Healthy Living

Achalasia, also known as esophageal achalasia, achalasia cardiae, cardiospasm, and esophageal aperistalsis, is an esophageal motility disorder: The smooth muscle layer of the esophagus loses normal peristalsis (muscular ability to move food down the esophagus), and the lower esophageal sphincter (LES) fails to relax properly in response to swallowing.

Achalasia is characterized by difficulty swallowing, regurgitation, and sometimes chest pain. Diagnosis is reached with esophageal manometry and barium swallow X-ray studies. Various treatments are available, although none cure the condition completely. Certain medications or Botox may be used in some cases, but more permanent relief is brought by esophageal dilatation and surgical cleaving of the muscle (Heller myotomy).

Causes

The most common form is primary achalasia, which has no known underlying cause. However, a small proportion occurs as a secondary result of other conditions, such as esophageal cancer or Chagas disease (an infectious disease common in South America).Achalasia affects about one person in 100,000 per year.

Signs and Symptoms

The main symptoms of achalasia are dysphagia (difficulty in swallowing) and regurgitation of undigested food. Dysphagia tends to become progressively worse over time and to involve both fluids and solids. Some achalasia patients also experience weight loss, coughing when lying in a horizontal position, and chest pain which may be perceived as heartburn. Food and liquid, including saliva, are retained in the esophagus and may be inhaled into the lungs (aspiration),y potentially leading to aspiration pneumonia.

Treatment

Medication

Drugs that reduce LES pressure may be useful, especially as a way to buy time while waiting for surgical treatment. These include calcium channel blockers such as nifedipine, and nitrates such as isosorbide dinitrate and nitroglycerin. However, many patients experience unpleasant side effects such as headache and swollen feet, and these drugs often stop helping after several months.

Botulinum toxin (Botox) may be injected into the lower esophageal sphincter to paralyze the muscles holding it shut. As in the case of cosmetic Botox, the effect is only temporary, and symptoms return relatively quickly in most patients. Botox injections cause scarring in the sphincter which may increase the difficulty of later Heller myotomy. This therapy is only recommended for patients who cannot risk surgery, such as elderly persons in poor health.

Pneumatic dilatation

In balloon (pneumatic) dilation or dilatation, the muscle fibers are stretched and slightly torn by forceful inflation of a balloon placed inside the lower esophageal sphincter. Gastroenterologists who specialize in achalasia and have performed many of these forceful balloon dilatations achieve better results and fewer perforations. There is always a small risk of a perforation which requires immediate surgical repair. Pneumatic dilatation causes some scarring which may increase the difficulty of Heller myotomy if the surgery is needed later. Gastroesophageal reflux (GERD) occurs after pneumatic dilatation in some patients. Pneumatic dilatation is most effective on the long term in patients over the age of 40; the benefits tend to be shorter-lived in younger patients. It may need to be repeated with larger balloons for maximum effectiveness.

Surgery

Heller myotomy helps 90% of achalasia patients. It can usually be performed by a keyhole approach, or laparoscopically. The myotomy is a lengthwise cut along the esophagus, starting above the LES and extending down onto the stomach a little way. The esophagus is made of several layers, and the myotomy only cuts through the outside muscle layers which are squeezing it shut, leaving the inner muscosal layer intact. A partial fundoplication or “wrap” is generally added in order to prevent excessive reflux, which can cause serious damage to the esophagus over time. After surgery, patients should keep to a soft diet for several weeks to a month, avoiding foods that can aggravate reflux.

Alternative medicine

Temporary improvement of achalasia symptoms in some cases has been reported with acupuncture, traditional Chinese herbal medicine, and relaxation techniques.

Lifestyle changes

Both before and after treatment, achalasia patients may need to eat slowly, chew very well, drink plenty of water with meals, and avoid eating near bedtime. Raising the head of the bed or sleeping with a wedge pillow promotes emptying of the esophagus by gravity. After surgery or pneumatic dilatation, proton pump inhibitors can help prevent reflux damage by inhibiting gastric acid secretion; and foods that can aggravate reflux, including ketchup, citrus, chocolate, mint, alcohol, and caffeine, may need to be avoided.

