 Head lice  are insects that feed on the blood of your scalp. This condition usually affects children and is moderately contagious. Contrary to popular belief, head lice does not occur due to poor personal hygiene. 


The symptoms of head lice are:
1. Presence of lice on scalp: Lice are small insects that are usually hard to spot. But their infestation can be felt because you experience intense itching on the scalp. 


2. Itching: There will be intense itching on the scalp and the neck. This itching occurs due to the saliva secretion by the lice that the skin is allergic to. Usually, the itching starts after 3 to 6 weeks of infestation. 


3. Lice eggs: The lice eggs stick to the shafts of the hair. They are very hard to spot as they are small and well camouflaged. 


What can be the reasons behind their infestation
This condition is contagious; apart from direct contact with the scalp of an infected person, this condition can also spread if you happen to share the below mentioned items with an infected person:
1. Brushes 
2. Hats
3. Headphones
4. Towels
5. Pillows
6. Accessories for the hair


The treatments for hair lice are:
1. Over- the counter (OTC) products: OTC products are made from  pyrethrin , a compound extracted from the  chrysanthemum  flower.  Pyrethrin  works as an insecticidal compound and it is advised to use these medications only after washing your hair with a shampoo. Vinegar may also be used to loosen the nits from the hair shafts. 


2. Prescription medications: Certain medications can also be prescribed by the doctor, such as benzyl alcohol and lindane.


Certain home remedies for head lice include:
1. Essential oils: Apply oils such as Anise oil or tea tree on the scalp; these oils act as toxins for the lice.
2. Wet combing: This is a method wherein the wet hair is combed using a fine toothed comb to remove the nits and the lice. Repeat the procedure for 3-4 days every week.

Head Lice - How You can Treat Them?

28th July is considered to be World Hepatitis Day. Viral hepatitis can invade the human body in a variety of ways, but it is in your hands to prevent this infection from intruding your body and mess with your health. Hepatitis is a disease that takes a toll on the human liver. There are 5 different types of hepatitis from Hepatitis A to E, but there are ways you can take to prevent yourself against the same, such as:

Know how the Hepatitis spread: On the basis of the different types of Hepatitis, there are two main ways by which hepatitis gets its way from one person to another, contact with infected blood and body fluid as well as contact with the infected stool. It is important to note here that Hepatitis A and E are carried through the faeces of the affected individual. Also, a person may get infected with Hepatitis A and E even if you consume contaminated food and water. Hepatitis B, C along with D can also spread through the infected blood. 
Get the proper immunization: There are vaccines available all across the world to prevent spreading Hepatitis A and B. But it is crucial to point here that it is not possible to prevent Hepatitis C and D and sometimes Hepatitis E as well. But the Hepatitis C can be cured when the patient has received effective anti-viral medications. There are no vaccinations for Hepatitis D but the virus causing this infection requires Hepatitis B for survival. Therefore, getting vaccinated against Hepatitis B will help prevent the disease from affecting you.
Get the right precautions while travelling: When travelling, no one can tell whether you will get access to clean and purified water. Water contaminated with impurities can lead to Hepatitis A as well as E. You should take proper precautions and immunizations in the first place. If you are going to a place that doesn t have access to clean water, you should steer clear from ice cubes, running tap water, cut fruits and raw vegetables which may have been cleaned in the water with impurities.
By being aware and taking necessary precaution, getting affected by hepatitis can be prevented.

Alcoholism is a severe problem, which can make a person's life miserable and also make the society detest him. The aim of treatment for alcoholism is abstinence or staying away from alcohol use. The treatment of alcoholism can only begin when an alcoholic accepts the problem and realizes that he must get rid of the habit for his own good and the good of his loved ones.

There are three main stages in the treatment of alcoholism:

1. Detoxification: Detoxification is the first step required after a person stops using alcohol. The detox phase may include seizures, hallucinations and delirium tremens. The patient must be kept under proper observation.
2. Rehabilitation: This step includes proper counseling and medications to provide the person with skills and motivation to remain sober. This can be done by making him an inpatient or outpatient, depending on the condition of the patient.
3. Maintaining sobriety: This is the most important step where a person's self-will is tested. He needs to stay away from alcohol after getting out of rehabilitation for which he requires support. Meetings conducted by the Alcoholic Anonymous should be attended regularly by a recovering alcoholic.

For people in the early stage of alcoholism, discontinuing alcohol may cause several withdrawal symptoms such as poor sleep and anxiety. For long term alcoholics, severe withdrawal symptoms are experienced, which include shaking of the body, spasms, hallucinations and panic.

Medication
Several medicines may be required in the recovery period of an alcoholic.
Anti-anxiety medicines such as benzodiazepines are used for treating withdrawal symptoms like poor sleep. The medicines are usually used in the detoxification period. After this phase, they are discontinued.
For maintaining sobriety and to abstain from alcohol, several medicines are given to recovering alcoholics. A drug known as disulfiram is used after the completion of the detox period. This medicine reacts with alcohol metabolism and causes a person to vomit, become confused, have blurry vision and experience difficulties in breathing after consuming alcohol.

A medicine called naltrexone may be used for reducing alcohol craving. It can be prescribed even when a person drinks. It is given in the form of an injection. Antidepressants are also given to patients to reduce anxiety and depression.

Other ways to deal with alcoholism
Several other instructions must be strictly followed by a recovering alcoholic to avoid relapse. They are as follows:
1. People and places related to drinking should be avoided, and a person should make new nonalcoholic friends.
2. Support groups and AA meeting must be attended regularly for motivation.
3. Dependence on alcohol should be eliminated by starting different activities and getting involved in things.

Alcoholism is a severe problem, which may lead to death in case of extremities. Alcoholism can ruin a person's life, and proper measures must be taken to eliminate alcoholism.

