The chest radiographs and angiograms were retrospectively evaluated in 47 patients with pulmonary atresia (PA) and ventricular septal defect (VSD) to determine the characteristic findings of major aortopulmonary collateral arteries (MAPCSs) on the chest radiographs. Of 47 patients, 23 had MAPCAs and 24 had only PDA for blood supply of whole right and left lung. Chest radiographs enabled identification of 16 of 23 patients with MAPCAs. The most common finding of MAPCAs was inappropriately large peripheral pulmonary vasculature (n=16, 69.6%). The other findings were tortuosity of pulmonary vasculature (n=12, 52.2%), focal unevendistribution of pulmonary vasculature (n=12, 52.2%), and two descending pulmonary arteries (n=4, 17.4%). When chest radiographs showed two or more findings of MAPCAs, MAPCAs could be differentiated from PDA with statistical significance (p<0.005). It is concluded that chest radiographs may help to identify MAPCAs before angiography if two-dimensional echo ardiography suggests PA with VSD.

Purpose:
This study sought to evaluate the clinical effectiveness of the shortening effect of the modified Weil osteotomy for the treatment of Freiberg’s disease.
Materials and Methods:
We reviewed 21 cases treated with the modified Weil osteotomy for Freiberg’s disease from November 2005 to June 2019. The average follow-up period was 32.5 months and the mean age of the patients was 38.3 years. The clinical results were analyzed using the American Orthopaedic Foot and Ankle Society (AOFAS) lesser metatarsophalangeal-interphalangeal scale, the visual analogue scale (VAS), and the range of motion (ROM) of the metatarsophalangeal joint. In the radiologic evaluation, the length of preoperative and postoperative metatarsal shortening was compared.
Results:
The average AOFAS lesser metatarsophalangeal-interphalangeal scale showed an improvement from 60.5 preoperatively to 90.9 at the latest follow-up. VAS showed a decrease from 5.4 preoperatively to 0.9 at the latest follow-up. ROM of the affected metatarsophalangeal joint increased from 40.2 degrees preoperatively to 58.6 degrees at the latest follow-up. The mean length of metatarsal shortening was 6.7 mm. There was no transfer metatarsalgia, osteonecrosis, and definite joint space narrowing.
Conclusion
Modified Weil osteotomy with second layer cutting is an effective treatment option to restore the joint surface and painless joint motion for patients with Freiberg’s disease.

Fourty three patients with tuberculous spondylitis were surgically treated through the anterior approach at our hospital from January, 1989 to December, 1994. Among them, 32 cases were followed up more than 18 months postoperatively, and were included in this study. The most prevalent location was lumbar region(50%). Paraparesis was frequently seen in patients with middle and lower thoracic spinal lesions and all patients with neurologic deficits improved after decompression of spinal cord. Autogenous rib and/or iliac strut bone grafting was performed, followed by spinal instrumentation. Solid bone fusion was obtained in all patients. There was no need for prolongation of duration of antituberculous drug therapy and no increased incidence of secondary infection due to spinal instrumentation.

Gel bleeding following breast augmentation using silicone breast implants (SBIs) occurs when microscopic silicone droplets diffuse through the implant surface, potentially resulting in complications such as capsular contracture and immune responses related to breast implant illness. Prompt and reliable diagnostic measures are crucial, as the presentation of gel bleeding can resemble cancer, making an accurate diagnosis challenging. This report discusses a rare case of axillary silicone lymphadenopathy caused by gel bleeding in a 48-year-old woman with intact SBIs. Silicone lymphadenopathy can be suspected based on mammography, ultrasonography, and magnetic resonance imaging in patients with a history of SBI insertion, and confirmation can be obtained through a pathological examination. Excisional biopsy is generally recommended for symptomatic patients, while treatment may not be necessary for asymptomatic patients; However, removal can be considered if the patient indicates a preference for it. Patients with silicone lymphadenopathy require replacement of SBIs to examine the breast capsule and verify the integrity of the implant. This case highlights the importance of considering gel bleeding as a potential cause of silicone lymphadenopathy, even in patients with intact SBIs.

Cases showing memory disturbances with isolated retrograde memory without any definitive brain lesions are classified as dissociative amnesia. Improvements in imaging techniques have allowed the organic causes of this disease to be identified in several recent cases. Several studies have diagnosed cases of memory disorders as pure retrograde amnesia (PRA). The patient reported here had no psychiatric disorder and had normal MRI results, but showed hypometabolism in PET that met the criteria for PRA.

BACKGROUND: Aspirin resistance (AR) in platelet function assays showed substantial variation depending on the methods used to evaluate it. METHODS: In this study, we prospectively compared the results of Multiplate impedance platelet aggregometry (IPA) with those of light transmission aggregometry (LTA) and VerifyNow(R) system in determination of the prevalence of aspirin resistance (AR) and investigated the correlation between its presence and poor outcome (modified Rankin scale >2) in 105 patients with aspirin after acute ischemic stroke (AIS). RESULTS: After 5 days of using aspirin, 15 patients (14.3%) were classified as aspirin-resistance with the use of IPA, 24 patients (22.9%) by the LTA, and 14 patients (13.3%) by VerifyNow. Good agreement between the results of IPA and VerifyNow, was found (R=0.674, P<0.01). The concordance rate of AR detection was high between VerifyNow and IPA (k=0.72, P<0.01), albeit quite low between LTA and IPA. Regarding on its influence on clinical outcome after AIS, there wasn't any significant relationship between occurrence of poor outcome and the presence of AR in three platelet function assays. CONCLUSION: This study reveals that the incidence of AR in AIS might be highly test-specific. IPA seems to be similar to VerifyNow as a platelet function test.