Lactose intolerance is an inability to digest and absorb lactose (the sugar in milk) that results in gastrointestinal symptoms when milk or products containing milk are drunk or eaten.

Causes

Lactose is a larger sugar that is made up of two smaller sugars, glucose and  galactose. In order for lactose to be absorbed from the intestine and into the body, it must first be split into glucose and galactose. The glucose and galactose then are absorbed by the cells lining the small intestine. The enzyme that splits lactose into glucose and galactose is called lactase, and it is located on the surface of the cells that line the small intestine.

Lactose intolerance is caused by reduced or absent activity of lactase that prevents the splitting of lactose (lactase deficiency). Lactase deficiency may occur for one of three reasons, congenital, secondary or developmental.

Symptoms

The common symptoms of lactose intolerance are gastrointestinal, primarily,  abdominal pain, diarrhea , flatulence (passing gas), and, less commonly, abdominal bloating, abdominal distention, and nausea. Unfortunately, these symptoms can be caused by other gastrointestinal conditions or diseases, so the presence of these symptoms is not very good at predicting whether a person has lactase deficiency or lactose intolerance.

Symptoms occur because the unabsorbed lactose passes through the small intestine and into the colon. In the colon, one type of normal bacterium contains lactase and is able to split the lactose and use the resulting glucose and galactose for its own purposes. Unfortunately, when they use the glucose and galactose, these bacteria also release hydrogen gas. Some of the gas is absorbed from the colon and into the body and is then expelled by the lungs in the breath. Most of the hydrogen, however, is used up in the colon by other types of bacteria. A small proportion of the hydrogen gas is expelled and is responsible for the increased flatus (passing gas). Some people have an additional type of bacterium in their colons that changes the hydrogen gas into methane gas, and these people will excrete only methane or both hydrogen and methane gas in their breath and flatus.

Not all of the lactose that reaches the colon is split and used by colonic bacteria. The unsplit lactose in the colon draws water into the colon (by osmosis). This leads to loose, diarrheal stools.

The severity of the symptoms of lactose intolerance vary greatly from person to person. One reason for this variability is that people have different amounts of lactose in their diet; the more lactose in the diet, the more likely and severe the symptoms. Another reason for the variability is that people have differing severities of lactase deficiency, that is, they may have mildly, moderately, or severely reduced amounts of lactase in their intestines. Thus, small amounts of lactose will cause major symptoms in severely lactase deficient people but only mild or no symptoms in mildly lactase deficient people. Finally, people may have different responses to the same amount of lactose reaching the colon. Whereas some may have mild or no symptoms, others may have moderate symptoms. The reason for this is not clear but may relate to differences in their intestinal bacteria.

Treatment

Dietary changes

The most obvious means of treating lactose intolerance is by reducing the amount of lactose in the diet. Fortunately, most people who are lactose intolerant can tolerate small or even moderate amounts of lactose. It often takes only elimination of the major milk-containing products to obtain sufficient relief from their symptoms. Thus, it may be necessary to eliminate only milk, yogurt, cottage cheese, and ice cream. Though yogurt contains large amounts of lactose, it often is well-tolerated by lactose intolerant people. This may be so because the bacteria used to make yogurt contain lactase, and the lactase is able to split the lactose during storage of the yogurt as well as after the yogurt is eaten (in the stomach and intestine). Yogurt also has been shown to empty more slowly from the stomach than an equivalent amount of milk. This allows more time for intestinal lactase to split the lactose in yogurt, and, at least theoretically, would result in less lactose reaching the colon.

Most supermarkets carry milk that has had the lactose already split by the addition of lactase. Substitutes for milk also are available, including soy and rice milk. Acidophilus-containing milk is not beneficial since it contains as much lactose as regular milk, and acidophilus bacteria do not split lactose.

For individuals who are intolerant to even small amounts of lactose, the dietary restrictions become more severe. Any purchased product containing milk must be avoided. It is especially important to eliminate prepared foods containing milk purchased from the supermarket and dishes from restaurants that have sauces.

