The results were classified into those who iden- tified with the Deaf community, those who identified primarily with the Hearing World (including hearing and some deaf par- ticipants), and those who identified with both communities. Attitudes towards genetic testing The data showed that 23% participants who identified more for deafness from deaf people and with Deaf community were interested in prenatal diagnosis for deafness, compared to 47% of participants who identified more their families with the hearing world.

This shows that Deaf cultural solidarity that some Deaf people have, and also deafness is not a condition that is clearly detrimental.

Audiometrically, there are normal bone-conduction thresholds ( 20dB) and an air-bone gap 15dB averaged over 0. Commonly, the hearing threshold is measured at frequen- cies separated by octave intervals, from 0. Indeed, as the hearing thresholds and auditory threshold values of contiguous frequencies are correlated, the more the frequencies recorded, the less the probability of damage the errors associated with a single-frequency threshold mea- surement.

In practice, the lesions with this pathology, about 80% show a hearing impairment, usually involve both the outer and the inner hair cells, with the although the amount of hearing loss correlates only poorly with proportions depending on the causative factor.

There are, however, mal in its microscopic structure, but the biochemical–metabolic many exceptions to this picture. In fact, the hearing may be variously compromised in relation to the complex effects result- ing from tumour growth: for instance, demyelinisation (9),. The most popular, based on an 90 - 100- adaptive procedure, is known as Békésy audiometry. This tech- 110- nique requires the subject to control the stimulus intensity 120- according to his responses. This common threshold configuration may approximately suggest the type and distribution of the lesion within the cochlea: at the basal end (high frequencies), probable involvement of both outer and inner hair cells; at the apex (low frequencies), probable involvement of half of the population of outer hair cells. However, the thresholds recorded in response to low frequency and very intense tones could be due to vibrotactile perception. Type I (overlapping of thresholds for continuous and interrupted stimuli) is observable in normal hearing and conductive hearing loss. Type V, not shown here, display a threshold change in interrupted tones worse than that for continuous tones; it is associated with nonorganic hearing loss. Understanding the phenotype: basic concepts in audiology 23 The subject’s task consists of pressing a button when he audioscan perceives the signal and releasing it when he hears nothing. Finally, the instrument produces graphic trac- ings of the up–down intensity excursions around the threshold.

Békésy audiometry, however, may 40 son be recommended in selected cases when more precision is 50 needed in estimating the hearing threshold. Indeed, threshold (B) values obtained with automated audiometry are more sensitive, on average, than those obtained with classical audiometry, and Figure 2. The two audiograms have of absolute sensitivity or the test–retest variability have been been obtained from a mother and son, both healthy carriers (on classical obtained by an interrupted stimulus of 500 ms duration, 50% audiometry) of a genetic hearing loss.

Since many frequencies can be tested other than those record- Estimating a progressive hearing able by classical audiometry, the threshold profile often exhibits characteristic “notches,” indicating some frequency-related impairment discontinuities of the hearing acuity.

Androgen excess in women leads to increased hair growth in most androgen-sensitive sites order 10mg nolvadex. In the scalp generic 20 mg nolvadex fast delivery, however, hair loss occurs because andro- gens cause the hair to spend less time in the growth phase. Male-pattern balding may cause stress but is primarily caused by high androgen levels. Androgen levels are equally distributed throughout the body; it is the local environment that dictates the end-organ effect. Sun-exposed areas, such as the face and arms, are as androgen-sensitive as non- exposed areas. A vesicular lesion with an inflammatory base is char- acteristic of herpes simplex. Scabies lesions are frequently found in interdigital web spaces and usually consist of inflamma- tory papules. Contact dermatitis usually resolves with removal of the offending agent or with barrier protection (e. Adjunctive therapies include high-potency topical steroids while the dermatitis runs its course. For patients who fail topical steroids, systemic therapy with oral prednisone will usually suffice. Hydroxyzine, an oral antihistamine, is useful when pruritus is a predominant com- plaint or when the lesion is thought to be due to scratching or rubbing, as