OBJECTIVES: Visualization of the left atrial appendage(LAA) by the transesophageal echocardiography(TEE) is excellent, but it is difficult to visualize the LAA by the modified parasternal short-axis view(MPSA) in transthoracic echocardiography(TTE). We studied to determine the usefulness of the apical horizontal view(AHV) abtained by the apical rotation method of the transducer for the detection of the LAA. METHODS: We studied the MPSA and AHV in 602 patients, The LAA was observed during diastole of the LAA. We obtained an apical horizontal view by 45 degree clockwise rotation of the transducer from the apical 2 chamber view and compared with the visualization of the LAA in AHV and MPSA. RESULTS: Among 602 patients, LAA could not be visualized in 88(14.6%) because of a poor echo-window. LAA was more clearly visualized in 222 patients by the AHV than the MPSA and 56 patients by the MPSA than the AHV. LAA was same degree visualization in patients by the AHV and MPSA. In male and female, more than 55 ages and less than 55 ages, visualization of inner margin of the LAA by the AHV was more clear than by the MPSA. CONCLUSION: The AHV was a useful, noninvasive and reproducible method for the visualization of the LAA.

A 73-year-old man visited our hospital because of pain with swelling and redness on the right foot dorsum. He was diagnosed with liver cirrhosis and nodular hepatic cellular carcinoma. Lower extremity CT scan and MRI showed abscess formation in the right foot dorsum. Gram-negative cocci were recovered from the culture of drained pus at the site and identified as Neisseria skkuensis by 16S rRNA gene sequencing. Here, we report the first case of cellulitis due to N. skkuensis and provide a literature review.

PURPOSE: The aim of this study was to evaluate the stability of arginine-glycine-aspartic acid (RGD) peptide coatings on implants by measuring the amount of peptide remaining after installation. MATERIALS AND METHODS: Fluorescent isothiocyanate (FITC)-fixed RGD peptide was coated onto anodized titanium implants (width 4 mm, length 10 mm) using a physical adsorption method (P) or a chemical grafting method (C). Solid Rigid Polyurethane Foam (SRPF) was classified as either hard bone (H) or soft bone (S) according to its density. Two pieces of artificial bone were fixed in a customized jig, and coated implants were installed at the center of the boundary between two pieces of artificial bone. The test groups were classified as: P-H, P-S, C-H, or C-S. After each installation, implants were removed from the SRPF, and the residual amounts and rates of RGD peptide in implants were measured by fluorescence spectrometry. The Kruskal-Wallis test was used for the statistical analysis (alpha=0.05). RESULTS: Peptide-coating was identified by fluorescence microscopy and XPS. Total coating amount was higher for physical adsorption than chemical grafting. The residual rate of peptide was significantly larger in the P-S group than in the other three groups (P<.05). CONCLUSION: The result of this study suggests that coating doses depend on coating method. Residual amounts of RGD peptide were greater for the physical adsorption method than the chemical grafting method.

Pseudopolyposis occurs twice as often in ulcerative colitis as in Crohn's disease. Pseudopolypsis is divided into the followings: localized multiple pseudopolyposis, localized giant pseudopolyposis, generalized pseudopolyposis and long finger-like pseudopolyps. The most serious problem is confusion with carcinoma. Indications for operation are intussusception or obstruction, radiological simulation of carcinoma. The pseudopolyp could be managed by careful follow-up with colonoscopy and multiple biopsies. We report a case of localized giant pseudopolyposis of the cecum associated with Crohn's disease, with review of relevant literature.

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.
