The medications described do not necessarily have speCific approval by the Food and Drug Administration for use in the diseases and dosages for which they are recommended. Because standards for usage change, it is advisable to keep abreast of revised recommendations, particu larly those concerning new drugs. Six years later, we are proud to report that the original books and the entire Blueprints brand of review materials have far exceeded our expectations. The student-to-student approach was highly acclaimed by our readers, so resident contributors have been recruited to ensure that the third edition of the series continues to provide the content and approach that made the original Blueprints a success. It was suggested that the review questions should reflect the current format of the Boards, so new board-format questions have been included in this edition with full explanations provided in the answers. Our readers asked for an enhanced art program, so a second color has been added to this edition to increase the usefulness of the fgures and tables. However you use Blueprints, we hope that you fnd the books in the series informative and useful. Please send any comments you may have about this book or any book in the Blueprints series to blue@bos. The Publisher Blackwell Publishing e are gratefl for the continued support that we have received for Blueprnts Medicine. We wish to thank all of the people at Blackwell Publishing who helped us with prepara tion of this work. We appreciate the input of the medical student and resident reviewers who worked hard to ensure that the Blueprints series continues to maintain a high standard of excellence. Finally we wish to thank our families for all of their support during this project. Inflammation of serous surfaces leads to pleuritic History pain, characterized by increased pain with inspiration or cough. This pain may also be aggravated by move the following diseases often present with the sharp ment or position. Pneumothorax has an acute monary etiologies, pericarditis, and muculoskeletal onset and is pleuritic and associated with dyspnea. Visceral pain, such as in myocardial this occurs mostly in young patients (spontaneous) ischemia and esophageal disease, ofen produces dull, or those with underlying lung disease (secondary to aching, tight, or sometimes burning pain that is blebs). Risk factors should the most important decision for the physician be taken into account (see Chapter 16). The pain in is to distinguish life-threatening causes, such as pericarditis is pleuritic and positional, typically myocardial ischemia, pulmonary embolus, and aortic relieved by sitting forward. The key carditis may radiate to the shoulder/trapezius (due to to identifing the etiology of the pain lies in the diaphragmatic/phrenic nerve irritation). In contrast, other diseases may produce a more visceral type of pain, aching and poorly localized.

Thus to prostate lump discount tamsulosin 0.4mg line meet an accretion rate of 100 mg/kg/day with an absorption rate of 75% and an assumed retention rate of 75% (which may be on the high side) prostate cancer statistics 0.2 mg tamsulosin sale, oral intake of calcium for growing premature infants should be about 200 mg/kg/day prostate 79 grams discount tamsulosin 0.2 mg online. This large intake in infants with very low birth weight can be achieved only with special formulas for low-birth-weight infants or mineral fortifers for breast milkfed preterm infants. How can the calcium requirements for premature infants be met by hyperalimentation solutions This problem is much more diffcult to address, although intestinal absorption is not a factor. Clinical rickets develops in preterm infants with very low birth weight who are fed human milk not fortifed with minerals and vitamins. Typically, the disease presents after 8 weeks of life with severe hypophosphatemia, relative hypercalcemia, and hypercalciuria. Because human milk is low in both calcium and phosphorus, the very low phosphorus intake (about 50% of calcium intake) severely limits deposition of calcium in bone. Caution: Because treatment with phosphorus alone can result in severe hypocalcemia, supplements of both minerals are imperative. What is the differential diagnosis of the etiology of a hypocalcemic seizure in a 14-day-old term infant Seizures secondary to hypocalcemia are very unlikely in a previously healthy term infant at 2 weeks of age. The differential diagnosis includes late infantile tetany associated with high phosphate load. What is the appropriate therapy for a hypocalcemic seizure in a 14-day-old term infant Treatment of hypocalcemic seizures is the same for both premature and term infants. Infusion should occur slowly over the course of 10 minutes with heart rate monitoring. There are three fractions of calcium in serum: ionized calcium (50%), calcium bound to serum proteins (40%), and calcium complexed to serum anions (10%). Normal values (in milligrams per deciliter, expressed as mean standard deviation and range) depend on chronologic age and laboratory variation (to a lesser degree): n Cord: 10. Normal values (in milligrams per deciliter, expressed as mean standard deviation and range) depend on gestational age: n 2327 weeks: 10. Cord blood calcium, phosphate, magnesium, and alkaline phosphatase gestational age-specifc reference intervals for preterm infants. A 3-day-old infant born small for gestational age at term has a total serum calcium level of 13. Williams syndrome is the likely diagnosis in an infant with hypercalcemia and supravalvular stenosis who was born small for gestational age. Family history