Joint pains are referred to as Arthralgia - ranging from mild to severe. The pain can be felt as either dull and throbbing or severe and sharp. There is pain and tenderness in the affected joint. Stiffness and reduced mobility is experienced. Typically Arthralgia is caused due to arthritis, joint injury, infection or other medical conditions. Typically minor cases of Arthralgia are treated at home with ice packs, warm baths or stretching. Severe cases of Arthralgia may need steroids, joint aspiration or physiotherapy.
Skin Cancer Pill
The choice of treatment for basal cell carcinoma includes surgical removal of the affected area by excision, cryosurgery or radiation therapy. The contemporary method of treatment introduced is through the administration of skin cancer pills called as Erivedge approved by United States food and drug administration society. Erivedge pills are designed to treat advanced levels of basal cell carcinoma. This drug was designed to prevent surgical or radiation associated intervention in sensitive areas such as the nose regions of the face where the carcinoma predominantly occurs.
Erivedge the revolutionary pill for the treatment of advanced basal carcinoma is chemically known as vismodegib. This oral medicine is associated with the prevention of overactive signaling of the Hedgehog pathway by binding to a trans membrane protein occurring in basal cell carcinoma. The continuum of the Hedgehog pathway may result in the metastases of the carcinoma.
Vismodegib (erivedge) is highly permeable and has low aqueous solubility. The plasma protein binding in patients is very high. It binds to albumin and alpha- 1acid glycoprotein. The metabolic pathways associated are oxidation, glucouronidation and also pyridine ring cleavage. The excretion of the drug predominantly happens through the hepatic route. The absorption and retention of the drug occurs in feces and urine.
Dosage and administration
The recommended dosage of erivedge is 150mg taken orally once a day. The duration of medication has to continue until the complete prophylaxis of the disease. Discontinuation of erivedge is only advisable under the incidence of drug toxicity. Additional doses of erivedge are not recommended in case of missing a dose; the next dose has to be resumed. Erivedge intake does not depend upon food intake.
Contraindications and adverse effects
Erivedge is considered as teratogenic, embryo toxic and fetotoxic drug and hence it is not recommended for pregnant women. If administered, the effects include severe birth defects such as craniofacial anomalies, absent or fused digits and also open perineum. Erivedge is also not advisable for nursing mothers as it may be excreted in the milk.
Erivedge consuming patients are advised not to donate blood for a period of seven months. Many adverse effects were reported in the clinical trials conducted on erivedge some of which are muscle spasms, arthralgia, fatigue, diarrhea, weight loss, alopecia, constipation and also decreased appetite. Erivedge intervenes with other drugs such as clarithromycin etc. in leading to adverse reactions. Erivedge usage is not recommended in children as it intervenes in the epiphyseal growth plate affecting the bones; causing damage to the teeth by necrosis, cysts in the dental pulp and also ossification of the root canal.
Geriatric use of erivedge is also not recommended. The other conditions under which the use of erivedge is not recommended is in patients having hepatic and renal impairments.
Sjogren syndrome is an autoimmune disorder causing conditions such as xerostomia and Xerophthalmia. It was first discovered by Henrick Sjogren. The symptoms associated with this disorder are often chronic and occur due to damage or impairment of the exocrine glands caused due to the lymphocytic infiltrates and hypersensitivity reactions. The onset of Sjogren syndrome predominantly occurs in the region of salivary glands and lacrimal glands. The primary form of Sjogren syndrome is generally associated with external glandular symptoms such as dry eyes and dry mouth without any connective tissue damage. The secondary form of the Sjogren syndrome usually occurs because of preexisting autoimmune disorders.
Clinical manifestations of Sjogren syndrome
Sjogren syndrome usually occurs in the older age group; however exceptions have been reported on it affecting younger persons. The factors causing Sjogren syndrome are predominantly genetical or environmental. Neuro-endocrine impairment plays a significant role in the onset of the Sjogren syndrome. HLA-DR genotype is the predominant factor in the genetic propagation of the disease.
Sjogren syndrome is associated with a cascade of symptoms related to many organ systems and their functions. The affected regions are ocular, oral, ontological, laryngeal, vascular, neurologic and endocrine systems respectively. The effect of the Sjogren syndrome is mainly on the head and neck region and hence the sense organs are affected to a larger extent. Other clinical conditions include loss of hearing, arthralgia, myalgia and also frequent epistaxis. Sjogren syndrome if not treated, can lead to serious conditions such as lymphoma and renal failure.
Diagnosis and treatment of Sjogren syndrome
Sjogren syndrome is diagnosed by using radiological, pathological and serological analysis. Schirmer's test is used in the diagnosis of Xerophthalmia. It is used to estimate the tear secretion level of patients suffering with dry eye conditions. The decreased levels or absence of tear secretion indicates probability of Sjogren syndrome. Salivary biopsy is advised for patients suffering xerostomia. The pathological analysis of the salivary glands also reveals underlying infiltration and damage caused to the exocrine glands. Serological analysis of the Sjogren syndrome are generally associated with low WBC counts, increased erythrocyte sedimentation rates, elevated levels of protein and hyper-gammaglobulinemia of IgM. Careful clinical study of the diagnostic parameters along with symptoms is necessary to rule out false positive results.
The treatment of Sjogren syndrome is generally a slow process because it is an autoimmune disorder. Immunosuppressive drugs and salivary substitutions are some of the methods administered to manage Sjogren syndrome. Pilocarpine an FDA approved tear stimulating drug is widely used for the treatment of dry eyes.
