In Asia, mammography following the injection of foreign materials into the breasts for cosmetic augmentation is frequently seen and diagnosis based on the typical radiologic findings is straightforward. We report the unusual radiologic findings in two patients with foreign body granulomas caused by injected foreign materials and discovered incidentally during screening work up. The mammographic findings were bilateral, hyperdense, spiculated masses, with occasional microcalcification, and at sonography, markedly hypoechoic, spiculated solid masses, located near the pectoralis muscle and partly extending into it, were observed. These radiologic findings mimicked malignancy.

Cell-free DNA (cfDNA) screening for fetal aneuploidies is clinically available and exhibits better performance than conventional serum screening tests. However, data on the clinical performance of cfDNA screening in twin pregnancies are limited. In this review, we summarized the clinical performance and evaluated the feasibility of cfDNA screening in twin pregnancies based on recent studies and recommendations. The performance of cfDNA screening for trisomy 21 in twin pregnancies is similar to that in singleton pregnancies. Specifically, cfDNA screening has a higher detection rate and lower false-positive rate compared with conventional serum screening. Consequently, recent international guidelines from several academic communities have recommended that cfDNA screening for aneuploidy in twin pregnancies could be considered. Moreover, twin pregnancies can present with specific conditions, such as different zygosities and vanishing twins; therefore, individualized counseling and management are required. Further clinical studies with more twin pregnancies are required for a more accurate analysis.

PURPOSE: Transumbilical laparoscopic-assisted appendectomy (TULA) is a single incision technique that uses a combined intra- and extracorporeal method. The aim of this study was to compare surgical outcomes of TULA with conventional 3-port laparoscopic appendectomy (LA). METHODS: A retrospective review of medical records between 2010 and 2014 identified 303 pediatric patients who underwent LA with uncomplicated acute appendicitis. Of these, 85 patients underwent TULA and 218 patients underwent conventional LA. Demographic data, clinical characteristics, perioperative outcomes and postoperative complications were compared between the 2 groups. RESULTS: The mean operation time in the TULA group was 30.39 minutes, which was significantly shorter than that of the LA group (47.83 minutes) (P < 0.001). The first day of oral intake after surgery was earlier (1.05 days vs. 1.32 days; P < 0.001) and the length of hospital stay was also shorter (2.54 days vs. 3.22 days; P < 0.001) for the TULA group than the LA group. Furthermore, the postoperative complication rate was lower in the TULA group (1 of 85, 1.25%) compared to the LA group (19 of 218, 8.7%) (P = 0.018). CONCLUSION: In conclusion, TULA procedure is recommended for uncomplicated appendicitis in children due to its simplicity and better postoperative outcomes.

PURPOSE: To analyze retrospectively the abnormalities visible on the false-negative screening mammograms of patients with breast cancer and to determine the performance of computer-aided detection (CAD) in the detection of cancers. MATERIALS AND METHODS: Of 108 consecutive cases of breast cancer diagnosed over a period of 6 years, of which previous screening mammograms were available, 32 retrospectively visible abnormalities (at which locations cancer later developed) were found in the previous mammograms, and which were originally reported as negative. These 32 patients ranged in age from 38 to 72 years (mean 52 years). We analyzed their previous mammographic findings, and assessed the ability of CAD to mark cancers in previous mammograms, according to the clinical presentation, the type of abnormalities and the mammographic parenchymal density. RESULTS: In these 32 previous mammograms of breast cancers (20 asymptomatic, 12 symptomatic), the retrospectively visible abnormalities were identified as densities in 22, calcifications in 8, and densities with calcifications in 2. CAD marked abnormalities in 20 (63%) of the 32 cancers with false-negative screening mammograms; 14 (70%) of the 20 subsequent screening-detected cancers, 5 (50%) of the 10 interval cancers, and 1 (50%) of the 2 cancers palpable after the screening interval. CAD marked 12 (50%) of the 24 densities and 9 (90%) of the 10 calcifications. CAD marked abnormalities in 7 (50%) of the 14 predominantly fatty breasts, and 13 (72%) of the 18 dense breasts. CONCLUSION: CAD-assisted diagnosis could potentially decrease the number of false-negative mammograms caused by the failure to recognize the cancer in the screening program, although its usefulness in the prevention of interval cancers appears to be limited.

A primary angiosarcoma is a very rare condition, accounting for 0.04% of all malignant tumors of the breast. It is known to have a poor prognosis and recurrence and distant metastasis are common. We report two cases of primary angiosarcoma. They were first diagnosed in 29 years old & in 34 years old. Preoperative evaluation provided an indication of the disease, and no evidence of merastasis was seen. Both patients underwent a total mastectomy. Radiation therapy was performed as an adjuvant treatment in one patient and in the case of recurrence in the other. Pathologic findings are reviewed and described. The diagnostic approach and treatment options from the literature are discussed.

PURPOSE: To evaluate the clinical and radiographic findings of localized foreign body (FB) granulomas onmammograms. MATERIALS AND METHODS: This study involved 13 patients with localized FB granulomas on mammograms;their history of mammoplasty or other plastic procedures was obtained by telephone interviews. Two radiologistsanalyzed the location and morphology of FB granulomas and the presence of associated linear densities orparenchymal distortion on mammograms. Four patients underwent ultrasonography. RESULTS: No patient had a historyof mammoplasty. All 13, however, had a history of plastic procedure, three to 22 (average, 12) years previously,as follows : foreign materials including silicone liquid and oil such as paraffin been injected into the anteriorneck area of nine patients, the infra-auricular area of two, and the nose of two. Multiple small, high-density,flocculent nodules representing FB granulomas were distributed bilaterally in nine patients; they were noted inthe upper inner portion of 11 of 26 breasts. In eight patients, mammograms showed linear opacities suggestingfibrosis. There was no calcification or parenchymal distortion. Though in three cases, the masses were palpable.Ultrasonography revealed several anechoic nodules with posterior enhancement in subcutaneous fatty layers, and inone, 0.2cc of oil droplet had been aspirated under ultrasonographic guidance. CONCLUSION: Localized FB granulomasof the breast could be caused by the migration of FB from cervicofacial areas. Mammography showed characteristicdistribution of upper inner portions, and the findings were similar to those of mild interstitial mammoplasty.

