The incidence of melanoma has been rising in most populations with predominantly European ancestry. Recent studies have documented the extremely high burden of mutations in the melanoma genome induced by ultraviolet radiation. This confirms earlier epidemiological observations that the incidence of melanoma is strongly correlated with ambient levels of solar radiation. The constitutional genes that confer susceptibility to melanoma include those associated with pigmentation characteristics as well as telomere length and cell-cycle control. Immunotherapies and targeted therapies have recently shown enormous promise in treating metastatic melanoma; this area of research is developing very quickly and will change rapidly in the next few years. Basal cell carcinomas and squamous cell carcinomas are the most common cancer types in humans. They are caused by sunlight and are largely preventable through control programmes. The primary diagnostic tool remains histopathology, and the histopathological patterns recognized by pathologists have now very clearly been shown to correspond to distinct genetic profiles. The tumours included in three of these pathways are common at sun-exposed sites, and the remainder are tumours that are less common (although important because of their global occurrence) and arise in sun-shielded skin, in mucosae, and in the eye. The melanomas that occur at sun-exposed sites are subdivided according to whether they are associated with a low degree or a high degree of cumulative sun damage [2]. Epidemiology In 2018, there were estimated to be almost 290 000 new cases of melanoma and about 61 000 deaths from melanoma worldwide [3]. The global range of population incidence of melanoma is the greatest of any cancer type. The incidence in a given region is determined largely by the pigmentation characteristics of individuals in that population and the ambient levels of solar radiation. The highest incidence is observed in the predominantly fairskinned populations living in areas with very high ambient levels of solar radiation, such as Australia and New Zealand (~50 per 100 000 person-years). In those populations, melanomas are the most common cancer type in people younger than 40 years, and are among the most common cancer type overall. The incidence of melanoma is also high in low-latitude parts of North America (~30 per 100 000 person-years), and there is an overall inverse gradient of incidence with increasing latitude. At higher latitudes in both North America and Europe, the incidence of melanoma has been rising steadily in recent decades; this trend is probably due to the advent of inexpensive leisure travel and the widespread use of tanning devices (sunlamps and sunbeds). Melanoma remains an uncommon cancer in Central and South America, Asia, Africa, and the Pacific (< 3 per 100 000 personyears). In recent years, the incidence of melanoma has been falling in Australia, particularly in more recent birth cohorts; this is consistent with the impact of prolonged public health campaigns (as discussed below). At the left is a plaque of early-stage superficial spreading melanoma in the radial growth phase. At the right, contiguous with the plaque, is a pink (amelanotic) nodule of deeply invasive melanoma in the vertical growth phase. Host factors that confer an increased risk of melanoma relate to the function or number of melanocytes. Overall, the strongest phenotypic risk factor for melanoma is the propensity to develop large numbers of melanocytic naevi (moles) on the skin. People with very large numbers of naevi (> 100) have risks of melanoma up to 7 times those in people with very few naevi (< 15) [5]. The pigmentation characteristics consistently associated with increased risks of melanoma include fair skin that burns and does not tan, red or light hair, blue eyes, and the propensity to develop freckles; therefore, melanoma is rare in populations with non-European ancestry [6]. However, for most patients genetic susceptibility is conferred through multiple polymorphisms in low-risk genes that act through many different pathways.

Elevated values from the average of two or more measurements on two or more clinical encounters are needed to diagnose hypertension. Lifestyle modifications should be prescribed in all patients with hypertension and prehypertension. Thiazide-type diuretics have traditionally been classified as first-line agents for treating most patients with hypertension. Although overall treatment should be the same, low initial doses should be used and dosage titrations should be gradual to minimize risk of orthostatic hypotension. Hypertensive urgency is ideally managed by adjusting maintenance therapy (adding a new antihypertensive and/or increasing the dose of a present medication). If a diuretic was not the first drug used, it should be the second drug add-on therapy for most patients.

