Doppler sonography has been introduced to evaluate uterine and ovarian diseases. It has been reported to be used to distinguish benign from malignant adnexal masses. The purpose of this study was to assess the blood flow characteristics of adnexal masses and to determine the optimal cut-off points for the Doppler indices obtained, resistance index and pulsatility index, to best differentiate benign from malignant lesions. We performed pulsed Doppler ultrasound in seventy-eight adnexal masses between February 1989 and June 1994. The pulsatility and resistance index were calculated from the waveforms generated from blood flow within the ovary. There were 51 benign and 27 malignant histologically proved ovarian lesions. All women have been operated on. The results were as follows ; Benign tumors and cysts had a significantly higher pulsatility index(mean, 1.23+/-0.74; range, 4.46-3.36) and resistance index(mean, 0.64+/-0.19; range 0.34-1.43) than did malignant tumors(pulsatility index : mean, 0.87+/-0.49; range, 0.31-2.27; resistance index : mean, 0.50+/-17; range, 0.23-0.8). However, some overlap in individual values for benign and malignant lesions was found. In conclusion, our data suggest that high pulsatility and resistance indices may indicate benign adnexal masses ; however, considerable overlap in pulsatility and resistance indices between benign and malignant lesions were noted, and further work will be needed before the validity of these factors is proved.

PURPOSE: The present study was performed to evaluate the changes in tear film and ocular surface parameters after using sodium hyaluronate (SH) 0.1% alone or in combination with cyclosporine A (CsA) 0.05% in patients with thyroid-associated ophthalmopathy accompanied by dry eye. METHODS: A total of 72 eyes from 36 patients were divided into two groups; 36 eyes of 18 patients were treated with 0.1% SH alone (group 1), and 36 eyes of 18 patients were treated with SH 0.1% and CsA 0.05% (group 2). Tear break-up time (BUT), basal tear secretion test (BST), tear clearance rate (TCR), fluorescein staining (FS) and corneal sensitivity test (CST) were evaluated at pre-treatment and one, three and six months post-treatment. Conjunctival impression cytology was performed and tear CXCL11 (Chemokine (C-X-C motif) ligand) levels were measured pre-treatment and three months post-treatment. RESULTS: BUT, BST, TCR, KEP and CST were significantly improved at six months in group 1 (p < 0.05) and at three months in group 2 (p < 0.05). The degree of conjunctival squamous cell metaplasia, goblet cell density and tear CXCL11 levels were significantly changed at three months in group 2 (p < 0.05). However, there were no significant changes in group 1 after 3 months. CONCLUSIONS: Combined use of topical 0.1% SH and 0.05% CsA can result in early improvement in tear films and ocular surface parameters in patients with thyroid-associated ophthalmopathy accompanied by dry eye.

An isolated blow out fracture of the medial orbital wall is uncommon, where as the incidence of conjugation with an orbital floor fracture is high. Clinically, they are suspected when periorbital trauma is associated with epistaxis, orbital hematoma, subcutaneous emphysema and horizontal diplopia. Surgical intervention is indicated if the fracture cause impairment of ocular motility, diplopia and enophthalmos due to incarceration of medial rectus muscle and soft tissue. Recently, endoscopic surgery in the treatment of orbital wall fracture instead of external approach has been introduced. The authors performed endoscopic intranasal ethmoidectomy with release of the rectus muscle in two patients with medial orbital wall fracture on the first post-traumatic day in one and the thirteenth day in the other and have good result.

To evaluate the implication of vascular factor in normal tension glaucoma, authors performed color doppler imaging[CDI] for ophthalmic artery, central retinal artery and posterior ciliary artery in 21 eyes of 12 patients in normal tension glaucoma and 16 eyes of 11 patients in normal control group. We compared peak-systolic velocity[PSV], end-diastolic velocity[EDV], mean velocity[MV], resistance index[RI] and pulsatile index[PI] between the two groups. We evaluate the difference in parameters according to age, sex, systolic and diastolic blood pressure, past history of diabetes and hypertension, cup-disc ratio and visual field change. In normal tension glaucoma group, PSV, EDV and MV of ophthalmic artery and central retinal artery were significantly decreased and pulsatile index was significantly increased compared to those of normal group. Resistance index was also increased in normal tension glaucoma group, but statistically not significant. All parameters of posterior ciliary artery had no significant difference between the two groups. Age was related positively to pulsatile index and resistance index of central retianl artery and diastolic blood pressure was related positively to resistance index of ophthalmic artery. Cup-disc ratio was related negatively to PSV and EDV of ophthalmic artery. Above results imply that blood flow velocity decreased by increasing resistance factor in normal tension glaucoma, therefore local vascular factor might be related to the development of the normal tension glaucoma and affected by age, blood pressure and cup-disc ratio change.

Ovarian mucinous cystadenoma of borderline malignancy was consisted of intestinal mucinous cystadenomas of borderline malignancy and Mullerian mucinous papillary borderline tumors. Mullerian mucinous papillary tumors was lined by mucinous epithelium of endocervical type and characterized by papillae architecturally similar to those of serous borderline tumors. These tumors have clinical and pathologic differences from those of intestinal mucinous cystadenomas of borderline malignancy.We report a case of ovarian Mullerian mucinous papillary cystadenomas of borderline malignancy with review of literature.

