The Battle Of Brandywine essays The Battle of Brandywine: Part 1 of 10 The British... Many of the 15,000 British troops spent the night in Kennett Square population 2,000 unwinding and carousing, while a battle General Howe's flanking strategy was devised two days earlier: While General Knyphausen attacked at Chadd's Ford, as Washington expected, Cornwallis would stealthily move north, cross the Brandywine, and flank Washington's right. [Map and a fuller The Americans... By the night of September 10th, the American troops were extended along a six-mile line covering the east side of the Brandywine Creek. Washington knew that the British army would have to ford the Brandywine if they were to get to their target Philadelphia. He discounted the possibility of being flanked, assuming that Howe would rely upon his his greater troop strength and superior artillery to press a direct attack. Washington believed that the British would have to ford the ...

Polybius, the Constitution of the Roman republic Essay

Polybius, the Constitution of the Roman republic - Essay Example Polybius begins the analysis of separate magistrates with consuls. The consuls, when they are present in Rome, govern all the people and all the officers except the tribunes, they report to the Senate on all matters and enter the embassy to the Senate, oversee the execution of enactments, summon the national assembly, make proposals, execute orders, have unlimited authority in military affairs, may punish any person in the military camp and spend public funds at their discretion. The senate primarily administers the state treasury; in its jurisdiction are all crimes committed in Italy, it is responsible for the administration of embassies in countries outside of Italy; it decides issues of war and peace, receives the embassy. Polybius emphasizes that people do not participate at all in these events. Realizing that may give the impression that people can do nothing substantial, the author hastens to warn that this is a false opinion. He draws the reader’s attention to the fact that people have a very strong influence on the life of the Roman state, as in people’s hands is the right to reward and punish. From the viewpoint of Polybius these incentives determine people’s entire lives.

Is a college education worth the time and money Essay

Is a college education worth the time and money - Essay Example The experience gained from this type of learning addresses every dimension of the total individual. Firstly, a college education attends to the spiritual dimension of the individual for it is at this juncture that an individual comes face to face with his/her inner self. One is forced to brutally confront oneself and acknowledge one’s strengths, weaknesses and even failures as one has to learn to cope with meeting deadlines, completing a plethora of assignments and making presentations that may be harshly criticized. In addition, it is because of this great demand of external output that the student must turn to his/her inner being and decide whether to maintain the morale values which may have been embedded from early childhood or whether to abandon them and give in to self. This opportunity to interact with one’s inner self in a real way certainly compensates for any time or money that may have been spent to attain it. Secondly, college education positively affects one’s social being. The student has the opportunity to meet with others of his/her age and experience the type of fellowship that is borne out of sharing pains and joys, sufferings, successes and failures. The network that is formed here can only add value to the student’s life for it may be the means through which the student meets persons that may assist in future job hunting or promotions. What is more, students gain the required skills, knowledge and attitudes needed to obtain a good paying job which enhances the opportunity for them to receive promotion at their job. Mathews in his 2007 article on Multiplying Benefits of College for Everybody gave a fine example of the latitude which is granted by the college graduate. He states, â€Å"If a Hamilton College graduate with a degree in English literature decides she would prefer to become a fry cook or a midwife or a farmer, she can develop those skills relatively quickly as

