Recently a large-scale study on children death may occur and which generally presents with a hearing loss.

Two films at right angles This method is more applicable to the specialist as it involves a taking lateral skull view and a posteroanterior (p-a) view: possibly a p-a skull discount fluticasone online mastercard asthma treatment levels, but more commonly using a panoramic radiograph for the same purpose (Fig purchase fluticasone 100 mcg with visa asthmatic bronchitis 490. The lateral skull view shows whether the canine crown is buccal or palatal to the incisor roots discount generic fluticasone uk asthma flare, and the p-a or panoramic view shows how close it is to the mid-line. The angulation of the tooth and its vertical position are assessed using both views. The degree of displacement should be assessed horizontally, that is how close it is to the mid-line, in terms of how far it overlaps the roots of the incisors. Other radiographic signs that may suggest an abnormal path of eruption are: obvious asymmetry between the positions of the two upper canines; lack of resorption of the root of the primary canine on the affected side (Fig. If there are signs of incisor resorption, urgent advice and treatment should be sought. The image of |3 has shifted in the same direction as the tube shift:|3 is therefore nearer to the film than |1, i. Unless the upper arch is spaced, the contralateral primary canine should also be removed to prevent the upper centreline shifting. Eruption of the permanent canine should be monitored clinically and if necessary radiographically, and specialist advice sought if it fails to show reasonable improvement after a year. The main disadvantage of extracting the primary canine is losing the option of retaining it if the permanent canine fails to erupt. It may also allow forward drift of the upper buccal teeth where there is a tendency to crowding, and if space is critical a space maintainer should be fitted. Exposure and orthodontic alignment This is the treatment of choice for a well-motivated patient, provided the impaction is not too severe. The canine should lie within these limits: (1) canine crown overlapping no more than half the width of the central incisor root; (2) canine crown no higher than the apex of the adjacent incisor root; (3) canine apex in the line of the arch. The tooth can either be exposed into the mouth and the wound packed open, or a bracket attached to a gold chain can be bonded to it and the wound closed. An orthodontic appliance, usually fixed, then applies traction to bring the tooth into alignment. Exposure works well for palatally impacted canines, but buccally impacted canines usually have a poor gingival contour following exposure, even when an apically repositioned flap procedure has been used. For this reason some operators prefer to attach a chain to buccally impacted canines and to close the wound, so that the unerupted canine is brought down to erupt through attached, rather than free, gingiva. Transplantation The attraction of transplantation is that orthodontic treatment is avoided and yet the canine is brought into function. Two criteria must be met: the canine can be removed intact with a minimum of root handling; and there must be adequate space for the canine in the arch. The major cause of failure is root resorption, but the incidence of this is reduced if the surgical technique is atraumatic and the transplanted tooth is root- filled with calcium hydroxide shortly after surgery. The success rate for canine transplantation is about 70% survival at 5 years, but many clinicians regard it as being appropriate in only a few cases. Extraction of the permanent canine This is appropriate if the position of the canine puts it beyond orthodontic correction, or if the patient does not want appliance treatment. If present, the primary canine can be left in situ, and although the prognosis is unpredictable, a canine with a good root may last for many years. When it is eventually lost a prosthesis will be needed, and provision of this can be difficult if the overbite is deep⎯another factor to be taken into account when considering treatment options. Extraction of the permanent canine may also be considered where the lateral incisor and premolar are in contact, giving a good appearance. In this case it is often expedient to accept the erupted teeth and extract the canine. Leaving the unerupted canine in situ During the early teenage years there is a risk of resorption of adjacent incisor roots so that annual radiographic review is necessary, although the risk of root resorption reduces with increasing age. The onset of root resorption can be quite rapid, and for this reason many impacted canines are removed. There may be a case for retaining the canine in the short term in a younger patient, in case they have a change of heart about orthodontic treatment to align the tooth. Key Points Ectopic canines • About 2% of children have ectopic upper canines, of which 85% are palatal. Infraoccluded primary teeth (Chapter 13952H ) usually exfoliate provided that the permanent successors are present, but they should be kept under review. If they are not shed and eruption of the permanent tooth is seriously delayed, or if the infraocclusion becomes very marked, then they should be extracted and a space maintainer fitted if appropriate. Impaction of the upper first permanent molar into the distal of the upper second primary molar causing resorption (Fig. It is possible to disimpact the tooth with an appliance, but the problem usually resolves spontaneously when the primary molar is shed. The resorption may cause pain if it involves the pulp, in which case the primary molar should be removed. This allows the permanent molar to move rapidly mesially, and a space maintainer or an active appliance to move it distally should be considered (see Section 14. Second premolars in unfavourable positions are sometimes seen as incidental findings on panoramic radiographs, but fortunately they usually correct spontaneously and eventually erupt satisfactorily. Very occasionally this does not happen, and a few cases have been reported of a lower second premolar migrating towards the mandibular ramus. Upper or lower second premolars that are blocked out of the arch because of crowding usually erupt, but are displaced lingually. In terms of clinical management, supernumeraries in the upper labial segment fall into three groups: 1. Conical supernumeraries are usually close to the mid-line between the central incisors (mesiodens), and are usually one or two in number. They are sometimes inverted, and their positions can range from having erupted to lying above the incisor apices. The majority do not prevent eruption of incisors, but may cause some displacement or a median diastema, in which case they should be extracted (Fig. They should also be extracted if they erupt or if the adjacent incisors are to be moved orthodontically. Tuberculate supernumeraries are the main cause of failure of eruption of upper permanent incisors (Fig. A central incisor which fails to erupt before the adjacent lateral incisor should be radiographed, and any supernumerary teeth localized (see Section 14. These should be removed surgically as soon as possible, and it is essential that the space is maintained or, if already lost, re-opened with an appliance. About 75% of unerupted incisors erupt spontaneously within 2 years of removal of supernumeraries, so it is worth waiting for at least 18 months before considering surgical exposure.

