Autoimmune Disorders
Aseptic meningitis has also been associated with autoimmune diseases. In particular, approximately 2% to 4% percent of patients with systemic lupus erythematosus may develop aseptic meningitis. In addition to malaise, fever, and headache, aseptic meningitis due to systemic lupus erythematosus may be accompanied by myelopathy, stroke, and decreased serum complement levels. The CSF typically has a neutrophilic pleocytosis.

Malignancy
Central nervous system tumors may manifest as acute or recurrent aseptic meningitis. This may result from direct invasion of the meninges with the tumor, and there may be involvement from leukemia, lymphoma, or metastatic tumors. A chemical meningitis, caused by lipid spillage from tumors such as craniopharyngiomas or pituitary adenomas, may also occur. Aseptic meningitis due to a malignancy may cause a very low glucose level. In addition, patients may present with focal neurologic findings. Neuroimaging is warranted. The prognosis is usually poor.

Mollaret’s Meningitis
Mollaret’s meningitis is a rare syndrome of recurrent acute meningitis. The symptoms of an individual episode will resolve spontaneously in 2 to 6 days but then recur in weeks to months. The disease is most common in young adults. The CSF demonstrates a mixed lymphocytic and neutrophilic pleocytosis. Early in an attack, large fragile mononuclear cells are seen, which have been demonstrated to be monocytes. Studies have shown links with HSV 1 and 2 as well as Epstein-Barr virus.

Skin picking has been described in the professional literature, particularly the dermatology literature, for many years, but it’s been little researched. Traditionally, this behavior has been considered a type of “neurotic excoriation,” a broad and antiquated term used for more than 100 years that doesn’t specify the cause of the picking or indicate treatment approaches. Not all people who pick their skin have BDD. Skin picking can occur as a symptom of other psychiatric disorders. In some cases, it’s simply a habit rather than a symptom of a disorder.
To determine whether picking is a symptom of BDD, ask the person why they pick. Do they pick to remove or minimize supposed defects or imperfections in their appearance, such as pimples, bumps, acne, or scars? If so, and if the other criteria for BDD are met, the picking behavior is a symptom of BDD. It’s often a clue to the diagnosis.
But often the picking is kept secret. Many people are very ashamed of this behavior and reluctant to reveal it to others. One adolescent who was referred to me because of his picking talked at length about other, more minor problems and didn’t mention his picking at all. When I finally asked him about it, he acknowledged that it was his major problem but that he’d been too embarrassed to bring it up.
But some people talk about it quite openly. One young woman I saw not only talked about it with others—she even picked her friends’ skin. “I can’t stand to see anyone with things on their face,” she explained. “I have to make their face smooth! When I see them, I pick off the little imperfections. They’re my friends, so they let me do it.” Another woman told me, “I look for anything to pick. I want to pick my friends’ skin because I pick my own and there’s nothing left. I especially like to peel other peoples’ backs when they’re sunburned.” She also liked to peel paint off walls, paper off jars, and dried glue off her hands.
People with BDD who pick are similar in many ways to those with BDD who don’t pick. But there are some interesting differences. Although skin concerns are common in both groups, those who pick are more likely than those who don’t to be concerned with their skin (close to 100% versus about 50%).
They’re also more likely to excessively groom and camouflage, perhaps because they sometimes do create actual skin defects that they feel they need to cover. People with BDD who pick their skin are also more likely than those who don’t pick to have actual skin defects, as opposed to none. Sometimes the minimal defects lead to the picking, and often they result from the picking. A vicious cycle can occur in which a minimal defect leads to picking behavior, which then creates more defects and more picking. Sometimes, skin defects caused by the picking are clearly present and noticeable.
People who pick their skin are also more likely to be treated by a dermatologist: approximately two-thirds versus fewer than one-third. Although dermatologic treatment is sometimes needed to treat the skin damage or infections that the picking can cause, it usually doesn’t decrease BDD symptoms (the skin-related preoccupations and associated picking).

