A Case of Solitary Brain Metastasis from Uterine Mullerian Adenosarcoma with Sarcomatous Overgrowth

Uterine adenosarcoma (AS) are rare tumors and have more favorable outcomes than the aggressive uterine carcinosarcomas. Uterine adenosarcoma with sarcomatous overgrowth (ASSO) is a variant form of AS and exhibits aggressive growth of tumor and the prognosis is relatively poor compared with typical AS. Usually patterns of metastasis have been known to behave like endometrial carcinoma and spread through the lymphatics. Brain metastasis from uterine AS is extremely rare. Herein, we report a case of successfully surgically removed solitary brain metastasis without any extracranial recurrence from uterine ASSO after 4 years of primary treatment.

Untreated hyperthyroidism and high-dose thyroid hormone are associated with osteoporosis, and increased bone mineral density (BMD) has been demonstrated in postmenopausal females with hypoparathyroidism. Studies on the effect of suppressive levothyroxine (LT4) therapy on BMD and bone metabolism after total thyroidectomy in patients with differentiated thyroid carcinoma have presented conflicting results, and few studies in relation to the status of hypoparathyroidism have been studied. One hundred postmenopausal women and 24 premenopausal women on LT4 suppression therapy were included in this study. BMD of lumbar spine and femur and bone turnover markers were measured at the baseline and during the follow-up period up to 18 months using dual energy X-ray absorptiometry. Biochemical marker of bone resorption was measured by urine deoxypyridinoline and bone formation by serum osteocalcin. The age ranged from 36 to 64 years old. Thyroid stimulating hormone (TSH) was suppressed during the study. The results showed that BMD of femur and lumbar spine were not significantly changed in both pre- and postmenopausal women except femur neck in postmenopausal women without hypoparathyroidism. Patients with hypoparathyroidism had higher BMD gain than those without hypoparathyroidism in total hip (1.25 vs. -1.18%, P=0.015). Biochemical markers of bone turnover, serum osteocalcin, and urine deoxypyridinoline did not show significant change. In conclusion, patients with well differentiated thyroid carcinoma are not at a great risk of bone loss after LT4 suppressive therapy. The state of hypoparathyroidism is associated with increased BMD, particularly in postmenopausal women.
Helicobacter pylori 일차 표준 삼제요법: 양전자펌프억제제 복용방법에 따른 제균성적 비교

Background/Aims: Recent Korean studies performed over the past few decades have shown diminishing efficacy and unacceptability of clarithromycin-based triple therapy as first-line eradication therapy for Helicobacter pylori infection, based on evidence of a declining eradication rate. Triple therapy continues to be used as first-line eradication therapy despite concerns regarding high clarithromycin resistance among Koreans. Patient compliance and acid suppression are important factors associated with the H. pylori eradication rate. We investigated whether regular administration of a proton pump inhibitor (PPI) 30 minutes before a meal can improve the eradication rate. Materials and Methods: We retrospectively analyzed the data of 316 patients who were treated with first-line triple therapy (PPI, amoxicillin, and clarithromycin) for H. pylori infection between January 2012 and September 2017. Patients were divided into 2 groups based on the time of administration of the PPI (group A: before a meal, group B: after a meal). The urea breath test was performed 4∼6 weeks after eradication of infection. Results: Notably, 249 patients (78.8%, 249/316) showed successful eradication. The eradication rates in groups A and B were 87.5% (49/56 patients) and 76.9% (200/260 patients), respectively. We observed that regular administration of PPI before meals improved the eradication rate (P=0.079). Conclusions: We observed that although clarithromycin-based triple therapy was associated with an overall eradication rate <80%, regular PPI administration before meals improved the eradication rate. Regular PPI administration before meals and effective education to improve patient compliance could improve the eradication rate through maximal acid suppression.

Background/Aims: The quality of bowel preparation is one of the quality indicators for colonoscopy. The aim of this study was tocompare the efficacy of oral sulfate solution (OSS) and polyethylene glycol plus ascorbic acid (PEG-AA) for bowel preparation. Methods: The study involved 167 patients who underwent diagnostic colonoscopies. Inadequate bowel preparation was definedas any score of ≤1 in each colon section based on the Boston Bowel Preparation Scale. Multivariate logistic regression was used tocompare the efficacy of OSS and PEG-AA. Subgroup analyses were performed based on patient characteristics. Results: Overall, 106 (63.5%) patients received OSS, and 61 (36.5%) patients received PEG-AA. The rate of inadequate bowel preparation was 12.3% in patients receiving OSS and 32.8% in patients receiving PEG-AA (p=0.001). OSS (odds ratio [OR] = 0.26; p=0.003) and morning examination (OR=0.11; p=0.038) were significantly associated with efficient bowel preparation. The efficacyof OSS compared with PEG-AA was only significant in patients ≥50 years of age vs. <50 years of age (OR=0.13; p=0.001 vs. OR=0.96; p=0.959) and female vs. male patients (OR=0.06; p=0.002 vs. OR=0.58; p=0.339). Conclusions: OSS was significantly more efficient for bowel preparation than PEG-AA, especially in patients ≥50 years of age and female patients. Morning examination led to a good quality of bowel preparation, irrespective of the preparation regimen.