in lichen simplex chronicus. Topical retinoic acid is an irritant and will worsen the skin inflammation and discomfort. The lesion is also commonly found on the extremities, face, and in the oral cavity. The cutaneous embolic or im- munologic manifestations of bacterial endocarditis are smaller and typically found in the extremities. Hepatitis C infection may cause skin lesions due to cryoglobulinemia; however, these appear as vasculitic lesions typically on the lower extremities. This patient has rapidly progressive virilization and concern should be present for a virilizing tumor. Laser therapy will be effective at removing the hair, but the long-term effects are yet to be determined. The lesions are variably pruritic and may either improve or worsen with sunlight exposure. On the face, the most common locations are the eyebrows, eye- lids, glabella, and nasolabial folds. Lesions typically worsen in the winter, and emotional stress also seems to exacerbate the rash. The pathogenesis remains unclear but the yeast Malassezia furfur appears to play a role. Successful treatment with top- ical ketoconazole and the prevalence of the disease in immunocompromised patients sug- gests that the yeast is pathogenic. Patients with dermatomyositis may exhibit a heliotrope rash (violaceous rash around the eyelids) and may complain of proximal muscle weakness. Treatment consists of repeated phlebotomy to diminish excessive hepatic iron stores. This is not an autoimmune process where glucocorticoids would potentially be of benefit. Lupus and sarcoid can both present with facial rashes; however, the periorbital involvement seen here is more associated with dermatomyositis. Rheumatoid arthritis and scleroderma are not distinctly associated with facial rashes. It is characterized by erythematous, sharply demarcated papules and rounded plaques covered by a silvery scale. Fingernail lesions such as pitting, onycholysis, or nail thickening or subungual hy- perkeratosis are present in 50% of patients. Topical treatment options for psoriasis include mid-potency glucocorticoids, vitamin D analogues, retinoids, and ultraviolet light. Oral glucocorticoids should not be used for the treatment of psoriasis due to the life-threatening risk of devel- oping pustular psoriasis when therapy is discontinued. They typically begin on the trunk and consist of symmetric macules and pap- ules that may become confluent. In contrast to Stevens-Johnson syndrome and toxic shock syndrome, involvement of the mucus mem- branes is uncommon. The rash usually develops within 1 week of initiation of therapy and resolves with discontinuation. The most common drugs that cause morbilliform eruptions in- clude penicillin derivatives, allopurinol, sulfonamides, and nonsteroidal anti-inflamma- tories. Pemphigus is an autoimmune bullous disease of the skin and mucus membranes that is rarely associated with drugs such as penicillin. Biopsy of this lesion would show neutrophil-rich infil- trates in the dermal papillae. There is no associ- ation with carpal tunnel syndrome or type 1 diabetes mellitus. Tinea pedis is commonly associated with tinea manuum, unguium, or cruris (dermato- phytosis of the hands, nails, or groin, respectively). Candidal onychomy- cosis usually occurs only in the immunocompromised host or with chronic mucocutane- ous candidiasis. The lesions are usually erythematous papules or plaques with a thick scale that occludes hair follicles. If that is ineffective, systemic therapy with an aminoquinoline antimalarial may be indicated. Systemic glucocorticoids or immunosuppressives are not indicated for local- ized disease. Although malignant melanoma may take on myriad appearances, the loca- tion, progress, and description of this lesion is more suggestive of discoid lupus, therefore, surgical excision and lymph node dissection are not indicated at this time. Multiple primary lesions, regional adenopathy, and secondary bacterial infection are variably present. Leishmania parasites are transmitted by the bite of the female phlebotomine sandfly. While probing for a blood meal, sandflies regurgitate the parasite’s flagellated promasti- gote stage into the host’s skin, which eventually get phagocytized by macrophages. The larvae of Trichinella spiralis are found in undercooked pork and game meat and cause the syndrome of trichonosis. Inhalation of the spores of Bacillus anthracis causes the pulmo- nary form of anthrax infection. The tsetse fly is the vector for the trypanosome parasite, which can cause sleeping sickness. Mosquito bites transmit a number of infections, most notably malaria and a variety of viral infections such as viral encephalitis. With terbinafine therapy, there is also a risk of drug-drug interaction with drugs that require the P450 enzyme for metabolism. Most treatment courses require se- rial monitoring of liver enzymes to avoid drug-induced hepatitis or liver failure.