Язвенная болезнь — это  хроническое рециди­вирующее заболевание, характеризующееся формировани­ем язвы в желудке или в двенадцатиперстной кишке вследствие расстройства общих и местных механизмов нервной и гормональной регуляции основных функций гастродуоденальной системы, нарушения трофики и протеолиза слизистой оболочки.
Язвенная болезнь широко распространена во всех странах мира и встречается у 2—3% взрослого населения, причем в 2 раза чаще у жителей города.
Мужчины, особенно молодого возраста, болеют язвенной болезнью в 4 раза чаще, чем женщины. Почти у каждой третьей женщины она возникает после наступле­ния менопаузы. Локализация язвы в двенадцатиперст­ной кишке характерна для подростков и мужчин молодого возраста, а в желудке — для женщин и мужчин среднего, пожилого и старческого возраста.
Основной причиной возникновения язвен­ной болезни является длительное или часто повторяю­щееся психоэмоциональное перенапряжение, преимущест­венно негативного характера (отрицательные эмоции, конфликтные ситуации, чувство постоянной тревоги, пере­утомление и т. д.). Психоэмоциональное перенапряже­ние наиболее характерно для людей молодого возраста, которые в этот период жизни завершают учебу в школе, поступают в высшие учебные заведения,  трудоустраиваются и т. д. Пред­располагающими факторами служат наследственная отягощенность, нарушения в питании (еда всухомятку, нерегулярный прием пищи, употребление грубой, острой пищи, плохое пережевывание ее при быстрой еде и болез­нях зубов, а также недостаточное содержание в пищевых
продуктах белков и витаминов, избыточное потребление углеводов), курение, употребление алкоголя.
Особенности клинического проявле­ния язвенной болезни в зависимости от локализации объясняются выраженностью секреторных и двигательных расстройств как в процессе пищеварения, так и в меж пищеварительном периоде, а также напряженностью и функциональной активностью того или иного отдела желудка и двенадцатиперстной кишки по обеспечению переваривания пищи и эвакуации ее в дистальные отделы желудочно-кишечного тракта.
Язвенная болезнь отличается часто возникающей изжогой и приступообраз­ной болью натощак, ночью, спустя 1,5—2 ч после еды. Стойко повышены кислотность и протеолитическая актив­ность желудочного сока, характерны рас­стройства желудка и двенадцатиперстной кишки. Неред­ко первым проявлением болезни бывает желудочно-кишечное кровотечение.

Tree pollens, grass pollens, and weed pollens cause allergic nasal symptoms in millions of people. Pollen is that part of plants that contains the male genetic material. The units in which this material is held are called pollen grains. Two walls surround the genetic material in each grain. The innermost wall, the intine, is very thin and fragile. The outer protective wall, the exine, is relatively thick and highly resistant to destruction. Pollen grains from different plants look as different from one another as do the plants from which they come, a fact which is best appreciated when the grains are stained with special chemicals and viewed under a microscope. This is, in fact, what is done when a pollen count is made. Stained pollen grains are beautiful, intricate structures. For example, ragweed pollen resembles a golf ball, oak pollen an intergalactic star-fighter, and cypress pollen, Рас Man.
Pollination is the term used to describe the transfer of pollen grains from the anther, the male organ of plants, to the stigma, the female organ of plants. Once transfer is completed, fertilization can take place. Surprisingly, only a small percentage of the thousands of plant pollens that exist are released into the air under circumstances sufficient to allow them to cause nasal allergy symptoms.
For a pollen to cause nasal allergies, it must meet four requirements:
- It must be produced in massive quantities.
- Its primary process of pollination must be via wind, not insects.
- It must be able to stimulate our immune system to produce an allergic response.
- We humans must be sufficiently exposed to the pollen to develop an allergy.

