Arotinolol, a now alpha and beta bloking agent, was administered orally in 32 hypertensive patients for 8 weeks in order to evaluate the antihypertensive effects and side effects. The doses were from 20mg to 30mg a day. The serum chemistries and chest X-ray were taken before and after Arotinolol administration. The results were as follows; 1) Blood pressure which was measured in sitting, supine and standing position was 176.37+/-4.73/116.54+/-4.34, 170.14+/-5.35/103.12+/-3.67, 156.37+/-7.54/104.31+/-3.34mmHg in control and 144.63+/-2.78/94.41+/-2.87, 146.47+/-5.41/89.12+/-4.34, 140.71+/-4.47/89.73+/-3.71mmHg in the treatment group. The differences between both blood pressure were statistically significant(P<0.001). 2) There was no significant change in pulse rate before and after medication. 3) There was no significant change in the laboratory findings such as CTR, GOT, GPT, alkaline phosphatase, CPK, creatinine, BUN, uric acid, cholesterol, fasting blood sugar and triglyceride before and after treatment. 4) The side effects of arotinolol were observed in 6 of 32 cases(18.7%), which were not required discontinuing the medication or decreasing the dose.

A 47-year-old male with hypertension, diabetes mellitus and heavy smoking, but no anginal symptoms, presented with claudication of the lower extremities. Extremity angiography with coronary angiography revealed peripheral arterial lesions including a left subclavian artery occlusion with coronary artery disease. The patient underwent an initial off-pump coronary artery bypass with an ascending aorto-axillary bypass. The right internal mammary artery was anastomosed to the left anterior descending coronary artery. The greater saphenous vein graft was connected from the ascending aorto-axillary bypass graft to the diagonal branch. At postoperative day 18, femorofemoral and bilateral femoropopliteal bypasses were performed. We report a case of the combined repair of coronary artery disease and a left subclavian artery occlusion.

A 76-year-old woman with a history of chest pain and palpitation, was diagnosed with bilateral coronary to pulmonary artery fistulae with a concomitant saccular aneurysm, which is quite rare. Suture closure of the fistular vessels around the pulmonary artery root, the removal of a saccular aneurysm, and the transpulmonary closure of coronary to pulmonary artery fistulae were performed. The patient was well at 4 months after surgery.

PURPOSE: To report the clinical outcome of children with unilateral high myopic anisometropic amblyopia who were treated with contact lenses (CL). METHODS: Patients who had myopic anisometropia greater than -7 diopters and was treated with contact lenses combined with occlusion therapy during the period between 1998 and 2007 were retrospectively reviewed. Twenty-seven patients who were followed up for more than 1 year after treatment were included in the study. Initial and final best corrected visual acuities (BCVA) were compared and factors which influence the visual outcome were analyzed. RESULTS: A total of 10 out of 27 patients (37%) acquired visual improvement of more than 2 lines. At the final examination, 6 patients (22.2%) had BCVA better than logMAR 0.3 and 10 patients (37.0%) had BCVA better than logMAR 0.7. Medullated nerve fiber and strabismus were the most commonly associated ocular pathologies among the patients. Patients without strabismus or medullated nerve fiber acquired greater visual improvement than patients with these comorbidities. Patients with lower initial refractive error (spherical equivalent) in the amblyopic eye acquired a better final vision. Poor compliance to CL wearing or occlusion therapy adversely affected the final vision. CONCLUSIONS: In the present study of children with unilateral severe myopic anisometropic amblyopia treated with CL combined with occlusion therapy, a third of the patients acquired visual improvement of more than 2 lines. The absence of medullated nerve fiber or strabismus was determined to be a good prognostic factor.

Hypoglycemic effects of exo-biopolymers (EBP) produced by submerged mycelial cultures of Coriolus versicolor, Cordyceps sinensis, Paecilomyces japonica, Armillariella mellea, and Fomes fomentarius were investigated in streptozotocin (STZ)-induced diabetic rats. The rats from each experimental group were orally administered with EBPs (100 mg/kg BW) daily for 2 weeks. Though the hypoglycemic effect was achieved in all the cases, however, C. versicolor EBP proved as the most potent one. The administration of the C. versicolor EBP substantially reduced (29.9%) the plasma glucose level as compared to the saline administered group (control). It also reduced the plasma total cholesterol (TC), triglyceride (TG), aspartate aminotransferase (AST) and, alanine aminotransferase (ALT) levels by 9.22, 23.83, 16.93, and 27.31%, respectively. The sugar and amino acid compositions of this EBP were also analyzed in detail.

