Meticulous oral hygiene assists in preventing or lessening the deleterious effects of mucositis spasms sentence colospa 135 mg purchase on-line. Older children can cleanse their own teeth and gums with a soft toothbrush and use a saline-based oral solution to rinse the mouth. Because orthodontic appliances may harbor debris and cause infection, these appliances may need to be removed during chemotherapy. Nursing management of the child with mucositis involves implementing an oral hygiene regimen, monitoring hydration, and encouraging the child to choose foods that are best tolerated. Prevention of infection and treatment of pain are the main objectives in treating oral mucositis. Daily oral care, antiseptics, topical anesthetics, coating agents, lubricants, mechanical debridement, and miscellaneous agents are used. Fluid intake can be facilitated by the use of a straw to bypass tender oral mucosa. Anorexia is expected in these children, and as the ulcerations heal, they will start to eat and drink normally. Subsequent chemotherapy regimens may require dose modification to prevent similar episodes.

Nurses play a key role in assessment of the oral cavity during childhood cancer treatment. Challenges to accurate oral assessment are numerous when caring for children who are often uncooperative. The need for assessment tools that are simple, quick to complete, and easy to use to assess most children is evidence in the literature. The lack of validated oral assessment instruments for infants, for children with cancer stresses the need for future research studies. The qualitative findings indicate that fatigue is defined differently by children, adolescents, and their parents49,50,51 and that different types of fatigue exist in pediatric oncology patients. Adolescents with the cluster of increased fatigue and sleep disturbances experienced more depressive symptoms and behavior changes. One mechanism contributing to cancer-related fatigue involves abnormalities in adenosine triphosphate synthesis P. These include pharmacologic measures, sleep hygiene education, schedules for regular physical activity, and distraction techniques. Pain Management One of the most important roles of the nurse is the assessment and management of pain in children with cancer (see also Chapter 42).

Hypercalcemia of malignancy has been documented in almost every type of childhood cancer but is most commonly seen in hematologic malignancies spasms in your stomach discount colospa 135 mg with amex, rhabdomyosarcoma, and neuroblastoma. Hypervitaminosis A or D, granulomatous disease, adrenal insufficiency, and fractures may also contribute. Early nonspecific symptoms are often gastrointestinal: nausea/vomiting, anorexia, and constipation Table 38. Increasing serum calcium levels lead to profound muscle weakness, renal insufficiency, bradyarrhythmias, and coma. Treatment has four components: hydration, increasing the renal calcium excretion, decreasing the calcium mobilization from bone, and treatment of the underlying malignancy. Forced diuresis requires monitoring of intravascular volume and serum and urine electrolytes; profound fluid shifts and potassium and magnesium losses may accompany sodium, calcium, and fluid excretion. Medications that exacerbate hypercalcemia of malignancy; such as thiazide diuretics, oral contraceptives, tamoxifen, vitamin D, retinoic acid, antacids with calcium carbonate, and lithium, should be avoided. Calcitonin, mithramycin, and gallium nitrate, traditional therapies for hypercalcemia, have fallen out of favor with the development of the bisphosphonates. Bisphosphonates inhibit osteoclast-mediated resorption of bone and reduce osteoclast viability. Although most data exist in adults, the literature on their use in the pediatric population is growing. Oral bisphosphonates are also now available, but pediatric experience with them is limited. A rapid fall in the serum sodium level to below 125 mmol/L within 24 hours or a gradual decrease in serum sodium to less than 115 mmol/L can be life-threatening. Evaluation and Differential Diagnosis Most hyponatremia is asymptomatic and is usually diagnosed by routine laboratory evaluation. Early symptoms include fatigue, headache, nausea, and myalgias; later manifestations are lethargy, confusion, hallucinations, seizures, and coma. Hypothyroidism, heart failure, acute renal failure, pancreatitis, and use of diuretics may exacerbate hyponatremia. Diabetes insipidus occurs in children with Langerhans cell histiocytosis or with suprasellar tumors, either from the tumors or after tumor resection. Diabetes insipidus usually presents with polydipsia, polyuria, and hypernatremic volume depletion; however, if the patient has been replacing losses with water or other hypotonic solutions, hyponatremia may develop. In cases of acute, severe symptomatic hyponatremia, 3% hypertonic saline should be infused to replace sodium losses, and some advocate addition of furosemide to diurese free water.

