Purpose: This study aimed to compare the chest compression quality between compression-only cardiopulmonary resuscitation (CPR) and conventional CPR. Methods: This study involved 123 participants randomly assigned to either the chest compression-only CPR training and conventional CPR training. After training for 120 min, the participants performed CPR for 4 min and the CPR quality was evaluated. The primary outcome was evaluated as the mean compression depth, and the secondary outcome was calculated as the proportion of chest compressions with an appropriate depth among the total chest compressions. Results: The mean compression depth was more deeper in conventional CPR than in compression-only CPR (57mm vs. 53mm, p <.001). The proportion of appropriate chest compression depth was also more higher in conventional CPR (98.8% vs. 68.6%, p <.001). As compared with every minute over time for a total of 4 min, the mean compression depth and the proportion of appropriate chest compression depth were deeper and higher after 1 min in conventional CPR than in compression-only CPR. Conclusion: The results suggested that conventional CPR is a better method than compression-only CPR in terms of chest compression quality.

The success of image-guided breast biopsy depends on the biopsy method, needle selection, and appropriate technique based on the accurate judgment by the radiologist at biopsy. However, insufficient or inappropriate sampling of specimens may result in false-negative results or pathologic underestimation. Therefore, image-pathology concordance assessments after biopsy are essential for appropriate patient management. Particularly, the assessment of image-pathology concordance can avoid false-negative reports of breast cancer as a benign pathology. Therefore, this study aimed to discuss factors that impact the accurate interpretation of image-guided breast biopsy along with the appropriate assessments.

Supratentorial and infratentorial epidural hematoma (SIEDH) is a rare but life-threatening complication following traumatic brain injury. However, the literature on SIEDH is sparse, consisting only of a few small series. Prompt diagnosis and the application of appropriate surgical techniques are crucial for the rapid and safe management of SIEDH. Herein, we present three cases of SIEDH treated at our institution, employing a range of surgical approaches.

In general, the patients who transferred to the hospital by 119 rescue service at night go to the emergency room(ER) of general hospital rather than that of their nearby the 1st(clinic) and 2nd(local hospital) hospital. And the hospital is mainly selected not by 119 EMST but by patients or his/her conservators. Therefore we had studied retrospectively with emergency situation diary and medical chart for 697 patients of being transferred to one emergency medical center for 6 months since January 2004, and results are as follows. 1. The 280 patients(42.5%) of being transferred hospital at night by 119 rescue service were not emergency case and their average staying time in hospital was about $7.15{\pm}10.06$ minutes. 2. Transfer time was distributed in each time intervals of 1819, 2021, 2223, and 2401 and patients ratio in each intervals were 15.1%, 17.8%, 16.4%, and 15.2%. 3. In response of ambulance, the average time from the spot to the hospital was $14.53{\pm}9.27min$. and average distance of that was $7.95{\pm}9.21km$. 4. Diseases rather than traffic accidents or traumatic injury were main causes of ambulance calling and its value was 533(76.5%), and accidents were mainly occurred in patients' house and its value was 479(68.7%). 5. In time of transfer by 119 rescue service, hospital was mainly selected by patient/conservator and its value was 648(93.0%). In result. the hospital was selected not by EMST but by patient/conservator. 6. The case that the 1st grade EMT was rode in ambulance was 161(23.1%), and the case that 2nd EMT and emergency team member who educated for emergency were rode in ambulance were 504(72.3%). So the number of the 1st grade EMT was short in fire station of Kwangju metropolitan city than other city. 7. The first aids for patients before reaching hospital were limited to oxygen inhalation, airway control, and BLS for maintaining limbs and spine. So it seems to be a simple patients transfer. Consequently, to establish an efficient emergency medical system, it has been thought that it should be advanced a moderate education and public information about the appropriate use of emergency medical system toward citizen, and also need the hospital selection by the patients categorizing standards for 119 rescue service member, securing the 1st grade EMT, appropriate first-aids education, and securing professional human power in emergency room of the Ist(clinic) and 2nd(local hospital) hospital at night.

When treating firearms injuries, knowledge of the proper management is important because these injuries have high morbidity and mortality. However, due to strict gun safety regulations, surgeons in Asia often have limited experiences with gunshot wound management. Recently, the authors had the experience of removing a bullet that did not cause hemopneumothorax, but remained in the lung parenchyma. Due to the risk of complications that could occur if the bullet was not removed, surgical treatment was eventually performed to remove the bullet. A literature review was needed to determine whether this treatment was appropriate. We concluded that removing the bullet could prevent incidental complications. In this regard, the authors report a case along with a review of the relevant literature to suggest appropriate treatment directions for surgeons who do not have experience with gunshot wounds.