Much has been written about the reasons for this scientific attitude; in this respect it should be noted that systematic attempts at falsifying theories by gathering counter-examples in empirical reality were the exception rather than the rule in antiquity order nolvadex with a visa. For this reason the encephalocentric view on the location of the mind needed quite some scientific and rhetorical force to secure its position in the debate purchase nolvadex 10 mg visa. However buy nolvadex cheap online, it is unlikely that the form in which this collection has come down to us dates back to Aristotle best order nolvadex. Jackson (1986) 31–3; Klibansky, Panowsky and Saxl (1964) 15–40 [and (1990) 55–91]; Muri (¨ 1953) 21–38; Pigeaud (1978) 23–31; Pigeaud (1981a) 122–38; Pigeaud (1984) 501–10; Pigeaud (1988a); Simon (1978) 228–37; Tellenbach (1961) 1–15 [and Rutten (¨ 1992); Roussel (1988)]. Significantly, these writings do refer to the so-called constitutional type of ‘the melancholic’ (ho melancholikos), yet without providing clarity on the underlying physiological theory, and in any case it is nowhere related to a bodily fluid called ‘black bile’. The problem is that, on the one hand, this step was sup- posedly first made in Aristotle’s school (according to Jouanna (1975) 296), whereas on the other hand the Aristotelian use of ‘the melancholics’ as an established term seems to suggest that this step had already been taken. I say ‘seems’, for it is by no means certain that Aristotle actually associated the term ho melancholikos with this ‘constitutional type’ and its affiliated theory of the four humours. Aristotle on melancholy 141 seems to mean virtually the same as manikos (‘mad’) or mainesthai (‘be mad’). This first of all requires an analysis of all occurrences of the words melancholikos and melaina chole¯(sections 2 and 3) and an analysis of the role Aristotle assigns to (black) bile in human physiology (section 4). The results will enable us to gain a better insight into the relationship be- tween Aristotle and the Hippocratic theory of humours. In the second part of this chapter (sections 5–7) I will discuss the theory set out in Pr. This will also reveal the philosophical significance of the issue of melancholy: for Aristotle seems to use melan- cholics to illustrate the role played by the human phusis, both in the sense of ‘natural predisposition’ and of ‘physiological constitution’, in the moral, sensitive and intellectual behaviour of man, namely what the Problemata text calls the ‘character-affecting aspect’ (to ethopoion¯ )ofphusis. Proof of this is that certain people are disturbed by the fact that if they are unable to recollect something, despite making a strong effort, the process of recollecting continues even after they stop making the effort. The cause of this disorder is that just as someone who throws something is unable to bring the thrown object to a halt, the process of recollection causes a bodily 12 Muri (¨ 1953) 34; Flashar (1966) 37–8; Klibansky et al. For the historical background to this use of the term, as well as the origin of the notion ‘black bile’, see also Kudlien (1967a) 75–88 and (1973) 53–8. The subject of parenocle±n is ˆn†mnhsiv (this refers to the p†qov mentioned in line 25); oÅd•n ¨tton belongs to ˆnamimnhskesqai. The ‘disturbance’ (parenocle±n) does not so much consist in the fact that these people are unable to remember something in particular (for how could this be an indication that memory is a physiological process? The disorder manifests itself particularly in people whose region of sensory perception is surrounded by moisture, ‘for once moisture is set in motion, it does not readily stop moving until the sought object is found and the movement has taken a straight course’. Melancholics are mentioned here in the context of a discussion of the bodily (physiological) aspect of recollection. Their characteristic feature is their disorder14 in the process of recollection, in that they are unable to con- trol this process. As causes for the disorder Aristotle first mentions the special movement by images (phantasmata) and secondly moisture (hugrotes¯ ) lo- cated around the aisthetikos topos¯ , the heart. Although it remains uncertain whether this sentence refers to melancholics, the structure of the argument seems to indicate that this moisture is the physiological cause of the previ- ously mentioned special affection by images. In 457 a 25 he discusses people with prominent blood vessels who, as a result of this width of their vessels (poroi), are not much given to sleep. Aristotle subsequently18 states that melancholics are not prone to sleep (hupnotikoi¯ ) either, for their inner parts are chilled, which results in limited ‘evaporation’ of food (according to Aristotle, this ‘evaporation’, anathumiasis, is the cause of sleep). This is also the reason why melancholics are on the one hand good eaters, yet on the other hand they are spare; their 14 On (par)enocle±n see On Divination in Sleep (De divinatione per somnum, Div. With regard to the complication that in Greek medicine melancholics were usually associated with dryness, I endorse Sorabji’s solution (1972a, 113): black bile is of course a liquid (cf. In this passage melancholics are not characterised by the fact that they are particularly moist but by the fact that there is moisture around their heart (as is occasionally the case with other people), namely black bile. For the tendency in this chapter of the Problemata to take certain features, which Aristotle occasionally mentions in relation to melancholy, as part of a more fundamental basis of the melancholic nature, see n. Aristotle on melancholy 143 body is in such a condition (diakeitai) that it seems as if they have not had any food at all:19 ‘for black bile is cold by nature and therefore