Antiepileptic Drugs Traditional anticonvulsants spasms near gall bladder buy colospa 135 mg low cost, such as carbamazepine and valproic acid, are believed to relieve chronic pain by blocking calcium channels at the cellular neuronal level, thereby suppressing spontaneous electrical activity and restoring the normal threshold to depolarization of hypersensitive nociceptive neurons, without affecting normal nerve conduction. These medications are particularly useful in patients with labile mood disorders and neuropathic pain. Anticonvulsant medications generally have gastrointestinal side effects in addition to sedation, anemia, ataxia, rash, and hepatotoxicity. In addition, carbamazepine and oxcarbazepine are associated with an increased incidence of potentially fatal Stevens-Johnson syndrome. These medications have narrow therapeutic windows and may have extreme variability in therapeutic blood medication levels as well as multiple drug-drug interactions. These concerns are particularly cogent in the cancer population; therefore, less toxic drugs should always be tried first. Drug levels should be obtained with each dose increase and periodically thereafter. Carbamazepine, in particular, autoinduces hepatic microsomal enzymes, which can further complicate obtaining a therapeutic medication level. Frequent pregnancy tests are useful with menstruating female adolescents taking valproic acid, because severe neural tube defects are associated with this medication. While these newer agents have their own, and sometimes troubling, side effect profiles, they are far less toxic than their predecessors. They do not require monitoring of liver function, bone marrow function, or therapeutic blood levels. Studies using gabapentin to treat chronic headaches, reflex sympathetic dystrophy, and chronic regional pain syndrome have shown great promise. It is theorized that it increases gabaminergic transmission and decreases glutaminergic transmission while binding to the voltagedependent calcium channels, producing antineuralgic effects, and inhibiting spontaneous and inappropriate discharge of nociceptive fibers. Interestingly, children demonstrate side effects not reported in adults-severe impulsive or oppositional behavior, agitation, and occasionally depression. Because it undergoes virtually no hepatic metabolism, it has no significant drug interactions, a concern in patients with chronic pain who frequently take multiple medications, which are for both pain and the underlying medical or surgical condition causing the pain. Because it is eliminated by the kidneys, dosing adjustment must be made for patients with renal impairment. However, topiramate very frequently results in cognitive dysfunction and short-term memory loss, particularly problematic with school-aged children. Pediatricians who dose this medication should consider its effects on school performance. The pediatrician should also be aware that in female adolescents topiramate is associated with anorexia and weight loss-frequently a desirable side effect except in the cancer patient- whereas other anticonvulsants are typically associated with appetite stimulation and weight gain.

A diet high in magnesium or potassium may be useful for the child with excessive urinary losses of minerals because of chemotherapies or antibiotics muscle relaxant with ibuprofen buy cheap colospa. Calorie supplementation may be required to assist with weight gain or weight maintenance during cancer treatment. This can be accomplished with usual foods, or in combination with commercial supplemental drinks or calorie additives. Some children, particularly long-term survivors of cancer with activity limitations, may be aided by the instruction of moderate calorie and low-fat diet principles when obesity is a concern Table 41. Enteral Feeding If children are unable to meet their nutrient needs orally, tube feedings should be considered as a means of preserving or obtaining optimal nutritional status. In children newly diagnosed with cancer, nasogastric tube feedings have been given in addition to volitional oral intake with successful weight gain. One group demonstrated improved weight gain in 21 patients, compared with 8 children receiving dietary counseling alone. There was a positive correlation between increases in weight and mid-arm circumference and the duration of enteral feedings. However, 8 of the 21 patients stopped feedings after 10 days because of vomiting or diarrhea. Of their 49 evaluable patients, 86% were maintained on enteral nutrition alone, including 8% who took adequate oral intake. Cholestasis occurred significantly less often in children who received at least some tube feeding compared with children who were exclusively parenterally fed; nutritional costs were also less in children receiving tube feeding. Gastrostomy tube feedings are generally considered to be more cosmetically acceptable and more comfortable than nasogastric feedings, while still providing the same advantages over parenteral nutrition. The use of surgically placed or percutaneous endoscopic gastrostomy feedings in pediatric patients with cancer has been examined by several groups. Almost all the groups documented that the majority of patients maintained or gained weight with percutaneous endoscopic gastrostomy feeds. Severe complications, such as systemic infections, were a rarity and not observed in all studies. Minor complications were noted, and included leakage of gastric juice leading to site irritation, bleeding at the site, and superficial infections. Adapted from Excerpt of the Report of the Dietary Guidelines Advisory Committee on Dietary Guidelines for Americans, 2000, United States Department of Agriculture. Most pediatric patients with cancer will tolerate intact protein, 1 kcal/mL formulas either orally or via tube feeding. Formulas with elemental (free amino acids) or semielemental (small peptides) protein are available, primarily for the purpose of allergy or intolerance. Medium chain triglycerides are also used in many formulas intended for patients with fat malabsorption. An abundance of defined formula diets are available for varying conditions and ages. Parenteral Feeding When the gastrointestinal tract is nonfunctional or unavailable, nutrients may be infused via central venous catheters.

