Sebaceous Carcinoma of the Eyelid
No full textSebaceous gland carcinoma of the eyelid is a very rare, slow growing tumor arising from the meibomian glands. In contrast to squamous cell carcinoma and basal cell carcinoma which arise frequently from the lower lid, sebaceous carcinoma arises from the upper lid where meibomian glands are more numerous. We present a case of sebaceous carcinoma in an elderly lady who presented with a slow growing tumor in the lateral third of the lower lid, without any lymph node metastasis. The tumor was treated by wide excision and the eyelid was reconstructed by Tenzel semilunar flap
Cytomorphological Diagnosis of Giant Cell Tumour of Distal End Radius in Elderly Patient
No full textGiant cell tumours (GCTs) of bone have been described as the most challenging benign bone tumors. It is very unusual for GCT to occur in patients younger than 20 yrs or older than 55 years. GCT is seen with a slightly increased frequency in females. The typical giant cell tumor (GCT) is a solitary neoplasm that occurs in the epiphysis or metaphysis of long bones. The most common sites include the distal femur, proximal tibia and distal radius. The sacrum, distal tibia, proximal humerus, proximal femur, pelvis and proximal fibula are not infrequent sites. Here we report cytologically diagnosed case of GCT distal end radius in 75 yrs male patient. We discuss its clinicopathologic features, differential diagnosis and its optimal treatment
Subdural Hematoma in Grave’s Disease Induced Thrombocytopenia.
No full textSubdural hematoma (SDH) usually occurs secondary to trauma, in bleeding disorders it may occur spontaneously. It is a rare complication of immune thrombocytopenia. Here we report a case of 45 years female presenting with presenting with complaints of headache, palpitation and menorrhagia and later diagnosed to be a case of Grave's disease with thrombocytopenia with sub dural hematoma. No such case reports are available in literature
Are abstract concepts like dinosaur feathers? Objectification as a conceptual tool: evidence from language and gesture of English and Polish native speakers
No full textStudies based on the Contemporary Theory of Metaphor (Lakoff & Johnson, 1980, 1999) usually identify conceptual metaphors by analysing linguistic expressions and creating a post hoc interpretation of the findings. This method has been questioned for a variety of reasons, including its circularity (Müller, 2008), lack of falsifiability (Vervaeke & Kennedy, 1996, 2004), and lack of predictive power (Ritchie, 2003). It has been argued that CTM requires additional constraints to improve its applicability for empirical research (Gibbs, 2011; Ritchie, 2003). This paper sets out to propose additional methodological structure to CTM, a theory of conceptual metaphor in which much of abstract thought is generated by metaphorical mapping from embodied experience (Ruiz de Mendoza Ibáñez & Pérez Hernández, 2011). Introducing Objectification Theory defined by Szwedek (2002, 2007, 2011) ameliorates a number of methodological issues in CTM. First, the embodiment claim of CTM in its current form cannot be empirically proven incorrect (Vervaeke & Kennedy, 2004) as any mapping within it is possible (although only some actually happen). Objectification introduces pre-metaphorical structure of the kind suggested by Glucksberg (2001), constraining source and target domain selection, predicting which mappings are more likely to happen. Second, while many claim that metaphors trace back to a literal concept based on embodied physical experience (Gibbs, Costa Lima, & Francozo, 2004), it is unclear what criteria are used to define „physical”. Metaphorical domains are often described using the terms „abstract” and „concrete”, Objectification proposes objective criteria for deciding whether a concept is experientially grounded. Finally, Objectification provides grounds for introducing a hierarchical framework for metaphor typology, preventing post-hoc addition of metaphor types if and when suitable for the explanation of a phenomenon; thus increasing the consistency of the CTM framework, both internally and with other cognitive science disciplines. This thesis focuses on providing evidence for Objectification Theory and identifying its applications in metaphor and gesture research
Part of Speech Tagging of Marathi Text Using Trigram Method
No full textIn this paper we present a Marathi part of speech tagger. It is a morphologically rich language. It is spoken by the native people of Maharashtra. The general approach used for development of tagger is statistical using trigram Method. The main concept of trigram is to explore the most likely POS for a token based on given information of previous two tags by calculating probabilities to determine which is the best sequence of a tag. In this paper we show the development of the tagger. Moreover we have also shown the evaluation done
Direct recordings of grid-like neuronal activity in human spatial navigation
No full textGrid cells in the entorhinal cortex appear to represent spatial location via a triangular coordinate system. Such cells, which have been identified in rats, bats and monkeys, are believed to support a wide range of spatial behaviors. Recording neuronal activity from neurosurgical patients performing a virtual-navigation task, we identified cells exhibiting grid-like spiking patterns in the human brain, suggesting that humans and simpler animals rely on homologous spatial-coding schemes
Intercoronary Continuity: A Rare Variant of Coronary Circulation
No full textCoronary circulation if significantly diseased usually develop collaterals between the distal portion of the diseased vessel and the normal artery to accomplish flow in vessel distal to the diseased segment. These collaterals can be intracoronary or intercoronary. Coronary collaterals have to be differentiated from intercoronary continuity, which is a very rare variant of coronary circulation usually seen in angiographically normal looking arteries. In our patient, although proximal left anterior descending artery revealed significant lesion but intercoronary continuity was seen between normal right coronary artery and left circumflex artery on angiography
Unusual Esophageal Twin Foreign Body (Glass Marble) in a Neonate
No full textAlthough ingestion of foreign body in oesophagus is common in pediatric age group, its occurrence in neonatal period is rare. Etiology behind these foreign bodies may be negligence or homicidal attempt for unwanted child. A high index of suspicion is required for diagnosis, whenever the neonate presents with symptoms related either to the respiratory or gastrointestinal tract. Delayed diagnosis can result in serious complications. We report a very unusual case of twin foreign body (glass marble) in oesophagus in a 30 days old female neonate. The peculiarity of this case concerns the unusual foreign body and age of the patient
Brunner Gland Hamartoma: A Rare Incidental Finding on Autopsy
No full textBrunner gland hamartoma (BGH), is a very rare benign tumor of the duodenum. It is usually asymptomatic and detected incidentally by endoscopy or other imaging modality. But, the definitive diagnosis is only by histopathological examination. We report an autopsy case in which a duodenal mass was found incidentally which was then confirmed histologically as Brunner gland hamartoma and the cause of death in this case was cerebral haemorrhage
Atypical Presentation of Mollaret’s Meningitis
No full textMollaret’s meningitis is mostly described in the setting of recurrent attacks of fever along with signs and symptoms of meningitis. It resolves spontaneously without any treatment and in most of the cases no causative organism is identified. Here we present an atypical case of mollaret’s meningitis in which the patient presented with headache and meningismus in the absence of fever