Ways to Deal With Alcoholism

Peripheral vascular disease (PVD) is a circulation issue that affects the veins and blood vessels outside of the brain and heart. PVD commonly strikes the veins that supply blood to the arms, legs, and organs situated beneath the stomach. These are the veins that are located away from the heart. They are known as peripheral vessels.

In PVD, the width of the veins get limited. Narrowing is normally created by arteriosclerosis. Arteriosclerosis is a condition where plaque develops inside a vessel. It is additionally called 'solidifying of the arteries'. Plaque acts towards reducing the amount of blood and oxygen that is supplied to the arms and legs. As the plaque development advances, clumps may develop, which may further affect the vessel.

There are two main types of PVDs:

    Functional PVD: This doesn't include physical issues in the veins. It causes accidental side effects. Typically,these fits happen suddenly.
    Organic PVD: This includes changes in the vein structure. This sort of PVD causes irritation, tissue harm, and blockages.

The most well-known reasons for functional PVDs are as follows:

    Emotional stress
    Smoking
    Cold temperatures
    Operating Vibrating machinery

The common causes of such natural PVDs are given below:

    Smoking
    High circulatory strain
    Diabetes
    High cholesterol

The symptoms include the following:

    Cramps
    Achiness
    Fatigue
    Burning

Diagnosis:

PVD can be diagnosed using interventional radiology (IR).

IRis a sub-claim of radiology that gives an image-guided diagnosis, and if required, includes treatment of the organs as well.It has developed as a first-line treatment in the administration of PVD.

Advantages:

IR medications are for the most part less demanding for patients than surgery, since they include no surgical cut.They are less painful and have shorter stays at the hospital. By and large, the patients are discharged on the same day the procedure is done. This mainly includes angioplasty and stenting. The procedure is as follows:

    Utilising imaging for direction, the interventional radiologist puts a catheter through the femoral artery in the crotch to the blocked vein in the legs.
    At that point, the interventional radiologist expands a balloon to open the vein that is blocked.
    Sometimes it is opened with a tiny metallic cylinder called astent.
    This is a treatment that does not require surgery; only a scratch in the skin the extent of a pencil tip.

Alternative measure:

Angioplasty and stenting have totally replaced invasive surgical methods. Early trials have proven IR to be as successful as surgery for some blood vessel and artery impairments. Earlier, extensive clinical experience demonstrated that stenting and angioplasty are favoured as first-line treatments for more procedures all through the body .

Doctors as well as patients who have been through the same, believe that IR is much better for PVD than invasive surgery, since it reduces the risk of infection.

Diagnosing Peripheral Vascular Diseases With Interventional Radiology

A small piece of bone is known as a fragment and it is very common that an avulsion fracture also tends to damage the protrusions of bone to which the tendons attach. This basically means that the tendon or ligament will come away from the bone and it will take a small piece of bone with it. It is sometimes very hard to find out what type of injury you have and this is why knowing the causes and symptoms of an avulsion fracture are very helpful in determining exactly how severe the injury is. 

Here are the causes of an avulsion fracture:

Explosive landing: Athletes who tend to jump or land with great impact tend to get these most commonly. Therefore, it is crucial for your health that if you participate in such sports, you do follow the correct method of jumping.
Explosive extension: Similar to how an athlete landing ferociously can get an avulsion fracture, someone who is extending the legs very violently and explosively during an exercise can also get an avulsion fracture. This is because the bone getting extended could very well damage the protrusions to which the tendons are attached. 
Symptoms
These are the two main causes of an avulsion fracture. There are not many symptoms of an avulsion fracture. This is because an avulsion fracture can only be determined by an MRI or by an X-ray scan. Therefore it is nearly impossible to diagnose that you have an avulsion fracture without looking at the results of the tests performed on the part of your body. However, the way you got the fracture and especially the details of it are very good indications of whether you have an avulsion fracture or not.

Avulsion Fracture - Common Causes Behind it

Enlarged prostate surgery is a very common type of surgery that many have to undergo nowadays. An enlarged prostate causes many health problems including urinary tract obstructions and urinary tract infections. It may also lead to the passing of blood via urine. Thus, enlarged prostate must be treated as soon as possible as neglect may lead to prostate cancer and its associated health issues. There are various types of prostate surgeries that a doctor performs on his/her patients. However, of late, radical prostatectomy is the most popular of them all.

What is Radical Prostatectomy?

This process can be handled in two ways. Firstly, the prostate can be reached through an incision in the abdomen. This would help the doctor work with precision and carefully avoid all the other nerves and muscles in the area the operation take places. The prostate is examined and any nodule or lymph formed over it is carefully removed. The advantage of this surgery is that the patient is less likely to suffer from any erectile problems post- surgery. The second option would be to make an incision between the scrotum and the anus. This process is best for those who are obese. The surgery is performed quickly and there is less loss of blood. Furthermore, the healing time is less too.

How To Recover From The Surgery?

Like most other prostate operations, even in radical prostatectomy, you would have to wear a catheter till you recover completely. For a few days post the surgery your urine would be collected through a urine bag attached to the catheter. One might feel a little sore in his/her genitals after the surgery, but that is quite normal to occur. The soreness is caused due to the surgery and the incisions made and would heal in a matter of a few days. Interestingly, since the urethra plays an important role in this surgery, the catheter has to be in place for at least two to three weeks but the patient can be discharged after a two to three night stay at the hospital. It is advised that the patient takes ample rest. But this does not mean all rest and no work. In fact, it is seen that patients can walk a little and even go back to a normal diet within a week to ten days of the operation. But regular checkups, till the urethra is healed, are compulsory.

Hence, these are some of the recovery procedures after an enlarged prostate surgery. Such surgeries are quite common and heal quickly.
