“Background: Bronchial artery (BA) embolization (BAE) is recommended as a minimally invasive therapy for hemoptysis, though some patients recover after only conservative treatment. Objectives: The purpose of our study selleck screening library was to assess the characteristics of BAs using multidetector row computed tomography (MDCT) and identify BAs requiring BAE without BA angiography (BAG). Methods:

We retrospectively studied 41 patients and classified the visualized BAs into groups based on their BAE and bleeding statuses. Patients presenting with massive hemoptysis requiring emergency BAE were excluded. Patients presenting with persistent hemoptysis that was resistant to conservative treatment received BAE. Radiologists measured BA diameters at the ostium, bronchial bifurcation and pulmonary hilum, and also evaluated the degree of vascularization. Results: MDCT enabled visualization of 102 ostia and 96 traceable BAs. Among the

participating patients, 13 had at least one ectopic origin. We obtained a good correlation between BAG and MDCT diameters (r = 0.709, p < 0.001). The diameters of BAs responsible for bleeding and receiving BAE were apparently larger in each measured segment than those that were not (p < 0.05). Moreover, Y-27632 mw the diameters of arteries receiving BAE remained largely unchanged from the origin to the hilum and through the mediastinum. BAs with low MDCT scores were significantly less likely to required BAE than those with high scores (p = 0.004), and in multiple logistic regression analysis, ostium diameter and bleeding status were independent

predictive factors for BAE. Conclusions: Evaluation of BAs on MDCT could be useful for identifying the anatomical characteristics of bleeding-related BAs and determining whether BAE is indicated or whether Selleckchem BYL719 conservative treatment is sufficient.

“Aim: The mucocutaneous changes observed during vitamin B12 deficiency in children have been published only as case studies and small case series. In this study, we aimed to demonstrate the frequency of mucocutaneous changes (particularly hyperpigmentation) seen during vitamin B12 deficiency and resolving time of these symptoms with vitamin B12 treatment.

Material and methods: This prospective study was conducted at the pediatrics outpatient clinic of Harran and Yuzuncu Yil University Faculty of Medicine, among 57 patients, aged between 6 and 24 months, who were diagnosed with vitamin B12 deficiency following various examinations and tests. A detailed examination was performed in respect to skin and mucosal findings. Patients with vitamin B12 deficiency were administered intramuscular cyanocobalamin. Prospective examination was continued, and resolving time of symptoms after treatment was recorded.

Results: The mean age of the patients enrolled in the study was found to be 12.75 +/- 4.75.
