Scabies is an infection caused by a tiny mite that burrows under the skin usually on the hands, ankles, wrists or male genitalia.  They then live there and lay eggs.  Having these mites under the skin induces an allergic reaction which in turn causes a rash with extreme itching.  Scabies is more common in children but can occur at any age.  It is highly contagious and is spread through direct person to person contact.  The scabies mite cannot live long outside the body but sometimes it can be spread from contact with clothes, linen, etc if the infected person has just touched them.

Scabies

The rash usually develops between two to six weeks after the person has become infected.  The itching usually worsens at night or after a bath or shower when skin is hot. Sometimes burrow marks can be seen on the skin but most often they are hidden by marks caused by scratching or the rash itself.  These burrow marks are thin zigzag lines and are easier to see on hands or feet.

Scabies is treated with a scabicide which is a lotion or cream but it needs to be applied correctly or it may not work.  It needs to be applied twice with a week between each application and should be applied to cool dry skin.  The cream then should be washed off between eight and twenty four hours later.

Everyone in close contact with a person who has been diagnosed with scabies needs to be treated at the same time to make sure the infection has been completely erased.  All bed linen should be washed at a high temperature to make sure that all mites are killed.

People with personality disorders may have conditions such as not being able to live with others, not being able to maintain relationships with other people, finding it difficult to control emotions or upsetting other people when distressed.

Causes of personality disorders can include genetic makeup, mental or emotional state or brain problems. There are three types of personality disorder: suspicious, emotional and impulsive, and anxious.

Suspicious personality disorders are where the sufferer is often paranoid of other people, and finds it difficult to interact with others, preferring their own company instead.  The person with a suspicious personality disorder is often seen by others as strange or peculiar.

Emotional and impulsive personality disorders are where the sufferer is indifferent to other people’s feelings and can be quite aggressive.  They often find it difficult to control emotions and will do this spontaneously without thinking about the consequences.  Sufferers will also self harm if they feel really bad about themselves.

Anxious personality disorders are where the sufferer worries about everything.  They are very indecisive and worry constantly about doing the wrong thing.  Anxious sufferers are overly sensitive to criticism and can often feel worthless or incompetent.

There are therapies which can help such as psychotherapy or cognitive behavioral therapy.  There is also medication available to help with the different groups of personality disorders.  Antipsychotic drugs can help those in the suspicious group while antidepressants can help to relieve the symptoms of those in the emotional group.  There are also some antidepressants which have been shown to help those in the anxious group such as serotonin reuptake inhibitors (SSRI).

Personality Disorders

Drug allergies are adverse reactions to medication drugs and these reactions can be separated into three groups. First are those not actually related to the drug in question at all, but are coincidental and attributed to other mitigating factors associated with the illness or disease. Second are common predictable reactions like side effects related to taking other medication at the same time, or having an overdose. The third is unpredictable and uncommon reactions of which quite a few are allergic reactions that typically involve the immune system, being either immediate or delayed in reaction.

Allergic reactions can vary greatly from simple, slight rashes to very severe anaphylactic reactions of the immune system. Some drugs that can cause allergic reactions include heart drugs such as ACE inhibitors, antibiotics like penicillin, anesthetic drugs such as muscle relaxants, morphine, aspirin like drugs such as ibuprofen, chemotherapy drugs, antiseptics like iodine, vaccines such as tetanus, and colorings or preservatives in certain medications.

Reactions usually occur within one hour of taking the medication and can involve a measle-like rash that is very itchy. Some life threatening reactions may involve skin blistering with peeling accompanied by fever.

Common Allergic Reactions

Treatments of various drug allergic reactions involve the immediate withdrawal of the offending drug and then the administration of an antihistamine medicine. In severe allergic reactions, adrenaline and steroids may be used to save a life.