Ophthalmoplegic Migraine Paediatric Oculomotor Schwannoma

Ophthalmoplegic Migraine Paediatric Oculomotor Schwannoma Corresponding Author: Dr.R.Subasree Title : Ophthalmoplegic Migraine and Paediatric Oculomotor Schwannoma: Cause or Co-Incidence? Structured Abstract: Objective: To report a case of Ophthalmoplegic migraine with Pediatric Oculomotor Schwannoma which is very rare. Methods: A 16 year old boy admitted as inpatient at our tertiary referral centre and University hospital in South India, with history of recurrent headaches and oculomotor palsy of 14 years duration was evaluated in detail to rule out posterior fossa, orbital fissure, parasellar lesions, granulomatous disorders and aneurysms. Results: Initial CT Brain revealed a nodular non-enhancing lesion in the interpeduncular cistern, MR Imaging along with CISS 3D sequence done two years later after CT, revealed a small enhancing nodular lesion at the level of midbrain in the interpeduncular cistern at nerve exit level suggestive of schwannoma of third nerve. Practice: Patient was treated with analgesics, nimodipine and valproate with which there was a partial response. During his subsequent 2 year follow-up, his frequency and severity of attacks had reduced. Conclusion: Oculomotor nerve schwannomas are extremely rare. Only 12 children under the age of 18, without neurofibromatosis have been sufficiently documented. The coexistence of OM and Oculomotor schwannoma suggests that it is not a coincidence. Awareness and suspicion is required to identify cranial cephalalgia /OM and it warrants thorough investigation to rule out intrinsic lesions mimicking OM. Implications. Controversies exist till date regarding etiology, pathophysiology, imaging findings and management guidelines of OM. The rare association reported in our report gives insight into better understanding of the pathophysiology and clinico-radiological correlations in OM. Keywords: Ophthalmoplegic migraine, Oculomotor Schwanomma Introduction Ophthalmoplegic migraine is very rare with annual incidence being 0.7 per million. It most often occurs in infancy or childhood. There are recurrent attacks of headache in association with ophthalmoplegia due to paresis of cranial nerve III, IV, or VI .The episodes of ophthalmoplegia may persist for several hours to several weeks, months, or permanently. Most often it is self-limited condition. Ophthalmoplegic migraine is also recognized as a cranial neuralgia according to 2004 edition of the International Classification of Headache Disorders. [1] .Paediatric Oculomotor Schwannoma is extremely rare and it can mimic OM. We describe a young boy with recurrent ophthalmoplegic migraine and oculomotor schwannoma in MR imaging. Clinical Observation A 16 year old boy presented with history of left hemicranial headache of 14year duration. The headache was throbbing, severe associated with drooping of left eye, blurring of left eye vision, photo-phonophobia, nausea and vomiting. The frequency of attacks was around 15 per month each lasting for 3-48 hours. During the attack, he was found to have left sided ptosis, poorly responsive normal sized pupil and mild left elevation and adduction restriction. (Figure 1).There was persistent residual vision loss in left eye with acuity of 6/60. Fundus was normal. There were no other deficits. Investigations were carried out to rule out posterior fossa, orbital fissure and parasellar lesions. Initial CT Brain revealed a nodular non-enhancing lesion in the interpeduncular cistern , MR Imaging along with CISS 3D sequence done two years later (Figure 3a, 3b) revealed a small enhancing nodular lesion at the level of midbrain in the interpeduncular cistern at nerve exit level suggestive of schwannoma of third nerve. MR Angiography was normal. (Figure 3c). Patient was treated with analgesics, nimodipine and valproate with which there was a partial response. Steroids were not administered. During his subsequent 2 year follow-up, his frequency and severity of attacks had reduced. Paediatric Oculomotor Schwanomma is present as painless oculomotor deficit or may be asymptomatic and detected incidentally. Its presence with OM poses a question whether it was a mere coincidence or the cause of OM. Discussion: Ophthalmoplegic migraine is a rare distinct neurologic syndrome characterized by recurrent headache and ophthalmoplegia. The third cranial nerve is most commonly affected. Most patients recover completely within days to weeks, but a minority are left with persistent neurologic deficits. [1] .As per the International Classification of Headache, ophthalmoplegic migraine is defined as at least 2 attacks of ‘‘migraine-like’’ headache followed within 4 days by paresis of the third, fourth, and/or sixth cranial nerves, including ophthalmoparesis, ptosis, or mydriasis .[2] Gap between the onset of headache and the cranial nerve palsy has varied between 2 days and10 weeks. [3]The exact aetiology of this condition remains unknown. Oculomotor nerve compression, ischemia, swelling of the posterior cerebral artery, pituitary swelling, vascular anomaly, benign viral infection, demyelinating neuropathy, activation of trigemino-vascular system are the various pathogenesis implicated. Diseases such as vascular malformation, granulomatous infections, pituitary apoplexy, sarcoidosis and chronic inflammatory, demyelinating polyneuropathies may have similar clinical presentation like OM. So contrast enhanced MRI and magnetic resonance angiography should be the investigations of first choice for the diagnosis of OM, followed by a careful clinical examination and spinal tap. Sometimes, conventional angiogram may be necessary to exclude an aneurysm. [4]. Mark et al. 1998.,[5]found focal thickening of the nerve in non-contrast studies, and further thickening was present on the contrast-enhanced images in the area of the exit zone of the nerve in the inter peduncular cistern. Carlow studied the magnetic resonance scans in six patients diagnosed with OM and did a retrospective literature survey in 17 patients with OM, all of whom showed thickened ipsilateral oculomotor nerves at the midbrain exit in noncontrast T 1 -weighted images. Contrast T 1 -weighted magnetic resonance scans showed enhancement of the ipsilateral oculomotor nerves. [6].Many cases show improvement in the enhancement of cranial nerve III with resolution of the symptoms, but the timing and degree of resolution has not been consistent in reports. Contrast enhancement on MRI is not a sine qua non for the diagnosis of OM. Gelfand AA et al., 2011 [1] systematically reviewed all cases of OM in literature between1995 to 2010. There were a total of 80 cases .The median age at the time of the first ophthalmoplegic migraine attack was 8 years (3-16 years) .The third cranial nerve was involved in the vast majority of cases (83%), sixth cranial nerve was involved in 20% and the fourth nerve in 2% of cases. The interval between headache onset and ophthalmoparesis ranged from immediate to up to 14 days. The ophthalmoplegia tended to last longer (2 to 3 weeks to 2 to 3 months) .In 54%, persistent deficits were observed. Of 52 patients who had a contrast brain MRI during an acute attack, 75% had contrast enhancement of the third nerve and 76% had nerve thickening. There was a benefit from corticosteroid treatment in 54%. Schwannomas are benign peripheral nerve sheath tumours with great propensity to arise from vestibular nerves. Oculomotor nerve schwannomas are extremely rare. There are only 40 cases reported in the literature. Only 12 children under the age of 18, without neurofibromatosis have been sufficiently documented. [7] In 1982, Leunda et al. [8] reported a case in an 11-year-old boy whose tumour was resected en bloc and ranked as the largest oculomotor nerve schwannoma documented at that time, with a 55-mm diameter. Since then, another 11 histologically proven paediatric cases have been described successively in the literature. The average diameters of the paediatric tumours size is 19.5 mm. Oculomotor nerve paresis was the most common neurological sign and a variable degree of oculomotor nerve dysfunction, including ptosis, diplopia, or dilated pupil, was present in all but one . Duration of preoperative symptoms and signs ranged from 2 weeks to 12 years. Authors opine that lesion size did not correlate with the degree of oculomotor nerve deficit. Ipsilateral ophthalmoplegic migraine was found in two cases of cisternal microlesions involving the initial prepontine segment of oculomotor nerve. [7].Total removal of schwannoma usually resulted in severe postoperative parent nerve paresis. Surgical tr eatment was indicated only for large tumours that presented in association with consciousness disturbance, other cranial nerve signs, or hemiparesis due to mass effect, or in cases where the lesion showed malignant features with rapid enlargement. Murakami et al., 2005 [9] described a case of an 11-year-old girl with oculomotor nerve schwannoma who had been suffering from symptoms mimicking OM. Her attacks became more frequent and were not controlled by medication. After surgery, the frequency of OM attacks reduced. This was the first report to describe a pathologically confirmed case of oculomotor nerve schwannoma mimicking OM. Riahi A et al., 2014[10] described a 12 year old girl with recurrent painful ophthalmoplegia, who on examination was found to have left oculomotor palsy. Her third MRI focusing on third nerve revealed schwannoma of the oculomotor nerve in left cisternal portion. Kawasaki et al., 1999 [11] reported a case of the coexistence of OM and ipsilateral 3rd nerve schwannoma .The authors had an acute and a follow-up MRI during a recovery phase and noticed no difference. The coexistence of two rare conditions suggests that a mere coincidence is unlikely. It has been proposed that repeated inflammation could lead to a demyelination/ remyelination process with Schwann cell proliferation and onion bulb formation. There are no published treatment trials for ophthalmoplegic migraine. Oral steroids may be of possible benefit in treating acute exacerbations based on available case series. Prompt steroid therapy at the time of attack might minimize permanent sequelae of OM, including residual weakness of the third cranial nerve and pupillary dysfunction. Bharucha et al., 2007 [4] state that various treatments have been described, including steroids acutely and flunarizine, acetazolamide, propranolol, cyproheptadine, or verapamil prophylactically. OM is a heterogeneous disorder that needs adequate scrutiny, periodic magnetic resonance monitoring, and clinical correlation before we can conclude and draw management guidelines. Conclusion: Awareness and suspicion is required to identify cranial cephalalgia /OM as it is a rare entity and diagnosis even by headache experts is made by exclusion. It warrants thorough investigation to rule out intrinsic lesions mimicking OM. The rare association reported in our report gives insight into pathophysiology and clinico-radiological correlations in OM. Bibliography 1. Gelfand AA, Gelfand JM, Prabakhar P et al.

