The autoinfective filariform larva of Strongyloides stercoralis causes hyperinfection in immunosuppressed hosts. Here we report on the case of a male patient who was admitted to the emergency room at Gwangju Veterans Hospital with a complaint of dyspnea, and who was receiving corticosteroid therapy for asthma. Many slender larvae of S. stercoralis with a notched tail were detected in Papanicolaou stained sputum. They measured 269 +/- 21.2 micrometer in length and 11 +/- 0.6 micrometer in width. The esophagus extended nearly half of the body length. The larvae were identified putatively as autoinfective third-stage filariform larvae, and their presence was fatal. The autoinfective filariform larva of S. stercoralis has not been previously reported in Korea.

PURPOSE: The exercise status in patients with rheumatoid arthritis, associations between exercise behavior and personal factors, and associations between exercise behavior and exercise-specific cognitions and their effects were assessed. METHOD: Four hundred thirty nine outpatients with rheumatoid arthritis were studied. The exercise status was measured by a single item. The intensity was multiplied by the frequency and duration of each exercise. The product of these intensity values for all exercises was defined as exercise behavior. Based on the Pender's revised health promotion model, exercise benefit, barrier, self-efficacy, enjoyment and social support were chosen as exercise specific cognitions and affect variables. Path analysis was used to identify the predictors of exercise behavior. Results: Compared to the duration before being diagnosed, the number of subjects who exercised regularly increased after being diagnosed. However over half of the subjects refrain from any sort of exercise and the type of exercise is very limited. Among the variables, exercise barrier, self-efficacy, and social support were found to be significant predictors of exercise behavior, and only previous exercise experience was found to be significant predictors of all behavior specific cognitions and affect variables. CONCLUSION: These findings suggest that studies should explore exercise behaviors and strategies to emphasize the cognitive-motivational messages to promote exercise behaviors.

BACKGROUND: We evaluated the antihypertensive effect, safety and effect on serum lipids of terazosin, second generation alpha1-blocker. METHODS: Terazosin 1-4mg was adminstered once daily in 20 patients for 12 weeks with dose titration every 2 weeks. RESULTS: 1) The systolic and diastolic blood pressure were decreased from 170.0+/-13.0/104.0+/-6.0mmHg to 144.0+/-13.3/88.0+/-5.6mmHg(p<0.01), but the heart rate and body weight were independant of terazosin administration. 2) Total cholesterol was decreased significantly from 209.9+/-33.5mg/dL to 194.6+/-30.1mg/dL after 12 weeks treatment(p<0.05), triglyceride was decreased significantly from 185.4+/-37.0mg/dL to 168.9+/-35.0mg/dL(p<0.05). and LDL-cholesterol was decreased significantly from 134.5+/-31.9mg/dL to 122.7+/-29.9mg/dL(p<0.05), but HDL-cholesterol was increased significantly from 37.8+/-5.6mg/dL to 40.6+/-5.5mg/dL(p<0.05). 3) The adverse effects of terazosin were dizziness in 2, headache in 2, asthenia in 1, peripheral edema in 1 and skin rash in 1 patient, but were not troublesome enough to stop medication. CONCLUSIONS: Terazosin 1-4mg once daily regimen was effective and safe as an antihypertensive agent, and moreover terazosin has favorable effects on serum lipids.

OBJECTIVE: The informed consent, in literal sense, is a medicolegal process that requires full explanation and clear disclosure about the illness, and thorough comprehension and autonomous consent to the respective medical services of the competent recipient. The authors review the theoretical background of the informed consent and investigate pertinent problems encountered in medical practice. METHODS: We gathered 153 consecutive cases of written form of the informed consent regarding diagnosis and treatment from Mar 2001 to Jun 2002. The authors evaluate the completeness of the process by looking into the possible omitted components in whole cases and degree of recall for the explained risk by telephone questionnaire in 128 available cases. RESULTS: In a total 153 cohort, 21 emergency operation cases invariably showed structural deficiencies of free-ended discussion due to short of time. Thorough past history taking and physical examination was necessary to perform reoperation for the postoperative hematoma in 3 cases and solid intimate relationship was necessary to treat previously disclosed complication in 7 cases of invasive diagnostic and minimum operative procedures, respectively. Among the available 128 patients, only 33(25%) ones could recall the given risks addressed at the consent approximately 6 weeks later. CONCLUSION: The informed consent is a process that dictates the free dialogue between the patient and the physician, not a simple paper expressed in published characters. However, to enhance the effectiveness of the consent process, both free discussion and writing down contents are prerequisite.

PURPOSE: To evaluate the radiologic features of fibrothecoma of the ovary, which is a rare solid tumor originating from the ovarian sex cord-stroma. MATERIALS AND METHODS: The radiologic findings of 29 patients with pathologically-proven fibrothecoma of the ovary were retrospectively evaluated for bilaterality, size, shape, margin, echogenecity, CT attenuation, signal intensity on magnetic resonance imaging, calcification, and amount of ascites. RESULTS: All fibrothecomas were unilateral, and had well defined margins. The diameter of the mass was 4-18(mean, 9.6)cms. Elghteen of 29 tumors were round or oval with a smooth margin, and eleven were lobulated. The internal architecture of the tumor was purely solid in 21 patients, predominantly solid in six, and pre-dominantly cystic in two. A broad spectrum of sonographic features was apparent, including a homogeneously hypoechoic mass (with posterior shadowing in four cases, and without posterior shadowing in ten), a homoge-neously hyperechoic mass in seven cases, an anechoic mass with septatations in two, and a mixed echoic mass in six. On precontrast CT scans, the mass was isodense to the uterine myometrium in eight of nine cases, while on postcontrast scans the lesion was slightly hypodense to the myometrium in seven cases and isodense in one. On T1-weighted MR images, nine of ten cases showed a relatively homogeneous low signal intensity, while on T2-weighted images, signal intensity was homogeneously low in two patients and predominantly low with focal high intensity in seven of the other eight. On gadolinium-enhanced T1-weighted images, most tu-mors showed slight heterogeneous enhancement. Calcifications were present in two cases, and in two others there was a large amount of ascites. CONCLUSION: The characteristic finding of ovarian fibrothecomas is a well-defined, oval or lobulated homoge-neously solid mass, which on CT scans enhances less than uterine myometrium and demonstrates a predomi-nantly low signal intensity on both T1- and T2-weighted images. However, a predominantly solid mass with cystic components or a predominantly cystic mass may also be presented.

A hidden primary tumor presenting as an isolated lung mass is a diagnostic challenge to physicians because the diagnosis of lung cancer is likely to be made if the histologic findings are not inconsistent with lung cancer. A large lung mass was found incidentally in a 59-year-old man. Although adenocarcinoma was diagnosed by percutaneous needle biopsy, thyroid transcription factor-1 (TTF-1) immunostaining was negative, raising suspicion that there was another primary site. There was no abnormal finding except for the lung mass on a 18FDG-PET/CT scan and the patient did not complain of any discomfort. Finally, prostatic cancer was confirmed through the study of tumor markers and prostate-specific antigen (PSA) immunostaining. Because of the rare presentation of a single lung mass in malignancies that have another primary site, physicians should carefully review all data before making a final diagnosis of lung cancer.
