, Jung-A Shin There is a growing trend of medical students using electronic devices for studying. This paper analyzes such trend and assesses if the utilization of devices is adequate to effectively help students to study.
Survey of total 155 medical students about the usage of the electronic devices for studying during the first year of medical school was done. The answers were matched with their exam scores in the first year.
Most of students were using a device, as a learning tool and the most important purpose of it was its convenience, especially for taking notes during lectures. However, students who didn't use a device when they learned anatomy or who studied with the printouts showed a tendency of receiving better scores on exams.
Utilizing electronic devices for studying tends to be more convenient, but not effective for studying anatomy.
, Su Jin Cho, Hae Soon Kim Pseudohypoaldosteronism (PHA) in infants is manifested by presence of hyperkalemia, hyponatremia, and metabolic acidosis. At initial stages, PAH is generally suspected as congenital adrenal hyperplasia. Transient PHA has been reported in infants with urinary tract infection and urinary tract malformation. We report a case of 5-month-old infant with failure to thrive and finally diagnosed with transient PHA due to urinary tract infection with vesicoureteral reflux.

, Angela Cho, Chul Min Park A 66-year-old postmenopausal woman received routine gynecologic check-up. Transvaginal ultrasonography and abdominal and pelvic computed tomography showed about 5-cm cystic mass in uterus with solid component and the patient had thin endometrium and the serum level of CA 125 was normal. We performed a total hysterectomy and bilateral salpingo-oophorectomy and found tumor which had brownish cystic fluid and about 2 cm sized and colored in light yellowish, polypoid protruding solid mass, located within the myometrial wall. Histopathological examination of frozen section revealed malignancy. The tumor was confined within the myometrium and its histologic type was clear cell adenocarcinoma. Finally we identified that the myometrial mass was clear cell adenocarcinoma originated from adenomyosis pathologically. The malignant transformation of adenomyosis is very rare. When we find a cystic change with solid component in adenomyosis patients, clear cell adenocarcinoma should be suspected as a differential diagnosis and magnetic resonance imaging should be considered for further evaluation.
