Eczema is not a disease per se, but is a name given collectively to a group of medical conditions, which can cause the skin to become inflamed and irritated. Atopic dermatitis is one of the most common types of eczema.

Causes

While the exact cause of eczema is not known, the most commonly attributed reason is an increasingly sensitive immune system. The overactive immune system produces antibodies, which cause these skin reactions. It is also noted that people with allergies including hay fever and asthma are more likely to develop eczema.

Other conditions which can lead to eczema include allergic dermatitis, irritant dermatitis, stasis dermatitis, scabies, fungal infections, xerotic dermatitis, lichen planus and scalp infections.

There is also a genetic predisposition, and children whose parents have had eczema are likely to develop eczema.

Symptoms

In most people, eczema is present in the form of small blisters, which are filled with fluid and can ooze. Gradually, there could be dryness, crusting, scaling and thickening of the skin with plaque formation. The most common symptom would be itching. The different types of eczema as noted above would have diagnostic features. For instance, when testing for irritant or contact dermatitis, there would be an irritant that is causing this. Stasis dermatitis would have circulatory issues and often affects the lower legs.

In fair-skinned people, these lesions begin as red and then turn brown. There also could be lightening of the affected skin area in people with slightly darker skin.

Diagnosis

For a trained medical eye, diagnosis of eczema is not a tough task. A complete physical examination may be done to assess the extent of eczema spread. Blood tests may be done to test for allergies. In very rare cases, a biopsy may also be required.

Treatment

The goal of treatment is to reduce itching and improve moisturization. Eczema, unless associated with an infection, is not contagious.

Using copious amounts of creams and lotions help in improving hydration and moisturization, as they are allowed to soak into the skin.

Topical steroids may be required if allergy is suspected. In most cases, hydrocortisone and corticosteroid creams are very effective.

Associated infections like scalp infections and fungal infections should also be treated with suitable products.

Immunomodulator creams like Elidel are useful by suppressing the immune system and preventing flare up of the allergic reactions.

Cold compresses may be used to relieve itching.

Prevention

Since there is a strong genetic component related to eczema, prevention is helpful.

Constantly keep the skin moist and hydrated by using moisturizers, especially during winters.

Avoid clothes and metals which can cause allergy- like wool, nickel, harsh soaps, detergents, etc.

Avoid or be careful about food items which are known to cause allergies.

Eczema - Causes, Symptoms and Treatments 

Knee replacement can be extremely painful. Previously, opioids or narcotics were administered for pain relief. But excessive addition of opioids is not exactly effective for controlling pain. 

Multimodal pain management has become an important part of the perioperative care of patients undergoing total joint replacement. The principle of multimodal therapy is to use interventions that target several different steps of the pain pathway, allowing more effective pain control with fewer side effects. Many different protocols have shown clinical benefit. The goal of this review is to provide a concise overview of the principles and results of multimodal pain management regimens as a practical guide for the management of joint arthroplasty patients.

Multimodal denotes administering two or more than two types of medications that work with different mechanisms. The following are the techniques used:

Pre-operative Femoral Nerve Block: Prior to the surgery, a catheter is placed beside the femoral nerve for blocking it. This nerve is located in the upper thigh. Medication is delivered through the catheter for the nerve to be numbed for 24 hours. Thus, pain signals to the brain are blocked. This method reduces the use of narcotics and the consequent side effects.

Patient Controlled Analgesia (PCA): This method is also known as  Pain Pump . An intravenous pump is used to administer pain relief medications, such as oxymorphone or morphine, after the surgery. The control button of the machine could be pressed, by the patient for 6 to 10 times per hour. The machine is used for two post-operative days.

Oral Medications: The oral medications include Non-Steroidal Anti-Inflammatory drugs or NSAID; such as Celebrex which is similar to aspirin, structurally. Alternatively, acetaminophen, such as Tylenol or its equivalent composition, can also be used.

Acetaminophen: It acts on the Central Prostaglandin Synthesis and relieves the patient of pain through multiple mechanisms.

Epidural Analgesia: It produces lower pain scores and involves less time for achieving physical therapy goals. However, this is subject to side effects such as dizziness, urinary retention and itchiness.

