Acrodermatitis Chronica - Treatment and Prevention


Acrodermatitis chronica atrophicans (ACA) also known as Pick-Herxheimer disease. ACA is not limited to any one nationality or race. It is much more frequent in whites than in other races, probably because of a far higher exposure to ticks transmitting B afzelii. ACA is a dermatological condition that takes a chronically progressive course and finally leads to a widespread atrophy of the skin. Involvement of the peripheral nervous system is often observed, specifically polyneuropathy. About 5-10% of patients with ACA develop sclerodermalike plaques. Anetodermalike skin lesions can be seen concomitant with ACA.ACA in its early inflammatory edematous stage shows a dense, patchy perivascular and periappendiceal dermal infiltrate of lymphocytes, histiocytes, and plasma cells.

Collagen bundles become swollen and homogeneous and are split by mucinous deposition. Early stages of the disease show superficial and deep inflammatory cellular infiltrate in the dermis. ACA shows atrophy of collagen and elastic tissue as well as hypertrophic basophilic elastic tissue; whereas in morphea, sclerosis and polarizing elastic tissue are prominent. The acute inflammatory stage of ACA is treated adequately. The therapeutic outcome is difficult to assess in patients with the chronic atrophic phase, in which many changes are only partially reversible. Physicians should use serologic and histologic examination to confirm the diagnosis of ACA. Treatment consists of antibiotics including doxycycline and penicillin for up to four weeks in the acute case.

Acrodermatitis Chronica - Prevention and Treatment Tips

1. Antibiotics including doxycycline and penicillin for up to four weeks in the acute case.

2. Burgdorferi flagellum a needed reference antigen for growing routine serology in Lyme borreliosis.

3. Leukocytoclastic vasculitis or vessel occlusion may be seen in some cases.

Milium Treatment and Prevention Tips


Colloid milium is more common in fair-skinned individuals. Colloid has a distinct electron microscopic appearance, which helps to distinguish it from amyloid. Colloid milium (CM) is a rare cutaneous deposition disease with at least 3 distinct subtypes. Colloid milium (CM) is a rare cutaneous deposition disorder characterized by the presence of multiple dome-shaped. Colloid milium is a degenerative condition linked to excessive sun exposure and possibly exposure to petroleum products and hydroquinone. Colloid milium is a rare condition characterized by (1) the presence of multiple, dome-shaped, amber- or flesh-colored papules developing on light-exposed skin and (2) the observance of dermal colloid under light microscopy.

Lesions are usually asymptomatic aside from occasional pruritus and are only distressing to patients due to their unsightly appearance. Pigmented colloid milium has a distinct clinical presentation. Colloid milium can involve upper eyelids in isolation, sparing the lower eyelids and facial skin. Such rare presentations should be kept in mind while examining similar lesions. Some entities to consider in the differential include systemic amyloidosis, primary cutaneous amyloidosis, syringomas, sarcoidosis, steatocystoma multiplex, lipoid proteinosis, molluscum contagiosum, papular mucinosis, and sebaceous hyperplasia. Dermabrasion, cryotherapy, and diathermy have been tried with limited success.

Milium -Prevention and Treatment Tips

1. Cryotherapy and chemical peels also treat Colliod millium.

2. Sunscreen use may also be helpful.

3. Genetic counseling is advisable for the rare juvenile form.

4. Solar elastosis is marked and closely approximated to the colloid.

Basal Cel Epithelioma - Treatment and Prevention Tips


A basal cell carcinoma is a skin cancer that originates from basal keratinocytes in the top layer of the skin. These tumors typically appear on sun-exposed skin, are slow growing, and rarely metastasize. In the United States skin cancer is the most common malignant tumor. Basal Cell Cancer will affect one in five Americans. It is most often found on the face, neck, hands, or other parts of the body that have been exposed to the sun. Basal cell carcinoma is usually a problem for people with fair skin and a poor ability to tan. In the United States, Caucasians have a 28% to 33% chance of developing a basal cell carcinoma over a lifetime. These cancers seem to be associated with exposure to ultraviolet light; they tend to develop on sun-exposed areas.