reveals that the father has also been evaluated for elevated calcium levels. What would you expect to fnd on measurement of the infants urinary calcium level The most likely diagnosis is an autosomal dominant mutation of the calcium-sensing receptor, or hypocalciuric hypercalcemia. In the heterozygous state this is generally thought to be a benign condition, and treatment is not indicated. Rare cases of homozygous mutations result in severe neonatal hyperpara thyroidism, which is a life-threatening disorder. A defect in the intestinal transport of tryptophan causes excretion of blue, water-insoluble tryptophan metabolites. How are millimoles (mmol) of magnesium converted to milliequivalents (mEq) and milligrams (mg) Magnesium is the second most abundant intracellular cation after potassium and helps to regulate cellular metabolism. As part of the magnesium-adenosine triphosphate complex, it is essential for all biosynthetic processes, including glycolysis, formation of cyclic adenosine monophosphate, and transmission of the genetic code. However, extracellular concentrations are critical for maintenance of electric potentials of nerve and muscle membranes and for the transmis sion of impulses across the neuromuscular junction. Magnesium and calcium may act synergistically or antagonistically in many of these processes.

The oligomeric and monomeric diets were formulated to prostate examination video tamsulosin 0.2 mg online require minimal digestion by the gastrointestinal tract man health org health id discount tamsulosin 0.4 mg visa, with little necessity for bile and pancreatic secretions prostate cancer 8 scale order tamsulosin 0.2mg with visa, and minimal work by the enterocyte in terms of brush-border enzyme activity or re-esterification. Hence, these diets have been commercially promoted as ideal for patients with decreased bile output (cholestasis), pancreatic insufficiency and short bowel. However, there is little evidence First Principles of Gastroenterology and Hepatology A. Finally, the high cost of these diets (often five to 10 times that of polymeric diets) rarely justifies their use. Most of these formulas provide enough protein, calories, water, electrolytes, minerals, vitamins and trace elements in 2 L/day or less for most nonstressed patients. As with polymeric formulas, specialized amino acid solutions have been made for use in special circumstances for example, liver disease, renal disease and stress, such as trauma and sepsis. For liver disease, these solutions are composed mostly or exclusively of branched-chain amino acids, whereas for renal disease the solutions are predominantly essential amino acids. There has been considerable interest in immunonutrition which refers to formulas which have been enriched with nutrients purported to alter immunity. Such nutrients include amino acids such as arginine and glutamine, fish oil (omega-3 fatty acids), antioxidants and nucleotides. Systematic reviews of immunonutrition have been reported in intensive care and surgical patients but the role of these specialized products remains controversial. In general, enteral feeding is well tolerated, and provided the complications are known, preventive and/or corrective measures may be undertaken to minimize patient risk. Aspiration of the infused formula, with development of pneumonia, is a potentially lethal complication of tube feeding. Risk factors for aspiration include patients on a ventilator and those with gastroesophageal reflux, poor or absent gag reflex, and impaired mentation. To minimize aspiration, it is suggested that patients, when possible, be fed with the head of the bed elevated 2030. Gastric contents should initially be checked by aspirating the tube every four to six hours and if the residual volume is > 150 mL, the infusion should be temporarily stopped. Unfortunately, the small nasoenteric tubes in current use often collapse when aspirated, so small returns do not guarantee that the stomach is not becoming distended with fluid. Hence, examination for epigastric distention and succussion splash should be done. If there is any concern, an upright (if possible) plain film to assess gastric size may be useful. It has also been suggested that the feeding tube be placed into the small bowel well beyond the pylorus to minimize aspiration in those at risk, though studies have failed to confirm this. The following mechanical problems in patients with nasoenteric tubes include problems in the upper respiratory tract and esophagitis with development of esophageal ulceration, stenosis and even tracheoesophageal fistula. Upper respiratory problems include pharyngeal irritation, nasal erosions and necrosis, sinusitis and otitis media. These mechanical problems can be largely avoided by the use of soft, small-bore nasoenteric tubes. Gastrointestinal problems related to nasoenteric feeding are common, occurring in 2030% of patients. The most frequent complaints are nausea, vomiting, abdominal distention and altered bowel habit. Symptoms may be minimized by feeding at a slow rate with dilute solutions, but these symptoms may be just as common as with full-rate, full-strength solutions. If a lactose-containing solution is being used (generally First Principles of Gastroenterology and Hepatology A. Shaffer 665 not recommended for tube feeding), changing to a lactose-free solution is indicated. For constipation, fiber-containing solutions may be tried, although they are often unhelpful. Fiber, however, is a potential energy source for the colon, as previously discussed, and may therefore be important for maintenance of the colonic mucosa.