Another means to reduce symptoms of lactose intolerance is to ingest any milk-containing foods during meals. Meals (particularly meals containing fat) reduce the rate at which the stomach empties into the small intestine. This reduces the rate at which lactose enters the small intestine and allows more time for the limited amount of lactase to split the lactose without being overwhelmed by the full load of lactose at once. Studies have shown that the absorption of lactose from whole milk, which contains fat, is greater than from non-fat milk, perhaps for this very reason. Nevertheless, the substitution of whole milk or yogurt for non-fat milk or yogurt does not seem to reduce the symptoms of lactose intolerance.

Lactase enzyme

Caplets or tablets of lactase are available to take with milk-containing foods.

Adaptation

Some people find that by slowly increasing the amount of milk or milk-containing products in their diets they are able to tolerate larger amounts of lactose without developing symptoms. This adaptation to increasing amounts of milk is not due to increases in lactase in the intestine. Adaptation probably results from alterations to the bacteria in the colon. Increasing amounts of lactose entering the colon change the colonic environment, for example, by increasing the acidity of the colon. These changes alter the way in which the colonic bacteria handle lactose. For example, the bacteria produce less gas. There also may be a reduction in the secretion of water and, therefore, less diarrhea.

Calcium and vitamin D supplements

Milk and milk-containing products are the best sources of dietary calcium, so it is no wonder that calcium deficiency is common among lactose intolerant persons. This increases the risk and severity of osteoporosis and the resulting bone fractures. It is important, therefore, for lactose intolerant persons to supplement their diets with calcium. A deficiency of vitamin D also causes disease of the bones and fractures. Milk is fortified with vitamin D and is a major source of vitamin D for many people. Although other sources of vitamin D can substitute for milk, it is a good idea for lactose-intolerant persons to take supplemental vitamin D to prevent vitamin D deficiency.

Alzheimer’s disease (AD) is a slowly progressive disease of the brain that is characterized by impairment of memory and eventually by disturbances in reasoning, planning, language, and perception.

Risk Factors

The main risk factor for Alzheimer’s disease is increased age. As a population ages, the frequency of Alzheimer’s disease continues to increase. Ten percent of people over 65 years of age and 50% of those over 85 years of age have Alzheimer’s disease. Unless new treatments are developed to decrease the likelihood of developing Alzheimer’s disease, the number of individuals with Alzheimer’s disease in the United States is expected to be 14 million by the year 2050.

There are also genetic risk factors for Alzheimer’s disease. Most patients develop Alzheimer’s disease after age 70. However, 2%-5% of patients develop the disease in the fourth or fifth decade of life (40s or 50s). At least half of these early onset patients have inherited gene mutations associated with their Alzheimer’s disease. Moreover, the children of a patient with early onset Alzheimer’s disease who has one of these gene mutations has a 50% risk of developing Alzheimer’s disease.

There is also a genetic risk for late onset cases. A relatively common form of a gene located on chromosome 19 is associated with late onset Alzheimer’s disease. In the majority of Alzheimer’s disease cases, however, no specific genetic risks have yet been identified.

Other risk factors for Alzheimer’s disease include high blood pressure (hypertension), coronary artery disease, diabetes, and possibly elevated blood cholesterol. Individuals who have completed less than eight years of education also have an increased risk for Alzheimer’s disease. These factors increase the risk of Alzheimer’s disease, but by no means do they mean that Alzheimer’s disease is inevitable in persons with these factors.

Symptoms

The onset of Alzheimer’s disease is usually gradual, and it is slowly progressive. Memory problems that family members initially dismiss as “a normal part of aging” are in retrospect noted by the family to be the first stages of Alzheimer’s disease. When memory and other problems with thinking start to consistently affect the usual level of functioning; families begin to suspect that something more than “normal aging” is going on.

Problems of memory, particularly for recent events (short-term memory) are common early in the course of Alzheimer’s disease. For example, the individual may, on repeated occasions, forget to turn off an iron or fail to recall which of the morning’s medicines were taken. Mild personality changes, such as less spontaneity, apathy, and a tendency to withdraw from social interactions, may occur early in the illness.

