PURPOSE: This study aimed to identify the factors that impact the intention of sexual abstinence among female college students. The approach was based on Ajzen's theory of planned behavior and the parent-adolescent communication of contextual factors. METHODS: A total of 189 female university students in the first to fourth grades at two universities in Honam region participated in the study. The collected data were analyzed using hierarchical stepwise multiple regression using SPSS 21.0. RESULTS: The major factor that influences the intention of sexual abstinence among female college students was attitudes toward sexual behavior (β=0.53, p<0.001). Other factors, in descending order of their impact, were subjective norms toward friends (β=0.25, p<0.001), experience of sexual intercourse (β=−0.19, p<0.001), and subjective norms toward parents (β=0.09, p=0.040). Taken together, the aforementioned factors explained 81.1 % of the total variance. CONCLUSION: Female college students' intention to abstain from sexual behaviors requires education promoting moderate and conservative positions. The participants' subjective norms concerning sexual behaviors as perceived by friends and parents were also important. The results of this study provide meaningful implications for education of parents, sexual education of female college students, and sexual counseling programs.

Meningioma is usually known to occur stuck to the dura mater, but extradural meningioma occurs rarely. Most of the extradural meningiomas are located in the head and neck and we report a case of the primary intraosseous meningioma in the orbit. A 50-year old woman presented with the left eye hyperemia and exophthalmos. Neuroimaging modalities showed hyperostosis at the left sphenoid and orbital wall. On microscopic view, spindle cells and psammoma bodies between the woven bones were observed. The origin of the intraosseous meningioma is explained with various potent possibilities and differential diagnosis thoroughly explored.

Pleomorphic xanthoastrocytoma (PXA) has been considered as a low grade tumor of adolescents and young adults. Although this tumor often shows cystic component, the hemorrhage within the cyst is extremely rare. The authors report a rare case of cystic PXA with a hemorrhage within the cyst and the mural nodule in the left frontal lobe. A 64-year-old male presented with a week history of the right side hemiparesis. After gross total resection of the tumor, the patient was fully recovered from neurological deficit. It is suggested that this typically benign tumor could be presented with hemorrhage, causing a rapid neurological deterioration. Prompt surgical intervention, especially total removal of the tumor can provide an excellent functional recovery.

Craniovertebral junction (CVJ) tuberculosis is a rare disease, potentially causing severe instability and neurological deficits. The authors present a case of CVJ tuberculosis with atlantoaxial dislocation and retropharyngeal abscess in a 28-year-old man with neck pain and quadriparesis. Radiological evaluations showed a widespread extradural lesion around the clivus, C1, and C2. Two stage operations with transoral decompression and posterior occipitocervical fusion were performed. The pathological findings confirmed the diagnosis of tuberculosis. Treatment options in CVJ tuberculosis are controversial without well-defined guidelines. But radical operation (anterior decompression and posterior fusion and fixation) is necessary in patient with neurological deficit due to cord compression, extensive bone destruction, and instability or dislocation. The diagnosis and treatment options are discussed.

OBJECTIVE: Sonography is a noninvasive and safe bedside imaging modality that provides rapid and repeatable real-time radiological evaluations without a radiation hazard. However, sonography has not gained widespread acceptance as a diagnostic tool in adult brain disease because of limited imaging resolution through the bony window. We investigated the diagnostic potential and clinical usefulness of bedside brain sonography through surgical bone defects in neurosurgical patients. METHODS: We evaluated twelve patients, each of whom had undergone a decompressive craniectomy, via bedside sonography, and performed comparison CT or MRI for all patients. RESULTS: We obtained reliable information regarding anatomical structure displacement, ventricle systems, intracranial fluid collection, presence and distribution of cerebral infarctions, and hemorrhages. We performed several interventional trials under sonography guidance, including aspiration of entrapped fluid collection and insertion of an external ventricular drainage catheter into a collapsed and displaced ventricle cavity. CONCLUSION: Bedside sonography through surgically created bone defects is a non-invasive method that physicians can repeat as required with no radiation hazard, and it is of particular value in emergent and critical situations when conventional neuroimages are unobtainable. Bedside sonography can be a first-line monitoring tool, in lieu of CT, for critically ill patients with surgical cranial defects.

