4-minute stimulation by an erotic video film, and concluded with a 2-minute rest. The brain activation maps and their quantification were analyzed by the statistical parametric mapping (SPM 99) program. RESULTS: The brain activation regions associated with visual sexual arousal in the limbic system are the posterior cingulate gyrus, parahippocampal gyrus, hypothalamus, medial cingulate gyrus, thalamus, amygdala, anterior cingulate gyrus, insula, hippocampus, caudate nucleus, globus pallidus and putamen. Especially, the parahippocampal gyrus, cingulate gyrus, thalamus and hypothalamus were highly activated in comparison with other areas. The overall activities of the limbic lobe, diencephalon, and basal ganglia were 11.8%, 10.5%, and 3.4%, respectively. In the correlation test between brain activity and sexual arousal, the hypothalamus and thalamus showed positive correlation, but the other brain areas showed no correlation. CONCLUSION: The fMRI is useful to quantitatively evaluate the cerebral activation associated with visually evoked, sexual arousal in the human brain. This result may be helpful by providing clinically valuable information on sexual disorder in humans as well as by increasing the understanding of the neuroanatomical correlates of sexual arousal.

PURPOSE: Who may dare to state that optimal choice of treating nasal bone fracture is closed reduction? Few decades of authors' experience in nasal bone fracture has lead to believe that more active and assertive approach in nasal bone fracture by performing simultaneous lateral osteotomy may be applied in proper indications to acquire more accurate reduction and cosmetically satisfying result. METHODS: From May 2008 to October 2009, among 241 nasal bone fracture patients, 20 patients underwent simultaneous lateral osteotomy with nasal bone fracture reduction. Followed by rigid septal correction, nasal cavity is packed to stabilize the fracture segment for safer osteotomy. Through intranasal incision, in selected cases of difficult reduction or for cosmetic purposes, various types of lateral osteotomy was performed corresponding to the fracture anatomy, conditions of the nasal cavity. Postoperative nasal packing was retained for one week and nasal dorsum splint for 3 weeks. RESULTS: Lateral osteotomy was utilized for difficult cases of closed reduction, for correction of wide nose, hump and deviation in 9, 5, 2, and 4 cases, respectively. Patient satisfaction was scaled 90% in satisfaction and moderate in 10% (2 cases), complaining of mild nasal tip deviation. Physicians detected 2 cases of apparent deformity with patient recognition; one patient with mild step deformity at the osteotomy site and the other patient with minimal implant mobility. CONCLUSION: By accompanying profound understanding of the fracture anatomy, more active and assertive approach in nasal fracture reduction can be coincide with simultaneous lateral osteotomy to reduce the rate of secondary deformity and to obtain more cosmetically satisfying result.

This study analyzed the services as operated by the Child Health Telephone Service Center. The Center is a toll free service operated as part of the community services of the Korean Academic Society of Child Health Nursing. The aim of the study was to describe the concerns of child caregivers regarding child health care as discussed during telephone counseling. Specific objectives were as follows: 1. To analyze the activities of the Center. 2. To describe the characteristics of caregivers who made phone calls for counseling services and also the characteristics of their children. 3. To analyze the content of the counseling sessions. 4. To analyze counseling content according to the characteristics of the caregivers and their children. Data used for the study were obtained from the counseling records for the period from Sept. to Dec. 1999, as kept by the three counselors at the Center. The total number of calls was 8,261 and that consisted of 15,150 questions. The total questions were merged into 13,236 by eliminating those questions which overlapped or were of similar content. The final 13,236 questions were used for the final analyses. Almost of the callers (98.4%) were mothers. Among them 89.6% were between 25 and 35 years of age. Geographical distribution of the callers covered the whole nation. The largest numbers who made the calls were from the Seoul metropolitan area (36%), followed by 28% from Kyung Gi Province, and 20% were from the Kyung Sang area. Among 8,261 callers, 72.8% were first users. Sex of the babies and children in question for counseling was about even for males and females and ages ranged from one month to six years. The largest group (62.5%) was the less than six month age group. The finalized 13,236 questions/problems were categorized into 11 problem areas. They were in order of frequency, physical problems, feedings and nutrient concerns, information on child rearing, growth and development, guidance on utilization of child care facilities, elimination problems, sleeping concerns, immunization related concerns, behavior problems, injury and accidents, and safety measures. The most frequent problems for counseling were physical signs and symptoms (27.3%), followed by feeding and nutrients, information on child rearing, and growth and development. Of physical problems, abnormal gastrointestinal signs and symptoms were the most frequent concern and skin problems were next at 25% and 23.3% respectively. Loose bowels, vomiting and constipation were the most frequent gastrointestinal problems. Atopic dermatitis had the highest frequency at 53.3% with diaper rash being the second highest among the skin problems. About 80% of the growth and developmental category were physical development concerns related to physiological, body growth, and motor and sensory development. This study constitutes the activity report for the first year of the Center. The findings correspond with literature reports on child health problems and parents educational needs. One recommendation from this study is that since the services of the Center are carried out only by telephone, the psychology of the counselees and the counselor relationship must be considered for better services.

