After surgery for breast cancer best buy nicotinell quit smoking idaho, a patient is to undergo chemotherapy with a regimen that consists of cyclophosphamide purchase nicotinell us quit smoking idaho, methotrexate purchase 500 mg cyklokapron, 5-fluorouracil, and doxorubicin. Which one of the following agents is most likely to be protective against the toxicity of methotrexate? Which anticancer drug, acting mainly in the G2 phase of the cell cycle, can cause blisters on the palms of the hands and soles of the feet and can make it difficult for the patient to breathe? Resistance to which anticancer drug, used mainly in childhood leukemia, is high in neo- plastic cells that have low activities of hypoxanthine guanine phosphoribosyltransferase? Bladder irritation with hematuria is a fairly common complaint of patients treated with cyclo- phosphamide. It appears to be due to acrolein, a product formed when cyclophosphamide is bioactivated by liver P450 to form cytotoxic metabolites. Urinary tract problems may also occur with methotrexate from crystalluria due to its low water solubility. All of the drugs listed are antimetabolites used in cancer chemotherapy or as immunosuppressants. Mercaptoethanesulfonate (rnesna), which inactivates acrolein, is available for protection against hemorrhagic cystitis in patients treated with cyclophosphamide and related drugs. It helps to know which anticancer drugs are cell-cycle specific and which have characteristic toxicities. Bleomycin fits both categories; acting mainly in Gz, it is cell-cycle specific and is distinctive for causing mucocutaneous reactions and pulmonary dysfunc- tion. Busulfan and procarbazine may also cause pulmonary toxicity, but neither drug is cell-cycle specific. Anti-D immunoglobin is given to Rh-negative mothers shortly after parturition to prevent hemolytic disease in future births. Which one of the following agents is paired correctly with its suggested clinical use and/or mechanism of action? Esmolol Theophylline, beta agonists I Ethanol, fomepizole Methanol or ethylene glycol Flumazenil Benzodiazepines, zolpidem, zaleplon Naloxone Opioid analgesics Oxygen Carbon monoxide Penicillamine Copper (e. Evidence supporting the clinical effectiveness of herbal products is commonly incomplete. Symptoms of iron poisoning in a 3-year-old child may include severe gastrointestinal distress with hematemesis, a shock-like state with marked dehydration and progressive hemorrhagic gastritis. Regarding the management of iron toxicity, which one of the fol- lowing statements is accurate? Which one of the following symptoms is most likely to be associated with lead poisoning? Gastric lavage should be attempted with care regarding aspiration, but changes in urine pH have no effect on the elimination of iron.
For feebleness of the mucous membranes 35 mg nicotinell visa quit smoking results timeline, with a tendency to breaking down of the tissues order nicotinell 17.5 mg fast delivery quit smoking government programs, given internally and as far as possible applied locally discount micronase 2.5 mg without a prescription, it gives good results. In painful diarrhea and dysentery with passages of blood and mucus, also in bad cases of typhoid, Dr. The doctor in these cases used it in decoction, and so prepared it can be given freely. In bad bruises, in tibial ulcers, and also in syphilitic sores, it makes a good local application. He adds from ten to thirty drops of the, fluid medicine to a two-ounce prescription, consisting of glycerin, one dram, aqua dest. The specific indications for its use in catarrh are, “a full, stuffy sensation in the head and throat. The compound syrup of the hypophosphites makes a splendid vehicle in which to administer it. Administration—This agent seems to exercise but little influence in Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 34 physiological doses. A few drops of the specific anthemis or the German tincture in a glass of water in teaspoonful doses every few minutes or every hour will accomplish good results when directly indicated. Specific Symptomatology—Severe pain in infants, from simple causes, extreme susceptibility to pain, general hyperaesthesia, subjective, acute, transient, sharp pains. The following indications were given in The Medical Century, and can be relied upon: There is perpetual hyperesthesia; there is starting and, jumping. The child is cross, wants to be carried; stool apt to be soft and charged with sulphuretted hydrogen; if there be diarrhea accompanying, the passages will look like the white of an egg mixed with greens. Tooker says, “the remedy of all remedies and the one most often called for during the teething period is chamomile. This remedy is to children what pulsatilla is to women, a veritable vade mecum, “ Chamomile, acts mildly on the nervous system to subdue irritability and on the gastro-intestinal tract to relieve irritation there. It is adapted to the restless, peevish, irritable, discontented, and impatient infant who insists on being carried in arms constantly. With these there is usually hepatic tenderness with watery or greenish, slimy discharges, yellowish and white lumps of undigested curds, the fecal excordiating the external parts. There is often difficulty and pain in urination, and bloating of the abdomen with flatulence. It prevents convulsions by relieving the irritation, but has not sufficient antispasmodic effect to control the convulsions. The many conditions with the adult woman it is beneficial, especially to those in the latter months of pregnancy where there are present false pains, nervous twitching, reflex cough, explosion of irascibility; where there is fretfulless, peevishness, impatience and discontent; where there is morbid sensitiveness to pain; where there are sudden fits of temper during menstruation with muscular twitchings. Therapy—This agent in hot infusion is emetic, a stimulating diaphoretic, and it promotes the menstrual flow when suppressed from cold.
