From January 1988 to December 1991, 39 fractures of the lateral condyle of humerus in children were treated at the Department of Orthopaedic Surgery, Sung-Ac General Hospital. It was possible to follow up from one year to four years and eleven months. The authors have analyzed the method of treatment on the basis of the degree of displacement in the change of Carrying angle and Baumann's angle. The results were as follows; 1. Of the 39 cases, the age incidence was confined to 2 to 12 years of age and the average age of the patients were 5 years. 2. Most fractures were Milch type II (29 cases) in contrast to Milch type I (10 cases). 3. According to the initial displacement of the fracture, 8 cases were Jokob's stage I, 21 cases of stage II & 10 cases of stage III. 4. There were no significant difference in the range of change of Carrying angle and Baumann's angle according to initial displacement of fracture site. However, significant difference in outcome were noticed from open reduction and internal fixation in comparison to closed reduction and percutaneous pinning. 5. In all 39 cases, lateral condylar overgrowth (10 cases), cubitus varus (1 cases) and cubitus valgus (3 cases) were noticed as complications but clinical significance was not noted. 6. The above results suggest that internal fixation is recommended for firm fixation although displacement is not severe. In case of Jakob's stage III, anatomical reduction is required in order to reduce additional damage on articular surface and epiphyseal plate caused by excessive manipulation.

Pneumoperitoneum usually indicates rupture of a hollow viscus and considered a surgical emergency. But air may also enter the peritoneum from the lung or the genital organs in female without visceral perforation. While scuba diving, the rapid ascent is usually controlled by placing in a decompression chamber and the excess gas volume is exhaled. Failure to allow this excess gas to escape will result in overdistension of air passage, which may rupture resulting in pulmonary interstitial emphysema or, if air enters the circulation, air embolus can occur. Pneumo-peritoneum is a rare complication of diving accidents. While the majority of cases are not related to an intraabdominal catastrophy, more than 20% have been the result of gastric rupture. We report a 42-yr-old male patient with massive pneumoperitoneum after scuba diving, who presented himself with dyspnea and abdominal distension. Knowledge of this rare condition and its benign course may allow the emergency physician and surgeon to order appropriate studies to help avoid unnecessary surgical treatment. It is important to determine promptly whether the air emanated from a ruptured viscus or was introduced from an extraperitoneal source. Free air in the abdomen does not always indicate a ruptured intra-abdominal viscus.

PURPOSE: The purpose of this study is to determine the usefulness of locally harvested autobone as a filling material for fusion. MATERIALS AND METHODS: Retrospective study was conducted for 21 patients diagnosed as cervical disc herniation with cervical myelopathy or radiculopathy who underwent anterior cervical fusion using locally harvested autobone and polyetheretherketone solis cage from June 2006 to September 2009, with a follow-up period of longer than 5 years. Radiologic outcomes were evaluated by the rate of bone union, the change of intervertebral height, and the subsidence of the cage. RESULTS: In clinical results, visual analogue scale score was 5.8±0.71/7.7±0.78 at preoperative, 1.6±0.58/2.3±0.97 at 1-year follow-up, 1.8±0.81/2.7±1.28 at 5-year follow-up, and neck disability index score was 34.3±6.2 in preoperative stage, 6.25±3.21 at 1-year follow-up, and 6.51±4.05 at 5-year follow-up. Radiologically intervertebral height was reduced from average 6.31±0.93 mm in 1-year follow-up to average 6.22±0.85 mm in 5-year follow-up. Subsidence of cage was average 1.28±0.41 mm at 1-year follow-up and average 1.31±0.43 mm at 5-year follow-up, with no statistically significant difference (p>0.05). Average subsidence of cage in these cases was 3.25 mm. In postoperative complication, screw breakage occurred in 1 case, screw pull out occurred in 1 case, and there was no postoperative infection. CONCLUSION: Using locally harvested autobone as filling material for fusion resulted in outstanding bone union and improvement of clinical results. In long term follow-up, there was no significant difference in union rate and complication incidence. Therefore use of locally harvested autobone as a filling material for fusion is considered an effective method.