The absence of oral lesions cannot be used to discount the presence of esophageal candidiasis in neutropenic patients spasms vitamin deficiency colospa 135 mg sale. Although esophagoscopy with mucosal biopsy is the most definitive method for establishing a diagnosis, this may not be feasible, practical, or safe in many children. Accordingly, an empirical approach is often warranted in children with suspected esophageal candidiasis. Initial therapy with fluconazole is often effective; however, failure to symptomatically respond promptly is an indication for empirical amphotericin B or an echinocandin for treatment of possible azole-resistant Candida species. Echinocandins have been extensively studied experimentally and clinically in treatment of esophageal candidiasis due to fluconazole-susceptible and fluconazole-resistant Candida species. If the patient symptomatically responds to acyclovir, antiviral therapy should be given for 7 days. For example, obstructive lesions may be caused by primary or metastatic cancer, cholangitis or a conjugated hyperbilirubinemia may be caused by extrahepatic biliary obstruction by tumor, and chronic abdominal pain or diarrheal syndromes may be secondary to bowel wall infiltration by malignant disease or infection. Intraabdominal pain must be expeditiously evaluated with a thorough physical examination. Repetitive rectal examinations must not be performed in the neutropenic patient, because bacteremia and local infection may result. Appropriate studies include routine hematologic and serum chemistry values, amylase, total and direct bilirubin, and flat and upright abdominal radiographs. Invasive diagnostic or radiographic procedures such as barium enema and endoscopy should be avoided in the neutropenic patient. Typhlitis or neutropenic colitis is a necrotizing infection of the cecum restricted almost entirely to cancer patients. Patients most often present with subacute or acute onset of right lower quadrant abdominal pain and tenderness, which frequently becomes generalized over several hours, with fever, diarrhea, and prostration. As fever may be absent early in the course of neutropenic colitis, the presence of abdominal pain in a neutropenic patient should prompt the administration of empirical antibacterial therapy for aerobic and anaerobic pathogens. The etiologic agents responsible for typhlitis include anaerobes and gram-negative bacilli, especially P. Optimal management initially involves supportive care, including nasogastric suction, adequate fluid replacement, and adjustment of antimicrobial therapy to cover resistant gram-negative and anaerobic species. However, if typhlitis develops in a patient who has diarrhea and has received previous antibacterial therapy, then ceftazidime or cefepime plus metronidazole is the logical choice. Although the cecum is the most common site of infection, abnormalities may extend beyond this region. Aggressive surgical intervention to resect necrotic bowel may be beneficial for a subset of patients, and the timing of such intervention is critical. A high index of suspicion is necessary because of the occurrence of similar abdominal symptoms in oncology patients receiving chemotherapy or periabdominal radiation. Oncology patients with diarrhea with or without fever and abdominal pain should be evaluated with routine stool cultures and a C.