BACKGROUND/AIMS: This study investigated the clinical features and prognosis of primary biliary cirrhosis (PBC) in Korea. METHODS: Clinical data of patients diagnosed as PBC between 1997 and 2008 at eight referral hospitals were analyzed retrospectively. PBC was diagnosed based on liver function tests, presence of serum antimitochondrial antibody (AMA), and histopathological findings. RESULTS: In total, 251 patients (218 females, 33 males; mean age 54 years) were enrolled, and the mean follow-up duration was 33.5 months. At the diagnosis, 61% of the patients were asymptomatic, 12% had decompensated liver cirrhosis, and 98% were positive for AMA. The serum alkaline phosphate (ALP) level was 2.6 times the upper limit of normal, aspartate aminotransferase was 105 U/L, and bilirubin was 2.0 mg/dL. The mean Mayo risk score was 5.5, and the Child-Pugh class was A, B, and C in 79%, 19%, and 2% of the patients, respectively. Ursodeoxycholic acid (UDCA) was used for treatment in 88% of the patients, among which 70% exhibited biochemical responses defined as normalization or a >40% decrease in ALP at 6 months. Eight deaths occurred during the follow-up; the causes were variceal bleeding, hepatic failure, and sepsis. The overall 5-year survival rate was 95%. The poor prognostic factors were being older than 60 years, high bilirubin, low albumin, ascites, high Mayo risk score, Child-Pugh class C, and initial presence of hepatic decompensation. CONCLUSIONS: Most patients diagnosed as PBC were asymptomatic, and these patients had a favorable short-term prognosis. The prognosis of PBC was dependent on the initial severity of liver disease.

Endobronchial lipomas are rare benign tumors that arise from the lung. They partially or totally obstruct the bronchial lumen, producing a variable degree of collapse, irreversible bronchiectasis, and pulmonary damage. Although bronchoscope, CT and MR are reported to be helpful in establishing the diagnosis, CT is highly specific and sensitive in detecting fatty tumor. They may be removed by endoscope or thoracotomy or lobectomy. We present a case of endobronchial lipoma completely obstructing the right middle lobe and postobstructive irreversible pulmonary change with review of literatures.

Talc pleurodesis is a safe and effective treatment for a recurrent malignant pleural effusion. However, acute hypoxemia, pulmonary edema or acute respiratory failure can develop in a small number of patients. We report 2 patients who developed fatal hypoxemia after talc pleurodesis which was necessary the control recurrent pleural effusion. The first case was an 18-year old male diagnosed with Ewing's sarcoma with bilateral lung metastases and pleural effusion. The performance status was ECOG (Eastern Cooperative Foncology Group) grade 3. Fever along with hypoxemia and leukocytosis developed 10 hours after the second talc pleurodesis on the right side for an uncontrolled pleural effusion, The patient died from respiratory failure after 13 days. The second case was a 66-year old female diagnosed with non-small cell lung cancer with a bone metastasis. Two weeks after systemic chemotherapy, she complained of dyspnea, and a pleural effusion was observed on the right side. Her performance status was ECOG grade 3. Talc pleurodesis was performed for recurrent pleural effusion, but hypoxemia developed 6 days after pleurodesis and she died from respiratory failure 10 days after pleurodesis. In conclusion, talc pleurodesis should be performed very carefully in patients with a poor performance status, in cases with repeated pleurodesis, bilateral pleural effusion, recent chemotherapy, radiotherapy and when there are parenchymal metastatic lesions present.

PURPOSE: The visual performance of pseudophakic eyes depends on the type of intraocular lenses (IOLs) that are implanted. Aspherical and multifocal IOLs have recently been developed to improve visual quality after cataract surgery, but multifocal IOLs can be associated with decreased contrast sensitivity (CS), halos, and glare. This study compares the visual performance of monofocal and multifocal IOLs by measurement of higher-order aberrations (HOAs) and CS values. MATERIALS AND METHODS: HOAs and CS values of 42 eyes with implanted monofocal IOLs and 40 eyes with implanted multifocal IOLs were measured preoperatively and more than 6 months after surgery. In the multifocal IOL group, HOAs and CS values were also measured with addition of a trial lens of -0.5 diopter (D) to evaluate the compensatory effect on spherical aberration. RESULTS: CS values of the multifocal IOL group were significantly lower than those of the monofocal IOL group for all spatial frequencies tested (p<0.01), and the spherical aberration was significantly higher in the multifocal IOL group than in the monofocal IOL group (p<0.001). Addition of a -0.5 D lens to the multifocal IOL group decreased the difference in CS between the two groups (p=0.003). CONCLUSION: Increased spherical aberration may contribute to lower CS in the multifocal IOL group. In such cases, CS can be improved by addition of a -0.5 D lens to compensate for the spherical aberration.
