Postmenopausal bleeding should always be investigated according to local guidelines. Women using non-hormonal contraception will experience the symptoms and signs of menopause in the same way as women not using any contraception. Most women using hormonal contraception will have altered bleeding patterns or amenorrhoea and as a result it can be difficult to give accurate advice regarding underlying menopausal status. In general, all women can cease contraception at the age of 55 as spontaneous conception after this age is exceptionally rare even in women still experiencing menstrual bleeding. If a woman age 55 or over does not wish to stop a particular method, consideration can be given to continuation providing the benefits and risks for her as an individual have been assessed and discussed with her. In general, all women can cease contraception at the age of 55, as spontaneous conception after this age is exceptionally uncommon even in women still experiencing some menstrual bleeding. There are complexities associated with measuring serum hormone levels in perimenopausal women and advising when to discontinue contraception. This should generally be restricted to women over the age of 50, as they are more likely to be menopausal. Continuous combined regimens (which administer both daily estrogen and progestogen) are not appropriate in perimenopause due to a high chance of irregular bleeding. There is no scientific evidence to confirm or refute this assumption but their usage is normally confined to postmenopausal women who, by definition, do not have a requirement for contraception. It is a licensed product for level 2 endometrial protection when combined with estrogen. There are extensive data showing that it is effective in providing protection from the stimulatory effects of estrogen on the endometrium. There are no data to support endometrial safety with these methods, and as they are not licensed for this use they cannot be recommended at the present time other than by specialist endorsement and informed choice. This has not been scientifically studied but it is highly likely to offer effective contraception through its local effect on cervical mucus and endometrial receptivity.

As a consequence, their coming to pare a few dozen dentists and fnd that they all the practice is not based on trust in that dentist prescribe diferent treatments, to bring damage to but on trust in the profession of dentistry. To prevent such disparities in treatment plans, the profession should inform both individ the recognized role of trust raises some ques ual dentists and the public at large of the accepted tions: standard of care for dentistry. Is the explication and elaboration of ethical defned as what would be done by the reasonably norms locally determined, or should they be prudent dentist in the same circumstances. How does a patient the Bolam case know the manner in which these norms should be applied in the daily practice? In order to de termine whether or not the hospital was negligent, In this chapter we will try to answer these ques the judge instructed the jury: tions. It is just a diferent way of expressing the the hallmark of professionalism is trustworthi same thought. It is the trust in the profession as a whole man is not negligent if he is acting in accordance that warrants patients’ trust in individual dentists. Nevertheless, one could argue that Standard of care the ethical principle of benefcence obliges a den tist also to see people with a simple toothache during the weekends. Technical aspects What if a patient wants treatment that is against the standard of care? What if a patient asks the dentist for treatment Indication the way treatment is performed that is against the standard of care? In many countries, the law forbids the dentist to di gress from the standard of care, unless following body of opinion who would take a contrary view. If the den At the same time, that does not mean that a med tist believes it is, the dentist will have to provide ical man can obstinately and pig-headedly carry scientifcally and clinically sound reasons to prove on with some old technique if it has been proved that following the standard is not in the best in to be contrary to what is really substantially the terest of this specifc patient. It covers technical aspects tient who is very afraid of the dentist and requests of dentistry – the indication of treatment and the to have his perfect teeth removed so he does not way treatment is performed. It also includes or have to face the dentist ever again, may be right in ganizational aspects of a practice, for instance, the the short term, but eventually he will most likely practice’s infection control or the duty to treat peo regret his request. The third group of aspects whose front teeth hurt so much that he asks the included in the standard are the patient’s rights. The dentist, for instance, cannot be dard of care represents this border between legal forced to perform a treatment that will harm the and illegal in matters of oral healthcare. It to remember, however, that even when an act is is unreasonable to expect an insurance company legal, it does not mean it is truly a good act, ethi to pay for treatment that will harm the patient. Suppose, for example, a local den And then there is the dental profession as a tal association has issued a rule that says patients whole. In order to get dental help, pa are evaluated according to the standards of the tients have to trust the individual dentist as well community. It is important to bear in mind that as the profession to work in their interest and to both of these standards focus on the dentists and cause no harm. Neither of them, are willing to start providing treatments standard is well-equipped to address the ever-in they themselves believe are not in the interest of creasing geographical movements of patients who the patient, the public will lose trust in the profes may come to dentists with culturally motivated re sion as a whole.

