A retrospective clinical study on 63 cases of intussusception in infants and children, who were admitted to the department of pediatrics and surgery from May, 1974 to Feb. 1978, was done. The prognosis of this disease is dependent upon early diagnosis and treatment but the causatio of this disease is not clear yet. It is a relatively common disease and we think it is worthwhile to analyze our won cases. The results were : 1. Among 63 cases, 37 were admitted to the department of pediatrics and 36 were admitted to the department of GS. 2. In age distribution, 85% of the patients were under 1 year of age and the peak incidence was 3~9 months of age. 3. Male was predominant than female. Male to female ratio was 2.8:1 4. The 58.8% of the patients were above 50 percentile of body weight comparing with Korean standard data. 5. In the aspect of the etiology, 96.9% of the cases were idiopathic and only 3.1% of the cases had organic causes. 6. The 4 cardinal symptoms were abdominal pain(93.7%), vomiting(90.%), bloodymucous stool(80.1%) and abdominal mass(74.6%) 7. Among the cases, colocolic type was 33.3%, ileocolic type was 22.2% and ileocecal type was 20.6% 8. The 71.4% of the cases were reduced successfully by barium enema. 9. Recurrence rate was 4.8%.

One-step apexification using mineral trioxide aggregate (MTA) has been reported as an alternative treatment modality with more benefits than the use of long-term calcium hydroxide for teeth with open apex. However, orthograde placement of MTA is a challenging procedure in terms of length control. This case series describes the sequence of events following apical extrusion of MTA into the periapical area during a one-step apexification procedure for maxillary central incisor with an infected immature apex. Detailed long-term observation revealed complete resolution of the periapical radiolucent lesion around the extruded MTA. These cases revealed that direct contact with MTA had no negative effects on healing of the periapical tissues. However, intentional MTA overfilling into the periapical lesion is not to be recommended.

Background: We investigated whether Lactobacillus plantarum strain LMT1-48, isolated from Korean fermented foods and newborn feces, is a suitable probiotic supplement to treat overweight subjects. Methods: In this randomized, double-blind, placebo-controlled clinical trial, 100 volunteers with a body mass index of 25 to 30 kg/m2 were assigned randomly (1:1) to receive 2×1010 colony forming units of LMT1-48 or to a placebo treatment group. Body composition was measured by dual-energy X-ray absorptiometry, and abdominal visceral fat area (VFA) and subcutaneous fat area were measured by computed tomography scanning. Changes in body fat, VFA, anthropometric parameters, and biomarkers were compared between the two treatment groups (ClinicalTrials.gov number: NCT03759743). Results: After 12 weeks of treatment, the body weight decreased significantly from 76.6±9.4 to 75.7±9.2 kg in the LMT1-48 group but did not change in the placebo group (P=0.022 between groups). A similar pattern was found in abdominal VFA between the two groups (P=0.041). Serum insulin levels, the corresponding homeostasis model assessment of insulin resistance, and leptin levels decreased in the LMT1-48 group but increased in the placebo group (all P<0.05). Decrease in body weight and body mass index by treatment with LMT1-48 was correlated with increase in Lactobacillus levels significantly. LMT1-48 also increased Oscillibacter levels significantly, which were negatively correlated with triglyceride and alanine transaminase levels. Conclusion Administration of LMT1-48 decreased body weight, abdominal VFA, insulin resistance, and leptin levels in these subjects with overweight, suggesting its anti-obesogenic therapeutic potential.

Background: Understanding the age-related morphological changes of facial soft tissue is fundamental in achieving improved outcomes of rejuvenating procedures. Three-dimensional (3D) photogrammetry is a reliable and convenient anthropometric tool to assess facial soft tissue. Objective: The aim of this study was to establish age-related facial soft tissue morphology in Korean adult females using non-invasive 3D photogrammetry. Methods: One hundred and ninety-two female participants were divided into three groups based on age: the younger group (aged 20∼39 years), middle group (40∼59 years), and older group (60∼79 years). Thirty-six landmarks were identified via 3D photogrammetric scanning (Morpheus 3D, Morpheus Co., Ltd., Seongnam, Korea). Fortyone facial dimensions were analyzed using the imaging software to find significance between the age groups. Results: Smaller upper-facial volume (p=0.019) and shorter upperfacial height (p=0.034) were observed in the older group than in the younger group. In the mid-face, narrowed palpebral fissure (p＜0.001) with elongated upper eyelid height (p＜0.001) and widened nose (p＜0.001) were observed in the older group compared with the younger group. Longer lower-facial height (p＜0.001) with longer and wider philtrum (p＜0.001, p=0.004, respectively), shorter lower vermilion height (p＜0.001), wider mouth width (p＜0.001), and smaller lower vermilion angle (p＜0.001) were seen in the older group when compared with the younger group. Moreover, greater angles of nasofrontal, nasomental, and labiomental angle (p=0.015, p=0.015, p=0.080, respectively), and smaller nasofacial angle (p=0.034) were observed in the older group than in the younger group. Conclusion Our results provide clues of aging-related facial morphological characteristics in Korean female population.