Gabapentinoids: These medications include membrane stabilizers such as Gabapentin and Pregabalin.

The objective of multimodal treatments is to provide quick relief to the patient and immediately so. Earlier the rehabilitation, more successful will be the knee replacement surgery.

Skin cancer is a condition with abnormal and cancerous skin growth. This often develops due to the over exposure of skin to the sun rays. The three main types of skin cancer include basal cell carcinoma, squamous cell carcinoma and melanoma. Skin cancer affects those areas of skin which remains sun-exposed, including ears, neck, chest, scalp, lips, face, hands, arm and legs. It can also develop on those areas of skin that are not exposed to sunlight like beneath toenails or fingernails, on palms and on genital area.

Here are some of the factors which increase your risks of getting skin cancer:

1.Fair complexion: Low levels of the pigment melanin in skin causes fair complexion. Fair- skinned individuals who have a history of hazel or blue eyes, repeated sunburns and people who have red or blond hair are highly susceptible to developing this form of cancer. Less pigment in skin makes an individual more vulnerable to skin damage from harmful UV radiation.
 
2. Excessive sun exposure: Exposure to the sun may lead to the development of skin cancer, if you don't protect your skin by sunscreen and clothing. Tanning beds and lamps may also increase the risk of developing this type of skin cancer.
                                            
3. High-altitude places: The exposure to sunlight is more intense in areas of high altitude and near the equator. Living at higher elevation also makes you more vulnerable to radiation because the sunlight is strongest there.

4. Moles: People with abnormal moles are at a higher risk of developing skin cancer. These moles are irregular in shape and are larger than normal moles.

5. Precancerous skin lesions: Your risk of developing skin cancer increases if you have skin lesion. These are scaly and rough patches that range from brown to dark pink in color. The most commonly affected areas are head, hands and face of fair-skinned people.

6. Weak immune system: Weak immune system caused by HIV or AIDS and immunosuppressant drugs that you take after an organ transplant may increase your risk of developing skin cancer.

Are You a Caffeine Addict? These 5 Yoga Asanas Will Help You Kick the Habit

A digestive system that is healthy and functions smoothly ensures sound health of both body and mind. If the digestive system faces any kind of interference, the body will be in trouble too. Regular exercising benefits the digestive system as well as the digestive process.

Keep on reading to understand the importance of exercise on digestion:

Boosts the blood circulation: Exercise is known to boost the blood flow in the body. Blood, being responsible for absorbing various nutrients from the digested food and then distributing them throughout the body, proper blood flow becomes necessary for the digestive system to function smoothly. The better the blood flow, the more efficient will be the digestive process. It also prevents risk of developing heartburn, gas, constipation, stomach cramps, etc.
Increases metabolism: Exercise also helps in boosting metabolism. As a result, it makes the food move through the digestive system more quickly. The quicker the passage of the food, the lesser the load or work done by the digestive system. When the food fails to pass quickly, it ends up sitting and rotting in the gastrointestinal tract, causing acidity and other stomach discomforts.
Helps in maintaining a digestive routine: Exercise also plays a crucial role in helping the body maintain a healthy digestive routine. Yes, it is through exercising that you can help your body to better utilize the nutrient-rich food that you are consuming. It is not only the fiber-rich foods or necessary water consumption, but also exercise that can help in establishing a routine for the body, such as regular bowel movement.
Makes the muscles strong: The role that regular exercising plays in strengthening the muscles around the intestines as well as the stomach say a lot about the relationship of exercise and smooth digestion. Just as the muscles of various parts of the body become strong, exercising strengthens the muscles involved with the digestion process. These muscles move the food through the intestines and stomach more easily and efficiently.
Keeps the mind relaxed and stress-free: Excessive stress can cause the oesophagus muscles to go into sudden convulsion or contraction, letting the stomach acid and the gastric secretions go back up the food pipe and interrupt the digestive process. The more stressed one is, the more hampered will be the process of digesting and absorbing nutrients. It is undoubtedly through regular exercising that both the mind and body can stay relaxed, and free from troubles caused by stress.
Before opting for any exercise, it's important that you consult a doctor first. This is because sometimes you may not be aware of your physical condition. If there are any underlying health problems, they could worsen by random, strenuous exercise.