As the disease progresses, problems in abstract thinking and in other intellectual functions develop. The person may begin to have trouble with figures when working on bills, with understanding what is being read, or with organizing the day’s work. Further disturbances in behavior and appearance may also be seen at this point, such as agitation, irritability, quarrelsomeness, and a diminishing ability to dress appropriately.

Later in the course of the disorder, affected individuals may become confused or disoriented about what month or year it is, be unable to describe accurately where they live, or be unable to name a place being visited. Eventually, patients may wander, be unable to engage in conversation, erratic in mood, uncooperative, and lose bladder and bowel control. In late stages of the disease, persons may become totally incapable of caring for themselves. Death can then follow, perhaps from pneumonia or some other problem that occurs in severely deteriorated states of health. Those who develop the disorder later in life more often die from other illnesses (such as heart disease) rather than as a consequence of Alzheimer’s disease.

Warning Signs

The Alzheimer’s Association has developed the following list of warning signs that include common symptoms of Alzheimer’s disease. Individuals who exhibit several of these symptoms should see a physician for a complete evaluation.

1. Memory loss

2. Difficulty performing familiar tasks

3. Problems with language

4. Disorientation to time and place

5. Poor or decreased judgment

6. Problems with abstract thinking

7. Misplacing things

8. Changes in mood or behavior

9. Changes in personality

10. Loss of initiative

Causes

The cause(s) of Alzheimer’s disease is (are) not known. The “amyloid cascade hypothesis” is the most widely discussed and researched hypothesis about the cause of Alzheimer’s disease. The strongest data supporting the amyloid cascade hypothesis comes from the study of early-onset inherited (genetic) Alzheimer’s disease. Mutations associated with Alzheimer’s disease have been found in about half of the patients with early-onset disease. In all of these patients, the mutation leads to excess production in the brain of a specific form of a small protein fragment called ABeta (Aβ). Many scientists believe that in the majority of sporadic (for example, non-inherited) cases of Alzheimer’s disease (these make up the vast majority of all cases of Alzheimer’s disease) there is too little removal of this Aβ protein rather than too much production. In any case, much of the research in finding ways to prevent or slow down Alzheimer’s disease has focused on ways to decrease the amount of Aβ in the brain.

Diagnosis

As of June 2007, there is no specific “blood test” or imaging test that is used for the diagnosis of Alzheimer’s disease. Alzheimer’s disease is diagnosed when: 1) a person has sufficient cognitive decline to meet criteria for dementia; 2) the clinical course is consistent with that of Alzheimer’s disease; 3) no other brain diseases or other processes are better explanations for the dementia.

Treatment and Management

The management of Alzheimer’s disease consists of medication based and non-medication based treatments. Two different classes of pharmaceuticals are approved by the FDA for treating Alzheimer’s disease: cholinesterase inhibitors and partial glutamate antagonists. Neither class of drugs has been proven to slow the rate of progression of Alzheimer’s disease. Nonetheless, many clinical trials suggest that these medications are superior to placebos (sugar pills) in relieving some symptoms.

Cholinesterase inhibitors

In patients with Alzheimer’s disease there is a relative lack of a brain chemical neurotransmitter called acetylcholine. (Neurotransmitters are chemical messengers produced by nerves that the nerves use to communicate with each other in order to carry out their functions.) Substantial research has demonstrated that acetylcholine is important in the ability to form new memories. The cholinesterase inhibitors (ChEIs) block the breakdown of acetylcholine. As a result, more acetylcholine is available in the brain, and it may become easier to form new memories.

Four ChEIs have been approved by the FDA, but only donepezil hydrochloride (Aricept), rivastigmine (Exelon), and galantamine (Razadyne - previously called Reminyl) are used by most physicians because the fourth drug, tacrine (Cognex) has more undesirable side effects than the other three. Most experts in Alzheimer’s disease do not believe there is an important difference in the effectiveness of these three drugs. Several studies suggest that the progression of symptoms of patients on these drugs seems to plateau for six to 12 months, but inevitably progression then begins again.

