In this paper, an iterative method is proposed for solving matrix equation $sum_{j=1}^s A_jX_jB_j = E$. This method is based on the global least squares (GL-LSQR) method for solving the linear system of equations with the multiple right hand sides. For applying the GL-LSQR algorithm to solve the above matrix equation, a new linear operator, its adjoint and a new inner product are dened. It is p...

Ollier’s syndrome, a variant of multiple enchondromatosis, is a rare disease with an estimated prevalence of 1/100,000, characterized by multiple enchondromas, asymmetrically involving small bones of the hands and feet, especially the proximal phalanges. Intracranial enchondromas, such as those arising from the skull base are extremely rare. Herein, we report a 25-year-old female, known case of...

Abstract. This paper focuses on total least squares (TLS) problems AX ≈ B with multiple right-hand sides. Existence and uniqueness of a TLS solution for such problems was analyzed in the paper [I. Hnětynková, M. Plešinger, D. M. Sima, Z. Strakoš, and S. Van Huffel (2011)]. For TLS problems with single right-hand sides the paper [C. C. Paige and Z. Strakoš (2006)] showed how a necessary and suff...

Recently multiple cutaneous leiomyomas, uterine leiomyoimatosis and renal cancer have been described as a cancer syndrome with autosomal dominant pattern of inheritance.We report a 79-year-old man who presented with multiple hyperkertotic erythematous nodules on his right leg with histological diagnosis of pilar leiomyoma. In his past medical history several systemic co...

conclusions our study suggests that the personality traits of patients with ms and healthy individuals are not significantly different. patients with ms are likely to use the same coping strategies as healthy individuals, except in the subscale of distancing. results no significant differences in personality characteristics were observed between patients and healthy controls (all p > 0.05). onl...

A 54-year-old man was transferred with sigmoid colon cancer combined with multiple bilobar liver metastases. Nine metastases were in the left lobe and 5 metastases were in the right lobe. After low anterior resection, all 9 lesions in the left lobe were completely removed by wedge resections. Because the remnant liver volume after multiple wedge resection of the left lobe was not sufficient to ...

multiple myeloma (mm) is characterized by progressive proliferation of malignant plasma cells, usually initiating in the bone marrow. mm can affect any organ; a total of 7 - 18% of patients with mm demonstrate extramedullary involvement at diagnosis. non-secretory multiple myeloma (nsmm) is a rare variant that accounts for 1 - 5% of all cases of multiple myeloma. the disease is characterized by...

A 27 year old woman who presented with upper abdominal pain was found on ultrasonography to have multiple liver cysts consistent with hydatid disease. Three years previously she had undergone evacuation of multiple infected liver cysts thought to be due to hydatid disease. Computed tomographic scanning supported the diagnosis of hydatid disease affecting the right lobe of the liver. At laparoto...

A 46-year-old woman with multiple myeloma presented with neurological symptoms in the right upper extremity. After MR imaging of the cervical spine failed to show the cause of her symptoms, Ga-67 scintigraphy demonstrated increased uptake in multiple areas including the right supraclavicular region and bilateral lower extremities. Histology of the specimen obtained from the left thigh proved so...
