Usefulness of four-dimensional noise reduction filtering using a similarity algorithm in low-dose dynamic computed tomography for the evaluation of breast cancer: a preliminary study.

Purpose: To evaluate the effects of four-dimensional noise reduction filtering using a similarity algorithm (4D-SF) on the image quality and tumor visibility of low-dose dynamic computed tomography (CT) in evaluating breast cancer.

Materials And Methods: Thirty-four patients with 38 lesions who underwent low-dose dynamic breast CT and were pathologically diagnosed with breast cancer were enrolled. Dynamic CT images were reconstructed using iterative reconstruction alone or in combination with 4D-SF.

Effective Treatment With Oral Propranolol for Congenital Intracranial Hemangioma in a Neonate: A Case Report and Literature Review.

Congenital intracranial hemangiomas are rare benign vascular tumors that develop before birth. Although various treatments, including surgery, steroids, interferon-α, thalidomide, bevacizumab, or propranolol, have been reported, no standard therapy has been established. We report the case of a neonate with congenital intracranial hemangioma and central nervous system symptoms requiring therapeutic intervention.

Levator aponeurosis advancement with partial orbicularis oculi muscle resection for the treatment of Marin Amat syndrome with aponeurotic ptosis: two Case reports.

Marin Amat syndrome is a phenomenon in which eyelids close upon opening of the mouth during the recovery phase after facial nerve paralysis. In this report, we present two surgically treated cases of Marin Amat syndrome with aponeurotic ptosis. Case 1: A 66-year-old man had developed left Bell's palsy a year prior to presentation and underwent rehabilitation at the Neurology Department of Japan Community Healthcare Organization Chukyo Hospital.

Atypical Adult-Onset IgA Vasculitis With Extremely Rare Complications Including Diffuse Alveolar Hemorrhage, Heart Failure, and Stroke.

IgA vasculitis (IgAV) generally occurs in young people and presents with a tetrad of symptoms: purpura, abdominal pain, arthralgia, and nephritis. However, it may have an atypical course without the typical tetrad. Diffuse alveolar hemorrhage (DAH), heart failure, and stroke are known complications of IgAV but are all very rare.

Tsukamurella conjunctivitidis peritonitis diagnosed by 16S rRNA gene sequencing in a patient undergoing peritoneal dialysis.

Peritoneal dialysis (PD)-associated peritonitis remains a serious and life-threatening complication in patients undergoing PD. Majority of peritonitis cases are caused by bacteria, with coagulase-negative Staphylococcus being the most common cause. Tsukamurella species are obligate aerobic gram-positive bacilli found in various environments; however, peritonitis caused by Tsukamurella species in association with PD is rare, with few reports of infections caused by T.
