Patients who present with overwhelming sepsis due to gastritis chronic cure cheap 20 mg nexium with mastercard pneumonia generally lack one or more of these defenses curing gastritis with diet buy nexium 40 mg otc. Such patients complain of a brief prodromal upper respiratory illness followed by fever gastritis diet 1200 generic nexium 20 mg fast delivery, a single shaking chill gastritis diet ???order 20 mg nexium with amex, pleuritic chest pain, and a cough productive of purulent or "rusty" sputum. Physical examination reveals signs of consolidation, which are readily confirmed by chest radiography. At the other extreme might be an elderly, confused patient who presents with only deterioration in mental function. The physician should explore the presence of risk factors, including chronic illnesses, recent acute illnesses, illness in family members, use of alcohol or other drugs, and possible exposures to infectious agents. A thorough physical examination, posteroanterior and lateral chest radiographs, and blood leukocyte count with differential cell count should be performed. On the basis of the data available from these steps, it is usually possible to conclude that pneumonia is present. Further, because most patients with pneumonia respond satisfactorily to simple, relatively nontoxic antibiotic regimens, the need to document the precise cause of the process is uncertain. The portion chosen should be purulent and contain fewer than 10 squamous cells and more than 25 leukocytes per low-power field. Often, such specimens contain a vast preponderance of a single species, and if these are encapsulated gram-positive cocci (pneumococci) or small pleomorphic gram-negative coccobacilli (Haemophilus), a presumptive diagnosis can be made. Problems arise when a predominant organism is less apparent, when enteric gram-negative bacilli are present, or when an adequate specimen cannot be obtained. Aerobic culture of expectorated sputum suffers from a lack of sensitivity (organisms causing pneumonia are not detected) and specificity (organisms are present that did not cause pneumonia); both sensitivity and specificity are only about 50%. The results may be improved by microscopic screening of the specimen prior to culture. Although some authorities have recommended that sputum cultures be abandoned except in unusual cases, others argue that the increasing incidence of antimicrobial resistance among agents causing community-acquired pneumonias mandates continued surveillance through routine cultures. Contamination of expectorated sputum during passage through the mouth can be avoided by collecting the specimen distal to the larynx. Needle aspiration through the trachea (transtracheal aspiration) or of the lung through the chest wall (thransthoracic lung aspiration) have been largely replaced by fiberoptic bronchoscopy, which has far fewer complications. Both the protected specimen brush and bronchoalveolar lavage techniques can be used; the former provides a small (0. A further advantage of bronchoscopy is that transbronchial lung biopsies can be obtained at the same time if a tissue diagnosis is needed. Invasive sampling approaches are certainly not needed in most patients with pneumonia but are indicated when a delay in accurate diagnosis may have serious consequences, such as in immunocompromised patients or patients whose conditions have worsened on empirical antimicrobial therapy. However, compared with conventional cultures, these techniques are expensive and relatively insensitive; they should be considered only when specific organisms are strongly suspected on clinical grounds. Uncontaminated specimens obtained via bronchoscopy or transtracheal or transthoracic aspiration provide better materials for immunodiagnosis than expectorated sputum. Cultures of the blood or pleural fluid, if positive, are highly specific, but only about 30% of patients with bacterial pneumonia have bacteremia. About the same percentage of pleural fluid aspirates are positive in the absence of antibiotic therapy, but only 10 to 15% of patients with pneumonia have pleural effusion. Blood cultures should be obtained in patients with serious illness due to pneumonia, and diagnostic thoracentesis should be performed if an effusion is large enough to be aspirated safely. In most patients, the history, physical examination, radiographic studies, and evaluation of the sputum by Gram stain provide all the required data. Additional procedures should be reserved for those patients in whom a delay in making an accurate diagnosis will have serious consequences or those in whom therapy cannot be reasonably planned on the basis of simpler approaches. Although a specific microbiologic diagnosis is seldom, if ever, possible on the basis of radiographic data alone, important clues to the cause of pneumonia and its distribution and severity may be gained by this technique (Table 82-4). Lobar or segmental consolidation suggests a bacterial cause for pneumonia, especially Streptococcus pneumoniae or Klebsiella pneumoniae. Consolidation may obscure the borders between the lung and adjacent structures. This obliteration is termed the silhouette sign and is very useful to localize infiltrates. Less well-defined and inhomogeneous radiographic densities, often described as "patchy" or "streaky" infiltrates, may be observed in bronchopneumonia caused by a variety of organisms, including bacteria and viruses. Cavitary infiltrates generally suggest the presence of a necrotizing infection from organisms such as Staphylococcus aureus, gram-negative bacteria, anaerobes, and M.

