In middleaged men with low testosterone levels, physiologic testosterone replacement has been shown to improve insulin sensitivity and reduce visceral obesity. The A1C 308 reductions with exenatide are modest compared to those with some oral agents. This process by which extrahepatic lactate is taken back to the liver, converted to glucose by gluconeogenesis, and returned to extrahepatic tissues is called the Cori cycle. In recent years, osteitis fibrosa cystica has been very rare in primary hyperparathyroidism, probably due to the earlier detection of the disease. The poison control center was contacted, but no treatment was recommended because it was confused with an acetone-based nail polish remover. This functional unit of each haversian canal with its surrounding lamellae of bone containing canaliculi radiating to it from the osteocytes trapped in the lacunae is known as an osteon or a haversian canal system. Bile is a controlled mixture of cholesterol, bile acids, and phospholipids (with small amounts of bile pigments), and if cholesterol levels are elevated or bile acids/salts lowered, the ratio of the three major components changes leaving cholesterol less protected against the aqueous environment and more likely to precipitate. Eye movements are composed of saccades (extremely rapid ballistic movements) that have an exploratory function and slower smooth pursuit movements that keep a target on the fovea and are subject to continuous modification. The glucose kinetic patterns resemble those of hyperinsulinism, but insulin secretion is suppressed appropriately during hypoglycemia. The most commonly used androgenic steroids include testosterone esters, nandrolone, stanozolol, methandienone, and methenolol. Estrogen loss probably causes bone loss by activation of bone remodeling sites and exaggeration of the imbalance between bone formation and resorption. Research concerning cola intake is controversial but suggests a possible link to reduced bone mass through factors that are independent of caffeine. Some of the smaller cysts are lined by large polygonal cells with abundant eosinophilic cytoplasm and small, round dark nuclei. Effect of marathon running on hematologic and biochemical laboratory parameters, including cardiac markers. This process requires integrating information regarding the plasma glucose, diabetes treatment regimen, and clinical status of the patient. The differential diagnosis is based on the results of initial tests including a pregnancy test, gonadotropins, and assessment of hyperandrogenism. An additional 18 million individuals are at risk for development of osteoporosis as measured by low bone density (osteopenia). Sometimes they may present as solid masses that are distinct or, rarely, infiltrative. The prostaglandins are hormone-like molecules that regulate cellular events near the area in which they are synthesized. Indirect evidence suggests that stress is an important environmental factor, presumably operating through neuroendocrine effects on the immune system. In adrenal insufficiency secondary to pituitary tumors or idiopathic panhypopituitarism, other pituitary hormone deficiencies are present. The only histologic means to differentiate between these two neoplasms is the presence of cells invading through the capsule surrounding the tumor or into blood vessels. She also has noticed that he appears very active and restless frequently getting into trouble in school. Initial investigations are Infertility 14% of reproductive aged women 5 million couples in the U. The expanded repeat appears to result in protein aggregation and the formation of intranuclear inclusions. This leads to an increase in heart rate, cardiac contractility, and venoconstriction that will serve to elevate mean arterial pressure. Syndromic associations and intrauterine growth retardation also occur relatively frequently in association with impaired testicular function or target-tissue responsiveness, but the underlying etiology of many of these conditions is unknown. One striking exception to the rule against parathyroid surgery in this syndrome is the occurrence, usually in consanguineous marriages (due to the rarity of the gene mutation), of a homozygous or compound heterozygote state, resulting in complete loss of the calcium sensor function. The classification and pathogenesis of acute and chronic gastritis are discussed below.