Of the three widely used AchEs, rivastigmine and galantamine are only approved by the FDA for mild to moderate Alzheimer’s disease, whereas donepezil is approved for mild, moderate, and severe Alzheimer’s disease. It is not known whether rivastigmine and galantamine are also effective in severe Alzheimer’s disease, although there does not appear to be any good reason why they shouldn’t.

The principal side effects of ChEIs involve the gastrointestinal system and include nausea, vomiting, cramping, and diarrhea. Usually these side effects can be controlled with change in size or timing of the dose or administering the medications with a small amount of food. Between 75% and 90% of patients will tolerate therapeutic doses of ChEIs.

Schizophrenia is a chronic, severe, and disabling brain disorder that has been recognized throughout recorded history. It affects about 1 percent of Americans.
People with schizophrenia may hear voices other people don’t hear or they may believe that others are reading their minds, controlling their thoughts, or plotting to harm them. These experiences are terrifying and can cause fearfulness, withdrawal, or extreme agitation. People with schizophrenia may not make sense when they talk, may sit for hours without moving or talking much, or may seem perfectly fine until they talk about what they are really thinking. Because many people with schizophrenia have difficulty holding a job or caring for themselves, the burden on their families and society is significant as well.

Symptoms

a.Positive symptoms

Positive symptoms are easy-to-spot behaviors not seen in healthy people and usually involve a loss of contact with reality. They include hallucinations, delusions, thought disorder, and disorders of movement. Positive symptoms can come and go. Sometimes they are severe and at other times hardly noticeable, depending on whether the individual is receiving treatment.

Hallucinations. A hallucination is something a person sees, hears, smells, or feels that no one else can see, hear, smell, or feel. “Voices” are the most common type of hallucination in schizophrenia. Many people with the disorder hear voices that may comment on their behavior, order them to do things, warn them of impending danger, or talk to each other (usually about the patient). They may hear these voices for a long time before family and friends notice that something is wrong. Other types of hallucinations include seeing people or objects that are not there, smelling odors that no one else detects (although this can also be a symptom of certain brain tumors), and feeling things like invisible fingers touching their bodies when no one is near.

Delusions. Delusions are false personal beliefs that are not part of the person’s culture and do not change, even when other people present proof that the beliefs are not true or logical. People with schizophrenia can have delusions that are quite bizarre, such as believing that neighbors can control their behavior with magnetic waves, people on television are directing special messages to them, or radio stations are broadcasting their thoughts aloud to others. They may also have delusions of grandeur and think they are famous historical figures. People with paranoid schizophrenia can believe that others are deliberately cheating, harassing, poisoning, spying upon, or plotting against them or the people they care about. These beliefs are called delusions of persecution.

Thought Disorder. People with schizophrenia often have unusual thought processes. One dramatic form is disorganized thinking, in which the person has difficulty organizing his or her thoughts or connecting them logically. Speech may be garbled or hard to understand. Another form is “thought blocking,” in which the person stops abruptly in the middle of a thought. When asked why, the person may say that it felt as if the thought had been taken out of his or her head. Finally, the individual might make up unintelligible words, or “neologisms.”

Disorders of Movement. People with schizophrenia can be clumsy and uncoordinated. They may also exhibit involuntary movements and may grimace or exhibit unusual mannerisms. They may repeat certain motions over and over or, in extreme cases, may become catatonic. Catatonia is a state of immobility and unresponsiveness. It was more common when treatment for schizophrenia was not available; fortunately, it is now rare.

b.Negative symptoms

The term “negative symptoms” refers to reductions in normal emotional and behavioral states. These include the following:

* flat affect (immobile facial expression, monotonous voice),

* lack of pleasure in everyday life,

* diminished ability to initiate and sustain planned activity, and

* speaking infrequently, even when forced to interact.