McCune-Albright syndrome (question 19) is characterized by endocrine dysfunction (peripheral precocious precocity, hyperthyroidism), irregularly bordered hyperpigmented macules ("coast of Maine" spots), and fibrous dysplasia of the bones that may lead to fractures. Kallmann syndrome (question 20), a form of hypogonadotropic hypogonadism, is associated with anosmia (absent sense of smell). Prader-Willi syndrome (question 21) is characterized by hypotonia, hypogonadism, and small hands and feet, with growth problems in the first year of life (secondary to feeding problems), followed by hyperphagia and obesity later in childhood. Turner syndrome is characterized by ovarian dysgenesis, short stature, webbing of the neck, and left-sided congenital heart disease, with an increased incidence of hypothyroidism. Laurence-Moon-Biedl syndrome is characterized by hypogonadism, retinitis pigmentosa, obesity, and polysyndactyly. Findings consistent with child abuse include specific types of fractures, such as metaphyseal ("corner" or "bucket handle") fractures. Other fractures highly suggestive of abuse include posterior and first rib fractures, fractures of the sternum, scapula, and vertebral spinous processes, and fractures in different stages of healing. Bruises on exposed areas, such as the knees, shins, elbows, and forehead, are common during childhood and are typical of accidental injury. Supracondylar fractures are common during childhood and usually occur when a child falls on an outstretched arm, and alone are not suggestive of abuse. Asthma is the most likely diagnosis because of the symptoms of recurrent cough and wheezing. This patient likely has mild persistent asthma, given the frequency and persistence of symptoms. Because asthma is an inflammatory disorder, antiinflammatory medications, such as cromolyn sodium or low-dose inhaled corticosteroids, are recommended for persistent asthma symptoms. In as many as 50% of patients with asthma, symptoms may develop during the first year of life. Smoking should not be allowed in any place that a child with asthma may visit, including the home and automobile. Although albuterol would be useful for the management of acute symptoms, it has no effective role in prevention, except for preventing symptoms of exercise-induced asthma. Foreign body aspiration is less likely in a child with both persistent and recurrent symptoms. In addition, inspiratory and expiratory films could not be obtained in an 11-month-old child; therefore, decubitus films would be indicated if foreign body aspiration was suspected. The most common cause of cardiac arrest in a child is a lack of oxygen supply to the heart. Respiratory problems that result in a lack of oxygen supply include choking, airway disease, lung disease, suffocation, and brain injury. The end result of any of these processes is decreased oxygen tension within the blood (hypoxia). Cardiac arrest can often be prevented if assisted breathing is administered rapidly. Seizures, poisonings, and trauma are also less common causes of cardiac arrest than hypoxia. Patients with celiac disease may present with vomiting, bloating, foul-smelling stools, or failure to thrive. This infant developed his symptoms after the introduction of wheat cereal that contains gluten. Gluten is found in wheat, rye, barley, and oats (if the oats are harvested in fields that also grow wheat). Celiac disease is a glutensensitive enteropathy in which antibodies to gluten cross-react and damage the mucosa of the small intestine, which results in flat, atrophic villi. Lactase deficiency causes bloating and watery stools, but not failure to gain weight. Gastroesophageal reflux disease may be associated with vomiting and irritability; however, stools are not foul-smelling. Patients with cyanotic congenital heart disease associated with reduced pulmonary blood flow, such as tetralogy of Fallot, do not respond with any increase of significance in the PaO2 level when given 100% oxygen.
