PURPOSE: The purpose of this study was to identify trends in intervention studies on childhood obesity in Korea. METHODS: From 1996, when the first research paper on childhood obesity intervention was published, to 2015, 192 published papers were analyzed using descriptive statistics. RESULTS: The number of studies increased sharply between 1996 and 2007, but declined slightly from then. The majority of studies involved only children as intervention participants. Most were elementary students, and overweight and obese children. Exercise therapy was the most common type of intervention. Parental participation was found in 35 studies, while teacher's participation was found in only one study. In many studies physiological indicators were used as measurement variables, but follow-up was done in only 10 studies. Finally, only a few studies applied a conceptual framework, while a quasi-experimental research design was used for most studies. CONCLUSION: Examination of trends in intervention studies on childhood obesity in Korea, shows there has been a quantitative increase but not enough improvement in terms of the quality of interventions. Findings in the present study suggest that it is necessary to seek diversity in terms of study participants, interventions and evaluation method along with quality improvement in research methodology.

PURPOSE: This study compared the effects of robotic single-port cholecystectomy (RC) and 3-port laparoscopic cholecystectomy (LC) on patients' surgical pain, postoperative complications, and satisfaction. METHODS: One hundred twenty patients with gallbladder disease scheduled for either LC or RC were recruited. Each patient was followed up for 1 week after hospital discharge. RESULTS: Time stayed in operating room was longer in patients with RC, however their hospital stay was shorter than those with LC (t = 3.01, P = 0.003). Since patients with RC received more analgesics during the surgery (t = 3.98, P < 0.001), all participants' surgical pain level were analyzed by using analysis of covariance. Patients who underwent RC reported less surgical pain consistently at 6 hours and first day after surgery and 2 days and 1 week later than patients in the LC. Repeated measure analysis of variance also demonstrated that the RC with single-port might cause less pain throughout the postoperative period (F = 25.68, P < 0.001). Participants' conditions appeared stable without complications such as infection or bleeding regardless of the surgical type however, overall satisfaction with RC showed significantly higher than those with LC except for one item, “the cost of surgery.” CONCLUSION: These results suggested that the RC might be a better choice for people who concern about surgical pain and early hospital discharge. Since there were no differences in postoperative health status between the 2 groups, health care providers as an advocate can provide more reliable information to their patients.

Breast hamartoma is a rare benign tumor that comprises lobular breast tissues with various admixtures of fibrous, fibrocystic, and adipose tissue. Hamartoma accounts for 0.7%-5.0% of all benign breast tumors. Myoid hamartoma is an extremely rare variant of mammary hamartoma characterized by the presence of smooth muscle component. Herein, we report a case of myoid hamartoma showing irregular margins and microcalcifications with a literature review.

A clinicopathologic study was per formed on 14 cases of malignant nondysgerminomatous ovari an germ cell tumors(NDOGCT) treated at the department of obstetrics and gynecology in Korea Cancer Center Hospital between Jan. l987 and,Jun. 1992. The results obtained were as follows ; 1. Median age of the patients was 27.5 years (range, 5 to 54) 2.Clinical symptoms presented were abdminal pain(64.3%), abdominal palpable mass(42.9%), abdominal distension(28.5%) in order of frequency. 3. Histopathologically, 7 cases(50%) were irnmature teratoma, 4 cases(28.6%) were endoder mal sinus tumor, 1 case(7.1%) was embryonal cell carcinoma, 2 cases(14.3%) were mixed germ cell tumor. 4. Bystage, 6 casse(42.9%) were in stage I, 1 case(7.1%) in stage Il, 2 cases(14.3%) in stage III, 3 cases(21.4%) in stage IV, and 2 cases(14.3%) in recurrence. 5, Serum alphafetoprotein was elevated in all patients withendodermal sinus tumor or embryonal carcinoma, and serum CA125 was elevated in about one half of the patients with nondysgerminomatous gerrn cell tumr. 6. l0 cases were managed by salpingo-oophorectomy with poatoperative chemotherapy, 3 cases by hysterectamy and salpingo-oophorectomy with postoperative chemotherapy. 7. Durations of follow up ranged 5 to 66 months, in that period, 5 cases were died, 4 cases were alive with disease and 4 casee wero no evidence of disease. 1 case was loat follow up after operation. All 5 patients were alive who had been treated with REP regirnen. In conelusion, prognosis of malignant NDOGCT is still poor in spite of adjuvant chemotherapy following surgery, and study ineluding appropriate chemotherapeutic regimen may be needed.