First order fluticasone 250 mcg asthma 2014 soundtrack, diseases are no longer regarded as concrete effects of deliberate divine dispensation or as god- sent pollutions; second buy fluticasone once a day difficult asthma definition, for the treatment of the disease an appeal to the healing power of the gods (as made in temple medicine) is unnecessary or even useless generic fluticasone 500 mcg without prescription asthmatic bronchitis que, since the cure of the disease can be accomplished by ordinary natural means. Both implications seem to obtain for the writer of On the Sacred Disease, for he explicitly denies the diseases are god-sent in the traditional sense (1. In this way his positive theological statements might be viewed as providing the general philosophical framework on which his aetiological and therapeutic views are based. On the Sacred Disease 61 However, this extrapolation of a ‘theology’ from the statements about the divine character of the disease presupposes three generalisations which are in themselves questionable, and which appear to be inconsistent with other assertions in the treatise. First, it is ignored that there is a difference between calling a particular phenomenon ‘divine’ in virtue of a certain aspect or characteristic, and speaking about ‘the divine’ (to theion)ina general and abstract way. As a result, it is tacitly assumed that by defining the divine character of the disease as its being caused by natural factors (or as its having a nature) the author implicitly confines the range of the divine to nature or to the regularity which natural phenomena show (as if he not only said ‘Nature is divine’, but also ‘The divine is identical with nature’). Not only is such a generalisation of the use of the word theios dangerous in itself, but it also lacks any textual justification, for in none of the ‘positive’ statements does the writer use the expression to theion in an abstract way. This need not imply that all other phenomena are divine in this new sense of ‘being natural’ ( panta, ‘all’, in 18. The author leaves open the possibility that there are other things which may be the effect of divine dispensation (in the traditional sense), for example divine blessings, and the idea of divine dispensation or intervention as such is nowhere rejected. We may even wonder whether the author really rejects every appeal to divine healing, for in spite of his self-assurance concerning the curability of the disease (18. It may be doubted whether the author would regard an appeal to the gods in such cases as useless. Admittedly, one of his concerns is that epilepsy should be treated no differently from any other disease; but he nowhere categorically rejects any appeal to the gods for the healing of hopeless cases. These remarks may seem speculative and ill-founded, but I will qualify this issue below. Thirdly, it is supposed that the word phusis is used here in the sense of ‘Nature’ or even ‘the laws of Nature’, or in any case of something general and universal, an all-pervading principle, comparable to the use of phusis in Presocratic philosophy, for example in treatises entitled ‘On Nature’ ( peri phuseos¯ ). But in the text of On the Sacred Disease the word phusis is used almost exclusively to denote the specific nature or character of the disease (18. Apart from the question whether these generalisations are justified, there is evidence from the text itself that it is wrong to attribute such a ‘naturalistic’ theology to the author of On the Sacred Disease. In the polemical first chapter of the treatise, in his objections against the ideas and the practices of the magicians, we can find several implicit presuppositions which do not make sense within such a naturalistic conception of the divine. This applies particularly to the accusations of impiety (asebeia) and atheism (atheos) which begin in 1. First, the writer criticises his opponents for making impious claims, for example that they can influence the movements of sun and moon and the weather. This claim, the author says, amounts to believing that the gods neither exist nor have any power, and that what is said to be divine actually becomes human, since on this claim the power of the divine ‘is overcome and has been enslaved’ (1. I do not mean to say that we may infer from this that the author of On the Sacred Disease believes the movements of the sun and the moon and the weather-phenomena to be manifestations of divine agency (cf. On the Sacred Disease 63 contrarily to their own principles: they pretend to be pious men and to rely on the gods for help, but in fact they make the impious claim to perform actions which a pious man believes to be reserved to the gods alone. Yet the author himself appears to have an explicit opinion on what is pious and what is not (or what a truly pious man should and should not do). The impiety of his opponents, he points out, consists in their practising purificatory rites and incantations, and in their cleansing the diseased by means of blood as if they had a ‘pollution’ (miasma)orwere possessed by a demon, or bewitched by other people. Yet instead of this they practise purifications and conceal the polluted material lest anyone