A few agents cause an "asthma-like" reaction with cough gastritis gaps diet cheap 40mg nexium with visa, chest pain gastritis diet 900 cheap nexium 40 mg on-line, and wheezing atrophic gastritis symptoms webmd purchase 40mg nexium with visa. Toluene diisocyanate and other isocyanates (liberated as a gas in making polyurethane foams) gastritis zinc carnosine generic nexium 40 mg with visa, aluminum soldering flux, and platinum salts are typical examples. Reaginic and precipitating antibodies against platinum salts and soldering flux have been found in symptomatic individuals, suggesting an immunologic basis for the reaction. An allergic basis has not been demonstrated for the reaction to toluene diisocyanate. The symptoms usually subside after removal from exposure; however, chronic lung injury may occur if the exposure is prolonged. Such gases include chlorine (used in the chemical and plastics industries and to disinfect water), ammonia (used in refrigeration), sulfur dioxide (used in making paper and smelting sulfide-containing ores), ozone (generated in welding and in photochemical smog), nitrogen dioxide (released from decomposed corn silage), and phosgene (used in producing aniline dyes). Most of them cause injury by acting as a strong acid, a strong base, or an oxidant. Gases of chemicals that are strong acids or bases in water solution, such as hydrogen chloride, sulfuric acid, sulfur dioxide, and ammonia, tend to react more in the upper airways. The clinical response caused by irritant gases varies but appears to be closely related to the degree of acute irritation and to the water solubility of the gas. The less irritating gases, such as ozone and the oxides of nitrogen, phosgene, mercury, and nickel carbonyl, can be inhaled for prolonged periods and thereby cause injury throughout the respiratory system. Highly irritating and soluble gases, such as ammonia and hydrochloric acid, are less likely to be inhaled deeply and tend to result in immediate injury to the upper airways and have potential for obstruction secondary to mucosal edema. Less-soluble substances, such as chlorine, cadmium, zinc chloride, osmium tetroxide, and vanadium, can cause injury to the entire tracheobronchial tree and generally do not produce upper airway obstruction as the initial presentation. Bronchiolitis and pulmonary edema are common, ultimately leading to bronchiolitis obliterans. Cadmium, for example, can cause diffuse emphysema and severe airway obstruction but only minimal fibrosis. During the exposure, no symptoms may be present, tracheobronchitis with cough and shortness of breath may be noted, or immediate acute pulmonary edema may occur. The symptoms can progress rapidly, but commonly the initial symptoms resolve and are followed by a period of minimal symptoms (cough) lasting up to 48 hours. Fever, myalgias, dyspnea, and progressive hypoxemia then occur, and the radiographic picture is that of pulmonary edema. These severe symptoms can resolve, only to recur 2 to 5 weeks later and lead to progressive bronchiolitis obliterans. The initial step of removing the victim from the noxious environment is usually sufficient to treat mild exposures. The prognosis for more severe toxic gas exposures varies with duration and extent of exposure. Because improvement after the initial exposure may be temporary, close observation for 48 hours after the exposure is advisable. Oxygen is toxic to the lungs when used in high concentrations for prolonged periods. This toxicity occurs clinically in patients in intensive care units who are on mechanical ventilators. The toxic effects of hyperoxia are believed to result from excessive generation of superoxide, an unstable free radical produced by the single electron reduction of oxygen. Superoxide is produced as a normal by-product of oxidative metabolism and scavenged by the protective enzymes, the superoxide dismutases, that catalyze its dismutation to hydrogen peroxide. If it is not scavenged enzymatically, superoxide anion can donate an electron to hydrogen peroxide in the presence of transition metals. Hydroxyl radical is highly reactive and can initiate lipid peroxidation and oxidize protein and nucleic acids. In the adult, the major sites of oxygen injury are the alveolar epithelium and the capillary endothelium. Advanced injury destroys the capillary bed with resultant interstitial and alveolar edema, hypoxemia, and sometimes death. Oxygen toxicity usually occurs in acutely ill patients who are receiving oxygen in high concentrations and mechanical ventilation for lung injuries that obscure the onset of pulmonary toxicity. Lung compliance progressively falls; the alveolar-arterial oxygen gradient gradually widens, and increasing concentrations of oxygen are needed to maintain adequate oxygenation of arterial blood. A dry, hacking cough and substernal pain may occur after 6 to 12 hours of breathing pure oxygen.
