Intestinal anthrax: Presents with abdominal pain, vomiting, and bloody diarrhea Bacteremic and intestinal anthrax are rare to occur Laboratory diagnosis: Specimen: Fluid or pus from skin lesion, Blood, sputum Smear: Non-capsulated gram-positive rods with centrally located spores from culture Large capsulated gram-positive rods with out spores from primary specimen. Non-hemolytic,large, dense, grey-white irregular colonies with colony margin of “Medussa Head” or “curled-hair lock” appearance due to composition of parallel chaining of cells. Biochemical reaction: Gelatin-stab culture: Gelatin liquefaction Growth along the track of the wire with lateral spikes longest near the surface Providing “inverted fur tree” appearance. Ocular infection Ocular disease following trauma from non-sugical penetrating objects 196 Manifests with keratitis, endophthalmitis, and panophthalmitis Treatment: Clindamycin + Aminoglycosides 2. Genus: Clostridium Characteristics: • Clostridia are anaerobic, spore-forming motile, gram-positive rods. PhospholipaseC (α toxin) It has lethal, necrotizing and hemolytic effect on tissue. It causes cell lysis due to lecithinase action on the lecithin which is found in mammalian cell membrane. Clostridial food poisoning It causes secretory diarrhea due to release of enterotoxin in the intestine Self-limiting diarrhea similar to that produced by B. Saccharolytic property showing reddening of the meat with a rancid smell due to carbohydrate decomposition. Proteolytic property showing blackening of the meat with unpleasant smell due to protein decomposition. Nagler reaction: Lecithinase C activity- Opacity in the egg-yolk medium due to lecithin break down 199 Procedure: 1. Treatment: Penicillin Prompt and extensive wound debridement Polyvalent antitoxin Prevention and control Early adequate contaminated wound cleansing and debridement 200 Closridium difficile General characteristics:. Not frequently found in the healthy adult, but is found often in the hospital environment. Human feces are the expected source of the organism Pathogenesis and clinical features: Administration of antibiotics like ampicillin, clindamycin and cephalosporins results in killing of colonic normal flora and proliferation of drug resistant C. Dignosis: Identification of toxin A and B in feces by latex agglutination test Treatment: Dicontinuation of offending drugs Administration of metronidazole or vancomycin 201 Clostridium tetani General characteristics: • World wide in distribution in the soil and in animal feces • Longer and thinner gram-positive rods with round terminal spores giving characteristic “drum-stick” appearance. Tetanolysin: Hemolytic property Pathogenesis and Clinical manifestation: Infection of devitalized tissue (wound, burn, injury, umblical stamp, surgical suture) by spores of C. Muscle spasm and rigidity Laboratory diagnosis: The bacteria can be cultured in a media with anaerobic atmosphere. The toxin is absorbed from the gut and acts by blocking the release of acetylcholine at synapses and neuromuscular junction and manifests with flaccid paralysis and visual disturbance, inability to swallow, and speech difficulty Death is secondary to respiratory failure or cardiac arrest 2. Treatment: Administration of intravenous trivalent antitoxin ( A,B,E) Mechanical ventilator for respiratory support Prevention and control:.

Congestive heart failure is treated with diuretics discount confido 60 caps visa prostate cancer young, digoxin, and afterload reduction when it can be tolerated. Great care must be taken in patients with aortic stenosis to avoid overdiureseis or too much preload reduction (with nitroglycerine and diuretics), which can result in inadequate filling of the left ventricle and subsequent syncope or low output. Heart rate must be controlled with beta-blockers digoxin or calcium channel blockers to permit adequate chamber filling, espe- cially when stenotic lesions are present. Anticoagulants are needed for patients in atrial fibrillation to prevent systemic embolization. There is some evidence that the use of the calcium channel blocker Procardia in asymptomatic patients with aortic insufficiency may delay their need for surgery. Once diagnostic studies have been completed, recommendations for chronic medical therapy or surgery are made. Heart Murmurs: Acquired Heart Disease 275 must be made on an individual basis and must involve an informed consent from the patient and family. Medical therapy is used for those patients when it is believed the surgical risk is too high or their long-term benefit is not sufficient for surgery. Others who are not yet ready for surgery receive medical therapy but are followed closely until indications for surgery become manifest. As noted, the surgical management of valvular heart disease is dependent on the risk-benefit ratio for the patient. Unfortunately, this is not always so clear when the risk of the operation is high and the benefit to an individual patient not clear. However, generalized indi- cations for surgery have evolved based on short- and long-term outcome studies. Detailed diagnostic and therapeutic guidelines are well summarized in “Consensus Statement on Management of Patients with Valvular Heart Disease,” developed by a combined task force of the American Heart Association and the American College of Cardiology. Any patient with symptomatic aortic stenosis should undergo valve replacement unless there are significant contraindica- tions or the patient’s life expectancy is otherwise severely limited. Even those patients with significant organ dysfunction secondary to the low output state may be considered. In the past, it also was believed those asymptomatic patients with aortic stenosis and a valve area of less than 1cm2 or a gradient >60mmHg also should undergo valve replacement. More recently, with the ability to follow