The purpose of this study was the long-term clinical and radiological evaluation of conservatively treated condylar fractures in children. This study was therefore undertaken to analyze the long-term effects of treating condylar fractures in children with conservative therapy in order to resolve the controversial question of whether complete remodeling occurs in this age or, if not, whether it is more likely to be associated with certain types of fracture or with other factors. This study was based on a series of 11 consecutive children and adolescents, aged between 3 and 15 years, with fractures of the condylar process who had been treated with conservative therapy at the Department of Oral & Maxillofacial surgery, Inha University Hospital, Inchon, Korea. All patients underwent a clinical investigation with special emphasis on Temporomandibular joint function and facial asymmetry. The patients also underwent a radiologic investigation, focusing on fracture remodeling and symmetry of mandible. It consists of panoramic radiograph, PA & lateral cephalogram and 3-D CT. No patient described impaired temporomandibular joint(TMJ) function or pain on the affected side. 2 of 8 (25%) unilateral and 1 bilateral fractures show slight facial asymmetry. Despite apparently excellent recovery of function, there were marked remodeling changes evident on the CT scan. Such changes are not usually evident on panoramic radiograph. Radiologic investigation showed incomplete remodelling(54.5%) and asymmetry of the mandible (27.3%) in some patients. Conservative treatment of condyle fracture in children results in satisfactory long-term outcome of jaw function despite a relative high frequency of radiologically noted aberrations.

Active straight-leg raise (ASLR) is a physical evaluation procedure to test lumbar spine stability. Several previous studies have reported various methods to control the activation of abdominal muscles during ASLR. We investigated the effects of three different hip positions in frontal plane on abdominal muscles to increase or decrease the difficulty level of lumbar spine stability exercise during ASLR in pain free subjects. Eleven young and healthy subjects voluntarily participated in this study (6 men, 5 women; mean age=$24.0{\pm}1.2$ years, height=$160.0{\pm}7.3cm$, weight=$55.0{\pm}10.6kg$, body mass index=$21.5{\pm}2.3kg/m^2$). The subjects had three trials on each ASLR with hip $10^{\circ}$ adduction, neutral hip, and hip $30^{\circ}$ abduction. Separate repeated-measures analysis of variance (ANOVA) and the post hoc Bonferroni tests (with ${\alpha}$=.05/3=.017) were performed for each muscle among the three different hip positions in frontal plane (ASLR with hip $10^{\circ}$ adduction, neutral hip, and hip $30^{\circ}$ abduction). The ipsilateral external oblique (EO), contralateral EO, ipsilateral internal oblique/transverse abdominis (IO/TrA), and contralateral IO/TrA were significantly greater in ASLR with hip $30^{\circ}$ abduction compared with ASLR with hip $10^{\circ}$ adduction. Also, the ipsilateral EO, contralateral EO, and ipsilateral IO/TrA were significantly greater in ASLR with hip $30^{\circ}$ abduction compared with ASLR with neutral hip. These results suggest that ASLR with hip $30^{\circ}$ abduction and neutral would be useful method to strengthen the EO and IO/TrA. And, ASLR with hip $10^{\circ}$ adduction would be effective in early stages of lumbar stabilization program due to low activation of EO and IO/TrA during maintaining of ASLR position with low load.

Objective: Leejung-tang (Rechu-to in Japanese) is a traditional Korean herbal formula used for treatment of gastrointestinal disorders such as vomiting, stomach pain, chronic gastritis and gastrointestinal ulceration. The present study was carried out to investigate the potential acute toxicity of Leejung-tang water extract (LJT) by a single oral dose in Crl:CD (SD) rats in compliance with current guidelines. Methods: In the preliminary study, there were no adverse effects such as death, clinical signs, and body weight changes at dose levels of 500, 1000, and 2000 mg/kg/day body weight. Based on the results, a dose of 2000 mg/kg was selected as the toxicological limited dose. LJT was administered once by gavage to male and female rats at dose levels of 0 and 2000 mg/kg bodyweight. During the study period, mortalities, clinical findings, and body weight changes were observed for 14 days following the administration. On day 14 after the treatment, the animals were sacrificed by carbon dioxide overdose and complete gross postmortem examinations were performed. Results: In present study, no treatment-related deaths were observed. There were no adverse effects on clinical signs and body weight changes. In addition, there were no observed gross findings in all groups except for a kidney cyst in the 2000 mg/kg/day female group. Conclusion: The results indicated that LJT did not induce toxic effects at a dose level up to 2000 mg/kg in rats and its median lethal dose ($LD_{50}$) was considered to be over 2000 mg/kg/day body weight for both genders.