In order to be successfully wind pollinated, a plant and its pollen must have the following characteristics:
- A large number of pollen grains must be produced.
- The pollen must be aerodynamically sound, i.e., it must be of the right size, structure, and weight to be carried by the wind.
- The structure of the plant and its geographic location must favor the release of pollen into the wind.
- Pollen release during the season and during the day must be timed to optimize capture by the female organ.
- Like plants should be closely spaced to one another.

Treatment

In the great majority of children, no treatment is needed for thumb-sucking. In any case, treatment should generally not be contemplated before the age of 4 years. Thumb-sucking should be regarded as a normal behaviour up until this age, and treatment will be ineffective because the child does not yet have the cognitive capacity to co-operate.

Treatments that are sometimes advocated have not been shown to be effective. Some parents will use mittens, or hand restraints at night, or punish the child. These measures are harsh and unnecessary, and there is no evidence that they hasten the time when the child will stop the habit. Often the use of bitter-tasting nail polishes or similar solutions to paint on the child’s hands at night are advocated, but again with very little evidence that they do much good. These methods may work in the older child as a means of assisting him when he has already made a commitment with the parents to give up the habit.

All of these interventions may in fact have the opposite effect of what is intended.

By continuing to draw attention to the habit, parents may be unwittingly reinforcing it, and actually prolonging it.

In children of 4 years of age or older, where the continuation of thumb-sucking is embarrassing to the child, it may be worth considering a specific behaviour modification program for the child. This involves getting the child’s co-operation to stop the habit, and contracting with him to remind him when he does it. The child can help remind himself by drawing on his thumb, or putting a band-aid on it. Praise him when he does not suck his thumb, and reward him when he completes an agreed period of time (for example, a whole day) without sucking his thumb.

Prevention

There is no reliable way to prevent finger- and thumb-sucking, nor should you try to do so. It should be regarded as a developmentally normal part of childhood. To attempt interventions that are at best ineffective and at worse harsh and inappropriate for the child may actually prolong the habit. It may be helpful for you to consider providing other sources of comfort during periods of stress.

When to see your doctor

There are very few indications to seek medical help for this condition, because it is almost always transient and has no long lasting consequences. If the habit persists into the school years, the family dentist should be asked to review the child. Parents may want advice if they suspect that the habit is a manifestation of more serious underlying psychological problems, or if they are worried about other associated behaviours.

Thumb-sucking and finger-sucking are very common in young children. It is estimated that around half of all children will be thumb-suckers for several months or more during their toddler or preschool years. It is therefore considered a normal part of development, and despite parental protestations, rarely needs any active intervention.

Sucking of the fingers or thumb often starts during infancy. A young baby may initially bring his hand to his mouth accidentally, in the course of general movements of the upper limbs. In many babies this then becomes purposeful, as the baby derives comfort and pleasure from it. Indeed, thumb-sucking may be seen as a positive behaviour in infancy, and is regarded as part of the baby’s ability for self-regulation and self-comforting. Babies who can suck on their fingers are often more easily able to settle themselves without relying on parental involvement. This is especially helpful when going to sleep, or at times of distress.

Some children simply continue this habit that they have acquired in infancy. Others begin to suck on their fingers or thumb at some stage during the toddler period. For most children this is a normal developmental behaviour and it will soon pass. By the age of 4-5 years, only a few children are still sucking their thumb, although many will still revert to it at times of stress, tiredness or when going to bed.

There are rarely any serious or long-term complications of thumb-sucking. Many children will develop calluses on their thumb or fingers, which will often become misshapen. These effects are not long lasting and will return to normal soon after the child ceases the activity.

Infrequently there are more significant concerns. The main one appears to be a concern that the persistence of finger- or thumb-sucking beyond 4 or 5 years may interfere with the normal development of a child’s teeth, so that the teeth will grow unevenly. It is worthwhile asking the child’s dentist to check on this after the child prolonged thumb- or finger-sucking may interfere with normal speech development but it is likely that factors other than thumb-sucking are responsible for this.