BACKGROUND: It is uncommon to unexpectedly discover pituitary tumor as a hypermetabolic lesion on an 18F-FDG PET-CT scan for the evaluation of an unrelated disease when the patient does not show neurological or endocrine signs and symptoms. METHODS: We retrospectively analyzed the medical records of 16 patients with pituitary tumor that was detected incidentally on 18FFDG PET-CT at the Korea Cancer Center Hospital from January 2002 to September 2009. We analyzed their clinical features in detail. RESULTS: On 35,505 18F-FDG PET-CT scans, 16 (0.045%) patients were diagnosed with pituitary incidentaloma. They underwent 18FFDG PET-CT for the evaluation of the state of malignancy. All of them had no signs and symptoms related to pituitary tumor. The average age of the patients was 63.3 +/- 12.0 years (49-85 years). Eleven patients were men and 5 were women. The mean diameter of the tumor was 17.9 +/- 5.7 mm. Most of the pituitary incidentalomas were macroadenoma. The result of tumor morphologic evaluation by the Hardy classification was as follows: 6 grade IV, 1 grade III, 3 grade II and 1 grade I. The mean standardized uptake value of the tumor was 10.6 +/- 6.7. Ten patients had endocrine evaluation and they showed a normal hormone level. Among 16 patients, 4 patients received TSA and they were diagnosed with pituitary adenoma. CONCLUSION: This study showed that pituitary incidentaloma discovered on 18F-FDG PET-CT was extremely rare. It was almost all non-functioning macroadenoma and this showed relatively high FDG uptake.

Background:
Active surveillance (AS) has emerged as a viable management strategy for low-risk papillary thyroid microcarcinoma (PTMC), following pioneering trials at Kuma Hospital and the Cancer Institute Hospital in Japan. Numerous prospective cohort studies have since validated AS as a management option for low-risk PTMC, leading to its inclusion in thyroid cancer guidelines across various countries. From 2016 to 2020, the Multicenter Prospective Cohort Study of Active Surveillance on Papillary Thyroid Microcarcinoma (MAeSTro) enrolled 1,177 patients, providing comprehensive data on PTMC progression, sonographic predictors of progression, quality of life, surgical outcomes, and cost-effectiveness when comparing AS to immediate surgery. The second phase of MAeSTro (MAeSTro-EXP) expands AS to low-risk papillary thyroid carcinoma (PTC) tumors larger than 1 cm, driven by the hypothesis that overall risk assessment outweighs absolute tumor size in surgical decision-making.
Methods:
This protocol aims to address whether limiting AS to tumors smaller than 1 cm may result in unnecessary surgeries for low-risk PTCs detected during their rapid initial growth phase. By expanding the AS criteria to include tumors up to 1.5 cm, while simultaneously refining and standardizing the criteria for risk assessment and disease progression, we aim to minimize overtreatment and maintain rigorous monitoring to improve patient outcomes.
Conclusion
This study will contribute to optimizing AS guidelines and enhance our understanding of the natural course and appropriate management of low-risk PTCs. Additionally, MAeSTro-EXP involves a multinational collaboration between South Korea and Australia. This cross-country study aims to identify cultural and racial differences in the management of low-risk PTC, thereby enriching the global understanding of AS practices and their applicability across diverse populations.
