Abbreviations And Descriptions Of Diseases -- Lesson 258

In this post we would learn about some abbreviations and descriptions of diseases. The abbreviation of bx is Biopsy, Derm. is Dermatology, PPD is Purified proteinderivative, PUVA is Psoralen-ultraviolet A light therapy, SLE is Systematic lupus erythematosus, DLE is Discoid lupus erythematosus, subq is subcutaneous.

The descriptions of some of the diseases are:
1. Candidiasis: [Candidiasis means yeast-like fungus]: This fungus is generally present on mucous membranes, skin, and vaginal mucosa. Under such conditions (more warmth; administration of birth control pills, antibiotics and corticosteroids; debilitated states; infancy), and it can turn to a pathogen and cause localized or generalized mucocutaneous disease. The examples of such are paronychial lesions, lesions in areas of the body where (groin, perianal, axillary, inframammary, and interdigital), rubbing opposed surfaces is common, thrush (white plaques attached to oral or vaginal mucous membranes), and vulvovaginitis.

2. Cellulitis: With severe inflammation of the dermal and subcutaneous layers of the skin, this is a common nonsupporative infection of connective tissue. Cellulitis appears on an extremity as a reddish-brown area of edematous skin. The cause of entry for bacteria in most cases are caused by streptococci of which a surgical wound, skin ulcer, puncture, or patch of dermatitis occur. Therapy entails rest, elevation, hot wet packs, and penicillin. Because of the infection may extend directly to the brain, any cellulitis on the face should be given in special attention.

3. Mycosis fungoides: By the infiltration of malignant lymphocytes, this is a rare chronic skin condition. The generalized erythroderma and large, reddish raised tumors that spread and ulcerate are all characterized. In few cases, the malignant cells may involve lymph nodes and other organs. Treatment with tropical nitrogen , mustard and radiation can be effective in controlling the disease.

Physical Examination of the Skin:
There are a variety of lesions which were seen on the face, shoulders, and back. The predominant lesions are pustules on an inflammatory base. Over the chin and forehead, so many pustules are confluent or running together. On the face, Comedones are present especially along the nasolabial folds. On the lower cheeks, and chin inflammatory papules are present. Large abscesses and ulcerated cysts are present over the upper shoulder area. So many number of scars are present over the face and upper back.

In the next post we would come through combining forms, suffixes and their meaning.

Laboratory Tests And Clinical Procedures -- Lesson 257

In this post we would learn some Laboratory tests and some clinical procedures
Laboratory tests:
1. Bacterial analyses: Samples of purulent or pus-filled material or exudate which means fluid that accumulates in a space or passes out of tissues which are sent to the laboratory to determine which type of bacteria are present.

2. Fungal tests: On a growth medium, scraping from skin lesions for several weeks and then examined microscopically for evidence of fungal growth.

Clinical Procedures: 

1. Mobs Surgery: Thin layers of a malignant growth are removed, and eachi is tested under the microscope, which is also called microscopically controlled surgery.

2. Cryosurgery: The application of intensely cold liquid nitrogen destroyed the tissue.
               
3. Skin biopsy: Pigmented nevi, chronic dermatoses, or any lesion in which there is the possibility of present or future malignant change, are removed and sent to the pathology labortory for examination. A biopsy which is also called Punch biopsy is used to obtain tissue in cases in which complete excision is not feasible involves use of a surgical instrument that removes a core of tissue by rotation of its sharp circular edge. In a shave biopsy, tissue is excised using a cut parallel to the surface of the surrounding skin.

4. Skin testing for allergy or disease: By applying to the skin a small piece of gauze or filter paper on which has been placed a suspected allergy-causing substance is performed in the patch test. If the area becomes reddened or swollen, the result is considered positive. The scratch test involves making several scratches in the skin and inserting a very minute amount of test material in the scratches. The test is considered negative if no reaction occurs. Intradermal tests are performed by injection of a reactive substance between layers of the skin and observation of the skin for a subsequent reaction. This test is used for the detection of sensitivity to infectios agents such as tuberculosis also called Mantoux tests, PPD test or diptheria also called Schick test. Strong reactions indicate ongoing infection.

In the next post we would come across some abbreviations and applications.

Cancerous Lesions -- Lesson 256

In this post we will learn about Cancerous Lesions:
1. Basal cell carcinoma: - The basal cell layer of the epidermis consists malignant tumor. This is the most frequent type of skin cancer. It is a slow-growing tumor that usually occurs on the upper half of the face, near the nose. This almost never metastasizes.

2. Kaposi’s sarcoma: - Usually on the lower extremities, malignant, vascular, neoplastic growth characterized by cutaneous nodules. Nodules range in color from deep pink to dark blue and also to purple. The acquired immunodeficiency syndrome also known as AIDS is the condition which is also associated.

3. Malignant melanoma: - The melanocytes which are contained in cancerous growth. This malignancy is attributed to the intense exposure to sunlight that many people experience. With not regular borders, melanoma usually begins as a mottled, light brown to black, flat macule. The lesions which may turn shades of red, blue, and white and may crust on the surface and bleed. In the preexisting moles or dysplastic nevi melanomas often arise and frequently appear on the lower legs, neck, upper back, and head.

Biopsy is required to diagnose melanoma, and prognosis following excision is determined through the skin layers. On this basis melanomas have been classified levels. The growth is confined to the epidermis and subcutaneous layer. Melanomas often metastasize to the lung, liver, and brain. For this treatment includes excision of the tumor, regional lymphdenectomy, radiotherapy or chemotherapy/immunotherapy to prevent metastasis.

4. Squamous cell carcinoma: - The squamous epithelial cells of the epidermis consists malignant tumor. This tumor may grow other than the skin, wherever squamous epithelium is found (mouth, larynx, bladder, esophagus and so forth). It may arise from actinic or sun-related, keratoses and metastasize to lymph nodes. The treatment for this is surgical excision or radiotherapy.

In the next post we shall come through laboratory tests, clinical procedures and abbreviations.
