Hepatitis A is an infection of the liver caused by the hepatitis A virus. The well-respected World Health Organization (WHO) estimates that almost 1.5 million new cases of hepatitis A related illnesses occur each year worldwide, with a much higher number of people than this affected without showing any symptoms. The condition is more prevalent in the developing world where poverty and sanitation issues are rampant.

Hepatitis A is regarded as an acute infection as opposed to a chronic one, but in rare occurrences it can cause liver damage that is life threatening. The severity of symptoms in patients with the virus varies from individual to individual and whereas some may have no symptoms at all, others may develop symptoms to those similar of catching flu. As a rule, the older a person is, the more severe the infection, and therefore the symptoms, will be.

Some of the symptoms associated with hepatitis A include tiredness, weakness, fever, headache, nausea, loss of appetite, vomiting, dehydration and diarrhea. After a week or so of these symptoms, jaundice will appear. This occurs because in hepatitis infections, the liver is unable to remove a substance known as bilirubin from the blood. The skin and whites of the eyes become a yellow color because of the buildup of this pigment.

Hepatitis can be avoided be taking the following precautions: high levels of personal hygiene, drinking safe tap water and getting vaccinated against the disease if a visit to a high risk country is to be taken.

Nearly everybody alive goes through a state of feeling sad, or what we normally call depressed, but this usually goes away after a time. Individuals that happen to have a depressive disorder, or what we know as clinical depression, tend to find that this interferes with their daily lives and routines.

Depression in Men

To give depression an official description, the MediLexicon’s Medical Dictionary states that: depression is “a mental state or chronic mental disorder characterized by feelings of sadness, loneliness, despair, low self-esteem, and self-reproach; accompanying signs include psychomotor retardation (or less frequently agitation), withdrawal from social contact, and vegetative states such as loss of appetite and insomnia.”

Depression in Women

There are many types of depressive disorders and these include dysthymic disorder, major depressive disorder, psychotic depression, postpartum depression (which is normally referred to as postnatal depression), SAD (seasonal affective disorder) and bipolar disorder.

The symptoms and signs of depression are not clear-cut at all. Some symptoms that may be experienced by some individuals may not be had by others. Also, the severity of the illness all depends on the individual concerned and the type of depression they may have. Nevertheless, common symptoms experienced by sufferers of depression include the feeling of pessimism, sadness or anxiety; feelings of hopelessness, restlessness and irritability; loss of interest in pursuits, activities and sex, among other things; fatigue, loss of concentration and disturbed sleep; aches and pains, change of eating habits and sometimes even suicidal thoughts.

Depression and Heart Diseases

Tuberculosis is a condition which primarily affects the lungs.  The bacteria which cause tuberculosis are slow moving bacteria and a person who has been infected might not have any symptoms for months or years afterwards.  The infection can spread to other parts of the body such as the nervous system or the bones.  Symptoms of tuberculosis include a cough that won’t go away, night sweats and weight loss but most of the time the immune system will kill off the bacteria and there will be no symptoms.  Sometimes, if the immune system cannot kill the bacteria it will build up a defense to the infection and it will stay in the body but no symptoms will be experienced, however, sometimes the body just cannot fight the bacteria and the infection spreads to the lungs and becomes known as active tuberculosis.  It can happen that in cases where the infection has lain dormant in the body in can become active at a later date.

Tuberculosis

Tuberculosis was a major disease many years ago and resulted in many deaths, but the introduction of antibiotics and vaccinations helped to reduce this.  In recent years though, tuberculosis cases have been increasing again, especially in ethnic minorities who have come from areas where tuberculosis is still widespread. Areas where the disease is widespread include countries of Africa south of the Sahara desert, Eastern Europe, Central America, South East Asia, and Russia.

If tuberculosis is not treated it can be deadly as it can result in the person not being able to breath properly. Treatment with antibiotics for tuberculosis usually involves taking a course for at least six months.
