Page 268 CSF analysis (Table 6.2) a) Specimens: Send fluid for laboratory studies, including electrolytes, glucose, protein, cell count and differential, Gram's stain, and cultures Label the tubes as follows: ''#1 Culture," "#2 Chemistries," and "#3 Cell count." Send specimens to the laboratory immediately b) Appearance: Record the color and clarity of the fluid Note the presence of coagula, pellicles, or sediment Time required for the formation will vary with different diseases Table 6.2 Cerebrospinal Fluid Laboratory Values Condition CSF pressure Glucose level Cytology Predominant leukocyte Increased Normal Rare Mononuclear Normal Rare Mononuclear Disease related Tumor Meningeal carcinomatosis Decreased Infectious related Bacterial meningitis Increased Decreased None Neutrophil Cryptococcal meningitis Increased Increased Decreased Normal None Lymphocyte Epidural abscess Decreased Normal None Lymphocyte V Microbiology A Organism staining: To identify microorganisms under the microscope, staining is a critical element The three stains most commonly used are the Gram's stain, acid-fast stain, and India ink stain The techniques that provide the best results are thin smears, allowing smears to dry before they are fixed (heating wet smears distorts the organisms and cells), and fixing smears with heat by Page 269 quickly passing the slide through a flame The slide should not be stained until it cools Gram's stain a) Place gentian violet on the slide for one minute, and wash with running water b) Flood with iodine solution for one minute, and wash with running water c) Decolorize with acetone/alcohol for three to four seconds, and wash with water d) Stain with safranin for 30 seconds, and wash with water Acid-fast stain a) Place Kinyoun carbolfuchsin stain on slide for five minutes, and wash with water b) Decolorize with acid alcohol for two minutes, and wash with water c) Counterstain with 0.5% methylene blue for two minutes, and wash with water India ink capsule stain a) Mix one drop of test fluid with one drop of India ink b) Cover with a coverslip c) Ring with petrolatum d) Look for a round organism against a dark background B Culture techniques: If culturing is unavailable from the hospital laboratory, culturing should be done as follows: Bacterial cultures a) Blood: The sample volume should equal 10% of the volume of the culture medium When the patient is treated with penicillin, consider using penicillinasecontaining broth for culture b) Ear and nose: chocolate blood agar, followed by 5% sheep blood agar, followed by MacConkey agar Place the swab in the transport medium Page 270 c) Throat: 5% sheep bland agar, followed by MacConkey agar Place the swab in the transport medium d) Skin: 5% sheep blood agar, followed by MacConkey agar, followed by thioglycollate, broth Place the swab in the transport medium e) Cavity fluids: Place in anaerobic culture containers Fungal cultures a) Use a scalpel to scrape the edges of the lesion in which fungus is suspected onto a glass slide b) Cover scraping with 10% to 20% KOH or NaOH, and apply a coverslip c) Warm for a few minutes d) Examine for spore fragments Viral cultures a) Pharyngeal, nasopharyngeal, and rectal cultures: Send in viral culture media b) Blood, bone marrow, CSF, and urine: Send in sterile containers c) Specimens should be cultured and sent within one hour after collection VI Liver Functions and Gastroenterology A Stool examination Blood: occult blood guaiac method a) Purpose: to screen for the presence of blood in the stool b) Reagents: glacial acetic acid, guaiac, hydrogen peroxide c) Method: Place a small amount of stool on the filter paper Serially apply two drops of each reagent in the following order: acetic acid, guaiac, and hydrogen peroxide Page 271 d) Interpretation: A positive test result will be a purple or dark blue color on the filter paper A negative test result is a green color on the filter paper Parasites a) Direct smear: Add a small amount of fecal material to a drop of saline mix, remove feces with an applicator stick, and cover Examine the specimen under low power to locate the parasites and high power to identify the parasites b) Preservatives: Specimens should be delivered to the laboratory immediately, Place in formalin if a delay in specimen delivery is anticipated B Diarrhea Definition: watery, frequent loose stool caused by a shift in the intestinal water and electrolyte transport due to an increased osmolar load or active secretion of water into the intestinal lumen Etiology of acute diarrhea (self-limiting, < 14 days) a) Infectious b) Preparative regimen: total body irradiation (TBI), ifosfamide, and carboplatin c) Drugs: antacids, antimicrobial agents, chemotherapy conditioning regimen, cardiac medications, magnesium replacement secondary to cyclosporin A Etiology of chronic diarrhea (> 14 days) a) Infectious: fungal (e.g., Candida), parasitic (e.g., Giardia), viral (e.g., cytomegalovirus) b) Inflammatory (e.g., ulcerative enterocolitis) c) GVHD of the gut d) Pseudomembranous colitis: secondary to antibiotic therapy caused by Clostridium difficile e) Secretory diarrhea: caused by an abnormal secretion of water and electrolytes into the intestinal lumen It persists despite fasting Page 272 f) Osmotic diarrhea: caused by the accumulation of poorly absorbed solutes in the intestine It usually stops with fasting Stool evaluation a) Fecal leukocytes: The presence of white blood cells is indicative of bacterial infection b) Occult blood (Hemoccult): Blood present in the stool may indicate bacterial infection or inflammation of the bowel c) Sudan III: Screen for fecal fat malabsorption d) Stool electrolytes: Secretory diarrhea tends to have an elevated stool sodium and a lower osmotic gap (< 100 mOsm/L) In malabsorption or viral illness, the stool tends to have a decreased sodium and increased osmotic gap (> 100 mOsm/L) e) Endoscopy evaluation with biopsy: Platelet count should