You are the primary pediatric resident on the hematology/oncology team and covering the service over the weekend heart attack women discount 160 mg diovan overnight delivery. A 6 year old was admitted on Thursday lennox pulse pressure test kit 40mg diovan mastercard, with a history of being tired heart attack fever buy cheap diovan 80 mg online, shortness of breath, pallor and weight loss. Following the family conference and consent process to begin the child on a lymphoma protocol, treatment was started by the weekend. The chemotherapy is being administered properly, with attention to tumor lysis precautions, including vigorous hydration. As you make your midnight rounds, you notice that the documentation of fluid input and output shows a large discrepancy. The amount of fluid administered (orally and intravenously) is almost twice the volume as the urine output. You suspect that the patient is experiencing complications from the chemotherapy and think you should do which of the following: a. Increase the hydration because the fluid balance is not equal, and the patient should be receiving more than twice maintenance fluid intake during induction chemotherapy. Perform a thorough physical exam, have the patient weighed, repeat the serum electrolytes immediately to determine if the patient is fluid overloaded. The patient is experiencing renal failure, and needs immediate consultation by a nephrologist to begin dialysis. You decide that the oral fluid intake has not been taken into consideration, which it should be, and estimate the amount the patient has been taking in orally based on what was served on his meal trays. By your calculations, the total fluid intake and output is equal, therefore no further action is needed. The parents of a 5 year old boy bring their son to see you because they are concerned that their son has leukemia. Your physical exam is unremarkable except for the bruises noted on the anterior legs and on the forearms. Reassure the parents that you do not suspect them, but you should alert them of your concerns and find out who could possibly be the perpetrator. The fact that the child is short of breath in the supine position could be related to a mediastinal mass, which can be identified on a chest x-ray. A mediastinal mass could be a potential emergency situation, therefore a chest x-ray should be considered shortly after the history and physical exam are completed. Live vaccines are contraindicated throughout the treatment course due to the immunocompromised status of the patient. Delays in growth and development may occur as a result of chemotherapy and/or radiation therapy. The chemotherapy may have induced tumor lysis causing hyperuricemia, which in turn may be affecting the kidneys. Solid Tumor Childhood Malignancies Christina Keolanani Kleinschmidt An 18 month old female presents to the office for her well-child examination. A third year medical student is allowed to take the history and perform the initial examination. On a routine ophthalmoscopy exam, the student notices that the child does not have a red reflex in the right eye. There is no history of weight loss, anorexia, crossed eyes, fever, or irritability. An ophthalmoscopy exam performed under general anesthesia reveals a tumor in the posterior pole of the right eye. Careful follow ups are scheduled to monitor for recurrences or development of secondary tumors. Retinoblastoma Retinoblastoma is a slow growing malignant tumor of the retina that may be confined to the eye for up to months or even years. The mean age of diagnosis in bilateral tumors is 12 months whereas unilateral tumors occur at a mean of 24 months of age (2).

Connective Tissue and Its Heritable Disorders: Molecular, Genetic, and Medical Aspects 2nd edition. Location of fracture (femur and radius vs tibia and radius), type of fracture (comminuted mid shaft vs epiphyseal and greenstick). Careful fracture history, identifying weak bones, and targeting physical therapy to strengthen those bones. Any of the following: pectus carinatum (or excavatum sufficiently severe to require surgery), reduced upper to lower segment ratio, positive wrist and thumb signs, scoliosis greater than 20 degrees of curvature, reduced extension of elbows, medial displacement of medial malleolus causing pes planus, protrusio acetabuli. Any three of the following: hyperextensible doughy skin, atrophic scars, joint hypermobility, connective tissue fragility, and bruising. Marfan syndrome, unlike homocystinuria, is not associated with mental retardation. On the phone is a lab technician from another state who reports that a newborn screen reveals a positive test for galactosemia in one of your patients. The child was discharged home from the hospital at just under 48 hours of age, he appeared well with only a 3% weight loss and mild facial jaundice upon follow-up at day 4 of life. His parents reported no breast feeding difficulties and, despite their concern for the number of hours their new baby slept, the new family appeared to be thriving. Genetic testing has received much attention in the press, with interest focusing on the ethics and repercussions of genetic information. Despite this attention, most people do not realize that for the past twenty years, almost all newborns in the United States have been screened for a number of genetic diseases. Almost all newborn screen tests are quantitative tests for the presence or absence of metabolic or endocrine molecules. When the concentration of the tested molecule is greater or less than a level determined by the reference lab, the test is reported as positive. In order to provide 100% sensitivity for disease, the level of positive detection must be adjusted to a point at which specificity may be quite poor. Of these, 54 infants were confirmed to have the disease (positive predictive value 0. Improvements in mass spectroscopy are greatly increasing the number of inborn errors of metabolism that can be efficiently screened in all newborn infants. A single gene must be discovered and sequenced, which when altered, produces a recognizable disease state. For every detectable alteration, a single unique test must be created and performed. On the other hand, some diseases such as Duchenne muscular dystrophy or osteogenesis imperfecta, may result from one of hundreds of different possible alleles. Cystic fibrosis represents a middle ground, in which hundreds of disease alleles exist, but only a handful produce the vast majority of illness in select populations. In European descendants, the delta F508 allele represents 70% of disease alleles in that gene pool and four additional alleles represent another 10-20%. As more disease alleles are discovered, more tests can be run to determine if each allele is present in a given patient. Each matching test involves a small unique section of single stranded nucleic acid which is glued to the wafer in a specific grid position. There are several other methods to detect genetic based illnesses, including the visual inspection of chromosomes, the augmented inspection of chromosomes using fluorescent antibodies, and multiple methods of detecting the presence, absence and relative quantity of proteins. In theory, the information to predict susceptibility to all genetically based disease is available in zygotes and ancient human remains. As science progresses and discovers how genetic information predicts disease states, the ethical debates over how best to use the information must also progress. Page 129 Since the discovery that genetic information can predict disease states, people have been afraid that this information might be used in a discriminatory manner.

