Purpose: McCune-Albright syndrome (MAS) is caused by activating mutations in the GNAS gene, resulting in peripheral precocious puberty, caf$\acute{e}$-au-lait spots, and polyostotic fibrous dysplasia (POFD). The aim of the present study was to describe the diverse clinical and endocrine characteristics of patients with MAS. Methods: Seven patients with MAS were included in this study and medical charts were reviewed retrospectively for following parameters: patient's sex and age at diagnosis, POFD, ovarian cysts, and precocious puberty. Results: The mean age at diagnosis was $5.8{\pm}4.2$ years. One patient was male (14%) and the other six patients were female (86%). Peripheral precocious puberty was associated with 6 patients (86%). Five patients manifested premature menarche as early as 2 to 5 years of age. Letrozole was administered to 4 patients, tamoxifen to one patient and GnRH agonist to one patient. Five females developed ovarian cysts. Thyroid function tests were performed in all patients and one patient showed hyperthyroidism (14%) and has been treated with methimazole. One patient presented with pseudohypoparathyroisdism, phosphaturia, calciuria suggesting hypophosphatemic rickets. Six patients (86%) revealed POFD. One patient had symptoms of optic nerve compression and secondary esotropia and 2 patients had bone pain. Conclusion: This study described clinical characteristics and endocrine complications of patients with MAS. Careful physical examinations with history taking and serial endocrine function tests should be needed to detect complications such as endocrinologic hyperfunction and POFD.

To evaluate the diagnostic accuracy of the measurement of free thyroxine (FT4) by radioimmunoassay, we measured free $T_4\;and\;T_4,\;T_3,\;T_3RU$, TSH and TBG serum levels by radioimmunoassay in 18 healthy persons and 52 patients with various thyroid diseases and 11 normal pregnant women. The results are as follows. 1. In 19 cases of overt hyperthyroidism, $T_3,\;free\;T_4$ and FTI, $T_4/TBG$ ratio reflect hyperfunction in all cases. $T_4$ is increased in 94% (18/19) and TBG and TSH are decreased in 79% (15/19). 2. In 8 patients with overt hypothyroidism, TSH is increased in all cases and free $T_4$ and FTI is decreased in all cases. $T_4$ is decreased in 87.5% (7/8), $T_3$ is decreased in 75% (6/8) and $T_4/TBG$ ratio is decreased in 62.5% (5/8). 3. In 5 patients who are clinically in euthyroid state after treatment of hyperthyroidism, $T_4,\;free\;T_4$, FTI and TSH are in the normal range in all cases and $T_3$ is normal in 60% (3/5) and slightly increased in 40% (2/5). 4. In 10 patients who showed clinically borderline hypothyroidism after treatment of hyperthyroidism, TSH is increased in all cases and free $T_4$ and FTI are decreased in all cases, but $T_4\;and\;T_3,\;T_4/TBG$ ratio are in the normal limit in all cases. So after treatment of hyperthyroidism, TSH, free $T_4$ or FTI are recommended as optimal thyroid function test. 5. In normal pregnancy, free $T_4$, FTI and $T_4/TBG$ ratio reflect normal function, but the other parameters revealed unreliable due to the influence of increased TBG. Also TBG and TSH level in pregnancy is increased significantly compared with normal healthy control group. 6. The coefficients of correlation between free $T_4$ and FTI were 0.862 (p<0.001) and 0.685 (p<0.001) between free $T_4\;and\;T_4/TBG$ ratio. In most patients, diagnostic value of free $T_4$ was comparable and even superior to FTI, so free $T_4$ measurement can be used routinely with thyrotropin assay in the diagnosis of hypothyrodism or with $T_3$ for the diagnosis of hyperthyroidism.

Background and Objectives: In patients with asthma, increased obstruction and resistance of airway result in impairment in the generation of voice. Allergy and nasal polyposis, which are frequently observed in patients with asthma, are other factors that affect the vocal performance. Bronchodilators and steroids are commonly used in the treatment of asthma, and these agents also have been reported to be associated with voice changes. The aim of this study is to evaluate the voice quality in patients with mild to-moderate asthma by subjective and objective methods. Materials and Methods: A total of 36 patients with asthma established in the Department of Respiratory Medicine were included in this study. 23 were women and 13 were men, with a mean age of 51.7 years. The average duration of asthma was 77.0 months. All patients had mild-to moderate asthma. Acoustic and aerodynamic analyses were performed and the movements of the vocal cords were examined by videolaryngostroboscopy (VLS). Voice Handicap Index (VHI) and GRABS scales were used for subjective evaluations. Results: 50% of patients suffered from dysphonia and FO was 119.3${\pm}$23.7 Hz in male and 198.2${\pm}$18.4 Hz in female patients. There were no significant differences in average shimmer and NHR between females (4.90${\pm}$2.95% ; 0.1O${\pm}$0.04 dB) and males (4.64${\pm}$2.45% ; 0.20${\pm}$0.15 dB). However, the value of jitter was greater for females (2.60${\pm}$1.92%) than for males (1.21${\pm}$0.84%). The VHI score was above the normal limit in 35%, and VLS findings were shown diverse abnormality in 89% asthmatics from mucosal change to hyperfunction of supragottis and contact granuloma. But duration of illness and steroid dose did not correlate with these findings. Conclusion: Subjective and objective abnormality was shown in more than 50% of asthmatic patients. We suggest that persons who suffer from asthma should be examined for possible voice disorders by laryngologist. Additionally, appropriate medical care and voice therapy should be provided for those who have voice disorders associated with asthma.

