This study aims to identify the clinical characteristics for diagnosing streptococcal pharyngitis. The correlation between eighteen clinical manifestations and rapid antigen detection test results was analyzed. Among 205 patients, five clinical manifestations, pharyngeal hemorrhage (odds ratio [OR] = 11.85), palatal hemorrhage (OR = 9.32), tonsillar swelling (OR = 4.37), rash (OR = 3.02), and enlarged cervical nodes (OR = 1.91), were significantly correlated with group A Streptococcus (GAS) pharyngitis. Traditional indicators such as fever, pharyngeal redness, acute onset, headache, rhinorrhea, cough, tonsillar exudate, and cervical tenderness were not statistically related to GAS pharyngitis. Therefore, physicians should be cautious in using these traditional indicators

This study was to find out whether the rendering screen difference affect to measuring distance in a CAD program according to three types of CAD programs. Materials and methods: The model presented in ISO 12836 for dental scanner evaluation was reduced by 70%. This model was repeatedly scanned 15times using Trios II (3Shape, Denmark). Using the output STL file, 3Shape CAD, inLab 15, and ExoCAD programs were used to measure the horizontal distance (H) and vertical distance (V) between adjacent point angle, and for each experiment, three groups were set according to the CAD program type. Statistical analysis was performed using One-way ANOVA test and post hoc was performed using Dunnett T3 test. Results: In the horizontal and vertical distance measurement, there was no difference in the average of the measured values between the three groups according to the CAD program (P>.05). Conclusion: There were no effect of the difference in the rendering screen in the horizontal and vertical linear distance measurements of the inlay model on the dental CAD program.

Background: Pharyngitis is one of the most common conditions encountered in primary health care facilities. Accurate differentiation of group A streptococcus (GAS) infection from viral infection is difficult. The STANDARD F Strep A Ag FIA (SD BIOSENSOR, Korea) is a rapid antigen detection test (RADT) that has been recently developed for diagnosing GAS pharyngitis. In this study, we evaluated the diagnostic performance of the STANDARD F Strep A Ag FIA and compared the results between the RADT and conventional throat culture. Methods: Throat swab samples were obtained from a total of 372 children presenting pharyngitis symptoms in five pediatric clinics in Changwon, Korea from July 2018 to October 2019. A comparative study between STANDARD F Strep A Ag FIA and Sofia Strep A FIA (Quidel, USA) was performed. Two throat swabs were taken simultaneously from each patient for RADT. The third throat swab was stored in a transport tube containing Stuart's transport medium for culture. Performance and kappa index of STANDARD F Strep A Ag FIA were evaluated. Results: GAS infection was detected in 29.3% (109/372) patients, using the STANDARD F Strep A Ag FIA. The sensitivity, specificity, positive predictive value, and negative predictive value were 95.0%, 95.2%, 88.1%, and 98.1%, respectively. The STANDARD F Strep A Ag FIA showed an excellent concordance rate of 96.5% and a kappa value of 0.89 compared to Sofia Strep A FIA. Conclusion The STANDARD F Strep A Ag FIA demonstrated an excellent performance along with Sofia Strep A FIA for the diagnosis of GAS pharyngitis.

PURPOSE: To determine the clinical efficacy of percutaneous vertebroplasty in cases of painful and medically intractable osteoporotic vertebral compression fracture. MATERIALS AND METHODS: Ninety-eight patients (20 men and 78 women; mean age, 69 years) underwent 122 per-cutaneous vertebroplasty procedures for the treatment of osteoporotic vertical compression fracture. For the evaluation of bone mass, bone densitometry was performed in 45 patients, and to assess the recent evolution of the fracture, all 98 underwent MRI. Percutaneous vertebroplasty involves percutaneous transpedicular puncture of the involved vertebrae followed by the injection of a Polymethylmethacrylate(PMMA)-Barium mixture into the vertebral body. To assess leakage of the mixture into the epidural tissue, neural foramina, venous plexus and paravertebral tissue, we then immediately obtained a computerized tomographic (CT) scan, assessing the clinical efficacy of the procedure on the basis of time required for pain relief (defined as more than 60% reduction of initial pain), and time required for ambulation without significant pain. RESULTS: Percutaneous vertebroplasty was successful in all patients. Pain relief was accomplished within 1-5(mean, 1.8) days and early ambulation without significant pain was possible within 2 -15 (mean, 3.3) days. Post-procedural CT scanning revealed leakage of the PMMA-barium mixture into Paravertebral tissue(n=41), the paravertebral venous plexus (n=34) and epidural tissue (n=4). No neural foraminal leakage was identified, and no procedure-related complication requiring surgical treatment occurred. CONCLUSION: Percutaneous vertebroplasty is an effective new interventional procedure for the treatment of osteoporotic vertebral compression fracture. It relieves pain, provides early mobilization, and strengthens involved vertebral bodies.

OBJECTIVE: The authors report a result of application of cervical hollow cage(RABEA(TM)) without bone graft to the patients of one-level cervical spondylosis or acute cervical disc herniation to fill and stabilize a vacant space following anterior decompression. METHODS: Twenty-one patients from May 1999 to April 2001 had been taken procedure with cervical hollow cage system following anterior decompression and there had been no additional bone graft or screw fixation or fusion. Pain relief and clinical outcome were evaluated, and the intervertebral disc height and segmental angle for radiological assessment were examined. All patient were followed up for 12 months at least. RESULTS: The result was excellent in 14 cases(66.7%), good in 6 cases(28.6%) and poor in 1 case(4.8%). In the lateral projection, the mean of preoperative disc height and segmental angle were significantly improved after surgery and maintained during follow-up periods. No abnormal displacement were recorded at dynamic flexion and extension lateral X-ray and no cage rotation or retropulsion was noted in follow-up periods. Three patients(14.3%) was observed to subside of disc height on the postoperative periods and only one of their patients was dissatisfied with surgery. CONCLUSION: Cervical hollow cage is simple to perform and reduces the operation time. Besides clinical improvement, it improves mechanical stability and radiological profile as the physiologic level. The cervical hollow cage might be an alternative to traditional cervical interbody fusion with bone graft.

Chlorfenapyr is widely used as an insecticide, despite it being fatal to humans. However, chlorfenapyr- induced central nervous system toxicity has rarely been reported. We report the magnetic resonance imaging (MRI) findings in a rare case of chlorfenapyr-induced toxic leukoencephalopathy. A 71-year-old man who had ingested chlorfenapyr approximately two weeks prior visited our hospital and presented with bilateral lower motor weakness and voiding dysfunction that had developed two days before admission. Brain MRI revealed extensive bilateral white matter abnormalities involving the corpus callosum, internal capsule, brain stem, and bilateral middle cerebellar peduncle. Furthermore, spine MRI revealed diffuse swelling and hyperintensity on the T2-weighted images.
