The common cold and flu are two very different viruses that share very similar symptoms. The common cold is a self-limiting upper respiratory tract infection and it is caused by the rhinovirus, coronavirus or the adenovirus. It usually resolves within 7-10 days. The flu is caused by the influenza virus and usually presents with headaches, myalgia, fever and body aches. There is no place for antibiotic usage in colds and flu and there is no clinical evidence which suggests that using antibiotics alters the course of the disease or prevents secondary infection. Treatment is mainly symptomatic and includes many over the counter medicines for symptomatic relief like Adco Flupain or Corenza C, antivirals and herbal treatment. [ABSTRACT FROM AUTHOR]

Rotavirus disease is known to be the most important cause of severe gastroenteritis in children worldwide. It affects nearly all children by the age of five years. Transmission of the virus occurs mainly through the faecal-oral route. Complications that are associated with rotavirus infection include malnutrition and dehydration. These may have a fatal outcome. Vaccination against rotavirus disease is the most efficient way to protect children against rotavirus infection and can save many lives. Primarily, treatment is aimed at rehydration to replace fluid and electrolyte losses. [ABSTRACT FROM AUTHOR]

Vitamins are either fat- or water-soluble micronutrients that are derived from a healthy, well-balanced diet. The B-complex vitamins are well-known examples of water-soluble nutrients that are readily absorbed from a healthy gut, and easily eliminated via renal excretion. They are required for their vital physiological functions and are significant contributors to the maintenance of optimal health. Multiple B-vitamin deficiencies are quite common. Therefore, a balanced diet, including a full spectrum of B vitamins, is usually needed when any of them are found to be deficient. Conversely, their therapeutic value is limited to supplementation during states of deficiency since they have no additional benefits in the presence of an adequate dietary intake. In general, their active supplementation should only be used to correct deficiencies. This article provides an overview of B-complex vitamin deficiencies and their supplementation.

Allergic diseases are increasing all over the world, now affecting up to 40% of the population. The most frequently occurring allergic conditions include allergic rhinitis (hay fever), chronic sinusitis, atopic dermatitis, and chronic urticaria. The literature suggests that second-generation histamine 1 (H1) antihistamines are the preferred first-line therapy for most chronic allergic conditions, including allergic rhinitis and chronic urticaria. Patients taking these antihistamines report little to no adverse effects with long-term continuous treatment. Second-generation H1-antihistamines have been shown to exert an anti-inflammatory effect, and continuous administration may improve their efficacy. [ABSTRACT FROM AUTHOR]

This article provides an overview of the changes that have taken place in the diagnosis and management of hypertension over the past decade. Hypertension remains a very common condition seen in South Africa. The approach to the management of hypertension includes necessary lifestyle modifications and a decisive, stepwise escalation process in the pharmacotherapeutic management thereof. Thiazide diuretics are still being promoted by most guidelines to be the initial (first-line) drug of choice, with the addition of other suitable antihypertensive agents, if necessary, and according to any relevant co-morbid conditions.

Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) pose a significant burden to the healthcare system annually. A positive impact on, and a reduction, in the mortality rate can be achieved through an understanding of the most common microorganisms that cause these two closely-associated conditions, identifying the associated risk factors and co-morbidities, and making a timely diagnosis. With the correct understanding of these conditions, proper preventative strategies can be implemented and treatment provided according to the severity of the specific condition in question. Better outcomes for infected individuals are likely to result from newer strategies involving novel antibiotics, as well as new approaches to the use of older antibiotics for different purposes. This article provides a general overview of the nature and management of HAP and VAP. [ABSTRACT FROM AUTHOR]

Allergic disease decreases the daily quality of life of many people, and can increase the number of working days lost owing to sick leave. Associated symptoms with allergic disease depend on the origin of the disease, and can either be allergic, non-allergic and purulent, or can cause rhinitis as a result of a common cold. Treatment depends on the origin of the rhinitis. However, an antihistamine is indicated in most instances. Combination treatment includes sympathomimetic drugs (either local or systemic) and corticosteroid medication (when indicated, and in most instances, used locally). The article provides an overview of the nature and the management of allergic disease and the histamine 1 antihistamines. [ABSTRACT FROM AUTHOR]