chills the nutritive region (threptikos topos) of the body as well as any other parts that may contain this residue’. First of all, it should be noted that Aristotle speaks not only of melancholics but also of ‘black bile’ (melaina chole¯): underlying his use of the term hoi melancholikoi is a physiological concept that recognises black bile as a distinct fluid (i. The text implies that black bile is cold by nature and has a chilling effect on its environment. Cold as a natural elementary quality of black bile corresponds to the Hippocratic characterisation of black bile as dry and cold (see Flashar (1966) 39), although the phrase ‘naturally’ seems to leave open the possibility of heating. At first there seems to be considerable discrepancy between the two writings: whilst melancholics are presented as an example of people with clear and prophetic dreams in On Divination in Sleep (Div. Closer analysis of the relevant passages should reveal whether they are indeed inconsistent. To start with the passages in On Divination in Sleep, at the beginning of chapter 2 (463 b 12ff. For this reason dreams are not divine, albeit beyond human control, for nature is beyond human control 19 See Pr. The only explanation for this is that these dreams are not sent by a god, but it is in the nature (phusis) of garrulous and melancholic people to see all kinds of images (in their dreams), as these people are subject to a large number and variety of movements, which cause them to chance upon ‘images similar to events’ (omo©oiv qewržmasin). Their good fortune in this respect can be compared to that of people who in a game of chance have a better chance of winning because they just keep trying. Aristotle speaks here of people with a ‘garrulous and melancholic nature’ (l†lov kaª melagcolikŸ jÅsiv),24 who apparently serve as an example of the general rule that ‘quite common’ people (p†nu eÉtele±v Šnqrwpoi) have prophetic dreams. Melancholics are therefore implicitly contrasted with the group of ‘the best and most intelligent’ (see 462 b 21–2), for these would typically be expected to be the recipients of divine provision, if any such thing exists. This rather obscure passage is made even more difficult to interpret, as the explanation it gives for the prophetic dreams of melancholics seems to differ considerably from the one given in 463 b 17ff. This ability is based on a similarity (homoiotes¯ ) between the objects concerned. A further factor is the strength and intensity (sphodrotes¯ ) of their imagination, which prevents the process 23 For a discussion of the numerous difficulties involved in the interpretation of this paragraph see van der Eijk (1994) 289–301 [see also ch. For other interpretations of this passage see Barra (1957) 75–84; Boyance(´ 1936) 192; Croissant (1932) 36;Detienne (´ 1963) 140–69; Effe (1970) 82 n. Aristotle on melancholy 145 of association from being disturbed by other bodily movements. The eu- thuoneiria of melancholics (referred to here as eustochia, ability to make the right conjecture, which suggests a greater degree of activity)27 seems to be based on the ability to ‘perceive similarities’ (t‡v ¾moi»thtav qewre±n); on other occasions Aristotle relates this ability to a special natural disposi- tion (phusis or euphuia) and considers it an important principle for poetry and philosophy. In this passage Aristotle brackets melancholics together with the feverish and the intoxicated as examples of people who see confused and monstrous images in their sleep and whose dreams themselves are not coherent (oÉk –rrwm”na). The cause of this blurriness is that all these affec- tions contain air (pneumatÛdh) and therefore produce much movement and confusion. Yet even if this interpretation of euthuoneiros is adopted, it remains impos- sible to square Aristotle’s remark in Insomn. The ‘daemonic’ nature of the effect of the human phusis actually consists in the fact that it escapes rational control, i. See below (section 6) for the significance of this principle in Aristotle’s views on cognitive psychology. The fact that euthuoneiriai are opposed to ‘confused and disturbed images’ (e­dwla diapejorhm”na kaª diestramm”na)in464 b 9ff. For this reason these dreams can in fact be right or prophetic, yet this possibility also applies to the distorted and blurred images in dreams, for, Aristotle says, assessing their relation to reality clearly is the work of a professional interpreter of dreams. Another option is to assume that the confusing effect of air (pneuma) mentioned in On Dreams apparently does not apply in the cases referred to in On Divination in Sleep. This is either due to the large number of images (for, in On Divination in Sleep images seen in dreams are a result of movement, whereas On Dreams speaks about the influence of bodily movement on images that have already been formed),33 or because other psycho-physical processes or states neutralise, as it were, the confusing effect. Croissant),34 one has to assume that the contradiction is only apparent, but it must be admitted that Aristotle did not make an effort to avoid the impression of contradicting himself. Yet it is very well possible that this is partly due to the differences in aim and method between the more technical and programmatic On Dreams and the more polemical On Divination in 31 The noun eÉquoneir©a occurs in 463 a 25 and 464 b 7 and 16, the adjective eÉqu»neirov in 463 b 16 and 464 a 27 as well as in the passage Eth. Apart from the Aristotelian Corpus, the word does not occur until in Plutarch (De def. As to the meaning of this word, similar combinations with eÉqÅv are to be mentioned, such as eÉquwr©a (cf. AccordingtoCroissant,theeffectofthelackofrationalactivityinmelancholics is that the movements can reach the central sense organ, despite strong resistance of the air in the blood.