Objective: This study aimed to explore the feasibility of functional evaluation of the lateral pterygoid muscle (LPM) using diffusion tensor imaging (DTI) in patients with temporomandibular joint disorders (TMDs). Materials and Methods: A total of 119 patients with TMD (23 male and 96 female; mean age ± standard deviation, 41 ± 15 years; 58 bilateral and 61 unilateral involvements for a total of 177 joints) and 20 healthy volunteers (9 male and 11 female; 40 ± 13 years; 40 joints) were included in this prospective study. Based on DTI of the jaw in the resting state, the diffusion parameters, apparent diffusion coefficient (ADC), fractional anisotropy (FA), λ1, λ2, and λ3 of the superior and inferior heads of the LPM (SHLPM and IHLPM) were measured. Patients with TMD with normal disc position (ND), anterior disc displacement with reduction (ADWR), and anterior disc displacement without reduction (ADWOR) were compared. Results: Patients with TMD overall, and ADWR and ADWOR subgroups had significantly higher ADC, λ1, λ2, and λ3 in both the SHLPM and IHLPM than those in volunteers (p < 0.05 for all), whereas the ND subgroup only had significantly higher ADC and λ1 (p < 0.001). Meanwhile, significant differences in FA in the SHLPM and IHLPM were found between volunteers and ADWOR (p = 0.014 and p = 0.037, respectively). Among the three TMD subgroups, except for λ3 and FA in the ADWR subgroup, ADWR and ADWOR subgroups had significantly higher ADC, λ1, λ2, and λ3 and lower FA than those in the ND group (p < 0.050). There was no significant difference in diffusion variables between ADWR and ADWOR. In ADWOR, the osteoarthritis group had significantly higher λ3 and lower FA values in the IHLPM than those in the non-osteoarthritis group. Conclusion: DTI successfully detected functional changes in the LPM in patients with TMD. The unsynchronized diffusivity changes in the LPM in different subgroups of TMD signified the possibility of using diffusion parameters as indicators to identify the severity of LPM hyperfunction at various stages of TMD.

1993년 2월부터 1994년 8월까지 경북대학교병원 핵의학과에서 진료한 갑상선질환 중 그레이브스병 402예와 하시모토갑상선염 230예를 대상으로 혈청 thyrotropin-binding inhibiting immunoglobulin (TBII)치를 방사면역측정법으로 측정하여 갑상선 기능상태와 그 치료경과에 있어서의 동태를 관찰하고 아울러 혈청 갑상선글로블린치, antithyroglobulin anti-body(ATAb) 및 antimicrosomal antibody(AMAb)의 동태를 동시에 검토하여 다음과 같은 결과를 얻었다. 혈청 TBII치는 갑상선기능항진성 그레이브스병에서 평균 $40.82{\pm}21.651%$, 하시모토갑상선염에서 평균 $8.89{\pm}14.522%$로서 정상 대조군의 평균 $3.21{\pm}2.571%$에 비하여 유의한 상승치를 보였다. 그레이브스병 중에서도 갑상선기능항진증이 있는 387예에서는 TBII치가 비정상적으로 증가한 예가 92.2%(357예)였으며, 갑상선기능이 정상으로 회복된 그레이브스병 15예에서는 TBII치가 비정상적으로 증가된 예는 46.7%(7예)에 불과하였다. 하시모토갑상선염 230예에서는 TBII치가 비정상적으로 상승한 예는 23.9%(55예)였다. 그레이브스병에서 TBII치들은 RAIU 6시간치 및 24시간치, T3, T4, FT4들과 유의한 양의 상관성을 나타내었으며, 혈청 갑상선글로블린 및 AMAb와도 양의 상관성을 나타내었다(p<0.001). 그러나 혈청 TBII치와 TSH와는 음의 상관성을 나타내었고(p<0.001), ATAb와는 상관성이 없었다. 하시모토갑상선염에서는 TBII치는 RAIU 6시간치 및 24시간치, T3, TSH, AMAb와는 유의한 양의 상관성이 있었고(p<0.05), 혈청 T4, FT4, 갑상선글로불린 및 ATAb치와는 상관성이 없었다. 결론적으로, 그레이브스병에서는 혈청 TBII치가 갑상선기능항진증의 정도를 반영하는 소견이 되며 회복기의 TBII치는 예후를 반영하는 자료가 될 수 있다. 그리고 하시모토갑상선염에서는 비록 TBII치가 상승된 예는 많지 알지만 갑상선기능이 항진되거나 저하되는 소견의 정도와 관련이 있고 병변의 중증도를 반영한다고 볼 수가 있다.
