Background: Despite exponential growth in Indian research, Indian journals have low impact factors. A previous study by one of the authors (CA) of this paper showed that articles published in the Indian Journal of Psychiatry (IJP) under-referenced previously published relevant papers in the same journal. Based on this, we decided to investigate the citation characteristics of contemporary scientific articles published in the Indian Journal of Psychological Medicine (IJPM). Methods: The citation characteristics of scientific articles published in 2018 (Vol 40, issues 1–6) in the IJPM were examined to determine how well the authors cited relevant articles published during the past ten years in the IJPM and the IJP. Results: There were 145 and 142 citation-worthy articles in the IJPM and the IJP, respectively; of these, 85.5% and 65.5%, respectively, had not been cited. Conclusions: Authors publishing in the IJPM under-reference previous relevant research published in the IJPM and IJP. This suggests unawareness of, deliberate disregard of, or even disdain for prior Indian research in the field. Additionally, if Indian researchers do not cite previous Indian research in the field published in Indian journals, the citation metrics of Indian journals will not grow.

“…The occurrence of stroke in patients with LVNC cardiomyopathy is 1-2% per year with a total risk of thromboembolism of about 21-38% [17]. While PCA territory lesions caused by various stroke mechanisms are less well defined compared with those of other vascular territories, cardioembolic etiology may produce significant infarcts due to a lack of collateral flow in the acute process [18][19][20]. The frequency of thromboembolism is variable in adults (13-24%), with AF or systolic dysfunction known to increase the risk of cardioembolic stroke [5,21].…”

Left Ventricular Noncompaction Cardiomyopathy as a Potential Cause of Bilateral Posterior Cerebral Artery Stroke – a Rare and Unique Clinical Occurrence

et al. 2021

Rare co-existence of disease or pathology Background:Bilateral posterior cerebral artery (PCA) occlusions are exceedingly rare, and are considered a devastating phenomenon that presents as cortical blindness. Predominant causes of PCA infarcts include cardiac and arterial embolisms. Left ventricular noncompaction (LVNC) cardiomyopathy is also an extremely rare cardiopathology. Several reports describe stroke as a potential manifestation of LVNC, but bilateral PCA infarcts are likely also caused by underlying LVNC cardiomyopathy, although this has not yet been reported. Case Report:A 63-year-old man presented to the emergency department of an outside hospital with acute vision loss in both eyes and dysarthria. His neurological examination necessitated an emergent stroke evaluation. His electrocardiogram and telemetry at admission did not reveal arrhythmia. He underwent an emergency endovascular thrombectomy at our facility. During the post-intervention stroke workup, a transthoracic echocardiogram with contrast showed left ventricle dilation, with an ejection fraction (EF) of 29%. Subsequent cardiac magnetic resonance imaging confirmed the presence of LVNC cardiomyopathy. He was started on therapeutic anticoagulation (apixaban) and remained stable neurologically during the 3-month followup, with some residual visual field deficits. His cardiac outcome also improved (stress test was unremarkable for any cardiac ischemia, and an echocardiogram showing improved EF of 40%). Conclusions:Our report is distinct, as it presents 2 exceedingly rare events in a patient: the occurrence of simultaneous bilateral PCA infarcts and LVNC cardiomyopathy. Prompt and accurate diagnosis was pivotal to the successful management of both conditions. Prospective studies are warranted to further knowledge of LVNC pathophysiology and the occurrence of stroke in such patients so that comprehensive management plans can be devised.

Auditory Hallucinations as a Rare Presentation of Occipital Infarcts

A stroke is a clinical syndrome characterized by a focal neurologic deficit that can be attributed to a vascular territory within the brain. The presenting features of an acute stroke depends on the area of the brain affected. Although unusual, the presenting feature may include psychosis with auditory and/or visual hallucinations. A 56-year-old female was admitted to the psychiatric unit after threatening her husband with a knife. She reported experiencing altered sensorium for one week with suicidal and homicidal command hallucinations. Given the acute onset, brain images were obtained to rule out an organic etiology. A brain MRI revealed an acute right occipital lobe infarct with hemorrhagic transformation. The patient's symptoms were self-limited, resolving without antipsychotic medications. Psychosis with auditory hallucinations is not commonly reported following stroke. Since histologic and functional alterations in the occipital lobe appear to play a significant role in psychosis of schizophrenics, it is likely that ischemia in the same area may cause similar changes. Familiarity with this rare presentation is important, as it prevents a delay in diagnosis, which may negatively impact the outcome.