People with schizophrenia often neglect basic hygiene and need help with everyday activities. Because it is not as obvious that negative symptoms are part of a psychiatric illness, people with schizophrenia are often perceived as lazy and unwilling to better their lives.

c.Cognitive symptoms

Cognitive symptoms are subtle and are often detected only when neuropsychological tests are performed. They include the following:

* poor “executive functioning” (the ability to absorb and interpret information and make decisions based on that information),

* inability to sustain attention, and

* problems with “working memory” (the ability to keep recently learned information in mind and use it right away)

Cognitive impairments often interfere with the patient’s ability to lead a normal life and earn a living. They can cause great emotional distress.

Causes

Like many other illnesses, schizophrenia is believed to result from a combination of environmental and genetic factors. All the tools of modern science are being used to search for the causes of this disorder.

Treatment

Because the causes of schizophrenia are still unknown, current treatments focus on eliminating the symptoms of the disease.

Antipsychotic medications

Antipsychotic medications have been available since the mid-1950s. They effectively alleviate the positive symptoms of schizophrenia. While these drugs have greatly improved the lives of many patients, they do not cure schizophrenia.

Everyone responds differently to antipsychotic medication. Sometimes several different drugs must be tried before the right one is found. People with schizophrenia should work in partnership with their doctors to find the medications that control their symptoms best with the fewest side effects.

The older antipsychotic medications include chlorpromazine (Thorazine®), haloperidol (Haldol®), perphenazine (Etrafon®, Trilafon®), and fluphenazine (Prolixin®). The older medications can cause extrapyramidal side effects, such as rigidity, persistent muscle spasms, tremors, and restlessness.

In the 1990s, new drugs, called atypical antipsychotics, were developed that rarely produced these side effects. The first of these new drugs was clozapine (Clozaril®). It treats psychotic symptoms effectively even in people who do not respond to other medications, but it can produce a serious problem called agranulocytosis, a loss of the white blood cells that fight infection. Therefore, patients who take clozapine must have their white blood cell counts monitored every week or two. The inconvenience and cost of both the blood tests and the medication itself has made treatment with clozapine difficult for many people, but it is the drug of choice for those whose symptoms do not respond to the other antipsychotic medications, old or new.

Some of the drugs that were developed after clozapine was introduced-such as risperidone (Risperdal®), olanzapine (Zyprexa®), quetiapine (Seroquel®), sertindole (Serdolect®), and ziprasidone (Geodon®)-are effective and rarely produce extrapyramidal symptoms and do not cause agranulocytosis; but they can cause weight gain and metabolic changes associated with an increased risk of diabetes and high cholesterol.

People respond individually to antipsychotic medications, although agitation and hallucinations usually improve within days and delusions usually improve within a few weeks. Many people see substantial improvement in both types of symptoms by the sixth week of treatment. No one can tell beforehand exactly how a medication will affect a particular individual, and sometimes several medications must be tried before the right one is found.

When people first start to take atypical antipsychotics, they may become drowsy; experience dizziness when they change positions; have blurred vision; or develop a rapid heartbeat, menstrual problems, a sensitivity to the sun, or skin rashes. Many of these symptoms will go away after the first days of treatment, but people who are taking atypical antipsychotics should not drive until they adjust to their new medication.

If people with schizophrenia become depressed, it may be necessary to add an antidepressant to their drug regimen.

A large clinical trial funded by the National Institute of Mental Health (NIMH), known as CATIE (Clinical Antipsychotic Trials of Intervention Effectiveness), compared the effectiveness and side effects of five antipsychotic medications-both new and older antipsychotics-that are used to treat people with schizophrenia. For more information, visit the NIMH CATIE page.

Length of Treatment. Like diabetes or high blood pressure, schizophrenia is a chronic disorder that needs constant management. At the moment, it cannot be cured, but the rate of recurrence of psychotic episodes can be decreased significantly by staying on medication. Although responses vary from person to person, most people with schizophrenia need to take some type of medication for the rest of their lives as well as use other approaches, such as supportive therapy or rehabilitation.

Relapses occur most often when people with schizophrenia stop taking their antipsychotic medication because they feel better, or only take it occasionally because they forget or don’t think taking it regularly is important. It is very important for people with schizophrenia to take their medication on a regular basis and for as long as their doctors recommend. If they do so, they will experience fewer psychotic symptoms.