Examination of the pharynx may reveal pharyngitis androgen hormone vertigo purchase tamsulosin 0.2mg otc, and laryngoscopy may reveal a red mens health 032013 discount tamsulosin 0.4 mg visa, swollen larynx; thickened cords; and an abundance of mucous secretions prostate cancer metastasis sites buy tamsulosin 0.2 mg cheap. Do not try to visualize the airway, as it can precipitate an episode of extreme respiratory distress. Soft tissue radiographs are diagnostic; they show thumbprinting of the epiglottis. Potentially fatal as well, as acute swelling of the airway can lead to ob struction. Fever, restlessness, dehydration, agitation, tachycardia, and tachypnea may be evident as well. In addition to cessation of smoking and voice use, the vocal cords must be stripped in stages for complete resolution. De nitive treatment is by lifestyle modi cations (smoking, voice abuse), endoscopic removal of the lesion, and stripping of the cords if lesions are bilateral. Iatrogenic: Birth trauma, thoracic/cardiac or neck surgery (thyroidectomy with injury to the recurrent laryngeal nerve, cervical spine diskectomy/ fusion). Surgical options include vocal fold injection with alloderm, a gel or collagen-based substance (injection thyroplasty), or medialization of the cords by removing a portion of the thyroid cartilage and inserting a shim (Montogomery thyroplasty). In cases of severe airway problems, a tracheotomy may be the only way to improve airway function. Can also occur from trauma to the trachea and larynx, neoplastic dis ease, irradiation, severe infection, or congenital stenosis (hemangioma, subglottic webs and cysts). The exception to this rule is glottic carcinoma, which presents earlier and has a small likelihood of lymphatic metastasis (owing to the poor lymphatic drainage of the glottis). The presentation of laryngeal cancer is usually progressive hoarseness Tracheostomy vs. Options are available for voice reconstruction (a tracheoesophageal laryngeal cancer. The one-way valve) and return of swallowing that allow these patients to trachea is rerouted to have a good quality of life. Sympathetic bers come from the superior thoracic nerves and synapse with the superior cervical ganglion. Saliva is high in potassium, low in sodium; it contains substances that begin the breakdown of food, to maintain and protect the oral cavity environment, and immunoglobulin A (IgA). Gustatory sweating There is morphologic diversity: the tumor can be mucoid, chondroid, following parotid surgery, osseus, or myxoid. Symptoms: Range from asymptomatic swelling (75%) to pain and facial nerve paralysis. Arises from the terminal tubules and intercalated or strained duct cells in the gland. Malignant but slow growing; most patients are asymptomatic on presen tation even though a large percentage of those tumors are xed to adja cent structures. Anteriorly, there are two layers to this fasciathe prevertebral layer lies anterior to the cervical vertebrae from the skull to the coccyx; anterior to that is the alar layer, which extends from the base of skull to the mediastinum. Anterior to that is the visceral/buccopharyngeal fascial layer of the middle fascia. Above the hyoid bone: Parapharyngeal: Infectious spread from tonsils, pharynx, teeth, pa rotid gland, and extension from other spaces. Danger/alar space: Between alar layer and the prevertebral layer of deep cervical fascia. Lymph node areas are divided into different levels, which become rele vant when performing a neck dissection and staging nodal disease. A cyst can also de velop if part of a groove or pouch becomes separated from the surface and does not resorb and become prone to repeated infections; need to be excised completely. The cyst can be at any level along the route of the duct, and usually moves with swallowing and protruding the tongue because of its attach ment to the base of tongue. Usually presents with multiple, slow-growing, rubbery lymph nodes in the neck, which may be the only presenting symptom of the disease. A surgical dissection and re lymph nodes are not moval of the neck nodes and associated structures is necessary to pathologi cally identify and treat the disease.

