Atypical findings in delayed presentation of unilateral acute idiopathic maculopathy

Unilateral acute idiopathic maculopathy is a rare disease affecting young healthy patients resulting in moderate to severe unilateral visual loss preceded by prodromal flu-like illness. We present a case of delayed presentation of unilateral acute idiopathic maculopathy associated with hand, foot and mouth disease.

Cardiac G-protein-coupled receptor kinase 2 ablation induces a novel Ca2+ handling phenotype resistant to adverse alterations and remodeling after myocardial infarction

G-protein-coupled receptor kinase 2 (GRK2) is a primary regulator of β-adrenergic signaling in the heart. G-protein-coupled receptor kinase 2 ablation impedes heart failure development, but elucidation of the cellular mechanisms has not been achieved, and such elucidation is the aim of this study.

Use of a painless external fixator for unilateral mandibular fracture repair in nine equids

OBJECTIVE: To report use of a pinless external fixator (PEF) for unilateral mandibular fractures in 9 equids. STUDY DESIGN: Case series. ANIMALS: Equids (n=9) with unilateral mandibular fractures. METHODS: All fractures were stabilized with the AO/ASIF PEF using a minimum of 4 clamps, under general anesthesia. Fracture configuration, complications, outcome, and owner satisfaction were evaluated. RESULTS: All fractures were stabilized; 2 equids were euthanatized; 1 because of an inability to stand after surgery and 1 because of owner decision after PEF dislodgement. Seven repairs healed with good outcome and owner satisfaction. Complications included dislodgement of the PEF (3), bone sequestration (3), and weight loss (1). Drainage associated with repair resolved after removal of sequestra and clamps. CONCLUSIONS: Stabilization of unilateral mandibular fractures with the PEF in horses was minimally invasive with minimal risk of tooth root interference; however, after care is time consuming. CLINICAL RELEVANCE: PEF is an alternative technique for stabilizing unilateral mandibular fractures in equids.

Mitral isthmus ablation with and without temporary spot occlusion of the coronary sinus: a randomized clinical comparison of acute outcomes

To evaluate the safety and outcomes of mitral isthmus (MI) linear ablation with temporary spot occlusion of the coronary sinus (CS). Background: CS blood flow cools local tissue precluding transmurality and bidirectional block across MI lesion.

Disparate activation of the coronary sinus and inferior left atrium during atrial tachycardia after persistent atrial fibrillation ablation: prevalence, pitfalls, and impact on mapping

Persistent atrial fibrillation (AF) ablation may lead to partial disconnection of the coronary sinus (CS). As a result, disparate activation sequences of the local CS versus contiguous left atrium (LA) may be observed during atrial tachycardia (AT). We aimed to evaluate the prevalence of this phenomenon and its impact on activation mapping.

Is bilateral extended pelvic lymphadenectomy necessary for strictly unilateral invasive bladder cancer?

We determined the necessary extent of pelvic lymph node dissection in patients with strictly unilateral bladder cancer.