No antipsychotic medication should be discontinued without talking to the doctor who prescribed it, and it should always be tapered off under a doctor’s supervision rather than being stopped all at once.

There are a variety of reasons why people with schizophrenia do not adhere to treatment. If they don’t believe they are ill, they may not think they need medication at all. If their thinking is too disorganized, they may not remember to take their medication every day. If they don’t like the side effects of one medication, they may stop taking it without trying a different medication. Substance abuse can also interfere with treatment effectiveness. Doctors should ask patients how often they take their medication and be sensitive to a patient’s request to change dosages or to try new medications to eliminate unwelcome side effects.

There are many strategies to help people with schizophrenia take their drugs regularly. Some medications are available in long-acting, injectable forms, which eliminate the need to take a pill every day. Medication calendars or pillboxes labeled with the days of the week can both help patients remember to take their medications and let caregivers know whether medication has been taken. Electronic timers on clocks or watches can be programmed to beep when people need to take their pills, and pairing medication with routine daily events, like meals, can help patients adhere to dosing schedules.

Medication Interactions. Antipsychotic medications can produce unpleasant or dangerous side effects when taken with certain other drugs. For this reason, the doctor who prescribes the antipsychotics should be told about all medications (over-the-counter and prescription) and all vitamins, minerals, and herbal supplements the patient takes. Alcohol or other drug use should also be discussed.

Psychosocial treatment

Numerous studies have found that psychosocial treatments can help patients who are already stabilized on antipsychotic medications deal with certain aspects of schizophrenia, such as difficulty with communication, motivation, self-care, work, and establishing and maintaining relationships with others. Learning and using coping mechanisms to address these problems allows people with schizophrenia to attend school, work, and socialize. Patients who receive regular psychosocial treatment also adhere better to their medication schedule and have fewer relapses and hospitalizations. A positive relationship with a therapist or a case manager gives the patient a reliable source of information, sympathy, encouragement, and hope, all of which are essential for for managing the disease. The therapist can help patients better understand and adjust to living with schizophrenia by educating them about the causes of the disorder, common symptoms or problems they may experience, and the importance of staying on medications.

Illness Management Skills. People with schizophrenia can take an active role in managing their own illness. Once they learn basic facts about schizophrenia and the principles of schizophrenia treatment, they can make informed decisions about their care. If they are taught how to monitor the early warning signs of relapse and make a plan to respond to these signs, they can learn to prevent relapses. Patients can also be taught more effective coping skills to deal with persistent symptoms.

Integrated Treatment for Co-occurring Substance Abuse. Substance abuse is the most common co-occurring disorder in people with schizophrenia, but ordinary substance abuse treatment programs usually do not address this population’s special needs. Integrating schizophrenia treatment programs and drug treatment programs produces better outcomes.

Rehabilitation. Rehabilitation emphasizes social and vocational training to help people with schizophrenia function more effectively in their communities. Because people with schizophrenia frequently become ill during the critical career-forming years of life (ages 18 to 35) and because the disease often interferes with normal cognitive functioning, most patients do not receive the training required for skilled work. Rehabilitation programs can include vocational counseling, job training, money management counseling, assistance in learning to use public transportation, and opportunities to practice social and workplace communication skills.

Family Education. Patients with schizophrenia are often discharged from the hospital into the care of their families, so it is important that family members know as much as possible about the disease to prevent relapses. Family members should be able to use different kinds of treatment adherence programs and have an arsenal of coping strategies and problem-solving skills to manage their ill relative effectively. Knowing where to find outpatient and family services that support people with schizophrenia and their caregivers is also valuable.

Cognitive Behavioral Therapy. Cognitive behavioral therapy is useful for patients with symptoms that persist even when they take medication. The cognitive therapist teaches people with schizophrenia how to test the reality of their thoughts and perceptions, how to “not listen” to their voices, and how to shake off the apathy that often immobilizes them. This treatment appears to be effective in reducing the severity of symptoms and decreasing the risk of relapse.