What are the syndromes and malformations associated with congenital limb hemihypertrophy Most newborns with hypoplastic left heart syndrome have this defect as an isolated abnormality prostate cancer hip pain buy tamsulosin 0.2 mg line, but several syndromes with which this congenital heart malformation is a component have been identi fed: Down syndrome androgen hormone kit purchase 0.4 mg tamsulosin overnight delivery, Turner syndrome prostate levels normal numbers - 08 discount 0.2mg tamsulosin amex, SmithLemliOpitz syndrome, trisomy 13, trisomy 18, and Ivemark syndrome. Before extensive reconstructive surgery is attempted, it may be prudent to obtain a chromosome microarray analysis. Standard genetic care in pregnancy should include evaluating the family history; screening for hemoglobinopathies; offering carrier testing for cystic fbrosis; and evaluating for aneuploidy, including noninvasive testing such as nuchal translucency and serum screening or invasive testing such as cho rionic villus sampling or amniocentesis. Certain populations or individuals should be offered specifc genetic testing for monogenic disorders depending on their personal or family history or their ethnicity. When taking a family history, the clinician should gather information about the number and relation ships of family members with birth defects, growth problems, mental retardation, serious medical problems (especially those at a young age), auditory or visual impairment, ethnicity, and consanguinity. Prenatal genetic testing can be performed by chorionic villus sampling or amniocentesis. There is a chance that a genetic abnormality could be identifed by chorionic villus sampling that is confned to the placenta (confned placental mosaicism) that will have little bearing on the fetus if the placenta develops normally. Carrier screening for cystic fbrosis is currently offered to all couples contemplating pregnancy or currently pregnant, regardless of ethnicity. The sensitivity of carrier screening for diseases such as cystic fbrosis depends critically on the ethnicity of the patient. In the evaluation of a stillborn infant, how does the general appearance of the fetus suggest a likely etiology A fresh embryo or fetus implies a rapid expulsion after intrauterine or intrapartum death. A macerated fetus indicates prolonged reten tion and is more likely to be associated with structural malformations or chromosomal anomalies. Couples with recurrent pregnancy loss, defned as three or more losses, should be considered for the following evaluations: n Cytogenic analysis of both parents to rule out mosaicism or a balanced translocation n Hysterosalpingography to rule out malformations of the uterine cavity. Major malformations are unusual morphologic features that cause signifcant cosmetic, medical, or developmental consequences for the patient. Approximately 14% of newborns will have a minor malformation, whereas only about 2% to 3% will have a major malformation. In early pregnancy (before 4 months), the majority of amniotic fuid is produced by transudation through the placental membranes and fetal skin. Potter syndrome is associated with oliguria and low levels of amniotic fuid, which lead to compression of the face during development and dysmorphic facial features that can include hypertelorism. At term the fetus swallows approximately 500 mL of amniotic fuid per day and urinates an equivalent amount. Any malformation that leads to impaired urine production will cause oligohydramnios, including renal dysplasia, renal agenesis, and bladder outlet obstruction. When uteroplacental insuffciency occurs, the fetus is often faced with poor nutritive and volume support. The fetus becomes intravascularly depleted, leading to increased fuid conservation and decreased urine output, causing oligohydramnios. The etiology of polyhydramnios may be broken down into maternal causes (30%), fetal causes (30%), and idiopathic causes (40%). Maternal disorders, such as diabetes, erythroblastosis fetalis, and pre eclampsia, are often associated with excessive amniotic fuid. Potter syndrome has come to be synonymous with fetal malformations caused by extreme oligohy dramnios. A lack of amniotic fuid leads to fetal compression; a squashed, fat face; clubbing of the feet; pulmonary hypoplasia; and, commonly, breech presentation (Fig. Normal fetal lung devel opment depends on in utero breathing and production of fetal lung fuid. In the absence of amniotic fuid, pulmonary hypoplasia occurs and is the cause of death for most fetuses with Potter syndrome. Syndactyly and postaxial polydactyly can be observed with genetic conditions such as BardetBiedl syndrome. However, bladder outlet obstruction and prolonged premature rupture of the membranes may also cause this sequence.