BACKGROUND AND OBJECTIVE: Mitral annulus velocity measured by doppler tissue imaging (DTI) has been used as a method of evaluation of the left ventricular diastolic function. This study was aimed to evaluate the left ventricular diastolic function using the mitral annulus velocity measured by DTI in the patients with hypertension. METHODS AND SUBJECTS: One hundered twenty nine patients with blood pressure above 140/90mmHg and age sex matched 123 normotensive subjects were studied. For measuring the mitral annulus velocities by DTI, we used the 2.5 MHz probe (Sequoia, Accuson) in apical four chamber view with the sample volume at the septal portion of the mitral annulus. RESULTS: Mitral annular velocities were easily obtained from all subjects. In the hypertension group, mitral annulus E'velocity was significantly lower than normotensive controls (5.4 1.3 cm/sec vs 6.5 1.8 cm/sec, p<0.001) and mitral annulus A' velocity was significantly higher than normotensive controls (8.6 1.4 cm/sec vs 7.9 1.1 cm/sec, p<0.001). In comparison with patients with normal LVML(IV mass index in hypertension group and subjects with normal LVMI in normotensive controls, mitral annulus E'velocity was reduced in patients with normal LVMI in hypertension group compared with subjects with normal LVMI in normotensive controls (5.6 1.4 cm/sec vs 6.7 1.8 cm/sec, p<0.001). CONCLUSION: Mitral annulus velocity measured by DTI could be used as one of the parameters in evaluating the early changes of left ventricular diastolic function in the patient with hypertension.

We experienced two cases of Boerhaave syndrome (spontaneous esophageal rupture). The first patient was a 62-year-old male who presented epigastric pain after several violent vomitings associated with alcohol ingestion. Diagnosis was done early and promptly in our emergency center and then definitive treatment was done only after 12hrs from onset of his symptom and he was discharged in relatively good condition 256ays after his admission. The second patient was a 44-year-old male who was transfered to our emergency center with chest pain, dyspnea and fever after vomitings associated with autobicycle accident. Diagnosis was delayed due to initial trauma oriented evaluation and incidious develpement of typical clinical findings and then he was managed conservatively but he died of multiple organ failure due to sepsis. We report these cases with literature review.

We performed a thermographic study to observe any possible interaction between the esophageal acid perfusion and the temperature changes of skin surface in patients with gastroesophageal reflux disease (GERD). Twenty-seven patients with GERD were categorized as group I(globus symptoms with posterior laryngitis) and group II (heartburn and/or regurgitation symptoms). Patients and 6 healthy volunteers underwent Bernstein test (BT) and digital infrared thermographic imaging (DITI) simultaneously. The positive rate for BT in group I and group II was 22.2% and 55.6%, respectively, and the DITI positive rate was 55.6% for group I and 50.0% for group II. None of healthy control were positive in BT or DITI. All subjects with DITI positive were hypothermic. The overall accordance rate between DITI and BT was 69.7%. All group I patients showed a diffuse type, while in group 11, 4 patients showed diffuse type and 5 patients showed localized type (p<0.05). In patients with DITI (+)/BT (-), 83.3% showed diffuse type, whereas equal numbers of diffuse and localized type were noted in patients with DITI (+)/BT (+). In conclusion, add contact with a sensitive mucosa leads to an activation of the sympathetic nervous system in some patients with GERD, inducing skin surface hypothermia.
