PurposeThe purpose of this study was to assess the potential benefit of a 5-hydroxytryptamine receptor antagonist, sarpogrelate-based triple antiplatelet therapy (TAPT) in comparison with dual antiplatelet therapy (DAPT) in patients undergoing primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI).Materials and Methods119 patients of STEMI were retrospectively assessed. All patients received aspirin and clopidogrel per standard of care. Among them, 53 patients received an additional loading dose of sarpogrelate and a maintenance dose for 6 months post-PCI (TAPT group), while others did not (DAPT group).ResultsThe rates of complete ST-segment resolution at 30 minutes post-PCI and post-procedural thrombolysis in myocardial infarction flow were not significantly different between the two groups (52.8% vs. 48.5%, p=0.200; 92.5% vs. 89.4%, p=0.080). In addition, no significant differences were observed between the two groups with regard to 30-day and 12-month clinical outcomes (cardiac death, myocardial infarction, stent thrombosis, target vessel revascularization, and severe bleeding). Meanwhile, improvement in left ventricular (LV) systolic function was observed in the TAPT group [ΔLV ejection fraction (LVEF)=17.1±9.4%, p<0.001; Δglobal longitudinal strain (GLS)=−9.4±4.2% , p<0.001] at 6 months, whereas it was not in the DAPT group (ΔLVEF= 8.8±6.5%, p=0.090; ΔGLS=−4.6±3.4%, p=0.106). In multivariate analyses, TAPT was an independent predictor for LV functional recovery (odds ratio, 2.61; 95% confidence interval, 1.16–5.87; p=0.003).ConclusionSarpogrelate-based TAPT improved LV systolic function at 6 months in STEMI patients undergoing primary PCI.

Freezing of gait (FOG) is a common occurrence in patients with Parkinson's disease (PD) that leads to significant limitations in mobility and increases risk of falls. Focused vibrotactile stimulation and cueing are two methods used to alleviate motor symptoms, including FOG, in patients with PD. While effective on their own, the effect of combining both focused vibrotactile stimulation and cueing has yet to be investigated. Two patients, both with a history of PD, suffered from frequent FOG episodes that failed to respond adequately to medication. A novel vibrotactile stimulation device that delivered rhythmic kinesthetic stimuli onto the sternum successfully reduced FOG episodes in both patients and drastically improved their mobility as measured by the Timed Up and Go test. We found that a combination of focused vibrotactile stimulation and cueing was effective in reducing FOG episodes in two patients with PD. Further well-designed prospective studies are needed to confirm our observations.

Acute presentations for dementia, particularly dementia with Lewy bodies (DLB), are rare and can pose diagnostic challenges. We present a case of a 75-year-old woman who was previously fi t, well and independent in all activities of daily living. She had no history of psychiatric, cognitive or memory problems. She presented with 2 weeks of sudden onset confusion, paranoia, dizziness and reduced oral intake. Thorough investigations for causes of delirium including blood tests, cerebrospinal fl uid analysis obtained via lumbar puncture, electroencephalography, computed tomography, and magnetic resonance imaging were within normal limits. Further neurological examination demonstrated she had subtle Parkinsonian signs (cogwheel rigidity, bradykinesia) and was hypersensitive to small doses of antipsychotic (haloperidol and risperidone). A positive dopamine transporter scan was done confi rming a diagnosis of an acute presentation of DLB. She has been commenced on a cholinesterase inhibitor (rivastigmine) and is presently settled in care.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is defined as hyponatremia with inappropriately concentrated urine in a euvolemic patient. SIADH is associated with a wide spectrum of clinical conditions. In the hospital, hyponatremia carries significant mortality with a prolonged duration of inpatient stay. It is imperative that the underlying cause is appropriately investigated and such patients are closely monitored. This article presents a case of difficult-to-treat hyponatremia secondary to SIADH in a patient with a rare isolated central nervous system (CNS) relapse from a non-Hodgkin’s lymphoma (NHL). A relapse, particularly affecting the CNS, carries a poor prognosis. The patient was started on dexamethasone and offered treatment with methotrexate but declined. The hyponatremia failed to respond to fluid restriction and demeclocycline. The hyponatremia responded to a single dose of tolvaptan. Clinicians should have a low index of suspicion for a relapse of lymphoma as a cause of difficult to treat hyponatremia in any patient who has previously had remission from lymphoma treatment.

not time spent per COI (OR 0.89, 95% [0.68 to 1.16], p=0.38, n=11). An ordinal regression model did not show an association between presenter's H-index and total quality score (OR 0.94, 95% CI [0.87 to 1.01], p=0.11, n=11) Conclusion A large minority of presenters did not display a COI statement. Those COI statements that were present were of variable quality. Many were displayed for insufficient time, lacked any verbal explanation or used a small font. These factors may limit the ability of audience members to understand the potential conflicts. Seniority of presenter correlated with number of conflicts but not quality of the COI statement. Strategies should be implemented to ensure all presenters outline whether they have any potential COI in a standardised manner.
