The goals of calcium-lowering therapy are to (a) lower the corrected calcium to normal levels, (b) regain fluid and electrolyte balance, (c) relieve symptoms, and (d) prevent life-threatening complications. Patients who are refractory to available therapies may have calcium-lowering therapy withheld (usually resulting in coma and death), which may be a humane approach. 36 general approach to treatment therapeutic options for the treatment of hypercalcemia should be directed toward the level of corrected serum calcium and the presence of symptoms (figure 99–4).

The multinational association for supportive care in cancer (mascc) has validated a risk assessment tool that assigns a risk score to patients presenting with fn (table 99–6). 16 patients with a risk-index score greater than or equal to 21 are identified as low risk and are candidates for outpatient therapy (discussed under section treatment).

Ldh, lactate dehydrogenase. From lyman gh, lyman ch, agboola o. Risk models for predicting chemotherapy-induced neutropenia. Oncologist. 2005;10:427–437. Three primary modalities for preventing infection in patients who are expected to become neutropenic have been utilized, the first of which is the least expensive and simplest. •• vigilant hand hygiene •• prophylactic antibiotics •• colony-stimulating factors (csfs) the advantages and disadvantages of these strategies are discussed individually in the following sections. Hand hygiene as previously discussed, most infections in neutropenic patients are a result of endogenous flora. However, prevention of further acquisition of environmental pathogens is also important. Patients who are or will become neutropenic should practice careful handwashing and avoid contact with people who neglect hand hygiene. In addition, ingestion of certain fresh fruits and vegetables as well as unprocessed dairy products should be avoided during the neutropenic period. Practitioners should also engage in vigilant hand hygiene after each patient encounter to limit the spread of infections between patients. 18 1468  section 16  |  oncologic disorders clinical presentation and diagnosis of fn17,18 general •• only 50% of patients with fn have a clinically documented infection. •• only 25% of patients with fn have a microbiologically documented infection. Signs and symptoms •• fever is typically the only sign of infection, although septic patients may have chills. •• infected catheter sites may be erythematous and tender to the touch. Laboratory tests •• cbc with differential •• two blood cultures from each access site (peripheral and central), urinalysis, urine culture, chest x-ray, sputum cultures other diagnostic tests •• detailed physical examination of the oral mucosa, sinuses, skin, catheter access sites, perineal area (no rectal examination because of the risk of bacteremia) prophylactic antibiotics routine antibacterial prophylaxis is controversial and has been attempted primarily with sulfamethoxazole–trimethoprim (smztmp) and quinolones. Smz-tmp offers improved prophylaxis against gram-positive organisms compared with quinolones. Quinolones are more effective prophylaxis against gram-negative infections.

A nighttime dose of a comt inhibitor may improve rls. 2,6,16 autonomic and other problems drooling may be accompanied by speech problems and dysphagia. Ach, botulinum toxin injections, and sublingual atropine can decrease drooling. Nausea improves if pd medications are taken with meals and with antiemetic therapy (eg, domperidone or trimethobenzamide). Sexual dysfunction or urinary problems may require further evaluation. Adjustment of pd therapy to increase on time, removal of drugs that decrease sexual response, and pharmacologic therapy (eg, sildenafil) may improve sexual dysfunction. Studies of sexual dysfunction in women with pd are lacking. Patients with urinary frequency may find a bedside urinal and a decrease in evening fluid intake helpful. Improvement in pd 516  section 5  |  neurologic disorders symptom control can decrease urinary frequency, but worsening symptoms may require catheterization or pharmacologic measures (eg, oxybutynin, tolterodine, propantheline, imipramine, hyoscyamine, or nocturnal intranasal desmopressin). Anticholinergic drugs can cause urinary retention and constipation. Constipation can be improved by increased fluid intake, a fiber-rich diet, probiotics, and physical activity. Stool softeners, osmotic or bulk-forming laxatives, glycerin suppositories, or enemas may help, while cathartic laxatives should be avoided. Dyskinesia-related sweating may respond to pd therapy adjustment or β-blockers. Treating orthostasis includes the removal of offending drugs (eg, tricyclic antidepressants, pd medications, alcohol, and antihypertensives) increasing carbidopa doses, increased salt or fluids to the diet, compression stockings, fludrocortisone, indomethacin, or midodrine. Droxidopa, a norepinephrine synthetic precursor, was recently approved for treating orthostatic hypotension associated with pd. 38 seborrhea usually responds to over-the-counter dandruff shampoos or topical steroids. 2,6,10,17 treatment of response fluctuations as the disease progresses, most patients develop response fluctuations.

Dizziness a nd ver t igo treatment, although there is limited evidence o benef t. Furthermore, and some authors eel the decreased perusion to the labyrinth may be detrimental.21 similarly, other authors believe an increased water intake may be benef cial as well.22 for patients with re ractory symptoms, intratympanic steroids and/or gentamicin have been indicated as well as pressure treatments with the meniett device, and endolymphatic sac surgery. Each o these treatments has a potential role, but ultimately or patients requiring labyrinthectomy, the e ectiveness o each o these was similar.23 central causes of vertigo dizziness and vertigo may result rom central nervous system (cns) dys unction. T e onset, duration, and accompanying clinical signs and symptoms help distinguish peripheral vertigo rom central neurologic causes o vertigo. As previously discussed, hearing loss, tinnitus, and aural ullness are requent symptoms associated with peripheral vestibular dys unction. Localizing neurologic ndings indicate the need to investigate or cns pathology. Central vestibular dys unction tends to produce a variable clinical picture due to the diverse pathological conditions o the central nervous system. In comparing and contrasting peripheral and central vertigo, central vertigo tends to produce a more severe imbalance with direction-changing nystagmus, rare hearing loss, and slow rates o recovery. T is is in direct contrast to most orms o peripheral vertigo, which tend to cause moderate levels o imbalance, direction- xed nystagmus, requent hearing loss, and more rapid rates o recovery. T e most common cause o central vertigo is vestibular migraine, which is also known as migraine-associated dizziness. Most patients with vestibular migraine present with spontaneous attacks o vertigo lasting 5 minutes to 3 days. Patients may also have vertigo induced by position changes, head movement, or visual stimuli.24 headache may be absent during acute attacks. During the acute phase, the patient may have central spontaneous or positional nystagmus. I seen between attacks, the physical examination may be normal. Some patients may have otological symptoms as noted earlier. A amilial history is o en positive as well.25 recent research into vestibular migraine has elucidated common central pathways or vestibular and nociceptive in ormation processing as well as shared expression o receptors typically targeted by antimigrainous medications.26 patients with vestibular migraine seem to have a hypersensitive vestibular system. Riggers or symptoms can include oods such as tryptophans, medications, lack o sleep, alcohol, and emotional stress. Migraine patients are at an increased risk o stroke, particularly emale patients with aura. A recent study demonstrated an increased level o endothelial microparticles in the circulation o emale migraine patients with aura.
