Periductal mastitis arises from major ducts. Radiographic reports describing the phases of duct ectasia and secretory calcifications, have been published, but descriptions of the phases of periductal mastitis are rare. We report the mammographic and ultrasonographic findings of periductal mastitis in a 30-year-old woman who presented with a breast lump.

OBJECTIVE: This study was conducted to perform histomorphometric evaluations of the bone surrounding orthodontic miniscrews according to their proximity to the adjacent tooth roots in the posterior mandible of beagle dogs. METHODS: Four male beagle dogs were used for this study. Six orthodontic miniscrews were placed in the interradicular spaces in the posterior mandible of each dog (n = 24). The implanted miniscrews were classified into no loading, immediate loading, and delayed loading groups according to the loading time. At 6 weeks after screw placement, the animals were sacrificed, and tissue blocks including the miniscrews were harvested for histological examinations. After analysis of the histological sections, the miniscrews were categorized into three additional groups according to the root proximity: high root proximity, low root proximity, and safe distance groups. Differences in the bone–implant contact (BIC, %) among the root proximity groups and loading time groups were determined using statistical analyses. RESULTS: No BIC was observed within the bundle bone invaded by the miniscrew threads. Narrowing of the periodontal ligament space was observed in cases where the miniscrew threads touched the bundle bone. BIC (%) was significantly lower in the high root proximity group than in the low root proximity and safe distance groups. However, BIC (%) showed no significant differences among the loading time groups. CONCLUSIONS: Regardless of the loading time, the stability of an orthodontic miniscrew is decreased if it is in contact with the bundle bone as well as the adjacent tooth root.

Objectives: We aimed to investigate the demographics and medical management factors associated with dependence on hypnotics among outpatients with neurological disorders and insomnia. Methods: We reviewed electronic medical records of patients who received an initial hypnotic prescription between January 2014 and January 2016 and had later visited a neurological outpatient clinic before January 2018. We assessed patient demographics, the effectiveness of hypnotics, prescription periods, and hypnotic intake methods during the follow-up period. Results: Of 242 patients diagnosed with insomnia, we enrolled 114 patients (more women than men, at 61.4 versus 38.6%) who visited outpatient clinics regularly during the follow-up period. The mean age at onset was 65.8 ± 14.4 years. The most frequent neurological disorder was cerebrovascular disease, followed by neurodegenerative disease. During the 2-year period, 35.9% of participants remained hypnotics-free. Patients on zolpidem showed significantly greater insomnia improvement with hypnotic discontinuation than those on benzodiazepines and combination therapy (p=0.004). However, the type of hypnotics and demographic factors were not found to be independent risk factors. Multivariable analysis showed that longer periods between regular visits and a lower ratio of receiving number of pills to the time interval (days) between regular visits were independent risk factors for dependence on hypnotics. Conclusions: We found that low-dose and/or intermittent intake of hypnotics as well as frequent doctor visits could prevent dependence on hypnotics. It is important to establish the best practical guidelines for medical hypnotics management in outpatient primary care settings, including neurological clinics.

A study was done on 200 patients with a diagnosis of calcium oxalate stone and 50 cases of control group to evaluate the chemical relationships between stone formation and a 24-hour excretion or calcium. oxalate, uric acid and citrate. This study was also evaluated by comparing urinary concentrations and total daily output of the above metabolites. Among the 200 patients metabolic disorders included hypercalciuria in 34 (17.0%), hyperoxaluria in 8 (4.0%), hyperuricosuria in 43 (21.5%) and hypocitraturia in 128 (64.0%). The total output of calcium, oxalate, uric acid, citrate were significantly different (p<0.01) and also showed significant differences in the those concentrations between these two groups. Therefore, it is confirmed that the concentration of stone metabolite is also a influential factor of the stone formation as like as total daily output.

Ectopic pancreas is commonly located at stomach, duodenum and jejunum. It is a relatively rare entity and is usually of no clinical importance which especially is a very rare source of massive upper gastrointestinal bleeding. We have recently experienced a case of an ectopic pancreas in the second portion of the duodenum which was proven to be a source of massive gastrointestinal bleeding by duodenoscopy and was confirmed by surgical exploration.

PURPOSE: Hepatic atrophy has been recognized as a complication of hepatic and biliary disease but we have often found it in follow up CT after transcatheter arterial embolization {TACE). The purpose of this study is to evaluate the characteristics of hepatic atrophy after TACE. MATERIAL AND METHODS: Of 53 patients who had TACE, We evaluated the relationship between the incidence of hepatic atrophy and the number of TACE, and also evaluated the average number of TACE in patients with hepatic atrophy. Of 20 patients who had received more than average number of TACE for development of hepatic atrophy (2 times with portal vein obstruction, 2.7 times without portal vein obstruction in this study), we evaluated the relationship between the tipiodol uptake pattern of tumor and the incidence of hepatic atrophy. RESULTS: There were 8 cases of hepatic atrophy (3 with portal vein obstruction, 5 without portal vein obstruction), average number for development of hepatic atrophy were 2.5 times. As the number of TACE were increased, the incidence of hepatic atrophy were also increased. Of 20 patients who received more than average number of TACE for development of hepatic atrophy, we noted 6 cases of hepatic atrophy in 11 patients with dense homogenous lipiodol uptake pattern of tumor and noted only 1 case of hepatic atrophy in 9 patient with inhomogenous lipiodol uptake pattern. CONCLUSION: Hepatic atrophy was one of the CT findings after TACE even without portal vein obstruction. Average number of TACE was 2.5 times and risk factors for development of hepatic atrophy were portal vein obstruction, increased number of TACE, and dense homogenous lipiodol uptake pattern of tumor.

The purpose of this study was to evaluate imaging findings of metastatic disease to the breast. We analyzed 15 cases that had been previously examined by radiographic study (comprising a total of 11 mammograms, 13 ultrasounds and 3 chest CT). Primary malignancies included the following: 6 breast cancers, 5 stomach cancers, 2 melanomas, 1 cervical cancer, and 1 lung cancer. Radiologic findings were analyzed and the 15 cases were divided into two groups: hematogeneous and lymphangitic metastasis. Eleven cases were classified as lymphangitic metastasis (73.3%) and 4 cases were hematogeneous metastasis (26.7%). Multiple masses were shown in 13 cases (86.7%), and 12 cases displayed unilateral lesions (80%). There was no evidence of calcification. In the 11 cases with available mammogram, 7 cases (63.6%) revealed multiple masses with well-defined (2 cases, 28.6%) or ill-defined margin (5 cases, 71.4%) and 6 cases (54.5%) showed diffuse increased density and skin thickening. Among the 11 cases that revealed mass lesions on ultrasound, 2 cases showed a well-defined margin (18.2%) and 9 cases showed an ill-defined margin (81.8%). Posterior shadowing of the mass was seen in only 1 case. Four cases (36.3%) showed a minimal echogenic boundary around the mass. Eight cases showed diffuse skin thickening (53.3%). Three cases with chest CT showed multiple masses and/or diffuse skin and trabecular thickening of the breast. In conclusion, the characteristic imaging findings of metastatic disease to the breast are multiple ill-defined masses with a lack of desmoplastic reaction and no calcification, as compared to primary breast carcinoma. The diffuse lesions without evidence of breast mass on mammogram and US could be distinguishable from inflammatory carcinoma of breast origin.