Self-Help Groups. Self-help groups for people with schizophrenia and their families are becoming increasingly common. Although professional therapists are not involved, the group members are a continuing source of mutual support and comfort for each other, which is also therapeutic. People in self-help groups know that others are facing the same problems they face and no longer feel isolated by their illness or the illness of their loved one. The networking that takes place in self-help groups can also generate social action. Families working together can advocate for research and more hospital and community treatment programs, and patients acting as a group may be able to draw public attention to the discriminations many people with mental illnesses still face in today’s world.

Support groups and advocacy groups are excellent resources for people with many types of mental disorders.

Psoriasis is a common inherited condition characterized by eruption of circumscribed, discrete and confluent, reddish, silvery-scaled maculopapules.

Psoriasis occurs as small spots anywhere on the body or it involves the large areas.

Psoriasis is considered a long-term (chronic) skin condition. It has a variable course with periodic ups and downs. Sometimes psoriasis may clear for years and stay in remission. Some people have worsening of their symptoms in the colder winter months. Many people report improvement in warmer months, climates, or with increased sunlight exposure.

Causes

The exact cause remains unknown. There may a combination of factors, including genetic predisposition and environmental factors. The immune system is thought to play a major role. Despite research over the past 30 years looking at many triggers, the “master switch” that turns on psoriasis is still a mystery.

Symptoms

Psoriasis typically looks like red or pink areas of thickened, raised, and dry skin. It classically affects areas over the elbows, knees, and scalp. Essentially any body area may be involved. It tends to be more common in areas of trauma, repeat rubbing, use, or abrasions.

Psoriasis has many different appearances. It may be small flattened bumps, large thick plaques of raised skin, red patches, and pink mildly dry skin to big flakes of dry skin that flake off.

There are several different types of psoriasis including psoriasis vulgaris (common type), guttate psoriasis (small, drop like spots), inverse psoriasis (in the folds like of the underarms, navel, and buttocks), and pustular psoriasis (liquid-filled yellowish small blisters).

Sometimes pulling of one of these small dry white flakes of skin causes a tiny blood spot on the skin. This is medically referred to as a special diagnostic sign in psoriasis called the Auspitz sign.

Genital lesions especially on the head of the penis are common. Psoriasis in moist areas like the navel or area between the buttocks (intergluteal folds) may look like flat red patches. These atypical appearances may be confused with other skin conditions like fungal infections, yeast infections, skin irritation, or bacterial Staph infections.

On the nails, it can look like very small pits (pinpoint depressions or white spots on the nail) or as larger yellowish-brown separations of the nail bed called “oil spots.” Nail psoriasis may be confused with and incorrectly diagnosed as a fungal nail infection.

On the scalp, it may look like severe dandruff with dry flakes and red areas of skin. It may be difficult to tell the difference between scalp psoriasis and seborrhea (dandruff). However, the treatment is often very similar for both conditions.

Treatment

Self-Care at Home

* Exposure to sunlight helps many people with psoriasis.

* Keeping the skin soft and moist is helpful. Apply heavy moisturizers after bathing.

* Do not use irritating cosmetics or soaps.

* Avoid scratching or itching that can cause bleeding or excessive irritation.

* Soaking in bath water with oil added and using moisturizers may help. Bath soaks with coal tar or other agents that remove scales and reduce the plaque may also help.

* Cortisone creams can reduce the itching of mild psoriasis and are available without a prescription.

* Some people use an ultraviolet B unit at home under a doctor’s supervision. A dermatologist may prescribe the unit and instruct the patient on home use, especially if it is difficult for the patient to get to the doctor’s office for phototherapy treatment.

Medical Treatment
Many treatments exist for psoriasis. However, the construction of an effective therapeutic regimen is not necessarily complicated.

There are 3 basic types of treatments for psoriasis: (1) topical therapy (drugs used on the skin), (2) phototherapy (light therapy), and (3) systemic therapy (drugs taken into the body). All of these treatments may be used alone or in combination.
