Adrenal cortical carcinoma is a rare disease both in adults and in children. Most of these tumors are functional, especially in children, producing endocrine syndromes such as virilization, Cushing syndrome, hyperaldosteronism or feminization. We experienced a case of adrenal cortical carcinoma in a 7yr old boy who showed features of virilization such as rapid growth rate, penile enlargement, and pubic hair. This case was diagnosed with typical hormonal findings and abdominal MRI and confirmed by pathologic findings. He was successfully treated by total left adrenalectomy and has been followed up without problem over eight months.

This paper was prepared to determine the effects of degree of initial angulation and the method of treatment toward the end results, and also to report cases of twenty-one children with a radial neck lowed up more than 12 months. The results are as follows: 1. An average follow up period was 34 months, and were ranged from 12 months to 70 months. 2. Displacement patterns of fracture were angulation in 5 cases, partial translocation in 11cases, and total displacement in 5 cases, and translocated fracture was most frequent. According to the degree of angulation, in 10 cases angulation was minor(below 30 degrees), in 8 cases moderate(30–60 degrees), and in 3 cases severe (above 60 degrees). 3. One case was treated by simple cast immobilization, 9 cases were treated by gentle closed reduction, 3 cases were by percutaneus pin reduction with K-wire, 7 cases were by open reduction and K-wires fixation, and 1 case was by closed reduction and incorporating cast immobilization. 4. The results of 20 cases were excellent in range of motion without specific complication. Without considering about the method of treatment, when angulation was severe, more time was required for recovery(Wilcoxon 2-simple test P < 0.02). When the degree of angulation was less than 60 degree, the functional recovery was faster with closed reduction than with open reduction, but with the angulation more 60 degree, there was no significant difference(Spearman correlation coefficient=0.599, P value < 0.05). In conclusion, the severity of initial displacement and the method of treatment were considered to be factors that could affect the recovery time.

Background AND PURPOSE: Status epilepticus (SE) is one of the major neurological emergency that requires immediate treatment to avoid significant morbidity and mortality. Thus, understanding the cause, features and prognosis of SE is important for the evaluation and treatment of this condition. We retrospectively reviewed the possible cause and clinical outcome of adult patients treated for SE at the Hallym Univrsity Hospital from 1994 to 1998. METHODS: For the identification of patients, we searched the data bank for patients meetinf criteria of SE who were 18 year or older, and their medical records were reviewed. We also investigated the relationships between cause, response to anticonvulsant therapy and short-term clinical outcome. RESULTS: The selected 127 patients wer 84 males and 43 females, aged 18 to 85 yeats (meen age: 49.5 years). The possible etiologies of SE were withdrawal of AED (n=27, 21.3%), anoxia (n=22, 17.3%), CNS infection (n=20, 15.7%), stroke (n=16, 12.6%), alcohol-related (n=15, 11.8%), metabolic (n=8, 6.3%), unknown (n=7, 5.5%), drug inroxicatio (n=5, 3.9%), trauma (n=4, 3.2%) and cerebral tumor (n=3, 2.4%). in 77 patients (n=77, 60.6%), SE was successfully aborted with first-line therapy, which usually included diazepam with or without phenytoin. The food responders to AEDs occurred in patients with AED withdrawal, alcohol-related, stroke, unknown, and trauma, The poor response related to anoxia, drug intoxication and CNS infection. Seventy nine patients (62.2%) had food outcome, but nineteen patients (14.9) were died. Anoxia, drug intoxication, CNS infection and metabolic abnormalities were associated with particularly poor outcome compared with other etiologies. CONCLUSION: This study indicates that the etiology of SE may help predict both the intial response to drug therapy and short-term clinical outcome.