Raw nuts have good fats and provide pro- tein discount nolvadex 10mg free shipping, fiber purchase nolvadex pills in toronto, and provide a degree of satiety proven 20mg nolvadex. Also generic 10mg nolvadex fast delivery, some fat may help prevent gall bladder disease and improve vitamin absorption on a low-fat, plant based weight-reducing diet. The problem is many people eat handfuls of salted and roasted nuts (instead of raw), which have significant amounts of fat as well as salt. So I am al- ways cautious in recommending nut and seed consumption, which are inherently very nutritious and good foods. Remember, fat has two-and-a-half times the calories of a carbohydrate or protein per gram! Processed foods are not good for weight control for obvious reasons: They are calorie dense from added fats and oils and calo- rie sweeteners (sugars) and low in fiber and beneficial nutrients because the grains are refined. Animal foods, especially factory- farmed animal foods, and dairy products are very calorie-dense foods and generally don’t have beneficial fatty acid profiles and increase inflammation. To do this, you need to eat the foods with the highest nutrients per calorie (nutrient density) and the lowest amount of calories per weight (calorie density) that are packed with the most amount of protective phytonutrients (vitamins, minerals, antioxi- dants, phenolic compounds, etc. This formula is found in a plant- strong diet containing lots of vegetables, fruit, beans, some whole grains, and raw nuts and seeds. I am a vegetarian because of health, ecology, kindness to ani- mals, and spiritual reasons. Getting over the craving for meat is easier than dairy products, caffeine, or sugar. I allowed myself one hamburger a week, and that was the only meat I ate for several years. It is a personal journey, but this journey will change you and the planet for the better. I have maintained the same muscle mass for more than thirty years since playing college sports. Half of that time I was a meat eater and the other half I was a vegetarian, then vegan. I am as vain as any of you: I want to keep my muscles and maintain my athletic ability, too!

