The fine needle aspiration (FNA) cytologic findings in 16 cases of histologically confirmed thymoma are reported. The aspirates were obtained under fluoroscopic guidance. The cytologic diagnoses were inadequate sample in one case, thymoma in 12 (75%), small cell carcinoma or thymoma in 1, benign mesenchymal tumor in 1, and germ cell tumor in one. The cytologic features were detailed according to the constituent epithelial cell type, and to the ratio of epithelial cells and lymphocytes. Fifteen cases were classified into 4 small epithelial cell type, 6 intermediate epithelial cell type, 1 large epithelial cell type, 1 large pleomorphic epithelial cell type, and 3 spindle-shaped epithelial cell type. Cytologic differential diagnosis was discussed, and the important criteria for the cytologic diagnosis of thymoma were reviewed. This review leads us to think that nonoperative cytologic approaches in the diagnosis of the thymoma are possible, and that correct cytologic diagnosis of thymoma with FNAs can easily be made, if adequate samples are obtained. However, the invasiveness and histologic type could not be predicted by cytological features only. Knowing various cytologic and histologic features of thymoma will be helpful for the diagnosis of thymoma and the differential diagnosis of mediastinal tumors.

A retrospective study on computed tomographic (CT) findings in 35 surgically confirmed cases of common bile duct stones was performed to analyze the characteristic CT findings. Choledocholithiasis was correctly diagnosed by CT in 33 our of 35 cases(sensitivity, 94.3%) and among these CT demonstrated calculi of high attenuation in 32 and of soft tissue density in one case. The thirty two included 23 totally calcified, 5 rim calcified and 4 laminated stones. The target sign was observed in 30 out of 33 CT positive cases (90.1%). We concluded that CT is an accurate modality in the diagnosis of common bile duct stones with its' reliable display of the calcified or the laminated stone itself and its' characteristic target sign.

Obesity is an important risk factor for metabolic disease and various cancers. Treatments of obesity include lifestyle intervention, pharmacotherapy, and bariatric surgery. If weight loss with lifestyle intervention is only modest, pharmacotherapy might be needed. Pharmacotherapy agents can be grouped by treatment period as short term or long term use agent. Several sympathomimetic drugs such as benzphetamine, diethylpropion, phendimetrazine and phentermine, are approved for short term treatment due to their safety issues. For long term treatment, orlistat, lorcaserin, and combination of phentermine/topiramate are approved by U.S. Food and Drug Administration (FDA). Orlistat partially blocks intestinal digestion of fat, therefore producing weight loss. Lorcaserin is a serotonin 2C receptor agonist. The combination of phentermine/topiramate produces a mean weight loss of 8-10 kg. Side effects of each drug are quite different. For obesity patient, side effects are important factor when choosing drugs. The goal of this article is to review currently available anti-obesity drugs.

Antianginal effect of Trapidil was evaluated in 30 patients (18 male and 12 females) with angina rectoris. The results were follows : 1) Antianginal effect of the drug were good in 18 cases (60%) and fair in 8 cases (37%), and there was no effect in 4 cases(13%). 2) Improvement in ECG changes was observed in 29%. 3) There were no significant change in CBC, RUA, LFT, serum electrolyte and lipid study before and after medication. 4) The adverse effects of trapidil were constipation, gastric cramp and dizziness, respectively one case. But they were not required discontinuing the medicetion. On the basis of these results, Trapidol was evaluated to be promising antianginal drug.

The primary treatment goal of torticollis is to prevent the craniofacial deformities, limitation of neck movements and long-term postural changes. In order to offer precise guidelines for the treatment of torticollis regarding the cosmetic and functional results, we analyzed 99 torticollis children retrospectively for the ages at diagnosis and the start of treatment, the duration of treatment, the problems at first visitation, and the size of sternocleidomastoid mass. These patients visited the department of rehabilitation medicine, Holy Family Hospital from April 1991 to June 1997. The results showed that there was no relation between the number of problems at first visitation and the age at the start of treatment, but the group with 1 problem had a significantly shorter duration of treatment than the groups with more than 4 problems. The ages at diagnosis and at the start of treatment for the patients with a palpable neck mass were younger than those of the patients without a neck mass. The duration of treatment was longer for the patients with a larger size of mass by the ultrasonography of the neck. The ages at diagnosis and at the start of treatment, and the duration of treatment were all younger and shorter in the cosmetically satisfactory group than those of the cosmeticlly unsatisfactory group. However there was no significant difference between the functionally satisfactory group and unsatisfactory group in the ages at diagnosis and at the start of treatment, and the duration of treatment. In conclusion, when the treatment of torticollis was started early, especially at less than 3 months old, better cosmetic results were obtained, even though functional results were relatively satisfactory by the proper rehabilitation treatments. We want to emphasize that it is important to detect and treat the torticollis as early as possible for the better cosmetic results.

Background: The aim of this study was to examine various patient factors affecting first programmed embryo transfer (ET) outcomes under the freeze-all policy at a single tertiary university infertility center. Methods: This retrospective observational study reviewed the medical records of 243 couples who underwent their first ET using blastocysts collected under the freeze-all antagonist-controlled ovarian stimulation (COS) protocol from 2015 to 2023. Patients were grouped into pregnant and nonpregnant groups, and their data, including demographics, COS and ET outcomes, and embryo storage duration, were analyzed. Results: Patient body mass index, cause of infertility, follicle-to-oocyte index, distribution of blastocyst grades, number of transferred embryos, and embryo storage duration were not significantly different between the groups. In a simple comparative analysis, patients with successful clinical pregnancy tended to have significantly lower female and male age (33.83±3.67 and 35.32±4.54 years vs. 37.07±4.15 and 39.33±5.60 years, respectively), higher anti-Müllerian hormone levels (6.27±5.32 ng/mL vs. 4.14±3.82 ng/mL) and antral follicle counts (14.20±8.26 vs. 10.04±5.75), and higher numbers of retrieved oocytes and metaphase II oocytes (13.74±6.92 and 9.64±6.19 vs. 11.21±6.04 and 7.53±5.56, respectively). Multivariate logistic regression analysis of these variables revealed that only male age was a significant factor for successful clinical pregnancy (odds ratio, 4.768; 95% confidence interval, 1.252–18.162; p=0.022). Conclusion During the first programmed ET using blastocysts collected under the freeze-all antagonist COS protocol, male age and correspondingly the quality of gametes for fertilization were crucial for successful pregnancy, having more importance than calculated female ovarian reserve and embryo storage duration.