would get into contact with it. Now, this is not to suggest that the author of On the Sacred Disease, who has always been hailed as one of the first champions of an emancipated science of medicine, actually was a physician serving in the cult of Asclepius46 – even though the borderlines between secular 43 See Nestle (1938) 2; Edelstein (1967a) 223, 237. The reason for not accepting this suggestion is simply that the text does not support it (on 1. Yet what it does show is that the author has definite ideas on what one should do when invoking the help of the gods for the healing of a disease, and he may very well be thinking of the particular situation of temple medicine, with which he was no doubt famil- iar (which does not, of course, imply that he was involved in these practices or approved). One may point to this hypothetical ‘should’ and object, as I suggested at the beginning of this chapter, that these remarks need not imply the author’s personal involvement, but are solely used as arguments ad hominem. He may, for the purpose of criticising and discrediting his opponents, point out how a man ought to act when making an appeal to divine help for the cure of a disease, but this need not imply that he himself takes this way of healing seriously (after all, invoking the gods for healing presupposes the belief in a ‘supernatural’ intervention in natural processes). In this way one might say that all the preceding stipulations about impiety and piety are just made for the sake of argument and do not reveal any of the author’s own religious convictions: he may be perfectly aware of the truly pious thing to do without being himself a pious man. On the Sacred Disease 65 But I hold that the body of a man is not polluted by a god, that which is most corruptible by that which is most holy, but that even when it happens to be polluted oraffectedbysomethingelse,itismorelikelytobecleansedfromthisbythegodand sanctified than to be polluted by him. Concerning the greatest and most impious of our transgressions it is the divine which purifies and sanctifies us and washes them away from us; and we ourselves mark the boundaries of the sanctuaries and the precincts of the gods, lest anyone who is not pure would transgress them, and when we enter the temple we sprinkle ourselves, not as polluting ourselves thereby, but in order to be cleansed from an earlier pollution we might have contracted. It seems that if we are looking for the writer’s religious convictions we may find them here. The first sentence shows that the author rejects the presuppositions of his opponents, namely that a god is the cause of a disease; on the contrary, he says, it is more likely that if a man is polluted by something else (™teron, i. There is no reason to doubt the author’s sincerity here: the belief that a god should pollute a man with a disease is obviously blasphemous to him; and the point of the apposition ‘that which is most corruptible by that which is most holy’ (t¼ –pikhr»taton Ëp¼ toÓ ‰gnot†tou) is clearly that no ‘pollution’ (miasma) can come from such a holy and pure being as a god. As for the positive part of the statement, that a god is more likely to cleanse people of their pollutions than to bestow these to them, one may still doubt whether this is just hypothetical (‘more likely’) or whether the author takes this as applying to a real situation. This sentence shows that the author believes in the purifying and cleansing working of the divine. I do not think that the shift of ‘the god’ (¾ qe»v) to ‘the divine’ (t¼ qe±on) is significant here as expressing a reluctance to believe in ‘personal’ or concrete gods, for in the course of the sentence he uses the expression ‘the gods’ (to±si qeo±si). In fact, this whole sentence breathes an unmistakably polemical atmosphere: the marking off of sacred places for the worship of the gods was 48 But ‹n kaqa©resqai represents a potential optative rather than an unfulfilled condition. The distribution of ¾ qe»v, o¬ qeo© and t¼ qe±on in this context does not admit of being used as proof that the author does not believe in ‘personal’ gods. The use of the word ‘sprinkle’ (perirrain»meqa), which means ritual cleansing with water,50 is opposed to the ‘impious’ use of blood in the purificatory rituals of the magicians (1. Does this mean that he believes, after all, in the divine healing of diseases as taking place in temple medicine? One cannot be sure here, for the divine purification is explicitly defined by the author as applying to moral trangressions (tän ‰marthm†twn), indeed to the greatest of these. This restriction is significant in that it may indicate that in the author’s opinion an appeal to divine cleansing is only (or pri- marily) appropriate in cases of moral transgressions. I would suggest, as a hypothesis, that the author of On the Sacred Disease here aims at marking off the vague boundaries between medicine and religion: in his opinion it 50 See Parker (1983) 19; Ginouves (` 1962) 299–310. At any rate, the phrase oÉc Þv miain»menoi obviously expresses a reaction against the admittedly strange idea that the sprinkling of water entails pollution (on the prohibition to take baths see Ginouves (` 1962) 395 n.
