Background: Spontaneous isolated dissection of the posterior inferior cerebellar artery (PICA) is rare and presents with variable clinical course and prognosis. We report a case of spontaneous isolated PICA dissection presenting with lateral medullary infarction. Case Report: A 57-year-old female patient presented with right leg ataxia, headache, nausea and vomiting with a past medical history ...

OBJECTIVES Pica has been studied in India and elsewhere for more than 100 years, yet no compelling and empirically well-supported explanation for it has emerged. Amylophagy, sometimes considered a type of pica and sometimes studied separately, is less frequently investigated and also lacks a convincing explanation. This study used a biocultural approach to test three hypotheses of pica and amyl...

The posterior inferior cerebellar artery (PICA) usually originates from the distal vertebral artery . Many variations in its origin and course have been observed in association with anomalies of the anterior inferior cerebellar artery (AICA) (1 ). However, as far as we know, angiographic evidence of anomalous origin of the PICA from the posterior meningeal artery (PMA) has not been reported pre...

Objectives: Pregnancy pica is harmful to the mother and her baby. This study aimed update global prevalence of in pregnant women. Methods: Scopus, Science Direct, Wiley online, Google Scholar, PubMed databases were searched for observational studies until July 2021. search was done with keywords "pregnancy pica", "prevalence "pica frequency". After evaluating extracted based on inclusion exclus...

OBJECTIVES Arterial variation is common in the vertebral artery, and simple occlusion of the left subclavian artery may result in brain infarction, especially when it terminates in the posterior inferior cerebellar artery (PICA). We report the results of preoperative vertebral artery evaluation by magnetic resonance angiography (MRA) and its impact upon operative strategy. METHODS Among the 2...

Geophagia is a condition involving the consumption of mud and is a form of eating disorder known as pica. Pica is an unusual craving for ingestion of either edible or inedible substances. Although, pica is not linked to solvent abuse, here we report a middle aged lady with mud eating that responded to selective serotonin-reuptake inhibitors and cognitive behavior therapy.

BACKGROUND AND PURPOSE Results of endovascular treatment of PICA aneurysms are not well established. The purpose of this study was to report incidence, clinical presentation, and outcome of endovascular treatment in 46 patients with 47 posterior inferior cerebellar artery (PICA) aneurysms. MATERIALS AND METHODS Of 2169 aneurysms treated between January 1995 and March 2007, 60 were located on ...

Multi-modal data analysis techniques, such as the Parallel Independent Component Analysis (pICA), are essential in neuroscience, medical imaging and genetic studies. The pICA algorithm allows the simultaneous decomposition of up to two data modalities achieving better performance than separate ICA decompositions and enabling the discovery of links between modalities. However, advances in data a...

Cisplatin is an effective chemotherapeutics against a wide range of cancers. However, it causes significant nausea and vomiting which limit its usefulness. In the present study, the effects of methanolic root extract of Pluchea lanceolata (DC.) C. B. Clarke , asteraceae ( MPL ) was investigated against cisplatin-induced nausea using a rat pica model. In rat pica model, rats react to cispla...

Six cases of unclippable vertebral aneurysms were treated by therapeutic occlusion of the proximal vertebral artery. In three cases, the vertebral artery was clipped proximal to the posterior inferior cerebellar artery (PICA), and all of these patients had a postoperative embolic complication or a fatal subarachnoid hemorrhage. In two cases, the vertebral artery was clipped distal to the PICA a...