Traumatic flank hernia (TFH) is rare and prone to recurrence, which makes appropriate treatment challenging. No current guidelines define the optimal timing and method of repair. Meanwhile, recent advances in laparoscopic techniques are reshaping the options for the treatment of TFH. A dual approach that utilizes both laparoscopic and open methods has not previously been reported. Herein, we present the successful treatment of TFH after blunt trauma. A 46-year-old male patient underwent elective herniorrhaphy on hospital day 3, in which laparoscopic implantation of a sublay mesh and extracorporeal implantation of an onlay mesh were performed. Such techniques may be appropriate and result in feasible outcomes in hemodynamically stable patients with large TFH who are strongly suspected of having bowel herniation or concomitant intraperitoneal injuries. Larger studies are needed to assess the long-term results.

Galactosemia is an inborn error disorder of carbohydrate metabolism, caused by metabolic disturbances at various stages of the Leloir pathway. In patients with galactosemia, accurate diagnosis and appropriate care are essential to avoid complications and unnecessary treatments. And a careful differential diagnosis of the type of galactosemia is crucial. Even with an appropriate galactose-restricted diet, long-term complications may occur, especially in patients with classic galactosemia. So new treatment options are being developed. In this review, we will review the new symptoms of each subtype that have been reported recently and GALM (Galactose mutarotase) deficiency, a new form of galactosemia, and treatment policies according to recent guidelines.

Oral and maxillofacial infection is a common complication in patients undergoing chemotherapy. The treatment of oral diseases in such patients differs from that administered to healthy patients. This paper reports a case of acute osteomyelitis of odontogenic origin following a recent chemotherapy session. The patient's condition was life-threatening because of neutropenic fever and sepsis that developed during the inpatient supportive care. However, the patient showed prompt recovery within 40 days following the use of appropriate antibiotics and routine dressing, without the requirement for surgical treatment, except tooth extraction. As seen in this case, patients undergoing chemotherapy are more susceptible to rapid progression of infections in the oral and maxillofacial areas. Therefore, accurate diagnosis through prompt clinical and radiological examination, identification of the extent of infection, and assessment of the patient's immune system are crucial for favorable outcomes. It is also necessary to eliminate the source of infection through appropriate administration of antibiotics. In particular, a broad-spectrum antibiotic with anti-pneumococcal activity is essential. Proper antibiotic administration and wound dressing are essential for infection control. Furthermore, close consultation with a hemato-oncologist is necessary for effective infection management based on the professional evaluation of patients' immune mechanisms.

Group A streptococcus (GAS) rarely causes meningoencephalitis in children without risk factors. A previously healthy 8 year-old child presented with lethargy, high fever, and vomiting. The clinical course was unusual including intractable seizures, disseminated intravascular coagulation (DIC), and left hemiparesis in spite of the appropriate and timely administration of antibiotics and corticosteroids. The microbiologic studies revealed that the pathogen was susceptible to penicillin and GAS M18 strains. This case showed the importance of the GAS vaccine in addition to appropriate antibiotics.

Objective: To assess the appropriate follow-up interval, and rate and timepoint of cancer detection in women with Breast Imaging Reporting and Data System (BI-RADS) 3 lesions on screening ultrasonography (US) according to the type of institution. Materials and Methods: A total of 1451 asymptomatic women who had negative or benign findings on screening mammogram, BI-RADS 3 assessment on screening US, and at least 6 months of follow-up were included. The median follow-up interval was 30.8 months (range, 6.8-52.9 months). The cancer detection rate, cancer detection timepoint, risk factors, and clinicopathological characteristics were compared between the screening and tertiary centers. Nominal variables were compared using the chi-square or Fisher's exact test and continuous variables were compared using the independent t test or Mann-Whitney U test. Results: In 1451 women, 19 cancers (1.3%) were detected; two (0.1%) were diagnosed at 6 months and 17 (1.2%) were diagnosed after 12.3 months. The malignancy rates were both 1.3% in the screening (9 of 699) and tertiary (10 of 752) centers. In the screening center, all nine cancers were invasive cancers and diagnosed after 12.3 months. In the tertiary center, two were ductal carcinomas in situ and eight were invasive cancers. Two of the invasive cancers were diagnosed at 6 months and the remaining eight cancers newly developed after 13.1 months. Conclusion: One-year follow-up rather than 6-month follow-up may be suitable for BI-RADS 3 lesions on screening US found in screening centers. However, more caution is needed regarding similar findings in tertiary centers where 6-month follow-up may be more appropriate.