Basal cell carcinomas are most common from middle age until old age. Basal cell carcinomas are caused by genetic damage to a skin cell. Basal cell carcinoma is usually a problem for people with fair skin and a poor ability to tan. Exposure to sunlight, the most frequent association (UVB, 290-320 nm, which causes sunburn. Other determining factors include your family's history of skin cancer problems and an impaired immune system. Basal cell carcinoma is less serious than the other two types of skin cancer. Interferon alpha injected into the tumor is sometimes effective for basal cell carcinomas. Other imiquimod cream has been used recently for the treatment of BCC. Electrodesiccation and curettage is a short procedure and is effective in treating primary nodular.

Liquid nitrogen is applied to the clinically apparent tumor.Cryosurgery has good cosmetic results and good cure rates when treating tumors with well-defined clinical margins (eg, nodular BCC). Ionizing radiation is a good treatment option for patients who are not surgical candidates, especially those patients who have facial tumors. Mohs micrographic surgery is time consuming, and patients might require additional anesthesia before each stage. Radiation therapy requires multiple visits. Genetic disorders such as nevoid basal cell carcinoma syndrome, xeroderma pigmentosum, and albinism. Avoid sun exposure, wear hats and other protective clothing, and use sunscreens with a sun protection factor of at least 15.

Basal Cell Epithelioma -Prevention and Treatment Tips



1. Radiation therapy is less effective for nonfacial tumors.

2. Avoid sun exposure, wear hats and other protective clothing.

3. Interferon alpha injected into the tumor is sometimes effective for basal cell carcinomas.

4. Imiquimod cream has been used recently for the treatment of BCC.

Cryptococcosis - Treatment and Prevention


Cryptococcosis is an infection caused by inhaling the fungus Cryptococcus neoformans. The infection commonly starts following inhalation of the organism. Most cases occur in people whose resistance to infection is lowered. Cryptococcus is one of the most common life-threatening fungal infections in AIDS patients. Cryptococcosis is an opportunistic infection that puts people with immune system diseases at higher risk of developing more serious forms of the disease. In the United States, 6-10% of all patients with aids get cryptococcosis. Cryptococcus gattii causes infections in immunocompetent people. Cryptococcal disease is reportedly more common in men than in women. C neoformans can cause an asymptomatic pulmonary infection followed later by the development of meningitis.

People who have defects in their cell-mediated immunity, for example, people with AIDS, are especially susceptible to disseminated cryptococcosis. People with a functioning immune system who have Cryptococcus in only a small part of their lungs usually do not require any treatment. Drugs used to treat people with a weakened immune system include fluconazole. Flucytosine is unreliable if used alone, and resistance develops rapidly; in cryptococcal disease, administer this drug in conjunction with amphotericin B. Do not use currently available azoles (ketoconazole and itraconazole) in the initial treatment of disseminated or CNS cryptococcal disease. Minimize doses of corticosteroid medications.

Safer practices reduce the risk of acquiring HIV. AIDS patients often have a reduced response to Amphotericin B and flucytosine, therefore after initial treatment as above, oral fluconazole can be used. Amphotericin B desoxycholate is the DOC for initial therapy of cryptococcal infection. This drug has a faster onset of action than fluconazole. A new oral solution of itraconazole is available and has improved bioavailability compared with the capsules. Amphotericin B desoxycholate is the DOC for initial therapy of cryptococcal infection. This drug has a faster onset of action than fluconazole. Lipid preparations of amphotericin B are very expensive and, although less nephrotoxic, are not more effective.

Cryptococcosis - Prevention and Treatment Tips

1. Minimize doses of corticosteroid medications.

2. Safer practices reduce the risk of acquiring HIV .

3. Amphotericin B desoxycholate is the DOC for initial therapy of cryptococcal infection.

4. Lipid preparations of amphotericin B are very expensive.

5. Do not use currently available azoles in the initial treatment of disseminated.

6. Fluconazole is a bis-triazole that differs from other azoles by the substitution of a triazole group for the imidazole group.

Malignant Melanoma - Treatment and Prevention


Malignant melanoma is a cancer which usually starts in the skin. It is one of the rarer types of skin cancer but causes the majority of skin cancer related deaths. It causes the greatest number of skin cancer-related deaths worldwide. Early detection of thin cutaneous melanoma is the best means of reducing mortality. Melanomas are divided into 4 main types. Superficial spreading melanoma is the most common type of melanoma. About 7 out of 10 (70%) are this type. Melanoma can also start in the mucous membranes of the mouth, in the eye or other places in the body where melanocytes are found. Nodular melanoma occurs most often on the chest or back. It is most commonly found in middle-aged people.