Purpose: To investigate the efficacy and safety of a newly developed thermo-responsive sol-gel, ABT13107, for reducing the formation of intrauterine adhesions (IUAs) after hysteroscopic surgery. Materials and Methods: In this multicenter, prospective, randomized trial (Canadian Task Force classification I), 192 women scheduled to undergo a hysteroscopic surgery at one of the eight university hospitals in South Korea were randomized into the ABT13107 group or the comparator (Hyalobarrier ® ) group in a 1:1 ratio. During hysteroscopic surgery, ABT13107 or Hyalobarrier® was injected to sufficiently cover the entire intrauterine cavity. Results: The patients returned to their respective sites for safety assessments at postoperative weeks 1 and 4 and for efficacy assessments at postoperative week 4. The post-surgery incidence of IUAs was 23.4% in the ABT13107 group and 25.8% in the comparator group; this difference met the criteria for ABT13107 to be considered as not inferior to the comparator. No differences were found in the extent of adhesions, types of adhesions, or the cumulative American Fertility Society score between the two treatment groups. Most adverse events were mild in severity, and no serious adverse events occurred. Conclusion ABT13107, a new anti-adhesive barrier containing hyaluronic acid, was not inferior to the highly viscous hyaluronic acid anti-adhesive barrier, Hyalurobarrier® in IUA formation after hysteroscopic surgery (Clinical trial registration No. NCT 04007211).

Members of prostaglandin (PG) E-series elicit cellular effects mainly through adenylyl cyclase-cAMP signaling. The role of PGE2-induced increase in cAMP has been shown to be compartmentalized in the cardiac myocytes: PGE2-induced increase of cAMP is not involved in the control of cardiomyocytic contraction. The purpose of the present study was to define the effect of PGE1 on the cGMP levels and the role of PGE1 in the atrial secretory function. Experiments were performed in perfused beating rabbit atria and atrial contractile responses, cGMP and cAMP efflux, and atrial natriuretic peptide (ANP) secretion were measured. PGE1 increased cGMP as well as cAMP efflux concentration in a concentration-dependent manner, however, no significant changes in atrial secretory responses were observed (with 1.0microM PGE1; for cGMP, 144.76+/-37.5%, n=11 versus -16.81+/-4.76%, n=6, control, p<0.01; for cAMP, 187.60+/-41.52%, n=11 versus 7.38+/-19.44%, n=6, control, p<0.01). PGE1 decreased atrial dynamics slightly but transiently, whereas PGE2 showed similar effects but with lower potency. Isoproterenol increased atrial cAMP efflux (with 2.0 nM; 145.71+/-41.89, n=5 versus 7.38+/-19.44%, n=6, control, p<0.05) and mechanical dynamics and decreased ANP secretion. The PGE1-induced increase in cGMP efflux showed a bell-shaped concentration-response curve. PGE1-induced increase of cGMP efflux was not observed in the presence of L-NAME, an inhibitor of nitric oxide (NO) synthase, or ODQ, an inhibitor of NO-sensitive guanylyl cyclase. L-NAME and ODQ showed no significant effect on the PGE1-induced transient decrease of atrial dynamics. These data indicate that PGE1 increases cGMP levels via NO-soluble GC signaling in the cardiac atrium and also show that PGE1-induced increases in cGMP and cAMP levels are not involved in the regulation of atrial secretory and contractile functions.

PURPOSE: To evaluate the response rate and toxicity of combination chemotherapy including 5-fluorouracil (F), leucovorin (L), ifosfamide (I) and cisplatin (P) for the previously untreated patients with unresectable stage IIIB or IV non-small cell lung cancer. MATERIALS AND METHOD: The doses of FLIP were 5-fluorouracil 800 mg/m2 CI days 1-5, leucovorin 20 mg/m2 IV days 1-5, ifosfamide 1000 mg/m2 CI days 1-3, cisplatin 100 mg/m2 IV day 1 respectively. Cycles were repeated every 3 weeks until disease progression. Seventy-three previously untreated patients were enrolled. Age ranged from 30 to 73 (median 56 years); 43 were male, 30 female. Fifty-three patients had performance status (ECOG) 0-1 and 19 performance status 2. Twenty-two patients had stage IIIB and 51 stage IV. Follow-up ranged from 7+ to 160weeks (median 57 weeks). RESULTS: The overall response rate was 46.7% for 62 evaluable patients. (CR 1 patient, PR 28 patients) Median response duration was 24 weeks (range 1+ to 36+ weeks). Toxicity > Grade II (WHO) included: granulocytopenia 19.8%, anemia 13.5%, nausea and vomiting 31.5% stomatitis 46.5%, neuropathy 24.6%. CONCLUSION: FLIP chemotherapy was comparable to other combination chemotherapy for advanced non-small cell lung cancer with moderate toxicities.
