Lifelong cardiovascular care in Turner syndrome: two cases with review of literature.

Cardiovascular disease is one of the most important complications in girls and women with Turner syndrome (TS). Although the latest international guideline provides useful suggestions for the management of cardiovascular diseases in TS, some unknown cardiac conditions warrant physicians' attention and awareness. Here, we have reported two adult cases wherein significant cardiovascular diseases were detected during the transition period. The first case patient was diagnosed with aortic crank deformity and left subclavian artery aneurysm at 14 years based on the report of cardiac catheterization, computed tomography angiography, and cardiac magnetic resonance imaging, which had remained undetected by annual evaluations using transthoracic echocardiography (TTE). This case emphasizes the importance of cardiac reevaluation during the transition period. The second case patient was diagnosed with moderate mitral valve regurgitation (MR) due to mitral valve prolapse at 18 years through TTE, although the first evaluation at 7 years by TTE detected slight MR without any clinical concerns. The condition however progressed to severe MR at 28 years, requiring mitral valvuloplasty. MR is the most common valve disease worldwide, which makes it challenging to comprehend whether the condition is a complication. However, the condition requiring surgery at this age is extremely rare, which implies the possibility of early progression. Because almost all literature on cardiovascular complications in TS is cross-sectional, further information about longitudinal cardiovascular conditions is vital for optimal care for girls and women with TS. The two cases reported in this article provide significant information for improving lifelong cardiovascular health issues in TS.

Ponatinib-Related Vasospastic Angina.

Tyrosine kinase inhibitors (TKIs) are essential drugs for chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia. Cardiovascular or arteriothrombotic adverse events have been reported in patients treated with TKIs. We report 3 cases of Ponatinib-related vasospastic angina, in which prophylactic administration of nitrates or calcium channel blockers was effective.

Impact of Anticoagulation Therapy on the Risk of Pulmonary Embolism and Bleeding Events in Patients with Isolated Distal Deep-Vein Thrombosis.

The efficacy of anticoagulation for isolated distal DVT (id-DVT) is still uncertain and controversial. The aim of this study was to elucidate the risk of pulmonary embolism (PE) from id-DVT and to investigate the need for anticoagulants.We identified hospitalized patients with id-DVT diagnosed by lower-extremity ultrasonography (LEUS) from January 2013 to December 2013 in our institute. The exclusion criteria were the simultaneous detection of PE, a history of PE and/or DVT, and administration of anticoagulants before DVT detection. We retrospectively investigated the patient characteristics, treatments, occurrence of PE, and bleeding events between the groups with and without anticoagulation.A total of 151 patients met the criteria. The median (IQR) age was 74 (67, 80) years old, and there were 60 (39.7%) men. The median (IQR) observation period was 571 (160, 721) days. Significant differences in patient characteristics were observed for hypertension, operation time, consultation with experts, and follow-up LEUS. During the observation period, only one patient in the no-anticoagulation group who had traumatic cerebral hemorrhaging and was bedridden developed PE (non-massive type). However, there was no statistically significant difference in the occurrence of PE between the groups (log-rank P = 0.569). Bleeding episodes were observed in 9 of 151 (6.0%) patients, and all patients with bleeding events were taking anticoagulants (log-rank P < 0.001).The present retrospective single center study suggests that anticoagulation for id-DVT in inpatients with various backgrounds has a low efficacy to prevent the occurrence of PE and may increase bleeding events.

Granulocyte Colony-stimulating Factor-associated Aortitis on Gallium Scintigraphy.

Aortitis is a rare adverse event associated with granulocyte colony-stimulating factor (G-CSF). Contrast-enhanced computed tomography (CECT) is widely used to diagnose G-CSF-associated aortitis. However, the usefulness of gallium scintigraphy for the diagnosis of G-CSF-associated aortitis is unknown. We herein report a set of pre- and post-treatment gallium scintigrams of a patient with G-CSF-associated aortitis. During the diagnosis, gallium scintigraphy revealed hot spots on the arterial walls that appeared inflamed on CECT. Both the CECT and gallium scintigraphy findings disappeared. Gallium scintigraphy can be a supportive diagnostic tool for G-CSF-associated aortitis, especially in patients with an impaired renal function or allergy to iodine contrast.