Roseola infantum (exanthem subitum hypertension handout discount 40mg diovan with visa, sixth disease) is caused by human herpes virus 6 hypertension diet plan cheap diovan online. The prodrome consists of constant or intermittent high fever with malaise and irritability lasting 3 to heart attack 34 years old buy 40mg diovan with mastercard 5 days. Erythematous to pink macules and papules appear, often arranged in rosettes, mainly involving the trunk with extension to the neck and proximal extremities lasting for 1 to 2 days (2). Most infants are affected subclinically with two studies showing only 9-17% developing clinical roseola infantum (4). The course is generally benign, but febrile seizures, meningitis, and encephalitis are well-recognized complications. The period of infectivity extends from the beginning of the prodromal illness through the time that the uncrusted lesions are present (2). Transmission is via respiratory secretions and the fluid produced by skin lesions, either airborne or through direct contact. Transmission to susceptible individuals occurred at a rate of 80-90% for household members. The incubation period is 14 to 16 days and initial symptoms typically consist of fever, malaise, headache, anorexia, or abdominal pain (2). Temperature elevation is usually moderate but may be as high as 41 degrees C (106 degrees F) (5). They begin as intensely pruritic, erythematous macules which rapidly evolve into vesicles containing serous fluid. Over a 24 to 48 hour period, the Page 236 vesicles umbilicate, the fluid clouds, then transforms into crusts before finally resolving. Healed lesions may leave residual hypopigmentation lasting weeks, but scarring is uncommon. Ulcerative lesions of the oropharynx and vagina commonly develop concurrently with the exanthem. Acyclovir and varicella-zoster immune globulin have been effective in the prophylaxis and treatment of progressive disease, as described below. The course is generally benign, although in certain populations it may be associated with several complications. Progressive varicella is characterized by visceral organ involvement, coagulopathy, severe hemorrhage, and continued lesion development. Severe abdominal pain and the appearance of hemorrhagic vesicles in otherwise healthy adolescents, immunocompromised children, pregnant women, and the newborn may be a red flag for this serious complication (5). Delivery within one week before or after the onset of maternal varicella frequently results in the newborn developing varicella, which may be severe and requires the administration of varicella-zoster immune globulin and acyclovir. A characteristic zig-zag scarring, often in a dermatomal distribution, can sometimes be seen (5). The lifetime risk for those with a history of varicella is 10%, with 75% of cases occurring after 45 years of age (5). Other viruses which commonly cause exanthems include adenovirus (rash, conjunctivitis), echovirus ("Boston exanthem" similar to roseola), and Epstein-Barr virus (see chapter on Epstein-Bar virus). A common rash associated with amoxicillin use is probably related to a viral etiology. Commonly called an "amoxicillin rash", this is a non-allergic rash which occurs when amoxicillin is used in conjunction with some viruses (which are poorly defined). Later, when the viral infection is resolved, amoxicillin use does not result in a rash. This is similar to infectious mononucleosis which results in an impressive rash with amoxicillin/ampicillin use, but no recurrence of a rash with the same antibiotic use, once the viral infection has resolved. Most amoxicillin rashes are non-urticarial which is the best (though not perfect) clue that this is probably not due to an allergic mechanism. Name the type of exanthem depicted in the case described at the beginning of this chapter.