The imidazole of histidine is an intracellular protein buffer involved in maintaining intracellular pH spasms below left breast order 135 mg colospa overnight delivery. Simply put, the alpha-stat strategy aims to maintain intracellular function by maintaining intracellular pH (not blood pH) and enzymatic function. However, there are important considerations for patients on hypothermic cardiopulmonary bypass. Carbon dioxide shifts the oxyhemoglobin dissociation curve to the right, which helps counteract the left shift caused by hypothermia. Carbon dioxide is also a powerful cerebral vasodilator and pulmonary vasculature vasoconstrictor. Patients receiving hypothermic bypass with pH-stat management may therefore benefit from improved offloading of oxygen at the tissue level, increased cerebral blood flow and improved cooling of the brain. A decreased run off of blood to the pulmonary circulation is especially important for patients with known or even undiagnosed aortopulmonary collaterals. Additionally, pH-stat management, with its low pH at deep hypothermia, suppresses the cerebral metabolic rate which may prolong oxygen availability during periods of circulatory arrest [12]. This is usually quantified with a reliable temperature probe location, which approximates the brain temperature. A tympanic temperature may be ideal, but the venous blood temperature may be more practical to use for temperature correction since it is not affected by user placement and other artifact as much and is therefore more reliable. As with all blood gas management strategies, an in-line blood gas monitor that supplies real time data is essential for tight control of values during bypass. To note, the carbogen method limits one to the hyperoxic oxygen strategy since blended gas is not utilized. Additionally, it may be possible to provide pH-stat management simply by using very low sweep gas flow on bypass. It is important to note that when carbogen systems are utilized in neonates and for deep hypothermia cases in particular, this sweep flow relationship may change. This should be taken into consideration regardless of the blood gas strategy utilized. Crossover strategy for carbon dioxide management Some clinicians believe that the primary benefits of pH-stat blood gas management are increased cerebral blood flow and improved brain cooling. Additionally, the primary benefits of alpha-stat blood gas management are preservation of intracellular buffering and enzymatic function. These divergent strategies are most pronounced during deep hypothermia with or without circulatory arrest. Some institutions try to extract the benefit of both techniques by using pH-stat to cool the patient with a crossover to alpha-stat for maintenance at low flow bypass or prior to planned circulatory arrest. However, prospective randomized human clinical trials supporting this crossover strategy have not been performed.

There is diffuse papillary hyperplasia of the thyroid epithelium and lymphoid aggregates spasms with spinal cord injury order 135 mg colospa amex, which are typical for Graves disease. Propylthiouracil and methimazole inhibit thyroid peroxidase, thereby inhibiting iodide oxidation and blocking its addition to the thyroglobulin protein. There is diffusely increased uptake in the thyroid, which is typical for Graves disease. Thyroid storm can rarely complicate Graves disease; this involves malignant hyperthermia and heart failure. Thyroid ophthalmopathy can involve a combination of proptosis and lid lag as a result of the increased sympathetic stimulation of the levator palpebrae superioris muscle and the periorbital deposition of hydrophilic mucopolysaccharides and fibrosis. There is a discrete nodule of red-brown thyroid that is consistent with a benign adenoma. Graves disease, toxic multinodular goiter, and hyperfunctioning thyroid carcinoma can also produce hyperthyroidism. This "cold" nodule is making less colloid and taking up less iodine than the surrounding thyroid. Most solitary nodules in the thyroid are benign tumors, cysts, or inflammatory lesions (benign neoplasms outnumber malignant neoplasms by 10:1), but a cold nodule has a greater likelihood of being malignant. Without the invasion of the capsule or the vasculature, this lesion is likely to be a benign follicular adenoma. The papillary pattern and the empty-appearing nuclei are typical for papillary carcinoma of the thyroid. Additional features include psammoma bodies and, at higher magnification, nuclei with a ground-glass appearance. Although this tumor is clearly not making thyroid hormone, there must be a sufficient amount of remaining normal thyroid gland to maintain a euthyroid state. Exposure to ionizing radiation, particularly during the first two decades of life, is a risk for thyroid carcinoma. The nodal lesion is probably a metastasis, so this is a malignant thyroid tumor, most likely papillary carcinoma (75% to 85% of malignant thyroid tumors are papillary carcinomas, 10% to 20% are follicular carcinomas, 5% are medullary, and <5% are anaplastic). Despite metastasis, the prognosis remains good, with a 10-year survival rate of more than 95%. Thyroiditis with granulomatous inflammation and giant cells is present; this is consistent with de Quervain thyroiditis. There is transient hyperthyroidism from the disruption of thyroid follicles and the release of hormone. Typically, after the resolution of the inflammation, completely normal thyroid function returns.