Nietzsches Critique of Religion Essay -- Nietzsches Critique of Chri

Nietzsche's critique of religion is largely based on his critique of Christianity. Nietzsche says that in modern Europe, people are atheistic, even though they don't realise it. People who say they are religious aren't really and those who say they have moved on haven't actually moved on. Certain people in society retain features of Christianity. For example, socialists still believe in equality in all people. Others still have pity for the poor and needy etc. Nietzsche dislikes religion especially Christianity because it encourages and promotes slave morality. Nietzsche says that we should be striving towards master morality, but Christianity has the completely opposite values to those of the master morality. For example, religion wants us to be like slaves and give things up instead of trying to be great. He talks about a slave revolt in morality, which leads to the dominance of slave values over master values. Christianity is that slave revolt. The problem for Nietzsche is the New Testament - the introduction of Jesus. He thinks that linking the Old Testament with the New Testament is very cheeky. They are two different books with complete different ideas and so should not be linked together. The Old Testament is full of power - Nietzsche likes that. But he objects to the values of the New Testament that shouldn't be linked to the Old Testament. They demote power. He sees religion as intensely nihilistic - it's all about denying life and being negative. Nietzsche feels that the New Testament is also like that. We have to go beyond this. If Christianity and Schopenhaur are based on denying life ... ...itique is that he views religion from the outside, so doesn't this make it a one-sided story? But obviously Nietzsche will think that his critique is one-sided. He is a perspectivist. Why is a view from outside any less valid than a view from inside? Is the ladder of religious cruelty a complete account of religious development. What about a sacrificing himself for humanity? This doesn't get mentioned. However we could say that Nietzsche rejects that because he obviously doesn't believe in God and insofar as God is 'one of the suffering'. This confirms Nietzsche's negative view of religion / Christianism. Nietzsche said that religion shouldn't How can religion not be an 'end-in-itself' for religious believers? A counter-argument to this would be to say that religion as an instrument is not a religion.
