Retractions of the tympanic membrane constitute a large proportion of ear diseases causing concern to the otologist. The clinical
features in a case of retraction pocket are varied and cholesteatoma. Also, that a retraction pocket in the posterosuperior
region and pars ftaccida is a precursor of cholesteatoma is now well recognized. We have studied 60 cases of retraction pockets
during a period of 5 years and have attempted to find out the etiology as well as the most effective treatment in such cases.
Though over the years along with a dysfunctional eustachian tube, a sclerotic mastoid has been implicated as one of the causes
of Retraction Pockets, we in our study have seen a large sized mastoid antrum (beyond 2 mm vf Lateral Semicircular Canal)
as a consistent feature in most of our cases. This was subjectively assessed as a surgical finding in tympanomastoidectomy
and objectively assessed by a high Resolution Computed Tomography of the temporal bone. We have found that a canal wall down
mastoidectomy was the most effective in preventing the recurrence of retraction pockets. In a coutry like India, canal wall
down mastoidectomy offers an acceptable solution to the problem of retraction pocket as not only is the follow up of patients
poor but also the “Second- Look” procedure is not always possible. The use of 1- 0 chromic catgut in the middle ear instead
of the more conventionally used silastic in preventing recurrent retractions can be considered as an effective single-staged
procedure. 相似文献

Postural orthostatic tachycardia syndrome(POTS) is a relatively rare syndrome recognised since 1940. It is a heterogenous condition with orthostatic intolerance due to dysautonomia and is characterised by rise in heart rate above 30 bpm from base line or to more than 120 bpm within 5-10 min of standing with or without change in blood pressure which returns to base line on resuming supine position. This condition present with various disabling symptoms such as light headedness, near syncope, fatigue, nausea, vomiting, tremor, palpitations and mental clouding, etc. However there are no identifiable signs on clinical examination and patients are often diagnosed to have anxiety disorder. The condition predominantly affects young female between the ages of 15-50 but is rarely described in older people. We describe an older patient who developed POTS which recovered over 12 mo. Recognising this condition is important as there are treatment options available to alleviate the disabling symptoms. 相似文献

While the Talairach atlas remains the most commonly used system for reporting coordinates in neuroimaging studies, the absence of an actual 3-D image of the original brain used in its construction has severely limited the ability of researchers to automatically map locations from 3-D anatomical MRI images to the atlas. Previous work in this area attempted to circumvent this problem by constructing approximate linear and piecewise-linear mappings between standard brain templates (e.g. the MNI template) and Talairach space. These methods are limited in that they can only account for differences in overall brain size and orientation but cannot correct for the actual shape differences between the MNI template and the Talairach brain. In this paper we describe our work to digitize the Talairach atlas and generate a non-linear mapping between the Talairach atlas and the MNI template that attempts to compensate for the actual differences in shape between the two, resulting in more accurate coordinate transformations. We present examples in this paper and note that the method is available freely online as a Java applet. 相似文献

This is a case report of a very rare combination of congenital aganglionosis of the intestine (Hirschsprung’s disease) and
congenital central hypoventilation syndrome-CCHS- (Ondine’s curse). The combination is also called Haddad syndrome. In about
50% of the cases of CCHS there is associated Hirschsprung’s disease. There are only about 48 cases reported worldwide. The
disease has a very high mortality especially in the settings of a developing country. 相似文献

Juvenile nasopharyngeal angiofibrama (JNA) is a benign vascular tumour which is locally aggressive and occasionally extends
intracranially. It occurs mainly in adolescent males. We report an interesting case of a targe JNA with intracranial extention
encroaching on the cavernous sinus which we treated surgically by the conventional lateral rhinotomy and transpalatal approach. 相似文献