be in the 50,000/L range Coagulation parameters should be within the normal range before a biopsy is performed Biopsies should be taken from the normal mucosa and the edges of the ulcerated mucosa Endoscopy intubation should be done with caution to prevent laryngeal bleeding C Constipation Definition: a decrease in the frequency of the stool, usually associated with painful or difficult passage of hard stool Etiology a) Functional: idiopathic b) Electrolyte imbalance: hypokalemia, hypocalcemia c) Drugs: antacids, anticonvulsants, antihypertensives, diuretics, opiates, phenothiazines Diagnostic studies a) Abdominal plain films to determine bowel obstruction Page 273 b) Barium enema/large intestine study: The test provides both x-ray and fluoroscopic techniques to demonstrate the anatomy of the large intestine Indications include to rule out obstruction, masses, and inflammatory changes Normal outcome shows normal position, contour, filling, and patency of the large bowel The procedure is as follows: Contrast agent (barium) is given in the form of an enema via the rectum Under fluoroscopy, the colon is completely filled to the ileocecal junction Contrast is maintained in the colon for several minutes while the x-rays are taken A postevacuation film is taken to ensure that all the barium is expelled The importance of forcing fluids after the procedure is stressed D Hemorrhage Definition: Minor gastrointestinal bleeding presenting as small hematemesis or bleeding Resolution usually occurs with correction of thrombocytopenia and correction of abnormal clotting Etiology a) Acute GVHD b) Duodenal ulcer c) Small bowel ulcer d) Gastric erosion Diagnostic study: upper endoscopy evaluation with biopsy a) Platelet count should be in the 50,000/L range b) Coagulation parameters should be within the normal range before a biopsy is performed c) Biopsies should be taken from the normal mucosa and the edges of the ulcerated mucosa d) Endoscopy intubation should be done with caution to prevent laryngeal bleeding Page 274 E Abdominal pain Etiology a) Duodenal ulcer b) Gallbladder disease c) GVHD d) Hemorrhagic cystitis e) Liver disease, veno-occlusive disease, viral hepatitis f) Pancreatitis Diagnostic studies a) Abdominal x-rays to determine bowel obstruction Films should be performed erect and supine b) Upper and/or lower endoscopy with biopsy: Platelet count should be in the 50,000/L range Coagulation parameters should be within the normal range before a biopsy is performed Biopsies should be taken from the normal mucosa and edges of the ulcerated mucosa Endoscopy intubation should be done with caution in the transplant patient to prevent laryngeal or rectal bleeding Symptoms of bowel perforation are abdominal distention, bleeding, fever, and pain c) Abdominal ultrasound: noninvasive procedure that produces sound waves from a handheld transducer Food restriction usually applies six to 12 hours prior to the examination Water is normally permitted The patient will be required to change position during the scanning procedure Breathing may need to be controlled during the imaging Examination time is usually 30 to 60 minutes VII Cytogenetics A Definition: Cytogenetics is the study of the origin, structure, and function of chromosomes It has the ability to identify certain genes that are associated with chromosomal abnormalities There are normally Page 275 23 pairs of chromosomes A chromosome is divided into three parts: a short arm called p, a long arm called q, and a centromere B Karyotype analysis: When chromosomes are stained, regions and bands are named from the centromere toward the telomere (the region at the end of each chromosomal arm) Chromosomal abnormalities are then identified according to the banding pattern Commonly identified chromosomal alterations are referred to as translocations, duplications, deletions, or inversions There are genes that are located close to the chromosomal rearrangement that cause the aberrant expression of the genes that control cell growth If there are changes in the leukocyte, they will result in unregulated leukocyte proliferation, and subsequently leukemia will develop C Application Abnormalities of the patient's karyotype classify disease and predict prognosis Cytogenetic markers not always predict remission; however, they are often indicative of remission duration Cytogenetic abnormalities can be classified as primary and secondary Primary abnormalities influence the patient's treatment and prognosis Secondary abnormalities, when identified, are indicative of a poor prognosis The presence of additions or deletions on chromosomes has a more favorable prognosis D Cytogenetic specimen sampling Cytogenetic specimens are usually obtained from bone marrow aspirate specimens Page 276 In the event that bone marrow aspirate is unavailable, cytogenetics can be obtained from peripheral blood VIII Endocrinology A Gonadal dysfunction Definition: damage that occurs to the germ cells resulting in substantial alteration of gonadotropin-releasing hormone levels Etiology a) TBI b) Chemotherapy conditioning regimen Diagnostic studies a) Measure pituitary luteinizing hormone (LH) and follicle-stimulating hormone (FSH) b) Males: elevation of FSH Testosterone ad LH are normal c) Females: elevation of FSH and LH Estrogen is usually low, d) Prepubescent girls: Delayed puberty will occur in 50% of the cases The delay is related to the age at the time treatment occurs e) Postpubertal females: anovulation with low estrogen levels and elevated FSH and LH levels f) Prepubescent boys: Delayed puberty occurs in 70% to 90% of the cases g) Spermatogenesis may be impaired B Growth hormone (GH) Definition: Impaired growth velocity and GH secretion may occur after high-dose chemotherapy and TBI This is caused by the decreased production of GH and growth factors like IGF-I, an insulin-like growth factor Etiology a) Chemotherapy b) TBI c) GVHD P Drug Supplied as Dose and