Lentigo maligna melanoma is most commonly found on the face, particularly in older people. It grows slowly and may take several years to develop. The primary symptom of any skin cancer is usually a mole, sore, lump, or growth on the skin. Melanomas are most common on areas exposed to the sun. Certain types of melanoma have worse prognoses but this is explained by their thickness. Local recurrences tend to behave similarly to a primary unless they are at the site of a wide local excision since these recurrences tend to indicate lymphatic invasion. Various chemotherapy agents are used. Radiation therapy is often used after surgical resection for patients with locally

Surgery - remove the melanoma and a ring of tissue around it. Chemotherapy - to kill cancer cells that have spread throughout the body.Radiation therapy - to kill cancer cells that may have spread beyond the tumor. Applying a sunscreen with SPF 15 or higher, every day. Wearing protective clothing, including hats and sunglasses. DTIC therapy is associated with a response rate of 15 to 25%, with only 5% of patients achieving a complete response. Only interferon alpha-2b has been shown to be effective in the adjuvant setting. Radioimmunotherapy of metastatic melanoma is currently under investigation. Randomized prospective studies show that 2-cm margins are appropriate for tumors of intermediate thickness.

Malignant Melanoma - Prevention and Treatment Tips

1. Applying a sunscreen with SPF 15 or higher, every day.

2. Wearing protective clothing, including hats and sunglasses.

3. Surgery remove the melanoma and a ring of tissue around it.

4. Chemotherapy to kill cancer cells that have spread throughout the body.

5. Radiation therapy - to kill cancer cells that may have spread beyond the tumor.

6. Laser treatment may be used to treat melanoma which has come back in the skin.

7. Avoid prolonged exposure to the sun and be aware of the intensity of the sun.

8. Ultraviolet radiation from sunbeds has a similarly damaging effect to intense sunlight.

Malignant Melanoma


Drug eruptions can mimic a wide range of dermatoses. Lichenoid eruptions are rather common dermatoses that can be induced by a great number of environmental agents and are clinically but not pathogenetically well defined. Our hypothesis was confirmed by clinical resolution three weeks after discontinuation of sildenafil citratus; moreover, the patient avoided the drug for about four months, and the eruption didn't reappear. A drug-induced reaction should be considered in any patient who is taking medications and who suddenly develops a symmetric cutaneous eruption. Lichenoid eruptions are quite common in children and can result from many different origins. In most instances the precise mechanism of disease is not known, although it is usually believed to be immunologic in nature.

Many of these lesions are self-limited and only require symptomatic treatment, although corticosteroids can hasten resolution in certain disorders. Discontinuation of the medication is often sufficient for resolution of lichenoid drug eruptions. Drug eruptions may be divided into immunologically and nonimmunologically mediated reactions. Immunologically mediated reactions and nonimmunologically mediated reactions. Nonimmunologically mediated reactions may be classified according to the following features: accumulation, adverse effects, direct release of mast cell mediators. Idiosyncratic reactions are unpredictable and not explained by the pharmacologic properties of the drug.

LDE is a rare skin reaction that can be associated with several drugs. Drug eruptions occur in approximately 2-5% of inpatients and in greater than 1% of outpatients. Topical steroids such as clobetasol proprionate and betamethasone proprionate ointments are generally applied for 4 -6 week courses. Drug reactions are a common reason for litigation. Mild topical steroids (eg, hydrocortisone, desonide) and moisturizing lotions are also used, especially during the late desquamative phase. Therapy for exanthematous drug eruptions is supportive in nature. First-generation antihistamines are used 24 h/d. Other treatments include long term antibiotics, oral antifungal agents, phototherapy, acitretin, methotrexate and hydroxychloroquine.

Drug Eruptions Lichenoid - Prevention and Treatment Tips

1. Topical steroids such as clobetasol proprionate and betamethasone proprionate ointments also use.

2. Hydrocortisone foam can be use.

3. Steroid injections into affected areas may be useful for localised disease.

4. Systemic steroids may have serious side effects, so discuss this treatment with your dermatologist.

5. Other treatments include long term antibiotics, oral antifungal agents, phototherapy, acitretin, methotrexate and hydroxychloroquine.