In other countries, front teeth are Because the standard of care is derived from the removed altogether. At frst sight, it may seem insights of peer dentists, the standard may change evident that extracting healthy teeth solely to over time as new graduates enter the practice of meet culturally defned ideas of beauty is harm dentistry. Then again, it is not uncommon for orthodon advised to rinse with turpentine after extraction – tists in Western countries to remove sound pre advice no dentist will give today. Decades ago, dentists used med within the standard of care in these Western coun ication that contained arsenic. Such changes can fect not only prevailing educational and technical actually happen within a short time span.

In adults, the conjunctiva of both tarsi—especially the lower tarsus—have papillae and follicles (Figure 5–4). Since pseudomembranes do not usually form in the adult, scarring does not usually occur. Superficial keratitis may be noted superiorly and, less often, a small superior micropannus (<1–2 mm). In the case of chlamydial ophthalmia neonatorum, rapid 213 diagnosis is also imperative to prevent systemic complications such as chlamydial pneumonitis. Inclusion conjunctivitis is usually caused by C trachomatis serovars D–K with occasional isolations of serotype B. Serologic determinations are not useful in the diagnosis of ocular infections, but measurement of IgM antibody levels is extremely valuable in the diagnosis of chlamydial pneumonitis in infants. Differential Diagnosis Usually inclusion conjunctivitis can be differentiated clinically from trachoma. Inclusion conjunctivitis occurs in sexually active adolescents or adults, whereas active, follicular trachoma usually occurs in young children or others living in or exposed to a community with endemic trachoma. In Infants Oral erythromycin suspension, 50 mg/kg/d in four divided doses for at least 14 days, is the treatment of choice. Systemic treatment is necessary because chlamydial infection also involves the respiratory and gastrointestinal tracts. In Adults In adults, cure of chlamydial disease can be achieved with azithromycin, 1 g in a single dose; doxycycline, 100 mg orally twice daily for 7 days; or erythromycin, 2 g/d for 7 days. If untreated, inclusion conjunctivitis runs a course of 3–9 months or longer with an average duration of 5 months. Strains from parrots (psittacosis) and cats (feline pneumonitis) have caused follicular conjunctivitis in humans. Severity ranges from mild, rapidly self-limited infection to severe, disabling disease. The follicles are often very prominent on both the conjunctiva and the pharyngeal mucosa. Injection and tearing often occur, and there may be transient superficial epithelial keratitis and occasionally some subepithelial opacities. Pharyngoconjunctival fever is most frequently caused by adenovirus type 3 and occasionally by types 4 and 7. As the disease progresses, it can be diagnosed serologically by a rising titer of neutralizing antibody. Conjunctival scrapings contain predominantly mononuclear cells, and no bacteria grow in cultures. The condition is more common in children than in adults and can be transmitted in poorly chlorinated swimming pools. The conjunctivitis is self-limited, and as such, only supportive treatment is indicated, with the episode resolving in approximately 10 days. The onset of epidemic keratoconjunctivitis is often unilateral, with both eyes subsequently being affected but the first eye usually being more severely affected. Usually by 5–14 days, photophobia, epithelial keratitis, and round subepithelial opacities have also developed. Edema of the eyelids, chemosis, and conjunctival hyperemia mark the acute phase, with follicles and subconjunctival hemorrhages often appearing within 48 hours. Pseudomembranes (and occasionally true membranes) may occur and may be followed by flat scars or 216 symblepharon formation. The subepithelial opacities are concentrated in the central cornea, usually sparing the periphery, and may persist for months but generally heal without scars. Epidemic keratoconjunctivitis is caused by adenovirus types 8, 19, 29, and 37 (subgroup D of the human adenoviruses). Scrapings from the conjunctiva show a primarily mononuclear inflammatory reaction; when pseudomembranes occur, neutrophils may also be prominent. Epidemic keratoconjunctivitis in adults is confined to the external eye, but in children, there may be systemic symptoms of viral infection, such as fever, sore throat, otitis media, and diarrhea. Nosocomial transmission may occur during eye examinations, especially by use of improperly sterilized ophthalmic instruments such as tonometer tips or use of