PURPOSE: The purpose of this study was to prospectively evaluate the detectability and usefulness of automated whole breast ultrasound (AWUS) and to compare it with handheld breast ultrasound (HHUS) in cases with suspicious microcalcifications identified by mammography. METHODS: Forty-two patients with 43 suspicious microcalcifications (25 malignant and 18 benign) detected by mammography underwent AWUS, HHUS, and histol-ogic examination. With knowledge of the mammographic findings, HHUS was performed to assess the visibility of the microcalcifications and the presence of associated masses or ductal changes. Two radiologists reviewed the AWUS images in consensus using the same methods employed for HHUS. Detectability of AWUS was compared with that of HHUS and was correlated with histologic and mammographic findings. RESULTS: Of the 43 lesions, 32 (74.4%) were detectable by AWUS and 31 (72.1%) by HHUS. No significant differences in sensitivity were found between the two methods (p=0.998). AWUS detected 96% (24/25) of malignant microcalcifications and 44.4% (8/18) of benign microcalcifications. AWUS was more successful in the detection of malignant vs. benign lesions (96.0% vs. 44.4%, p=0.002), lesions >10 mm vs. ≤10 mm in size (86.7% [26/30] vs. 46.2% [6/13], p=0.009), lesions with a fine pleomorphic or linear shape vs. a round or amorphous or coarse heterogeneous shape (94.7% [18/19] vs. 58.3% [14/24], p=0.021), and lesions associated with a mass or architectural distortion vs. without obvious changes on mammography (100% [19/19] vs. 54.2% [13/24], p=0.022). CONCLUSION: Detectability of AWUS was comparable to that of HHUS in cases where suspicious microcalcifications were identified on mammography. Therefore, AWUS might be helpful in the performance of ultrasound-guided percutaneous procedures for highly suspicious microcalcifications.

PURPOSE: To evaluate the long-term visual outcomes and complications of cataract surgery in eyes previously treated for retinoblastoma. METHODS: We reviewed the medical records of patients who underwent cataract extraction and intraocular lens implantation at Seoul National University Children's Hospital for a secondary cataract that developed after retinoblastoma treatment. RESULTS: During the period between 1990 and 2014, 208 eyes of 147 patients received eye-salvaging treatment (radiotherapy, chemotherapy, and local therapy) for retinoblastoma at Seoul National University Children's Hospital. Among these eyes, a secondary cataract was detected in 17 eyes of 14 patients, and five eyes of five patients underwent cataract surgery. The median age of cataract formation was 97 months (range, 38 to 153 months). The medial interval between the diagnosis of retinoblastoma and cataract formation was 79 months (range, 29 to 140 months). All patients received posterior chamber intraocular lens insertion after irrigation and aspiration of the lens through a scleral tunnel incision. Anterior vitrectomy and posterior capsulotomy were performed in two eyes and a laser capsulotomy was subsequently performed in one eye. No intraoperative and postoperative complications occurred. The median follow-up after surgery was 36 months (range, 14 to 47 months). The final best corrected visual acuities were improved in all five eyes. No intraocular tumor recurrences or metastases occurred. CONCLUSIONS: After retinoblastoma regression, cataract extraction in our series was not associated with tumor recurrence or metastasis. Visual improvement was noted in every patient.

PURPOSE: In order to investigate the incidence of relative afferent pupillary defect (RAPD) in normal adolescence and if there is any interocular difference in the case with RAPD. METHODS: Fifty-eight adolescence in 14 to 36 years of age who showed normal findings on measurement of visual acuity, intraocular pressure, slit lamp examination, and funduscopic examination except refractive errors underwent swinging flashlight test and infrared pupillography. The case with RAPD further underwent optical coherence tomography, color vision test, Humphrey visual field test, and Bryngelson test (hole-in-the-card test). RESULTS: One out of 58 cases, in whom more pronounced myopic astigmatism and lower mean deviation on Humphrey visual field test within normal limits were found, showed RAPD in the dominant right eye with swinging flashlight test and infrared pupillography. CONCLUSIONS: The incidence of RAPD in normal adolescence was 1.7%. Myopic astigmatism was higher in the eye with RAPD.

PURPOSE: This study was aimed at determining whether a regular follow-up of patients with colorectal cancer can lead to improved re-resectability, and which test is useful for detecting a resectable recurrence. METHODS: The medical records of 397 consecutive patients, who underwent a curative resection for colorectal cancer between January 1996 and December 2000, with a mean follow-up of 36 months, were retrospectively analysed. RESULTS: The overall recurrence rate was 19.6%, with 22.5% and 7.8% in the regular and irregular follow-up groups (P=0.002), respectively. There was a significant difference in the asymptomatic recurrence detection rate (68.1 vs. 16.7%; P=0.021), but a curative intent reoperation was possible in 21 (29.1%) of those patients with a cancer recurrence in the regular follow-up group, and in 1 (16.7%) inform the irregular follow-up group, which was not significantly different (P= 0.454). Careful history taking and a physical examination were beneficial in the detection of a resectable recurrence. Serum carcinoembryonic antigen determination and endoscopy were useful for detecting a recurrence (14 cases and 5 cases, respectively), and of these 4 (28.6%) and 5 cases (100%) could be treated with a curative intent reoperation, respectively. Abdominal CT, or MRI, and a chest radiography were also useful for detecting a recurrence (22 cases and 8 cases, respectively), but the curative intent reoperation rates were slightly low (3 cases (13.6%) and 1 case (12.5%), respectively). CONCLUSION: A regular follow-up after a curative resection for colorectal cancer, although facilitating detection of recurrence before symptoms developed, was unlikely to succeed in increasing the rate of a curative reoperation.
