background: premature ovarian failure (pof) is a disorder of multi causal etiology. autoimmunity has been proposed as a mechanism for some cases of ovarian follicle dysfunction which is evident in pof. the aim of this study was to identify the level of auto-antibodies in pof and familial pof patients. materials and methods: in this study, auto-antibodies including anti-ovarian antibody (aoa), a...

Thoracic disk herniation comprises 0.15% of all disk herniation and has various and confusing manifestations.  Among them, radicular pain down the leg could be the rarest presentation, especially if it is the only complaint. On the other hand, finding the relationship between clinical and paraclinical needs require high index of suspension and it is demanding. A 34-year-old patient, who ha...

Parkinson’s disease (PD) is a prevalent neurodegenerative disease that usually affects individuals over 50 years of age. Age at onset in a small subset of PD cases is considerably lower, and these are considered early-onset PD (EOPD) patients. Most PD cases appear sporadic, but approximately 15% are familial, and some of the familial cases exhibit Mendelian inheritance. Genetic analysis of fami...

A 48-year-old man with neurofibromatosis 1 presented with progressive shortness of breath over the course of 4 years. There was prominent kyphoscoliosis. Imaging revealed a large thoracic meningocele compressing the left lung (figure). He then developed progressive lower extremity weakness and a decline in pulmonary function. He underwent drainage, resection, and closure of his thoracic meningo...

Total generalized variation (TGV)-based computed tomography (CT) image reconstruction, which utilizes high-order image derivatives, is superior to total variation-based methods in terms of the preservation of edge information and the suppression of unfavorable staircase effects. However, conventional TGV regularization employs l1-based form, which is not the most direct method for maximizing sp...

Familial Mediterranean fever, an autosomal recessive disorder, is a member of the periodic fever syndromes, and considered to be the most common cause of recurrent febrile episodes in children. It is important to understand the disorder as familial Mediterranean fever falls on a spectrum of various presentations; the recurrent episodes of familial Mediterranean fever may be so severe that the q...