A 65-year-old man with a central left upper lobe lung mass presents with renal stones and generalized bone pain. Although found within the cytosol of virtually every cell, glycogen is primarily concentrated in muscle (cardiac and skeletal) and liver. Acromegaly Diabetes insipidus Hyperprolactinemia Kallmann syndrome Sheehan syndrome [20. Steroidogenesis in the ovary requires the development of follicles containing granulosa cells and theca cells surrounding the oocytes (Chap. He has noted some fatigue, malaise, and a 4-lb weight loss over the last 2 months. He continues to have poor libido and rarely desires sexual intercourse, even though he has been in a monogamous relationship for the past 8 months. Because normal thyroid function is suppressed, 131I is concentrated in the hyperfunctioning nodule with minimal uptake and damage to normal thyroid tissue. Prostanoid signaling molecules usually exit the cell that produces them to act on G-protein coupled receptors on the surface of the same cell or cells nearby (termed autocrine or paracrine actions). The microscopic examination of the bone marrow usually shows an increased number of plasma cells. However, if symptoms persist or a residual abnormality remains, then testicular ultrasound examination is indicated. In sitosterolemia, the intestinal absorption of plant sterols is increased and biliary excretion of the sterols is reduced, resulting in increased plasma and tissue levels of sitosterol and other plant sterols. Calcitonin this is a 32-amino acid hormone produced by the parafollicular C cells in the thyroid. Among the skin problems associated with obesity is acanthosis nigricans, manifested by darkening and thickening of the skin folds on the neck, elbows, and dorsal interphalangeal spaces. Basal cell carcinomas are the most common skin cancers, appearing on sun-exposed areas in older people. Because many patients are reluctant to initiate discussion of their sex lives, the physician should address this topic directly to elicit a history of sexual dysfunction. Though these mutations induce thyroid cell growth, this type of nodule is almost always benign. This tumor is characterized by an 11;22 chromosomal translocation identical to that found in primitive neuroectodermal tumors. The cells are of diverse lineages, such as Schwann cells, perineural cells, and fibroblasts. Coronary heart disease, cardiomyopathy with arrhythmias, left ventricular hypertrophy, decreased diastolic function, and hypertension occur in about 30% of patients. The goiter is hard, nontender, often asymmetric, and fixed, leading to suspicion of a malignancy. The third subtype, which may be referred to as iatrogenic polydipsia, results from recommendations to increase fluid intake for its presumed health benefits. In addition, there are also a few thalassemia mutations that segregate independently of the -globin gene, such as those involving the trans-acting regulatory factors that affect the expression of the -globin gene. Hearing also begins with sensory transduction in hair cells, which in this case are located within the scala media of the cochlea, in the organ of Corti. Up to 15 percent of cases of small cell carcinoma include paraneoplastic syndromes. Nevertheless, normal cells that also are rapidly dividing, such as the gastrointestinal mucosa, the oral mucosa, and the bone marrow cells, may be affected. Serum calcium and phosphorus concentrations and liver function test results are normal. Corticosteroids, such as highdose prednisolone, have been used commonly to treat the acute symptoms and induce remissions. Definitions Melanocytic nevi: Generally considered a benign neoplastic proliferation of melanocytes that vary considerably in clinical and histologic appearance.

Lack of intrinsic factor results in deceased or absent vitamin B12 absorption (pernicious anemia). Patients with uncomplicated stage I endometrial carcinoma are effectively managed with total abdominal hysterectomy and bilateral salpingo-oophorectomy. The effects of estrogen are seen in women with natural or surgical menopause and in late postmenopausal women with or without established osteoporosis. Hemiparesthesia: Numbness or impaired sensation experienced on one side of the body. Androgen supplementation in the setting of normal testosterone is rarely efficacious and is discouraged. Histologically, it is noted to be hypercellular and to have disorganized hyaline cartilage without significant atypia. Cells are considerably more permeable to the nonionized form of the drug, which explains increased antimicrobial activity observed at alkaline pH. Adenocarcinoma is the most common form of cancer, accounting for over 75 percent of all pancreatic cancers. It is characterized by excess water retention that produces oliguria and decreasing serum osmolality, increasing urine osmolality, and a decreasing serum sodium concentration (hyponatremia). Chronic elevations in blood glucose levels are also detrimental, being associated with oxidative stress and glycation of cellular proteins. This mass is resected surgically, and the pathologist diagnoses the lesion as a moderately differentiated squamous cell carcinoma. The inflammation may be predominantly acute, with neutrophilic infiltration, or chronic, with a predominance of lymphocytes and plasma cells. Congenital heart defects can be detected in stillbirths up to 10 times more frequently than in live births. It is likely that cellular dedifferentiation underlies most cases of ectopic hormone production. Section of one optic tract produces homonymous hemianopia, with loss of vision from the temporal half of one retina and the nasal half of the other. However, high-output heart failure is relatively rare and usually develops in patients with concomitant cardiac pathology. Schematic diagram showing the source and utilization of amino acids in metabolic processes. The physiologic functions of hormones can be divided into three general areas: (1) growth and differentiation, (2) maintenance of homeostasis, and (3) reproduction. Importance of thiamine: An important water-soluble vitamin used as a cofactor in enzymatic reactions involving the transfer of an aldehyde group. Neurofibrillary tangles are composed predominantly of paired helical filaments with some straight filaments that appear to have a comparable composition. Mesenteric adenitis may mimic appendicitis closely but is associated with a generalized viral illness and causes less severe pain. Dietary factors that play a role in the development of colon cancer: Diets rich in fat and red meat and low in fiber may contribute to the development of colon cancer. She reports that her menses had been regular with 28-day cycles since her early twenties. There are at least 200 b-thalassemia alleles that have been characterized to date. Most side effects of resins are limited to the gastrointestinal tract and include bloating and constipation. Concomitant selenium deficiency may also contribute to the neurologic manifestations of cretinism. Other medications such as nonsteroidal anti-inflammatory drugs and calcium channel blockers may cause peripheral edema, but they do not increase body fat. It is also possible that the liver is less capable of ketone body synthesis or that the insulin/glucagon ratio does not favor ketogenesis. Treatment depends on the exact etiology, although the common therapy includes avoidance of liver toxins, salt restriction, and possibly procedures to reduce the portal pressure.

