Eczema as risk factor of itching symptom

Itchy rash usually on cheeks or chin, but may show up on the head, trunk, back of arms, or front of legs, but usually not in diaper area; dry, thickened patches of scaly skin or sometimes tiny red bumps that may ooze; patches may be symmetrical. Most common in families with history of allergies or asthma.

Winter Itch Diagnosis

Winter itch (sometimes spelled winteritch) is a common condition caused by dryness of the skin (integument). Xenoderma is another term for skin dryness. Skin becomes dry in winter due to the low relative humidity of cold air which has been heated. A tentative diagnosis of winter itch can be made if the itch (pruritis) occurs only in cold weather. Itching of skin can be caused by a variety of other medical conditions, so consultation with a medical professional is advised.

What can be done to prevent or to reduce swimmer’s itch?

1. avoid swimming for long periods in shallow water 2. avoid swimming in areas where swimmer's itch is a problem and where there is an onshore wind 3. towel off immediately after leaving the water may help reducing swimmer's itch caused by cercariae of some species that enter only as the water dries on the skin 4. post appropriate signs on beaches where swimmer's itch is an annual problem 5. do not encourage birds to stay in your area by feeding them 6. avoid placing rip-rap on your shore. This provides an ...

How do you determine which birds are carrying the schistosomes that are causing swimmer’s itch on a particular lake?

Birds can be checked for avian schistosomes by hatching the miracidia from parasite eggs in the hosts' feces. If hatch-year (young birds) that can't fly are positive for avian schistosomes, then it must be concluded that they contacted the parasite on that specific lake. Not only can the bird species of dermatitis-producing parasite be isolated, but it is possible to determine the level of infection. This is done by weighing the fecal content and then counting the number of miracidia that hatch from one gra...

Why may swimmer’s itch be a problem one year but not the next?

The following are factors that may determine whether swimmer's itch may be a problem on a specific lake at a given time: distribution and number of snails that can serve as intermediate hosts distribution and number of bird hosts that can serve as hosts for the adult worm wind direction water currents number of hours that people stay in the water time of day sensitivity of the individual to swimmer's itch. All of these factors can change on an annual basis.

What is the life cycle of swimmer’s itch causing parasites?

The causative agent for swimmer's itch is the larval, free-living and aquatic stage of a group of flatworms that are called schistosomes. Most of species that cause swimmer's itch use bird hosts for the adult parasite and aquatic snails as intermediate hosts for the larval stages. The life history of the dermatitis-producing worms is cyclic. Eggs released from the adult worms that reside in the blood vessels (usually veins around the intestine) of the bird host, make their way into the digestive tract of th...

Why do children often develop the most severe cases of swimmer’s itch?

They usually swim more regularly, their skin may be more sensitive, and young children have a tendency to stay near the water's edge. It appears that cercariae may concentrate near the shoreline.

Will I get more sinus infections in the future?

Once your sinus infection has been treated, it is important to try to prevent future sinus infections, but they often occur. It is important to provide adequate treatment of colds and allergies in order to try to prevent blockage of the sinuses. We commonly suggest that people start many of the medications, with the exception of antibiotics, at the first sign of development of cold symptoms. You should talk with your doctor about that possibility. The more frequently that sinus infections occur, the more li...

Can sinus problems be due to an immune deficiency?

It is unusual, but sometimes sinus infections are caused by immune problems. In patients who have persistent sinus infections, it is important to have the immune system evaluated by an allergist/immunologist, especially before surgery is done. You may need to have allergy tests done, as well as tests done to make sure that you can form antibodies normally to common bacteria. Rarely, it can be due to AIDS, but don't jump to conclusions: 99.9% of people with sinusitis don't have AIDS.

What other problems happen as a result of sinusitis?

I have seen patients with problems like hives which wouldn't get better, they had no other symptoms. The hives got better immediately with treatment of sinusitis. I was amazed. Sinus problems may also cause all kinds of allergies to worsen (it seems that sinusitis turns on the immune system) and can cause problems with asthma, intestinal symptoms, and a wide variety of other medical problems. I have had patients who have toothaches and have numerous dental procedures to no avail. "Migraines" are an especial...

What if the surgery doesn’t help for sinus surgery ?

First, be patient, recovery from surgery takes weeks (occasionally months). If you aren't better at that point then there are many possibilities including allergies, immune problems, fungal infection of the sinuses, scarring from the original surgery, sinusitis involving sinuses other than those originally operated on, etc. If you have these kinds of problems, it is critical that you see someone who is well experienced with medical treatment of patients after surgery.

How is treatment different after surgery?

It doesn't mean that you won't get sinusitis any more, but it is often easier to treat. Surgery is not meant to cure the disease. Once the sinuses have been opened up by surgery, it is possible to wash out the sinuses if necessary , and as a result, sometimes oral antibiotics don't have to be used. It is often possible to do an endoscopy and find out exactly where the cause of the problem is, since it is possible to examine the inside of the sinuses once surgery has been done. Elsewhere on this website, the...

How long is the recovery after surgery?

Generally, patients will remain in the hospital just for the day of the operation, but sometimes overnight. Patients are usually out of work for 1-2 weeks. Full recovery may take six weeks, although for periods of six months to a year patients may become more sensitive to infection. The surgeon will typically remove crusting on a regular basis from the nose to prevent scarring from occurring. Packing is often not placed nowadays, so that the removal of crusting isn't usually that uncomfortable. There will b...

What is done if I have to have sinus surgery?

You should first understand that I am not a surgeon, so this is from the perspective of someone who has seen the surgery, and had the surgery done, but who doesn't do the surgery himself. The surgery, called functional endoscopic sinus surgery (FESS), may be done either under local anesthesia or general anesthesia. Many very experienced sinus surgeons prefer to use local anesthesia. The operation generally takes approximately 2-3 hours. During that period of time, the ear, nose and throat doctor will do any...
