Nonsimultaneous Bilateral Internal Oblique Muscle Rupture in a Professional Baseball Batter: A Case Report / 대한스포츠의학회지

Abdominal oblique muscle injuries are relatively common in professional baseball players and can result in substantial loss of playing time. It is usually caused by a sudden movement of the torso in sports involving repetitive activity requiring trunk rotation and it tend to occur on the contralateral side of the dominant arm. We report a unique case of sequentially occurred bilateral abdominal internal oblique muscle rupture in a right-handed professional baseball batter over two seasons. Each internal oblique rupture had a different mechanism of the injury, the non-dominant side occurred during bat swing and the dominant side during bent leg sliding. After rest and rehabilitation, each injury was recovered to play in about 1 month.

Arteriovenous malformation in uterine cervix during pregnancy

As the development of Doppler ultrasonography, many cases of uterine arteriovenous malformation (AVM) have beed diagnosed. But there is no case of cervical AVM in pregnant uterus. We present a 33-year-old pregnant woman who was diagnosed with AVM of the uterine cervix during the midtrimester. Color Doppler sonography and magnetic resonance image were used for diagnosis. We performed Cesarean section because of the risk of massive bleeding from the cervical AVM at 34 weeks' gestation. This is the first case of cervical AVM during pregnancy with a successful outcome and an uneventful postpartum course.

Surgical impact on serum anti-Mullerian hormone in women with benign ovarian cyst: A prospective study

OBJECTIVE: The aim of this study was to evaluate the surgical impact of benign ovarian mass on ovarian reserve as measured by serum follicle stimulating hormone (FSH), estradiol (E2) and anti-Mullerian hormone (AMH) levels, antral follicle count (AFC) and ovarian volumes. In addition, the differences in ovarian reserve impairment between endometrioma cystectomy and non-endometrioma cystectomy were investigated. METHODS: In this prospective study, 22 patients of reproductive age (range, 18.35 years) with benign ovarian masses were enrolled to undergo laparoscopic cystectomy. Of whom 12 had endometriomas and 10 had non-endometriomas. On early follicular phase (day 3) of the cycle preceding the operation and three months after the laparoscopic cystectomy, serum levels of FSH, E2 and AMH, AFC and ovarian volumes were measured in all patients. Data were analyzed with Mann-Whitney U-test and Wilcoxon rank test using SPSS ver. 12.0 for statistic analysis. RESULTS: Median level of serum AMH was significantly decreased from 5.48 ng/mL (interquartile range [IQR], 2.80-7.47) before cystectomy to 2.56 ng/mL (IQR, 1.74-4.32) 3 months postoperation (P<0.05). On the other hand, no significant differences in FSH, E2, AFC and ovarian volumes were found between the preoperative and three months postoperative levels. In a subgroup analysis of the pathologic type of the ovarian cyst, postoperative serum AMH levels were significantly decreased in the endometrioma group, but not in the non-endometrioma group. CONCLUSION: Serum AMH levels were significantly decreased after laparoscopic cystectomy without any changes of other ovarian reserve tests.