PURPOSE: Medical direction is an integral part of proper prehospital care, which is performed by EMS providers. In Gyunggi province, a number of measures have been implemented to improve the direct medical direction system. We aimed to report on the process and results of the newly implemented medical direction system. METHODS: This is a descriptive analysis of the newly implemented medical direction system for community EMS providers from June 2014 to October 2014. Direct medical direction was requested by emergency medical technicians (EMTs) during the study period, as follows: when a destination hospital was selected, EMTs requested medical direction from the physicians at the destination hospital. During the study period specially-trained advanced EMTs were permitted to perform intravenous (IV) access for fluid or glucose infusion without direct medical direction. EMTs were asked to complete records when they requested direct medical direction and performed IV access without medical direction. These records were collected and used in the analysis. RESULTS: Of 5949 direct medical direction requests, 5527 were analyzed; 2958 (53.5%) cases were requested to the destination hospitals, 2569 (46.5%) were requested to the centralized dispatch center. 'Patient evaluation' was the most common reason for EMTs to request medical direction to the destination hospitals (1680, 54.4%) and centralized dispatch center (980, 38.1%). EMTs' degree of satisfaction did not differ significantly between destination hospitals and the centralized dispatch center (4.12+/-0.82 and 4.09+/-0.84, p=0.053). IV access rate for hypotensive patients increased 6.1% during the study period compared to the same period of 2013 (17.6% and 11.5%, p<0.01). CONCLUSION: We found that it is feasible to request direct medical direction to the destination hospitals and perform IV access for fluid or glucose infusion without direct medical direction for specially-trained advanced EMTs. Continuing efforts to establish an optimized medical direction system would be required for proper pre-hospital care.

Since the first case of gastric serrated adenoma found in 2001, 35 additional cases have been reported. Among these cases, 26 cases were associated with invasive adenocarcinoma within the serrated adenoma. Gastric serrated adenoma when compared with traditional adenoma has close correlation with invasive carcinoma. Serrated colorectal polyps are classified as hyperplastic polyps, sessile serrated adenoma/polyps, and tranditional serrated adenoma (TSA) depending on histological features. Two distinct phenotypes of TSA in the colon and rectum are reported. Those are unlocked serrated crypts (US-TSA) and ectopic crypt formations (ECFs). All gastric serrated adenoma are TSA in historical aspect and ECFs on phenotype. Whereas gastric adenomas are reported with high frequency in the antrum, gastric serrated adenomas are founded in the body and cardia. We report a case of a 60-year-old woman receiving endoscopic submucosal dissection for gastric serrated adenoma with adenocarcinoma discovered during routine screening.

Localized nodular myositis is an uncommon benign inflammatory myopathy of unkonwn cause affecting skeletal muscle and, presenting as a localized painful swelling within the soft tissue of an extremity. Histological examination reveals lymphocytic infiltration, scattered muscle fiber necrosis and regeneration, and interstitial fibrosis. MRI finding is an enhancement with increased signal intensity around the lesion. We report two cases of localized nodular myositis presenting as pseudothrobothrombophlebitis. We believe this is the first case report of localized nodular myositis in Korea.

BACKGROUND: The accurate identification of cytogenetic abnormalities in multiple myeloma (MM) has become more important over recent years for the development of new diagnostic and prognostic markers. In this study, we retrospectively analyzed the cytogenetic aberrations in MM cases as an initial assessment in a single institute. METHODS: We reviewed the cytogenetic results from 222 patients who were newly diagnosed with MM between January 2000 and December 2015. Chromosomal analysis was performed on cultured bone marrow samples by standard G-banding technique. At least 20 metaphase cells were analyzed for karyotyping. RESULTS: Clonal chromosome abnormalities were detected in 45.0% (100/222) of the patients. Among these results, 80 cases (80.0%) had both numerical and structural chromosome abnormalities. Overall hyperdiploidy with structural cytogenetic aberrations was the most common finding (44.0%), followed by hypodiploidy with structural aberrations (28.0%). Amplification of the long arm of chromosome 1 and -13/del(13q) were the most frequent recurrent abnormalities, and were detected in 50 patients (50.0%) and 40 patients (40.0%) with clonal abnormalities, respectively. The most common abnormality involving 14q32 was t(11;14)(q13;q32), which was observed in 19 cases. CONCLUSION: These findings demonstrate that myeloma cells exhibit complex aberrations regardless of ploidy, even from a single center in Korea. Conventional cytogenetic analysis should be included in the initial diagnostic work-up for patients suspected of having MM.