OBJECTIVE: To investigate the value of ultrasound-guided tattooing localization (US-tattoo) using a charcoal suspension for breast lesions. MATERIALS AND METHODS: One hundred sixty-four nonpalpable breast lesions in 134 patients (mean age 47 years; range 30-74 years) were marked with a charcoal suspension under US guidance. The medical records associated with the US-tattoo, the pathology results and the follow-up US results were reviewed. RESULTS: The average size of the localized lesions was 1.0 cm. The procedure time was < 5 minutes (range, 2-10 minutes) per lesion. The US-tattoo was well tolerated in all cases. The only technical difficulty encountered was a needle tip blockage caused by a large charcoal particle (4.9%). The surgeon easily identified the tattoo with the exception one case. In addition, surgery could be safely delayed from one to 57 days after the making US-tattoo. The pathology result was benign in 108 cases, borderline in five, and malignant in 51. The excised specimen was < 4 cm in 76.6% (82/107) of the benign cases (mean; 2.7 cm). The pathologist could identify the mass around the tattoo and was able to make a specific diagnosis in 81.3% (87/107) of benign lesions. The only complication encountered was residual charcoal marking along the incision scar (3.6%). All follow-up US documented the removal of the lesions. CONCLUSION: An US-tattoo for nonpalpable breast lesions is a very simple and accurate method that can help surgeons design and schedule an open biopsy.

BACKGROUND: The food exchange-based meal plan is effective in controlling dietary energy intake with a macronutrient balance. However, it is difficult to practice for relatively low-literacy patients. As an alternative, we developed a system employing a standardized-sized bowl and investigated its effectiveness on achieving proper energy intake and macronutrient composition and patient compliance, compared to the conventional food exchange system in Korean type 2 diabetes patients. METHODS: Eighty subjects with type 2 diabetes were assigned to both the novel bowl-based meal plan group (BG) and the food exchange-based meal plan group (ExG). BG received limited simple instructions for the plan. Time spent for plan instruction was 10 min for BG and 40 min for ExG. Dietary energy and macronutrient intake were estimated with 3-day dietary records and patient comprehension of the plan was estimated with a 5-point Likert scale. RESULTS: After 12 weeks, dietary energy compliance showed no difference between the groups (BG: 103 +/- 10%, ExG: 101 +/- 17%). Both groups showed significant reduction in carbohydrate and protein intake and there was no difference in the proportion of carbohydrate, protein and fat in energy intake between the groups despite the shorter instruction time for BG. Following the instruction period, there was no difference in the understanding score between the groups. CONCLUSION: This bowl-based plan was equally effective as the food exchange-based plan in controlling dietary energy intake and macronutrient composition, as well as patient comprehension and compliance. Our novel plan may allow for more cost-effective methods in terms of time needed for plan instruction.

PURPOSE: Granulomatous mastitis is a benign inflammatory disease of the breast and its etiology is not clearly defined. In 1972, Kessler and Wolloch described the microscopic features of granulomatous mastitis, but frequently it mimics a carcinoma in a clinical setting. This study was performed to determine the modalities that are important for the diagnosis and the treatment of granulomatous mastitis. METHODS: We studied 12 patients who were diagnosed as having granulomatous mastitis based on pathology. Age, parity, time from last delivery, number of operations, past history of breast feeding and oral contra ceptives, radiologic findings, and cytologic results were retrospectively evaluated. In two recent cases, a polymerase chain reaction (PCR) for mycobacterium tuberculosis was performed to exclude tuberculous mastitis. RESULTS: Among the 12 patients, 8 were in the thirties, 2 in the twenties, 1 in the forties and 1 in the fifties. Of the 12 patients, 9 patients had breast fed and 2 patients had used oral contraceptive pills previously. No patients were suffered from pulmonary tuberculosis. The mean number of deliveries was two. The time from last delivery were varied from 3 weeks to 24 years but most were within 6 years. The location of the lesions were the upper outer quadrant in 6, upper inner quadrant in 3, inner area in 1, lower outer quadrant in 1 and lower inner quadrant in 1 patient. The mean size of the lesions was 3.52 cm. Preoperative mammography was not helpful in finding granulomatous mastitis. Ultra sonographically multiple clustered, contiguous tubular hypochoic lesions suggested the possibility of the disease. Furthermore, fine needle aspiration cytology showed epithelial histiocytes or giant cells and could be used to diagnose granulomatous mastitis. Cultures of microorganisms were sterile, and AFB stainings were all negative. Tuberculous mastitis was excluded by PCR in 2 cases. Surgical resection of the affected tissue was performed in 8 patients and steroid therapy was performed in the remaining 4 who had been surgically treated in other clinics before. All excision cases, except one, were cured. Among the patientsfor whom steroid therapy was used, 1 patient was cured, 1 had a recurrence and the remaining 2 are now under treatment. CONCLUSION: Although rare, granulomatous mastitis could be diagnosed with the aid of ultrasonography and cytology. Surgical excision of the affected tissue and long-term steroid therapy could be used to treat the disease.
