Azithromycin or clarithromycin generic glucophage 500 mg mastercard, plus ethambutol are effective and well-tolerated regimen for treatment of disseminated disease generic glucophage 850 mg on line. Because of increasing reports of dapsone resistance buy generic glucophage 850mg line, treatment of leprosy with combinations of the drugs is recommended buy 850mg glucophage free shipping. Therefore, the combination of dapsone, rifampin, and clofazimine is recommended for initial therapy. Sulfones are well absorbed from the gut and widely distributed throughout body fluids and tissues. Because of the probable risk of emergence of rifampin-resistant M leprae, the drug is given in combination with dapsone or another antileprosy drug. Clofazimine The absorption of clofazimine from the gut is variable, and a major portion of the drug is excreted in feces. Clofazimine is given for sulfone-resistant leprosy or when patients are intolerant to sulfone. The most prominent untoward effect is skin discoloration ranging from red-brown to nearly black. The antifungal drugs fall into two groups: antifungal antibiotics and synthetic antifungals. Antifungal antibiotics Amphotericin B Amphotericin B is poorly absorbed from the gastrointestinal tract. Oral amphotericin B is thus effective only on fungi within the lumen of the tract. The pore allows the leakage of intracellular ions and macromolecules, eventually leading to cell death. Adverse Effects: The toxicity of amphotericin B which may occur immediately or delayed include fever, chills, muscle spasms, vomiting, headache, hypotension (related to infusion), renal damage associated with decreased renal perfusion (a reversible) and renal tubular injury (irreversible). It has activity against yeasts including; Candida albicans and Cryptococcus neoformans; molds, Aspergillus fumigatus. Clinical Use: Amphotericin B remains the drug of choice for nearly all life-threatening mycotic infections. Used as the initial induction regimen for serious fungal infections (immunosuppressed patients, severe fungal pneumonia, and cryptococcal meningitis with altered mental status). Nystatin Nystatin has similar structure with amphotericin B and has the same pore-forming mechanism of action. Nystatin is active against most Candida species and is most commonly used for suppression of local candidal infections. Nystatin is used in the treatment of oropharyngeal thrush, vaginal candidiasis, and intertriginous candidal infections. Griseofulvin Griseofulvin is a fungistatic and used is in the treatment of dermatophytosis. Griseofulvin is deposited in newly forming skin where it binds to keratin, protecting the skin from new infection. It must be administered for 2-6 weeks for skin and hair infections to allow the replacement of infected keratin by the resistant structures. Nail infections may require therapy for months to allow regrowth of the new protected nail and is often followed by relapse. Adverse effects include an allergic syndrome much like serum sickness, hepatitis, and drug interactions with warfarin and phenobarbital. Griseofulvin has been largely replaced by newer antifungal medications such as itraconazole and terbinafine. Clinical Use: Active against Cryptococcus neoformans, some Candida species, and the dematiaceous molds that cause chromoblastomycosis. Clinical use at present is confined to combination therapy, either with amphotericin B for cryptococcal meningitis or with itraconazole for chromoblastomycosis. Adverse Effects: The adverse effects of flucytosine result from metabolism (intestinal flora) to the toxic antineoplastic compound flucytosine. Bone marrow toxicity with anemia, leukopenia, and thrombocytopenia are the most common adverse effects, with derangement of liver enzymes occurring less frequently.

The doctors sometimes prescribe an antibiotic or some other medicine to the relatives of such a patient in order to avoid the disease; such medicines should be. Due to the dwindling of these cells, which are the most important defence mechanism of the body, the entire immune system of the body gets affected and the immunity power of the body gradually decreases. Disposable syringes and needles should be used for injections and injections should be avoided for common diseases unless absolutely essential. The patient gets fever, muscular pain, swelling of lymph glands, red spots on the skin, swelling in the throat etc. After this phase various symptoms are seen like swelling of the lymph glands, continuous or frequent fever, ulceration in the mouth and throat, splenomegaly, prolonged coughing, weight loss etc. This test is a screening test and if it is positive, confirmation is done with the help of Western Blot test. Damage to the nerves of the nervous system result in neuritis caused by infectious organisms like Herpes etc. As a result the quality of the patients life can be improved, the infectious diseases can be prevented and the patient can move around and can remain mentally sound. Many a times the doctors use a combination of three medicines whose average monthly expense is around Rs. The irony is that in spite of this expenditure, the disease is neither completely cured nor controlled. Therefore, if the diagnosis of these organisms is done in an early stage and treated immediately these infections can be cured. They cause various common and specific symptoms depending on their size, type, location, properties and histology. Improvement in the surgical techniques and anesthesia, developments in stereo tactic and the micro neurological techniques, remarkable advances in radiation as well as chemotherapy have brightened the future of patients of brain tumors. Out of these many, are cases of cancer -that originate in the brain (primary) like glioma or spread from other parts of the body to the brain. Increased Intracranial pressure: Increase in the size of the tumor increases the pressure inside the skull (a fixed vault) as well as on the brain, causing symptoms like headache on both sides, nausea-vomiting, blackouts, uneasiness and diplopia. All cases of headache do not indicate brain tumor, only in 1 % of the cases, the cause of headache is brain tumor. But if a healthy individual starts experiencing headaches of increasing intensity, it is essential to get examined by a specialist. Therefore there can be a gradual increase of paralysis, speech loss, memory loss or lack of body co-ordination. In some patients there is only a behavioural or a personality change, or loss of bowel or bladder control : 3. Seizures or unconsciousness can also be an important symptom especially if it is accompanied by headache or paralysis; if so immediate investigations are necessary. Usually, only if there is more than one of the above symptoms, the possibility -of a brain tumor in the patient is high. In this condition as well as in small children a sedative or low dose of anesthesia is given and the investigation is carried out. This investigation is very useful in the diagnosis of the infectious diseases of the brain like meningitis, encephalitis etc. Some cancerous tumors grow very rapidly and are serious, in which the patient’s lite span is only six months to 3 years e. If these are diagnosed in early stages and operated upon by a capable surgeon the life of the patient can be saved. Not only this, the patient can lead a near normal life, apart from some minor problems and weakness At the most he may have to take drugs for prevention of seizures for the rest of his life. Sometimes it so happens, that the symptoms of brain tumor may point out the presence of cancer in some other part of the body, but it is too late by then. Treatment : The role of a neurosurgeon is more important in the treatment of a brain tumor than a neurologist. There is so much advancement in the treatment of brain tumors that some types of tumors can be stopped from growing, and eventually shrunk by the use of gamma radiation, without opening the brain.