Effective management of these problems is important because behavioral symptoms are distressing to both the patient and the caregiver, necessitate increased caregiver supervision and patience, and are a leading reason for nursing home placement. In fact, presence of neuropsychiatric symptoms increases caregiver burden more than loss of cognition or self-care. The need for medications may exist when neuropsychiatric symptoms are of sufficient severity to cause significant distress to the patient or caregiver, interfere with function or cause disability, impede delivery of necessary care, or pose a danger to self or others. Medications should be used cautiously, with adequate monitoring for efficacy and adverse events. Data from clinical trials of antidepressants, cholinesterase inhibitors, and antipsychotics are now emerging, but clearly more research is needed. Because of limited clinical data, treatment is primarily empiric, with side-effect profiles used as a guide in selecting the appropriate treatment. Psychotropic medications with anticholinergic effects should be avoided because they may actually worsen cognition and interfere with cholinesterase inhibitor therapy. Other side effects in the elderly include sedation, medication-induced postural instability, and extrapyramidal side effects, which can decrease the clinical usefulness of traditional psychotropic agents. General guidelines governing therapy can be summarized as follows: use reduced doses, monitor closely, titrate dosage slowly, and document carefully. Caregivers often have erroneous expectations regarding the effects of psychotropic medications, and the anticipated benefits and risks of therapy should be clearly explained. Attempts to slowly taper and discontinue antipsychotic medication should be undertaken regularly in minimally symptomatic patients, because some patients improve on medication withdrawal. Recent studies indicate that atypical and typical antipsychotics have been associated with infrequent but serious adverse events, including a small increased risk of death. Cholinesterase Inhibitors and Memantine Clinical trials with cholinesterase inhibitors have consistently reported modest benefit in managing neuropsychiatric symptoms, although these are generally not the primary outcomes studied in the trials. Long-term effects on behavior have not been demonstrated to date, and further research is needed. Based on a recent meta-analysis, only 17% to 18% of dementia patients show a treatment response to atypical antipsychotics. These adverse events associated with atypical antipsychotics include somnolence, extrapyramidal symptoms, abnormal gait, worsening cognition, cerebrovascular events, and increased risk of death. Diligent monitoring during treatment is essential along with frequent reassessment of continued need. Selected antipsychotics and antidepressants have been useful for effective management of behavioral, psychotic, and depressive symptoms, thereby easing caregiver burden and allowing the patient to spend additional time at home. Few studies provide prospective cost data from randomized controlled trials, and the data that does exist is for relatively short durations of therapy. Two clinical trials suggest that there is no benefit or disadvantage of donepezil compared to placebo in the cost of healthcare resource use. One cost analysis trial of memantine found that there was a trade-off between lower costs borne by the caregiver during treatment and higher drug costs borne by the patient. Until long-term data are available, the true cost benefit of various treatment approaches remains unknown. Small sample size, short duration of treatment, and differing measures of therapy outcomes limit comparison across studies and may account in part for conflicting study results. Serotonin/norepinephrine reuptake inhibitors such as venlafaxine may be an alternative. Miscellaneous Therapies Because antipsychotic and antidepressant therapy has shown only modest efficacy and poses a risk of undesirable side effects, medications traditionally used to treat disruptive behaviors and aggression in other psychiatric and neurologic disorders have been suggested as potential alternatives. These alternatives include benzodiazepines, buspirone, selegiline, carbamazepine, and valproic acid. Benzodiazepines, particularly oxazepam, have been used to treat anxiety, agitation, and aggression, but they generally show inferior 1063 however, the true cost-effectiveness of these therapies has yet to be established.

The reentrant circuit may possess both anatomically determined and functional properties coursing through 302 normal tissue, damaged (but not dead) tissue and islands of necrosed tissue. Torsade de pointes can be associated with heritable defects in the flux of ions that govern ventricular repolarization. An investigation should be made into possible precipitating factors and these should be corrected if possible. Because these patients are at extremely high risk for death, trial-and-error attempts to find effective therapy are unwarranted. These two strategies have been compared79,80 but largely abandoned for several reasons. In the latter patients, ablation is usually regarded as second-line therapy after other methods have failed. In addition, backup antibradycardia pacing and extended battery lives have made these newer devices much more attractive. All models store recordings during delivery of pacing shocks; this is extremely important in discerning appropriate from inappropriate shocks. First, the device itself, implantation procedure, electrophysiologic studies, hospitalization, and physician fees are costly. As a result of these trials, clinicians have sought a more clearly defined strategy for risk stratification in these patients before initiating drug therapy. It is believed that antiarrhythmic drugs may cause proarrhythmia in 5% to 20% of patients. Some patients who develop proarrhythmia may be totally asymptomatic, others may notice a worsening of symptoms, and some may die suddenly from this side effect. The development of proarrhythmia results from the same mechanisms that cause arrhythmias in general. However, in all cases, the agent should be discontinued if proarrhythmia is detected or suspected. Algorithm for the primary prevention of sudden cardiac death in patients with a history of myocardial infarction or with a nonischemic dilated cardiomyopathy. Provocation of proarrhythmia by the type Ic drugs is sometimes reported during exercise, which is most likely a result of augmented slowed conduction at rapid heart rates. In one study, in patients with risk factors, the incidence of death due to proarrhythmia from encainide and flecainide was approximately the same as the chance of long-term effectiveness! It has been proposed that the presence of underlying ventricular conduction delays may also pose a risk for proarrhythmia. As mentioned earlier, this arrhythmia is resistant to resuscitation; however, some have had success with lidocaine (competes for sodium channel receptor) or sodium bicarbonate (reverses the excessive sodium channel blockade). The underlying etiology in both cases is delayed ventricular repolarization due to blockade of potassium conductance. It is possible, however, that some individuals have a partially expressed form of these congenital syndromes but never suffer TdP unless some other external factor (drugs, diseases) further delays ventricular repolarization. Risk factors and associated features of drug-induced TdP have been identified and can be summarized as follows28,100: (a) high dosages or plasma concentrations of the offending agent ("dose-related") (except for quinidine-induced TdP, which tends to occur more frequently at low-to-therapeutic concentrations); (b) concurrent structural heart disease. However, none of these associations are absolute prerequisites to the occurrence of drug-induced TdP. For instance, although usually documented early in the course of therapy, patients may suffer TdP during chronic quinidine treatment. Note the presence of a couplet and two triplets following each extra systolic pause. The pause gets progressively longer until it is long enough to result in an episode of sustained torsade de pointes.
