How to prevent respiratory tract infection (cold)


I once granted an interview to a correspondent of Radio Nigeria, Ibadan, on the effects of the rainy season. I emphasised on cold as one of the effects of harmattan or rainy season but after the interview, the world common cold keep ringing in my ears.

Common cold is common and it occurs throughout the years even though there are increased cases during harmattan and rainy season due to the harsh weather. It is the most frequently occurring illness all over the world, and it is a leading cause of visits to doctors and missed days from school and work. 

It is a self-limited contagious illness that can be caused by a number of different types of viruses.
Children in preschool and elementary school can have cold monthly while adolescents and adults typically have two to four colds per year.

Flu has been used  interchangeably with the common cold but they are not the same thing. The ‘flu’, which is also known as influenza, is caused by a different virus (influenza A or B). Influenza is much more serious than a cold and can be life-threatening.

 A cold is a milder respiratory illness than the flu. While cold symptoms can make one feel bad for a few days, flu symptoms can make one quite ill for a few days to weeks.
The flu can also result in serious health problems such as pneumonia and hospitalisations. Flu can also be prevented by Influenza (Flu) vaccine.

Transmission

The common cold virus is typically transmitted via air- borne droplets, direct contact with infected nasal secretions, hand-to-hand , hand-to-surface or contaminated objects.
Transmission is common in daycare and at school due to the proximity of many children with little immunity and frequently poor hygiene. These infections are then brought home to other members of the family. Some of the viruses that cause the common colds are seasonal, occurring more frequently during cold or wet weather. 

Poor immune function, stress, insufficient sleep and malnutrition  are also a risk factor for disease.
Breast feeding decreases the risk of lower respiratory tract infections among other diseases and it is recommended that breast feeding be continued when an infant has a cold.

Symptoms

Cold symptoms usually last five to seven days. During the first three days, it is very contagious. This means you can pass the cold to others. So stay at home and get some much-needed rest.

Cold symptoms usually begin with a sore throat, which usually goes away after a day or two. Nasal symptoms such as runny nose, sneezing, congestion, cough and headache often occur by the fourth and fifth days.

Fever is uncommon in adults, but a slight fever is possible. Children are more likely to have a fever with a cold. A dry cough can last up to two weeks even after you feel better.
Coloured discharge from the nose is a normal part of your immune response and doesn’t mean that you need antibiotics.

Treatment
  • No cure for the common cold exists, but the symptoms can be treated.
  • Paracetamol is effective for fever and mild pain, and is a common ingredient in many ‘cold and flu’ medicines.
  • Nasal decongestants can help to ease a blocked nose. They work in the nose by reducing blood flow and swelling, making it easier to breathe.
  • Sore throats can be relieved with gargling salt water; licking throat lozenges, other home remedies are sipping a warm drink with lemon and honey and eating garlic.
  • Antibiotics do not help treat colds and overuse may lead to resistance, making them less effective when they are needed.
  • They can also cause many unwanted side effects such as allergic reactions, diarrhoea and thrush. However, if cold symptoms do not seem to be improving after a week, you may have a bacterial infection, which means you may need the antibiotics.
Prevention
  • The most important prevention measure for preventing colds and flu is frequent hand washing. Hand washing by rubbing the hands with warm soapy water for at least 20 seconds or alcohol-based hand sanitiser and hand wipes helps to slough germs off the skin.
  • Teach everyone in the household to cough or sneeze into a tissue. If you can’t reach a tissue on time, cough or sneeze into the crook of your arm.
  • Avoid sharing utensils, drinking glasses, washcloths, towels and other items that might harbour germs with anyone who has a cold or fever.
  • Avoid close, prolonged contact with anyone who has a cold or other communicable infection.
In conclusion, let’s take the preventive measures to reduce the spread of cold especially during this rainy season.

Know the diseases linked to frequent urination in men

Many men who read my last piece in this column, titled, ‘Why women urinate frequently ’’, have asked for a similar piece.
They want to know and I put together this article to address the issue in men. I hope to put up a piece on why children urinate frequently too.
If you need to go to the toilet more than usual, it’s known as frequent urination. It usually involves going to the loo more than eight times a day. You may also wake up frequently at night needing to wee (nocturia). Symptoms often include bladder discomfort and a strong, urgent need to wee due to an overactive bladder.
Causes
There are many potential causes of urinary frequency. They range from minor and very easily treated conditions to more serious diseases. Not all causes of urinary frequency are caused by bladder dysfunction. Occasionally this is related to the amount or type of fluid consumed.
Caffeine and alcohol can cause frequent urination in some patients. One of the more common causes of urinary frequency is a urinary tract infection. Sometimes urinary frequency can be caused by stones in the urinary tract. Bladder obstruction due to an enlarged prostate can lead to urinary frequency, just as the frequency can be caused by tumours in the bladder.
Urinary frequency is occasionally related to neurologic conditions. Stroke, spinal cord injuries and multiple sclerosis are often associated with frequent urination. Often, urinary frequency is caused by abnormal pelvic nerve function and coordination.
Urinary frequency can be associated with some serious diseases. Diabetes mellitus and siabetes insipidus can cause frequent urination. Diabetes mellitus can lead to high-volume frequent urination.
Diagnosis
A thorough history and physical examination can often give insight to the cause of frequency. A urine test/analysis is necessary to check for the presence of glucose, protein, ketones, or signs of infection.
Occasionally checking how much urine is left behind after urination is performed with a bladder scanner. In some cases, looking in the bladder with a telescope (cystoscopy) is performed to ensure there is no evidence of tumors in the bladder wall. Blood tests are also used to assess kidney function and the presence of glucose. Neurological tests can establish the presence of nerve damage or a nerve disorder.
Treatment
There are many treatment options for urinary frequency. Not all patients need treatment. If the frequency is not bothersome, no treatment is necessary. In some cases simple dietary modification can improve frequent urination. This may involve limiting certain foods and drinks such as alcohol, caffeine, tomato-based products, chocolate, artificial sweeteners, spicy foods.
Excess weight can put unnecessary pressure on your bladder. A healthy, low-fat diet and regular exercise can help to reduce weight and decrease frequent urination or incontinence. Treatment of bladder infections with antibiotics may alleviate the frequency. If a patient has medical conditions such as diabetes and prostrate gland disorders, the urinary frequency can improve as the disease process is better controlled. In some cases, treatment may simply involve altering your daily habits, including limiting your fluid intake, especially before bedtime, being familiar with side effects of any medication you take.
Depending on the root cause of frequent urination, other non-surgical treatment may include pelvic floor exercises These exercises can strengthen the muscles that support the bladder and urethra. Exercising for just five minutes, three times a day, can help you to control your bladder more effectively.
Bladder retraining: This involves learning techniques that help to retrain your bladder, and gradually increase the time between visits to the toilet. It usually takes about six to 12 weeks to retrain yourself to hold urine longer and to pass urine less frequently. There are medications that can slow down an overactive bladder. If these steps are not effective then medication, or sometimes surgical treatment, may be recommended depending on the underlying cause of the problem.
Prevention: While not all urological problems or disorders can be avoided, there are lifestyle choices one can make every day to help to reduce the chances of developing a serious problem.
Some of these include avoiding excess alcohol or caffeine, avoiding certain medications, i.e. diuretics,. Do not smoke. Engage in moderate physical activity and maintain a healthy weight.
In conclusion, when a man experiences urinary symptoms such as frequent urination, he should talk with a doctor without delay. This or other symptoms may be a sign of a more serious problem that needs attention

