In the patient with extensive burn injury, the occult site of infection such as septic arthritis is easy to be overlooked because a painful hip joint may be confused for painful burn wounds around pelvic area. We describe a extensive burned young adult who experienced a septic hip joint with methicillin resistant Staphylococcus aureus bacteremia A 22 year old male who had full thickness burns of whole body (90%) presented with fever, groin pain, and immobility of right hip joint about 3 months after injury. The physical findings, radiographic findings and bone scan were diagnostic for a septic arthritis. Septic arthritis in the extensive burns may be misdiagnosed for painful burn wounds. Hematogenous septic hip arthritis by sustained bacteremia is rare, but clinical examination combined with appropriate laboratory and radiographic studies can lead to prompt diagnosis and treatment.

PURPOSE: The modified Hanley technique, which is used for treatment of a deep horseshoe fistula, has reduced damage to the external anal sphincter compared to the classic Hanley technique, but its shortcoming is that it causes inconvenience to the patient due to the fact that a drainage tube must be left in place for a long time. To solve this problem, the authors devised a self-pulsed washable seton and then compared the results of its use to determine its clinical usefulness. METHODS: The subjects of this study were 34 patients who were diagnosed with a deep posterior complex anal fistula and who were operated on by using the modified Hanley technique between January 1999 and December 2004. Twelve patients who were treated with the self-pulsed washable seton were classified as Group A, and 12 patients who were treated by using a conventional loose seton were placed in Group B. These two groups were compared for period of purulent discharge, period of leaving the seton alone, and recurrence rate. RESULTS: The period of purulent discharge was 18.75 days (15~24) for group Aand 29.75 days (24~37) for group B. The period of leaving the seton was 21.58 days (18~29) for group A and 32.58 days (28~39) for group B. The recurrence rate after surgery was 8.3% in group A and 16.7% in group B. CONCLUSIONS: The self-pulsed washable seton devised by the authors shortened the treatment period through more effective wound management, so we propose using it as a new method for treating a deep posterior horseshoe fistula.

Background: Videofluoroscopic swallowing study (VFSS) is currently considered the gold standard to precisely diagnose and quantitatively investigate dysphagia. However, VFSS interpretation is complex and requires consideration of several factors. Therefore, considering the expected impact on dysphagia management, this study aimed to apply deep learning to detect the presence of penetration or aspiration in VFSS of patients with dysphagia automatically. Methods: The VFSS data of 190 participants with dysphagia were collected. A total of 10 frame images from one swallowing process were selected (five high-peak images and five low-peak images) for the application of deep learning in a VFSS video of a patient with dysphagia. We applied a convolutional neural network (CNN) for deep learning using the Python programming language. For the classification of VFSS findings (normal swallowing, penetration, and aspiration), the classification was determined in both high-peak and lowpeak images. Thereafter, the two classifications determined through high-peak and low-peak images were integrated into a final classification. Results: The area under the curve (AUC) for the validation dataset of the VFSS image for the CNN model was 0.942 for normal findings, 0.878 for penetration, and 1.000 for aspiration. The macro average AUC was 0.940 and micro average AUC was 0.961. Conclusion This study demonstrated that deep learning algorithms, particularly the CNN, could be applied for detecting the presence of penetration and aspiration in VFSS of patients with dysphagia.

BACKGROUND: The study evaluated the clinical efficacy of a multi-parameter real-time polymerase chain reaction (PCR) test for patients with central venous catheter-related bloodstream infection (CRBSI). MATERIALS AND METHODS: Thirty five patients suspected to have CRBSI were enrolled. The SeptiFast(TM) (SF) multi-parameter real-time PCR test (Roche Diagnostics, Germany) and blood culture were performed and results were compared. RESULTS: The turn-around time for the SF test and blood culture was 32.6+/-28.9 hours and 115.8+/-23.5 hours, respectively. Among the 70 blood samples, the positive rates of SF test and blood culture were 34.3% and 27.1%, respectively, and the agreement rate was 62.9%. Gram-positive bacteria were detected in 10 patients with blood culture and 11 patients with SF test. Gram-negative bacteria were detected in one patient with a blood culture and in seven patients with SF test. Candida was not detected in blood culture but was detected in two patients by the SF test. CONCLUSIONS: SF test was faster and more sensitive for the detection of blood pathogens than blood culture. It provides a more sensitive detection of gram-negative and Candida in blood than does blood culture testing.

Purpose: Since accurate lung cancer segmentation is required to determine the functional volume of a tumor in [ 18 F]FDG PET/CT, we propose a two-stage U-Net architecture to enhance the performance of lung cancer segmentation using [ 18 F]FDG PET/CT. Methods: The whole-body [ 18 F]FDG PET/CT scan data of 887 patients with lung cancer were retrospectively used for network training and evaluation. The ground-truth tumor volume of interest was drawn using the LifeX software. The dataset was randomly partitioned into training, validation, and test sets. Among the 887 PET/CT and VOI datasets, 730 were used to train the proposed models, 81 were used as the validation set, and the remaining 76 were used to evaluate the model. In Stage 1, the global U-net receives 3D PET/CT volume as input and extracts the preliminary tumor area, generating a 3D binary volume as output. In Stage 2, the regional U-net receives eight consecutive PET/CT slices around the slice selected by the Global U-net in Stage 1 and generates a 2D binary image as the output. Results: The proposed two-stage U-Net architecture outperformed the conventional one-stage 3D U-Net in primary lung cancer segmentation. The two-stage U-Net model successfully predicted the detailed margin of the tumors, which was determined by manually drawing spherical VOIs and applying an adaptive threshold. Quantitative analysis using the Dice similarity coefficient confirmed the advantages of the two-stage U-Net. Conclusion The proposed method will be useful for reducing the time and effort required for accurate lung cancer segmentation in [ 18 F]FDG PET/CT.

Objective: The incidence of hip fractures is increasing worldwide with the aging population, causing a challenge to healthcare systems due to the associated morbidities and high risk of mortality. After hip fractures in frail geriatric patients, existing comorbidities worsen and new complications are prone to occur. Comprehensive rehabilitation is essential for promoting physical function recovery and minimizing complications, which can be achieved through a multidisciplinary approach. Recommendations are required to assist healthcare providers in making decisions on rehabilitation post-surgery. Clinical practice guidelines regarding rehabilitation (physical and occupational therapies) and management of comorbidities/complications in the postoperative phase of hip fractures have not been developed. This guideline aimed to provide evidence-based recommendations for various treatment items required for proper recovery after hip fracture surgeries. Methods Reflecting the complex perspectives associated with rehabilitation post-hip surgeries, 15 key questions (KQs) reflecting the complex perspectives associated with post-hip surgery rehabilitation were categorized into four areas: multidisciplinary, rehabilitation, community-care, and comorbidities/complications. Relevant literature from four databases (PubMed, EMBASE, Cochrane Library, and KoreaMed) was searched for articles published up to February 2020. The evidence level and recommended grade were determined according to the grade of recommendation assessment, development, and evaluation method. Results A multidisciplinary approach, progressive resistance exercises, and balance training are strongly recommended. Early ambulation, weigh-bearing exercises, activities of daily living training, community-level rehabilitation, management of comorbidities/complication prevention, and nutritional support were also suggested. This multidisciplinary approach reduced the total healthcare cost. Conclusion This guideline presents comprehensive recommendations for the rehabilitation of adult patients after hip fracture surgery.