Those conditions which occur from getting up too soon after confinement are improved by it buy generic nicotinell 17.5mg online quit smoking 7 weeks ago, and those where the parts are slow in recovering tone purchase discount nicotinell on line quit smoking 800 quit now, from any cause cyklokapron 500 mg otc, or where there is danger of permanent prolapse from engorgement, are benefited by it. Specific Symptomatology—Neuralgic pain in the uterus, ovaries, and mammae, acid leucorrhea excoriating to the labia, causing an eruption about the vulva and inflammation of the vagina; nausea from uterine disease or pregnancy; headache from uterine disease; nervous sick- headache; chronic inflammation of the uterus, with displacement; tedious recovery after child-birth; amenorrhea, with burning pain in the ovaries; distress about the heart, with prolapse of the uterus; pain under the left breast; dysmenorrhea; neuralgic pain in the uterus and ovaries Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 273 extending down the inside of the thighs; a sense of weight and downward pressure in the lower abdomen; uterine displacements in general from debility. Therapy—These symptoms of uterine disease, cured or relieved by tiger lily, show the action of the remedy within a limited sphere; but it is probable that it has a much wider range of action, as we find that the common white meadow lily was employed by the early settlers in this country as a general and local tonic in prolapsus uteri; and as a tonic in debilitated states of the female organs of generation, and in dropsy, while the root of the white pond lily was used as a local application to ulcers and inflammations. John King says: “I recollect a lady who, several years since, was pronounced by several physicians to have uterine cancer, and which resisted all their treatment; she was permanently cured by a squaw, who gave her to drink freely of the decoction of a root, as well as to inject it in the vagina, which proved to be that of the white pond lily—Nuphar Alba. Baldwin, of Michigan, uses the fluid extract of Nuphar Lutea in the local treatment of chronic uterine disease of whatever character or however severe, with the most gratifying results. Specific Symptomatology—Persistent, dry, hard, ringing or resonant Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 274 bronchial cough, hoarse, barking or metallic cough. It is peculiarly sedative to the entire mucous surfaces of the post-nasal region and bronchial tubes. The experience of the writer has proven it specific in the peculiar, deep, resonant, barking, winter cough, without secretion, common to many ladies in the northern States, usually absent in the summer, very persistent, stubborn and difficult to cure. In every case the cough failed to recur in the following winter, as it had recurred before in several preceding winters. Note—In the early editions of my work on Materia Medica, this agent was classed from our knowledge of its action per os, as a nauseating expectorant and respiratory sedative. Since that time, the very wide observations made of its action hypodermically have changed the most of our ideas concerning it, and have placed it in an entirely different class. Given hypodermically but very few patients are nauseated by it, and almost the whole number, notwithstanding its sedative and anti-spasmodic influence, experience a physical uplift from its action. I have thought best, however, to leave this agent in its original class, until laboratory experiments have proven its exact influence upon the nervous and circulatory systems. Tinctura Lobeliae, Tincture of Lobelia; dose, from five to thirty Specific Medicine Lobelia; dose, from one to twenty minims. Subculoid (hypodermic) Lobelia; dose, from two to sixty minims; usually from ten or thirty minims repeated as occasion demands. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 275 The preparation of lobelia which is to be used hypodermically, must be selected with great care. If the agent be given internally, any good fluid preparation is effective, but in its hypodermic use, local irritation, nausea, severe vomiting, even general prostration occur more frequently from the ordinary fluid preparations. If depression with the above complications can be properly antagonized, and is not objectional in a sthenic patient. Extended and persistent experimentation has been made nearly as possible a perfect fluid preparation for hypodermic use. This is devoid to a very large extent of the objectionable features of the other preparations, and so nearly devoid of emetic properties that this is now considered a negligible quality. It is always best however to use any preparation hypodermically warmed, the parts aseptic, and to apply a hot compress over the seat of the application immediately for a few minutes. Except for its local effects, there is but little difference between the Subculoid lobelia and the specific medicine lobelia.