He felt he needed more animal protein to maintain his large muscle mass and strength to play pro football. If you read his book, The All-Pro Diet: Lose Fat, Build Muscle, and Live Like a Champion, you’ll see that he’s eating a 22 really clean diet that is still very highly plant-based. I hope what Tony Gonzalez has done in changing his diet to a whole-food diet and eating a lot more unprocessed, micronutri- ent-rich plant foods will positively influence professional athletes who are walking down a very unhealthy path, as well as non-pro- fessional athletes and kids looking at him as a role model. Instead of selling needless and potentially harmful protein supplements in gyms, they should sell Tony’s book. Though it’s not a vegan diet, it gets people pointed in the plant-strong direction. It should also be noted that Tony Gonzalez was significantly influenced to change to a more unprocessed plant-based diet after reading The China Study by T. Colin Campbell, PhD, which provides the science and evidence behind a worldwide shift to a strict plant- based diet to prevent and reverse chronic disease. The Animals Are Very Important Being a vegan also eliminates needless cruelty to animals. I never heard of anyone say that slaughterhouses and meat-packing plants are kind and “humane” to animals (and to their workers), es- pecially the limited number of people to whom I have spoken who have worked in them. There is not one scientific reason that we as humans have to eat a single bit of animal food to procreate, thrive, evolve, prevent disease, and be well as a human species. Some grain intolerant people will also feel much better and for many it’s easier to - 86 - the foundation for a staying healthy diet eliminate all grains than find the grain(s) that is causing the problem, as well as eat only whole grain products. Well-meaning but uninformed people think we need to eat animal foods to survive and thrive as human beings. I will repeat this one more time: There is no biological (evolu- tionary) reason any more that we have to eat meat to survive and thrive as a species in the modern world. So all this massive cruelty and suffering done to animals predominantly from factory farming is for no evolutionary purpose. So before any of you meat eaters misrepresent what I just said, let’s be very clear about what I’ve said: You can obviously be healthy eating small amounts of animal products, and most of the healthiest cultures in the world do it. What I did say, though, is that there is not a shred of scientific evidence that we have to eat another mouthful of animal foods to thrive and be well as a hu- man species. And there is a lot of evidence that a well thought out, high micronutrient vegetable-rich, whole-food, unrefined vegan diet is exactly what the world needs right now as far as preventing and reversing the chronic disease taxing ev- ery country’s healthcare system. Eliminating factory farming of animals for food consumption would also be a great thing for our environment in reducing greenhouse gases, conserving precious water resources, protecting our soil and rain forests, and reducing the spread of infectious diseases that come from the waste derived from the factory farming of billions of animals per year. We can get our anti-inflam- matory omega-3 fatty acids from the same places animals do: lots of green vegetation, sea vegetables, and some nuts and seeds. Jenkins stated in the Foreword to this book, not only will we lose species of fish but we will also affect the ecology of the ocean, which can only cause us harm. Secondly, if we try to remedy the situation with intensive fish farming to grow fish faster in cramped quarters, I predict un- healthy things will happen, as presently occurs with factory farm- ing of animals for food. Dairy and Grains There are a lot of competing ideas out there about what is good for you and what isn’t. This is particularly true when it comes to dairy products and grains, especially wheat. I could sum up my recom- mendations for the above in two simple statements: • Don’t eat dairy products in any shape or form from any ani- mal. Do this 100 percent for at least one month (no cheese, ice cream, sour cream, milk, butter, cottage cheese, yogurt, kefir) or preferably for a lifetime. Be very cautious with wheat and other glutinous grains, or go gluten free for one month. I have seen more suffering from common health complaints stopped immediately by eliminating dairy prod- ucts than any other single medical therapy. All you have to do is go off dairy products completely for at least three weeks, then reintroduce them. I have a list of scientific reasons why I think you should not eat dairy products. But don’t even read them if you are so locked into the false belief that dairy products are good for you and you have to eat them for strong bones and protein. If I have made any sense so far in this book, and you think I am sincere and reason- - 89 - staying healthy in the fast lane ably intelligent, then just take the “Ain’t Got Milk” challenge for one month and see for yourself. It will be abundantly clear that many of you will feel better, and many complaints—some mild, some seri- ous—will be eliminated. When I say the “Ain’t Got Milk” challenge, I mean all dairy products (milk, cheese, yogurt, ice cream, kefir, etc. I am not sure why the cravings last three weeks, but that has been my observation with milk products, especially cheeses. The harder and more ridiculous this concept of staying off milk products seems to you, the more I want you to try it! The most “stunned” people are usually the ones who have the most dramatic responses. Make sure you note any symptoms or bodily changes that occur while off dairy products and then pay atten- tion to what happens when you add them back into your diet. I know one thing you’re thinking: “How do I get calcium for my bones if I am off dairy products? A paper in 2009 in the well-respected American Journal of Clinical Nutrition by Dr. Amy Joy Lanou challenges this very issue of dairy products and bone loss-fracture prevention. Commenting on two very large studies, she states, “Both showed no protective effect of increased milk consumption on fracture risk. It notes that the countries with - 91 - staying healthy in the fast lane the highest calcium intakes have the highest hip fracture rates and those with the lowest calcium intake have the lowest. Fracture risk is associated with higher protein intake, which can cause more cal- cium spill in the urine. Lanou has co-authored (with Michael Castleman) an easily read and incredibly well-referenced book on this very topic, which I highly recommend (Building Bone Vitality, 2009) if you are fearful of your bones falling apart by not eating dairy products.