Pituitary carcinomas are rare primary adenohypophyseal tumors with cerebrospinal or extracranial metastasis. The present case, the first report of the disease in Korea, involved a 36-yr-old woman who presented with a 3-week history of headache. Brain magnetic resonance imaging revealed a 2.5-cm sellar and suprasellar mass showing heterogeneous enhancement with suspicious invasion of both cavernous sinuses. The patient underwent gross-total resection. The tumor cells were composed of polygonal cells singly or in variable-sized nests. The nuclei were large and round with prominent nucleoli. The cytoplasms was acidophilic and granular. Marked pleomorphism and frequent mitoses (3 per 10 HPFs) were found. By immunohistochemistry, tumor cells were strongly positive for prolactin, but negative for ACTH and GH. Additional immunostainings for cytokeratin, vimentin, and glial fibrillary acidic protein (GFAP) were negative. After the surgery, the patient received radiotherapy because of the atypical histologic features. The prolactin level fell from 123.17 ng/mL to 5.17 ng/mL after surgery. Nine months after the initial diagnosis, the patient died from mandibular metastasis associated with the pituitary carcinoma.

Paragonimiasis is a parasitic infection that occurs following the ingestion of infectious Paragonimus metacercariae, which occurs as a result of eating raw or undercooked freshwater crabs or crayfish. Pulmonary paragonimiasis is the most common clinical manifestation of this infection. Human paragonimiasis occurs sporadically. We experienced a case of pulmonary paragonimiasis in a 35-year-old woman with left lower chest pain. The patient had hypereosinophilia and a pleural effusion. The diagnosis was confirmed by positive ELISA (Enzyme-linked immunosorbent assay) that detected Paragonimiasis westermani antibody in the serum. We treated the patient with praziquantel for two days at a daily dosage of 75 mg/kg. Left pleuritic pain and pleural effusion improved after treatment. However, similar symptoms and pleural effusion developed recurrently for the first 3 courses of treatment with praziquantel. Upon the fourth round of treatment, the patient made a full recovery.

BACKGROUND AND OBJECTIVES: Diffuse coronary artery disease presents physicians with a therapeutic challenge. The results after the use of bare metal stents (BMS) are limited by the high rate of restenosis. The introduction of drugeluting stent (DES) has prompted interventional cardiologists to treat long diffuse lesions with multiple overlapping stents. The purpose of this study is to determine the safety and efficacy of using multiple overlapping DESs for patients with diffuse coronary artery disease. SUBJECTS AND METHODS: From Jan. 2002 to Dec 2004, 83 consecutive patients suffering with diffuse coronary artery disease who underwent stent implantation with a minimum of 50 mm long BMSs or DESs were analyzed. The patients who had overlapping stents for dissection without diffuse lesion or they had BMS with overlapping DES were excluded from the study. The patients were divided into two group, the BMS group (group I: 29 patients, 63.0+/-8.2 years) and the DES group (group II: 56 patients, 60.6+/-9.3 years). The major adverse cardiac events (MACE), including death, myocardial infarction (MI), target vessel revascularization (TVR) and coronary artery bypass grafting (CABG), were examined. RESULTS: The mean number of stents implanted was 2.19+/-0.4 in group I and 2.08+/-0.2 in group II, whereas the total mean length of the stents was 61.5+/-9.3 mm in group I and 61.4+/-9.1 mm in group II (p=NS). Procedural success was achieved for 89.7% of the patients in group I and for 96.3% of the patients in group II. No acute stent thrombosis was observed in both groups. All the patients underwent clinical follow-up (mean follow-up: 15+/-8.9 months, range: 7-36 months), and 66.2 % had an angiographic follow-up done at six months. During the follow-up, MACE was the cause of two deaths; there were thirteen TVRs and one CABG in group I, and there was one MI and five TVRs in group II. The TVR rate was lower in group II compared with group I (44.8% vs. 9.3%, respectively; p<0.001). Late stent thrombosis developed for one patient in group II. CONCLUSION: The implantation of overlapping DESs in patients with diffuse coronary artery disease is safe and this treatment is associated with better clinical outcomes than that with using BMS.

BACKGROUND AND OBJECTIVE: Assessment of quality of life (QOL) of patients with chronic illness requires reasonable tools which reflect the patients' cultural and behavioral properties. We developed the quality of life questionnaire for adult Korean asthmatics (QLQAKA) on the basis of the Korean life style and evaluated its reliability and validity. METHODS: The QLQAKA consisted of four domains; symptoms (six items), daily activity (five items), emotion (three items) and reaction to environmental stimuli (three items). Patients answered each item according to a five-response scale. The reproducibility and validity of the questionnaire was estimated from the responses of 244 patients who visited the clinics in 15 institutes within a 2-week interval. RESULTS: Items with the most frequent complaints were dyspnea (87%), difficulty in sputum discharge or throat clearing (87%), limitation in strenuous activity (84%) and coughing (82.4%). The QLQAKA reflected the changes of patients' status very well. The value of minimal important differences, such as the clinically significant minimal change in the QOL score, was 0.5. The questionnaire was also highly reproducible with the value of intraclass correlation coefficiency and intraclass standard deviation as 0.940 (p<0.001) and 0.180, respectively. The changes of mean total QLQAKA score correlated weakly with the changes of FEV1 and PEFR values. CONCLUSION: The adult version of QLQAKA was valid and may be a reproducible tool for evaluating and monitoring Korean adult asthma patients.