contaminated solutions, particularly topical anesthetics. There is no specific therapy, but cold compresses and artificial tears will relieve some symptoms. Corticosteroids used during acute conjunctivitis may prolong late corneal involvement and should be avoided whenever possible. It is often associated with herpes simplex keratitis, in which the cornea shows discrete epithelial lesions that usually coalesce to form single or multiple branching epithelial (dendritic) ulcers (Figure 5–7). If the conjunctivitis is follicular, the predominant inflammatory reaction is mononuclear, but if it is pseudomembranous, the predominant reaction is polymorphonuclear, owing to the chemotaxis of necrosis. Intranuclear inclusions can be seen in conjunctival and corneal cells if Bouin fixation and the Papanicolaou stain are used but not in Giemsa-stained smears. The virus can be readily isolated by gently rubbing a dry Dacron or calcium alginate swab over the conjunctiva and transferring the infected cells to a susceptible tissue culture. Complications consist of corneal involvement (including dendrites) and vesicles on the skin. Although type 1 herpesvirus causes the overwhelming majority of ocular cases, type 2 is the usual cause of herpetic conjunctivitis in newborns and a rare cause in adults. If the conjunctivitis occurs in a child over 1 year of age or in an adult, it is usually self-limited and may not require therapy. Topical or systemic antivirals should be given, however, to prevent corneal involvement. For corneal ulcers, corneal debridement may be performed by gently wiping the ulcer with a dry cotton swab, applying antiviral drops, and patching the eye for 24 hours. Topical antivirals alone should be applied for 7–10 days (eg, trifluridine every 2 hours while awake or ganciclovir aqueous gel 0. Herpetic keratitis may also be treated with 3% acyclovir ointment (not available in the United States) five times daily for 10 days, or with oral acyclovir, 400 mg five times daily for 7 days. Corticosteroid use is contraindicated since it may aggravate herpetic infections, causing a prolonged and usually more severe course. Newcastle Disease Conjunctivitis Newcastle disease conjunctivitis is a rare disorder characterized by burning, itching, pain, redness, tearing, and (rarely) blurring of vision. It often occurs in small epidemics among poultry workers handling infected birds or among veterinarians or laboratory helpers working with live vaccines or virus. The conjunctivitis resembles that caused by other viral agents, with chemosis, a small preauricular node, and follicles on the upper and lower tarsus. Acute Hemorrhagic Conjunctivitis All of the continents and most of the islands of the world have had major epidemics of acute hemorrhagic conjunctivitis, which is caused by enterovirus type 70 and occasionally by coxsackievirus A24. Characteristically, the disease has a short incubation period (8–48 hours) and course (5–7 days). The usual signs and symptoms are pain, photophobia, foreign-body sensation, copious tearing, redness, lid edema, and subconjunctival hemorrhages. The subconjunctival hemorrhages are usually diffuse but may be punctate at onset, beginning in the upper bulbar conjunctiva and spreading to the lower. Most patients have 219 preauricular lymphadenopathy, conjunctival follicles, and epithelial keratitis. Anterior uveitis has been reported; fever, malaise, and generalized myalgia have been observed in 25% of cases; and motor paralysis of the lower extremities has occurred in rare cases in India and Japan. The virus is transmitted by close person-to-person contact and by such fomites as common linens, contaminated optical instruments, and water. Biopsy shows eosinophilic cytoplasmic inclusions that fill the entire cytoplasm of the enlarged cell, pushing its nucleus to one side. A nodule on the lid margin (Figure 5–8) or the skin of the lids or brow may produce unilateral chronic follicular conjunctivitis, superior keratitis, and superior pannus resembling trachoma. The inflammatory reaction is predominantly mononuclear (unlike the reaction in trachoma). Molluscum contagiosum nodule on the lid margin that was causing chronic follicular conjunctivitis. Varicella-Zoster Blepharoconjunctivitis Hyperemia and an infiltrative conjunctivitis—associated with the typical vesicular eruption along the dermatomal distribution of the ophthalmic branch of the trigeminal nerve (Figure 5–9)—are characteristic of ophthalmic (herpes) zoster (shingles), due to reactivation of varicella-zoster virus infection. The conjunctivitis is usually papillary, but follicles, pseudomembranes, and transitory vesicles that later ulcerate have all been noted.