Why women urinate frequently


A woman, a beer parlour owner, who was passing urine frequently, was accused by husband of taking too much of what she sells. The argument got so heated that he forced her to go for a test. Lo and behold, the result had no traces of alcohol, rather it was a case of frequent urination due to an overactive bladder! Urination is the body’s way of getting rid of excess water, as well as wastes. While this is an important function for survival, its frequency can interfere with a woman’s quality of life.
Symptoms
Frequent trips to the bathroom, not sleeping through the night or refraining from going out for fear that they will leak urine, are often familiar to women who experience frequent urination.
A change in the colour of urine (red, pink, or cola-coloured),  a sudden and strong urge to urinate, difficulty in emptying the bladder,  urinary incontinence and painful urination are all indications of bladder control problems in women.
Causes and risk factors
Diets: Caffeine intake through coffee, tea, alcohol intake and certain soft drinks
Lifestyle: Obesity (excess weight) can place extra pressure on the bladder. The result can be weaker pelvic floor muscles and a need to urinate more frequently.
Pregnancy: Frequent urination is common with pregnancy. The growing uterus can place extra pressure on the bladder during pregnancy. As a result, a woman may have to go to the bathroom more frequently.
Menopause: It can also affect bladder control. When women no longer have their periods, their bodies stop making estrogen.
Medical: Bladder stones, diabetes, cystitis (a chronic, inflammatory disorder of the bladder),  low  estrogen levels, urinary tract infection and a weak pelvic floor organ.
Childbirth: Childbirth can weaken the pelvic floor muscles and damage the nerves in the bladder. Sometimes a woman may not experience problems with bladder control immediately after giving birth, but she may experience symptoms years later.
Complications
Complications associated with urinary frequency often depend on the condition’s underlying cause, which would be urinary tract infection, pyelonephritis, renal failure  or damaged kidneys.
If urinary frequency occurs on its own with no immediate treatable illness, it can affect a woman’s quality of life. A woman may not be able to sleep well due to having to wake up to go to the bathroom very often. She may also refrain from social events for fear of having to go to the bathroom too frequently. These complications can all influence a woman’s sense of well-being.
Diagnosis
A doctor may take a urine sample for evaluation. A laboratory can identify the presence of white or red blood cells, as well as other compounds that should not be present in the urine that could indicate an underlying infection.
Tests for blood sugar are mandatory, the urine can also be tested for the presence of glucose.
Abdominal scans may be done, while taking blood samples for electrolytes to rule out complications is also necessary.
Other tests may include cystometry or the measure of pressure in the bladder, or cystoscopy, which involves using special instruments to look inside the urethra and bladder. Other diagnostic methods may depend upon a woman’s specific symptoms.
Treatments and preventive techniques
There are lifestyle and medical means to treat frequent urination so that a woman does not have to suffer with the symptoms.
Lifestyle modifications: Avoiding foods and drinks known to irritate the bladder can help a woman experience fewer episodes of urination. Examples include avoiding caffeine, alcohol, carbonated beverages, chocolate, artificial sweeteners, spicy foods and alcoholic drinks.
Adjusting patterns of fluid intake: Avoiding drinking too much water before bedtime can reduce the likelihood of waking up at night to go to the bathroom.
Bladder retraining: Bladder retraining is another method to reduce the amount of times a woman goes to the bathroom per day. To accomplish this, she will work on a regular schedule instead of always waiting until she feels the need to urinate.
Antibiotics: If a urinary tract infection is causing a woman’s frequent urination, taking antibiotics to cure the infection may help. Other treatments and preventive techniques for frequent urination that is not due to infection include:
In addition to these methods, medications can be prescribed that reduce bladder spasms and encourage relaxation of the bladder. Sometimes a doctor will recommend injections which can reduce the incidence of bladder spasms.
In conclusion, painful urination or pelvic pains along with frequent urination, are also causes for concern. A woman should also see her doctor any time that she experiences symptoms make her uncomfortable or interfere with her quality of life.
