Amyloidosis is a rare disease characterized by the formation of pathological protein deposits in organs or tissues. It is typically a systemic disease which can occur in a localized form. Amyloidosis of the breast is uncommon. Common mammographic findings of breast amyloidosis are multiple nodules with or without calcifications. We report a case of primary localized breast amyloidosis presenting suspicious microcalcifications on mammography without associated masses. Mammography in a 72-year-old woman displayed multiple, linearly distributed, irregular and rod-like calcifications in the subareolar area of the left breast. The patient underwent surgical excision under mammo-guided needle localization and the pathology was confirmed to be breast amyloidosis.

OBJECTIVETo screen out the sonogram features for the differential diagnosis of benign and malignant thyroid small nodules (≤ 1.0 cm) by Logistics regression analysis, to establish the binary Logistic regression model of sonogram features as independent variable and investigate the value of wall configuration of ultrasonogrophic nodules in the differential diagnosis of benign and malignant thyroid small nodules.
METHODSA total of 208 thyroid nodules ≤ 1.0 cm in diameter in 190 patients were evaluated. With postoperative pathological examination or fine needle aspiration biopsy, 106 nodules were confirmed as benign and 102 as malignant. Ultrasonic features of thyroid nodules were evaluated for the differential diagnosis of benign and malignant small thyroid nodules based on pathological diagnosis as a gold standard, a Logistic model was obtained, and the odds ratio of variables were compared. The margin of thyroid nodule was divided into regular or irregular margin, and the latter was divided further into four subtypes: strip, triangular, antler and papillary. The border was divided into clear, fuzzy or both. The periphery was divided into those with normal and abnormal echo;. The calcification included no calcification, microcalcification and non-microcalcification.
RESULTSFour statistically significant features were obtained finally by Logistics regression analysis, including margin, border, periphery and calcification. A formula was constructed by two-variables logistic regression analysis and probability of malignancy = 1/(1 + e - z), in which z = 5.026 × margin + 4.218 × border + 4.024 × periphery + 3.892 × calcification - 15.247. The odds ratio of margin was higher than the other independent variables.
CONCLUSIONSLogistics regression analysis indicates that the calcification, border, periphery, and especially margin of thyroid nodules are significant features for differentiating benign and malignant thyroid nodules. The margin score was more intuitionistic for the differentialtion of benign and malignant thyroid nodules.

A 16-year-old female patient with systemic lupus erythematosus (SLE) presented with abdominal pain and oliguria, after one month of hospital treatment with methylprednisolone and cyclophosphamide. Computed tomography of the abdomen revealed the calcification of bilateral superior segmental ureteral wall. Computed tomography urography revealed stenosis of bilateral ureters. This calcification may be associated with lupus-induced inflammatory reaction of ureteral endomembrane. By receiving the ureteral catheters, her abdominal pain and oliguria had been completely resolved. After discharge, she underwent the surgery of cutaneous ureterostomy in the local hospital. During two years follow-up, her condition is stable without any symptom of the urinary system.

OBJECTIVESTo investigate the diagnosis and treatment cervical disc calcification in children.
METHODS13 children with cervical disc calcification were analysed retrospectively. Cervical pain was observed after influenza in 5 children, suddenly cervical pain in 3, sudden wryneck in 3 cases. Two children with this disease were accidentally found after injury.
RESULTS14 calcifications of cervical disks were found in 13 children. Clinical symptoms disappeared after symptomatic management. Calcification disappeared in 5 months.
CONCLUSIONSCervical disc calcification in children is a kind of benign self-limited disease. Correst understanding of pathophysiologic course of this disease helps to avoid unnecessary surgery.

In order to preprocess mammograms for diagnosing the early cases of breast cancer and improving the computational efficiency in the computer-aided detection of micro-calcifications in mammograms, we have advanced a novel processing technique for the extraction of micro-calcification region of interest (MROI). The proposed method is based on a three-step procedure: (1) the mammogram is divided into sub-images of the same size; (2) the wavelet multi-resolution method is conducted on the sub-images, and the parameters related to wavelet transform and threshold T are discussed according to rho; (3) the classification of sub-images is determined by T. It is tested with 20 mammograms and the results show that the method can achieve a true positive rate as high as 89.7% with a false positive rate as low as 2.1%.
