Viral upper respiratory infections

The cough may be caused by infections of different origins, from ordinary trivial viral upper respiratory infections to serious bacterial pneumonias including tuberculosis. 

Many patients receive lengthy courses of antibiotics that probably should not have been started. More than half of courses of antimicrobial chemotherapy are inappropriate. Influenza pneumonia and viral upper respiratory infections, for example, are impervious to assault by antibiotics, although many patients with these illnesses receive such antibiotics. Of course, influenza may be complicated by postinfluenzal staphylococcal pneumonia, for which antibiotics are indicated. Careful sequential evaluation of seriously ill patients for whom antibiotics are deferred is as important as in patients for whom antibiotics are prescribed. 

Throughout the 3 weeks 1 was there, we only had one small outbreak of diarrhea, which was contained within 3 days, and some small outbreaks of viral upper respiratory infections. This was achieved by nearly daily reminders in loudspeaker announcements that clean hands would be about the only way to stop disease spread, and that residents had to be personally responsible and pretty determined about seeking hand cleansing opportunities to keep us all healthy. They rose to the occasion.

Viral upper respiratory infections are significant sources of morbidity and account for 75% of all illnesses among children (3). Although the symptoms can be mild and self-limiting, they can also increase the predisposition to secondary bacterial infections, which can occur in as many as 5% of cases (4). 

Acute bacterial otitis media usually follows a viral upper respiratory tract infection that causes eustachian tube dysfunction and mucosal swelling in the middle ear. 

Adenoviral vectors are considered the most versatile and easily manipulated viral vectors for delivering genes, and over 50 identified serotypes of human adenovims are known belonging to six species. They infect the respiratory tract in normal populations, resulting in upper respiratory infection, but their effects are self-limited.

Acute cough is a common symptom associated with viral upper respiratory tract infections (URTIs) such as the common cold (see Chapter 21), and pharmacists are most frequently asked for advice and treatment for coughs from this cause. However, cough is a symptom of many conditions, most of which require referral to a doctor for further investigation. Pharmacists must be able to distinguish between a cough from a trivial condition and one from a potentially more serious cause and make appropriate referrals. 

It is not uncommon for coughs to persist for several weeks in children after a chest infection. However, the child may have an allergy and be developing asthma. If so, the most likely cause is house dust mite or dander (fur particles) from a household pet. You should ask the mother for further clues for example is he worse in any particular room of the house, or worse after dust is raised, say with vacuuming or with changing the bed sheets Do any other family members suffer from asthma, hayfever or eczema On the other hand the child may have another viral upper respiratory tract infection, but as you are unable to decide the cause you should advise the mother to take him back to the doctor. 

Viral infections are primarily responsible for exacerbations of asthma. Viral upper respiratory tract infections are a major precipitant of acute asthma in children, being involved in up to 20% to 40% of acute episodes. Infants are particularly susceptible to airways obstruction and wheezing with viral infections because of their small airways. The most common cause of exacerbations in both children and adults is the common rhinovirus." Other viruses isolated include respiratory syncytial virus (RSV), parainfluenza virus, coronavirus, and influenza viruses. The inflammatory response to viral infection is thought to be associated directly with the increasing BHR. Certain viruses (RSV and parainfluenza virus) are capable of inducing spe-... 

Sinusitis is diagnosed more frequently in children than in adults. Typical clinical presentation and diagnosis of bacterial sinusitis are illustrated in Table 107-4. Between 5% and 13% of viral upper respiratory tract infections in children are complicated by bacte-... 

Tincture Use fresh herb in flower 1 2 with 95 percent alcohol, use 20 to 40 drops up to 3 times day in hot water. Dry herb 1 5 with 60 percent alcohol, use 30 to 50 drops in hot water up to 3 times a day. In acute viral or bacterial upper respiratory infections, use 10 drops of tincture in hot water every half hour up to 6 times a day. In chronic conditions when the acute stage has passed but there is continued chronic fatigue and relapse, use 10 drops of tincture in hot water 4 times a day. 

Many herbs can be harvested and eaten in whole form. Wormwood root, a prime example, can be used for sore throats and upper respiratory infections of both viral and bacterial origin. It is very strong, and a bit of fresh root can be carried in the pocket and a little eaten whenever needed. Sometimes a combination of whole herbs and tinctured herbs works well in this instance, wormwood root with a supportive combination of echinacea, red root, and licorice tincture for upper respiratory infections. 

A viral upper respiratory tract infection (URTl) induces transient cough receptor hyperresponsiveness to capsaicin (O Connell et al. 1996) thus, subjects in whom baseline cough reflex sensitivity measurements will be required should be excluded from enrolment in clinical trials if symptoms consistent with URTl have occurred within the previous 4 weeks.

The most common adverse effect with omalizumab is injection-site reaction, reported in 45% of patients in clinical trials. Other adverse effects include viral and upper respiratory tract infections, sinusitis, headache, and pharyngitis. Rare cases of malignant neoplasms and anaphylaxis were reported during clinical trials of omalizumab in asthma. Patients should be monitored for at least 2 hours following the injection so that anaphylaxis and/or injection-site reactions may be managed.25... 

Upper respiratory tract infection (URI) is a term that refers to various upper airway infections, including otitis media, sinusitis, pharyngitis, and rhinitis. Most URIs are viral and often selflimited. Over 1 billion viral URIs occur annually in the United States, resulting in millions of physician office visits each year.1 Excessive antibiotic use for URIs has contributed to the significant development of bacterial resistance. Guidelines have been established to reduce inappropriate antibiotic use for viral URIs.2 This chapter will focus on acute otitis media, sinusitis, and pharyngitis because they are frequently caused by bacteria and require appropriate antibiotic therapy to minimize complications.

In rural regions with maximal pesticide exposure, children more often suffer the following illnesses before the age of 14 [A109] iron-deficit anemias (10 times more often in Turkmenia, 4 times in Armenia, 2.5 times in Azerbaijan, 2 times in Uzbekistan, and 1.4 times in Moldavia) active tuberculosis (2 times in Moldavia, 2.3 times in Kirgizia, 1.6 times in Armenia and Azerbaijan) viral hepatitis (23.7 times in Turkmenia, 2.4 times in Armenia, 2 times in Azerbaijan, 1.2 times in Kirgizia) and acute upper respiratory tract infections (21 times in Turkmenia, 1.4 times in Kirgizia). 

A number of cells, including cytotoxic T lymphocytes, NK cells, and mononuclear phagocytic cells, are endowed with cytotoxic abilities and thus mediate important immunosurveillance mechanisms against neoplastic cells and viral infections. In immune-compromised hosts, a correlation has been observed between low NK cell activity and morbidity [22-25] or the incidence and severity of upper respiratory tract infections [24],...