Dactinomycin also causes significant gastrointestinal toxicity with abdominal cramps and diarrhea as well as mucositis gastroenteritis flu buy cheap nexium 20mg line. The drug also can cause a radiation "recall" reaction in which cutaneous erythema redevelops at a site of prior irradiation gastritis symptoms throat 20mg nexium sale. It has some utility in adults in third-line therapy of germ cell tumors of the testis or ovary gastritis diet 6 pack effective 40mg nexium, gestational choriocarcinoma chronic gastritis low stomach acid cheap 40 mg nexium free shipping, and soft tissue sarcomas. Two inhibitors of this enzyme have now been approved for clinical use: irinotecan and topotecan. The dose schedule used most commonly is a single infusion (200 mg/m2) every 3 weeks, although other dose schedules are being explored. The principal dose-limiting toxicities are non-hematologic, in particular diarrhea. Diarrhea may be seen within the first 24 hours of treatment, or later, occurring 4 to 8 days after treatment. Aggressive treatment with loperamide or octreotide at the first sign of diarrhea has allowed patients to tolerate this drug. Current studies are evaluating combinations of this drug with fluorouracil or raltitrexed (Tomudex), an investigational drug that targets the enzyme thymidylate synthase. Topotecan (Hycamtin) is approved for use in previously treated patients with ovarian cancer. Its mechanism of action is similar to that of irinotecan, namely, inhibition of topoisomerase I. Topotecan also has activity in other tumors, including hematologic malignancies, small cell lung cancer, neuroblastoma, and rhabdomyosarcoma. The dose limiting and most common toxicity is myelosuppression, especially neutropenia. Procarbazine is usually given in a dose of 100 mg/m2 /day for 10 to 14 days in each chemotherapy cycle. Procarbazine is activated metabolically to produce a methyldiazonium ion that binds to nucleic acids, proteins, and phospholipids to inhibit macromolecular synthesis. Patients taking procarbazine may develop hypertension if they ingest tyramine-rich foods such as ripe cheese, wine, and bananas. Disulfiram-like reactions are also seen, with sweating and headache after alcohol ingestion. A methyl carbonium ion metabolite is thought to be the cytotoxic intermediate with alkylating activity. Dacarbazine is administered intravenously either in a single-day infusion schedule of 750 mg/m2 or in fractionated bolus doses over 5 days or more. This agent is available only in an oral formulation because of its sparing solubility. The gastrointestinal distress increases with daily use, limiting the length of treatment courses (at doses of up to 12 mg/kg/day) to 2 to 3 weeks. At high dosage, a megaloblastic anemia can develop, which is non-responsive to vitamin B12 or folic acid. Gastrointestinal side effects of nausea and vomiting are also common with high-dose therapy. Mitoxantrone (Novantrone) is an anthracenedione with a structure that appears analogous to that of the anthracyclines. In terms of cellular response by tumor cells, there is not complete cross-reactivity between mitoxantrone and the anthracyclines. Comparative studies in patients with advanced breast cancer suggest that it is less active and less toxic than doxorubicin. Gastrointestinal side effects, including nausea, vomiting, and mucositis as well as alopecia, are less severe than with the anthracyclines. Mitoxantrone can cause some cardiac toxicities, usually manifest by development of arrhythmia at the time of injection, and can exacerbate pre-existing anthracycline-induced cardiomyopathy. It can be used intraperitoneally in patients with ovarian cancer, because most of the drug remains in the peritoneal cavity. This approach reduces systemic toxicity, but it can induce chemical peritonitis and adhesions. L-Asparaginase (Crasnitin, Elspar) is a bacterial enzyme isolated from Escherichia coli or Erwinia carotovora. Its major use is to treat lymphoblastic leukemias and some lymphomas with a deficiency in asparagine synthetase and cellular dependence on exogenous asparagine.