BACKGROUND & OBJECTIVE: Magnetic resonance angiography is helpful noninvasive evaluation of intracranial arteries and, in some patients, may spare invasive angiography which has potentially serious complication. However, it's diagnostic value in vertebrobasilar artery disease has not yet been evaluated. METHODS: MRA and axial brain MRI of 47 patients with acute cerebellar and/or brainstem ischemia, 26 patients with middle cerebral artery territory infarction, and 40 age matched normal controls were reviewed. Patients wit potential risks of cardiac embolization were excluded. MR Angiography was performed by three dimensional time-of-flight gradient-echo technique. Th diagnosis of vessel stenosis was made only when the lumen diameter was reduced by less than 50% on 3-D images to avoid overestimation of MR angiography. RESULTS: Forty-seven patients had cerebellar and/or brainstem infarction: with signal hyperintensities in T2-weighted MRI sequences. Pons was the most common infarcted site(28/47), followed by medulla (17/47), and cerebellum (11/47). The sensitivity of MR angiography in detecting vascular occlusive lesions of vertebrobasilar artery was 57.5% (28/47) in cerebellar and/or brainstem infarction patients, while 7 of 26 (26.9%) in middle cerebral artery territory infarction, and 2 of 40 (5%) in age matched control subjects showed occlusion or stenosis. MR angiography detected vascular occlusive lesions more frequently on vertebral arteries (25/47, 53.2%) than basilar artery (13/47, 27.7%). And occlusive or stenotic lesions of vertebral arteries were ipsilateral to ischemic lesion sites in 12 of 17 patients(70.6%), There was no difference between deep small lacunar stroke and perforator occlusion in pons. Absence of flow void on axial T2W imaging was seen only in 9 of 47 patients (19.1%). CONCLUSIONS: The results in this present study suggest that MR angiography is moderately sensitive diagnostic tool in vertebrobasilar occlusive disease although it has limitation in detection of smaller branches occlusion. Except vertebral arteries occlusion, absence of flow void in axial MR imaging is not a reliable findings.

This study was performed to evaluate the clinical features and treatment results on 55 temporomandibular disorder patients who had treated by conservative treatment using occlusal splint. The results were as follows; 1. The ratio of men to women was about 1:2.2 and most of the patients were second and third decades. 2. Pain was the most frequent symptom, followed by clicking and mouth opening limitation. 3. The number of acute and chronic groups on the basis of 6 months duration of symptoms were similar. 4. Most of patients had Angle's Class 1 molar relationships(78.2%), followed by Class 3 and Class 2. 5. Centric Relation splints were used alone for treatment of 34 patients and 21 patients were treated with Centric Relation splints and Anterior Repositioning splints. The treatment duration of the patients who had complained pain was average 9.8 weeks and 6 patients of them had slight pain continuously during follow-up. 6. Eleven patient's maximum mouth opening who had mouth opening limitation was improved from 30.7mm to 43.0mm during procedures.

Mandibular condylar fracture is common in mandibular fractures. Unlike other facial, skeletal fractures, most of mandibular condylar neck or head fractures are treated with closed reduction and subsequent functional therapy is essential for preventing complications including ankylosis, arthrosis and growth disturbance. From January, 2000 to September, 2002, we have treated 15 cases of mandibular condylar fractures with closed reduction by using functional appliance with bite block. Among these cases, we report a case of 14-year-old female with mandibular condylar neck fracture, resulted in good clinical and radiographic progress.

Journal of Korean Academy of Conservative Dentistry 2007;32(1):37-46
The C-shaped canal system is an anatomical variation mostly seen in mandibular second molars, although it can also occur in maxillary and other mandibular molars. The main anatomical feature of C-shaped canals is the presence of fins or web connecting the individual root canals. The complexity of C-shaped canals prevents these canals from being cleaned, shaped, and obturated effectively during root canal therapy, and sometimes it leads to an iatrogenic perforation from the extravagant preparation. The purpose of this study was to provide further knowledge of the anatomical configuration and the minimal thickness of dentinal wall according to the level of the root. Thirty extracted mandibular second molars with fused roots and longitudinal grooves on lingual or buccal surface of the root were collected from a native Korean population. The photo images and radiographs from buccal, lingual, apical direction were taken. After access cavity was prepared, teeth were placed in 5.25% sodium hypochlorite solution for 2 hours to dissolve the organic tissue of the root surface and from the root canal system. After bench dried and all the teeth were embedded in a self-curing resin. Each block was sectioned using a microtome (Accutom-50, Struers, Denmark) at interval of 1 mm. The sectioned surface photograph was taken using a digital camera (Coolpix 995, Nikon, Japan) connected to the microscope. 197 images were evaluated for canal configurations and the minimal thickness of dentinal wall between canal and external wall using' Root Thickness Gauge Program' designed with Visual Basic. The results were as follows: 1. At the orifice level of all teeth, the most frequent observed configuration was Melton's Type C I (73%), however the patterns were changed to type C II and C III when the sections were observed at the apical third. On the other hand, the type C III was observed at the orifice level of only 2 teeth but this type could be seen at apical region of the rest of the teeth. 2. The C-shaped canal showed continuous and semi-colon shape at the orifice level, but at the apical portion of the canal there was high possibility of having 2 or 3 canals. 3. Lingual wall was thinner than buccal wall at coronal, middle, apical thirds of root but there was no statistical differences.