patients closely with echocar- diography, surgery may be delayed until symptoms develop without increased risk to the patient as long as surgery occurs rapidly fol- lowing the onset of symptoms. Studies have shown that a patient with aortic insufficiency and a normal ven- tricle can undergo replacement with little surgical risk. On the other hand, once the ventricle begins to fail, the risk increases dramatically. Even in the absence of symptoms, increased operative mortality occurs in the presence of indicators of deteriorating ventricular function. At the present time, valve replacement is the recommended treat- ment for surgical correction of aortic valvular diseases. There are a few patients with aortic insufficiency in whom valvuloplasty has been successful, although replacement remains the standard. Spotnitz Mitral Stenosis and Mitral Insufficiency Mitral valve disease is different from aortic valvular disease in that reconstructive surgery often can be done instead of replacement of the valve. The operative mortality has been less with a repair when the long-term risks of a prosthetic valve are avoided. Mitral stenosis was the first valve problem approached surgically and was performed suc- cessfully in the late 1940s several years before the first successful use of the heart lung machine (by Gibbon3 in 1953). In any case, either direct commissurotomy and reconstruction, if needed, of the subvalvular apparatus are performed, or valve replacement is done. Because of the success of mitral valvuloplasty for mitral stenosis and the detailed diagnostic images of the valves now obtainable by echocardiography, certain patients with mitral stenosis are treated using percutaneous methods in the catheterization laboratory using balloon dilators (larger balloons but similar technique to angioplasty) with good success. Surgical treatment of mitral insufficiency is the most difficult con- dition about which to make decisions. Many patients are without symptoms despite large amounts of regurgitation and decreased left ventricular function.

The patient must cope with the constant fear of a seizure and the psychological consequences (Rho et al confido 60 caps cheap androgen hormone 24. Children with epilepsy may be ostracized and excluded from school and peer activities. These problems are compounded during adolescence and add to the challenges of dating, not being able to drive, and feeling different from other people. Adults face these problems in addition to the burden of finding employment, concerns about relationships and childbearing, insurance problems, and legal barriers. Family reactions may vary from outright rejection of the person with epilepsy to overprotection. As a result, many people with epilepsy have psychological and behavioral problems. Counseling assists the patient and family to understand the condition and the limitations it imposes. Nurses can improve the quality of life for patients with epilepsy by teaching them and their families about symptoms and their management (Bader & Littlejohns, 2004). Providing Patient and Family Education Perhaps the most valuable facets of care contributed by the nurse to the person with epilepsy are education and efforts to modify the attitudes of the patient and family toward the disorder. The person who experiences seizures may consider every seizure a potential source of humiliation and shame. This may result in anxiety, depression, hostility, and secrecy on the part of the patient and family. Ongoing education and encouragement should be given to patients to enable them to overcome these reactions. The patient with epilepsy should carry an emergency medical identification card or 376 wear a medical information bracelet. The patient and family need to be educated about medications as well as care during a seizure. Monitoring and Managing Potential Complications Status epilepticus, the major complication, is described later in this chapter. The patient and family are instructed about side effects and are given specific guidelines to assess and report signs and symptoms that indicate medication overdose. A complete pharmacologic profile should be reviewed with the patient to avoid interactions that either potentiate or inhibit the effectiveness of the medications. Promoting Home and Community-Based Care Teaching Patients Self-Care Thorough oral hygiene after each meal, gum massage, daily flossing, and regular dental care are essential to prevent or control gingival hyperplasia in patients receiving phenytoin (Dilantin). The patient is also instructed to inform all health care providers of the medication being taken, because of the possibility of drug interactions. An individualized comprehensive teaching plan is needed to assist the patient and family to adjust to this chronic disorder. Continuing Care Because epilepsy is a long-term disorder, the use of costly medications can create a significant financial burden. This organization also serves as a referral source for special services for people with epilepsy. State vocational rehabilitation agencies can provide information about job training. If seizures are not well controlled, information about sheltered workshops or home employment programs may be obtained. Federal and state agencies and federal legislation may be of assistance to people with epilepsy who experience job discrimination. As a result of the Americans with Disabilities Act, the number of employers who knowingly hire people with epilepsy is increasing, but barriers to employment still exist (Bader & Littlejohns, 2004). Patients and their families need to be reminded of the importance of following the prescribed treatment regimen and of keeping follow- up appointments. In addition, they are reminded of the importance of participating in health promotion activities and recommended health screenings to promote a healthy lifestyle.