Background/Aims: Minimising total ischemic time (TIT) is important for improving clinical outcomes in patients with ST-segment elevation myocardial infarction who have undergone percutaneous coronary intervention (PCI). TIT has not shown a significant improvement due to persistent pre-hospital delay. This study aimed to investigate the risk factors associated with pre-hospital delay. Methods: Individuals enrolled in the Korea Acute Myocardial Infarction Registry-National Institutes of Health between 2011 and 2015 were included in this study. The study population was analyzed according to the symptom-to-door time (STDT; within 60 or > 60 minutes), and according to the type of hospital visit (emergency medical services [EMS], non-PCI center, or PCI center). Results: A total of 4,874 patients were included in the analysis, of whom 28.4% arrived at the hospital within 60 minutes of symptom-onset. Old age (> 65 years), female gender, and renewed ischemia were independent predictors of delayed STDT. Utilising EMS was the only factor shown to reduce STDT within 60 minutes, even when cardiogenic shock was evident. The overall frequency of EMS utilisation was low (21.7%). Female gender was associated with not utilising EMS, whereas cardiogenic shock, previous myocardial infarction, familial history of ischemic heart disease, and off-hour visits were associated with utilising EMS. Conclusions Factors associated with delayed STDT and not utilising EMS could be targets for preventive intervention to improve STDT and TIT.

Background and Objectives: Accumulating evidence shows that sodium-glucose cotransporter 2 inhibitors (SGLT2is) reduce adverse cardiovascular outcomes. However, whether SGLT2i, compared with other antidiabetic drugs, reduce the new development of atrial fibrillation (AF) is unclear. In this study, we compared SGLT2i with dipeptidyl peptidase-4 inhibitors (DPP-4is) in terms of reduction in the risk of AF in individuals with type 2 diabetes. Methods: We included 42,786 propensity score-matched pairs of SGLT2i and DPP-4i users without previous AF diagnosis using the Korean National Health Insurance Service database between May 1, 2016, and December 31, 2018. Results: During a median follow-up of 1.3 years, SGLT2i users had a lower incidence of AF than DPP-4i users (1.95 vs. 2.65 per 1,000 person-years; hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.55–0.97; p=0.028]). In individuals without heart failure, SGLT2i users was associated with a decreased risk of AF incidence (HR, 0.70; 95% CI, 0.52–0.94; p=0.019) compared to DPP-4i users. However, individuals with heart failure, SGLT2i users was not significantly associated with a change in risk (HR, 1.04; 95% CI, 0.44–2.44; p=0.936). Conclusions In this nationwide cohort study of individuals with type 2 diabetes, treatment with SGLT2i was associated with a lower risk of AF compared with treatment with DPP-4i.

Background/Aims: While switching strategies of P2Y12 receptor inhibitors (RIs) have sometimes been used in acute myocardial infarction (AMI) patients, the current status of in-hospital P2Y12RI switching remains unknown. Methods: Overall, 8,476 AMI patients who underwent successful revascularization from Korea Acute Myocardial Infarction Registry-National Institute of Health (KAMIR-NIH) were divided according to in-hospital P2Y12RI strategies, and net adverse cardiovascular events (NACEs), defined as a composite of cardiac death, non-fatal myocardial infarction (MI), stroke, or thrombolysis in myocardial infarction (TIMI) major bleeding during hospitalization were compared. Results: Patients with in-hospital P2Y12RI switching accounted for 16.5%, of which 867 patients were switched from clopidogrel to potent P2Y12RI (C-P) and 532 patients from potent P2Y12RI to clopidogrel (P-C). There were no differences in NACEs among the unchanged clopidogrel, the unchanged potent P2Y12RIs, and the P2Y12RI switching groups. However, compared to the unchanged clopidogrel group, the C-P group had a higher incidence of non-fatal MI, and the P-C group had a higher incidence of TIMI major bleeding. In clinical events of in-hospital P2Y12RI switching, 90.9% of non-fatal MI occurred during pre-switching clopidogrel administration, 60.7% of TIMI major bleeding was related to pre-switching P2Y12RIs, and 71.4% of TIMI major bleeding was related to potent P2Y12RIs. Only 21.6% of the P2Y12RI switching group switched to P2Y12RIs after a loading dose (LD); however, there were no differences in clinical events between patients with and without LD. Conclusions In-hospital P2Y12RI switching occurred occasionally, but had relatively similar clinical outcomes compared to unchanged P2Y12RIs in Korean AMI patients. Non-fatal MI and bleeding appeared to be mainly related to pre-switching P2Y12RIs.