A sclerosing stromal tumor of the ovary is an extremely rare benign tumor; it usually is found during the second and third decades of life. Patients present with pelvic pain or a palpable abdominal mass. Hormonal effects such as masculinization are uncommon. Here, an 11-year old premenarchal girl presented with deepening of the voice. In addition, clitoromegaly and hirsutism with a male suprapubic hair pattern were observed. The laboratory findings showed that the testosterone level was elevated to 3.67 ng/ml, andostenedione to above 10 ng/ml, dehydroepiandrosterone-sulfate to 346 ${\mu}g$/dl and 17-hydroxy progesterone (17-OHP) to 11.28 ng/ml. The chromosome evaluation revealed a 46,XX female karyotype. An adrenocorticotropic hormone stimulation test was performed. The 17-OHP to cortisol ratio in 30 minutes was 0.045, which suggested a heterozygote for the 21-hydroxylase deficiency. However, the CYP21A2 gene encoding steroid 21-hydroxylase showed normal. The pelvic ultrasound showed a heterogeneous mass consisting of predominantly solid tissue in the pelvic cavity. The pelvic magnetic resonance imaging revealed an $8.9{\times}6.2{\times}6.6$ cm mass of the left ovary. A left oophrectomy was performed and microscopic examination confirmed a sclerosing stromal tumor. Immunohistochemical studies showed that the tumor was positive for smooth muscle actin and vimentin, but negative for S-100 protein and cytokeratin. Following surgery, the hormone levels returned to the normal range and the hirsutism resolved.

The methods of clinical applications of the foot as a free-flap donor site includes microvascular toe-to-finger transfer, free neurovascular flap transfer, first web space flap transfer, and osteocutaneous free flap transfer. We have evaluated the results of treatment for 35 patients to be undergone a microvascular reconstructive procedure with the foot as a donor site from January 1982 to June 1996. The performed operations were 16 cases of thumb reconstruction with wrap around procedure, 3 cases of tenocutaneous flap transfer, 10 cases of dorsalis pedis flap transfer, 2 cases of first web space free flap and 4 cases of toe-to-finger transfer. The follow up study was 69 months in average. Regarding to the various donor sites, morbidity was divided into five different categories: Cosmesis, Functional loss, Sensory loss, Wound complication, and Pain. According to the results of examination(35 patients), the results was excellent(25), good(9), fair(1), and poor(0). Among the categories, morbidity was higher at cosmesis. The patients under 50 years were better outcome. Among the operative methods from the foot as a donor site, thumb reconstruction with wrap around procedure showed poorest outcomes. So, We conclude that the foot as a free flap donor site is a good source for the microvascular reconstructive surgery. But, Preoperative donor site evaluation, adequate operative technique and post operative management are essential to decrease the morbidity of donor site.

A 61-year-old male who complained of right upper quadrant pain was referred to the authors for evaluation after his computed tomography suggested biliary adenocarcinoma. The lesion consisted of multiple cysts with papillary mass and peri-ampullay mass. The patient underwent an operation due to a clinical suspicion of biliary cystadenocarcinoma, but the pathology confirmed biliary papillomatosis (BP) after diagnosing intrahepatic papillary neoplasm with high-grade dysplasia and invasive adenocarcinoma with papillary neoplasm from the distal common bile duct to the duodenum. BP is a disease characterized by multiple papillary masses. Its cause has yet to be discovered. It commonly manifests as bile duct dilation but rarely as a ductal cystic change. Under computed tomography or magnetic resonance imaging, both the BP and the cystic neoplasm can show bile duct dilation and a papillary mass, which makes their differential diagnosis difficult. A confirmative diagnosis can be made through a pathologic examination. BP is classified as a benign disease that can become malignant and may recur, though rarely. Its treatment of choice is surgical resection. Laser ablation or photodynamic therapy can be used for unresectable lesions. In the case featured in this paper, biliary papillomatosis was difficult to differentiate from cystic adenocarcinoma due to diffusely scattered multiple large cystic lesions in the liver, and it was histologically confirmed to have become malignant with cystic duct dilation after the operation. This case is reported herein with a literature review.

Background: Acceptability of self-sampling HPV testing is confirmed worldwide. However, some cultural differences may affect this question. Therefore, this study was conducted to evaluate the acceptability of self-sampling HPV testing in Thai women. Materials and Methods: One hundred women aged 30-65 years with an intact cervix were included in this study. The participants were asked to do the Pap test by physicians and then brush type self-sampling instruments were assigned for self-collection and finally completed a questionnaire for acceptability evaluation. The questionnaire contains 2 parts. Part one covered general information of the participants and part two is the acceptability questions. Results: Mean age was 40.6 years. The incidence of high risk HPV detection in this study was 16%. The most common reason for doing Pap smear was for annual checkup. On the topic of ease of use, 85 % of the subjects agreed. Most of the participants (82%) reported that they felt less pain. However, reliability of the result was not satisfactory because 37% of the participants hesitated to rely on the results of the test. According to the price, if the price is less than 1,000 Baht (32.59 Baht = 1USD), 82% of the subjects would use it for their next screening. Conclusions: The acceptability of self-sampling device in this study is quite good but the reliability of the test was questioned by some of the participants. Moreover, the price of the test in Thailand may also influence the acceptability of the test.