Histologic sections show infiltrating groups of atypical squamous cells with abundant pink cytoplasm that form intercellular bridges and produce keratin ("keratin pearls"). Supplemental testosterone rarely enhances androgenization significantly, as endogenous testosterone is already increased. Pelvic pain is a common complaint that may relate to an abnormality of the reproductive organs but may also be of gastrointestinal, urinary tract, or musculoskeletal origin. It is important to note that in mitral stenosis the left ventricle is not affected. The presence of all three of these symptoms, in association with hypertension, makes pheochromocytoma a likely diagnosis. Tuberculosis usually is spread, with rare exceptions, by person-to-person droplet spread. Minimal lesion responds well to steroids and does not progress to chronic renal failure. Subnormal cortisol production during acute severe illness has been termed "functional" or "relative" adrenal insufficiency. The name pheochromocytoma reflects the black-colored staining caused by chromaffin oxidation of catecholamines. The development of a necrotic tumor involving a peripheral nerve in an area that was irradiated previously is characteristic of a malignant peripheral nerve sheath tumor. Similarly, pituitary imaging detects small, clinically inapparent pituitary lesions in at least 10% of individuals. Dietary history and a history of ingestion of vitamins or drugs are often helpful in diagnosing some of the less frequent causes. Starch, the plant storage polysaccharide, which is also a polymer of glucose, differs in its structure in that the glucose monomer units are joined by (14) glycosidic bonds. In some areas of bone, fibroblast-like cells develop features of osteoblasts in that they produce extracellular matrix that organizes into woven bone. Virilization refers to a condition in which androgen levels are sufficiently high to cause additional signs and symptoms such as deepening of the voice, breast atrophy, increased muscle bulk, clitoromegaly, and increased libido; virilization is an ominous sign that suggests the possibility of an ovarian or adrenal neoplasm. Adequate adrenal and thyroid hormone replacement should be ensured before testing. Hepatic porphyrias present with primarily neurovisceral symptoms such as: abdominal pain, nausea and vomiting, tachycardia and hypertension, peripheral neuropathy, and mental symptoms (hallucinations, anxiety, seizures). Intravaginal administration of bromocriptine is often efficacious in patients with intractable gastrointestinal side effects. It is divided into early and late latent syphilis, with early latent syphilis defined as 1 year after infection and late latent syphilis as infection longer than 1 year. Symptoms of diabetic cystopathy begin with an inability to sense a full bladder and a failure to void completely. Known complications of diverticulitis include bleeding, abscess formation, peritonitis, and fistula formation. Cortisol has numerous effects on the body, and in excess, can cause hypertension, lipolysis, "buffalo hump," "moon faces," easy bruising of the skin, and truncal obesity. Characteristic body habitus includes thin limbs with little muscle mass yet prominent and palpable bones and, when the skull is involved, large head with prominent forehead and proptosis. Hearing loss usually is subdivided into disorders of conduction (auricle, external auditory canal, and middle ear) and disorders relating to sensorineural conditions (inner ear or eighth cranial nerve). The ultrasound shows a complex (both cystic and solid) ovarian mass, which also is not consistent with an abscess or a physiologic ovarian or paraovarian cyst. One hazard of abruptly lowering the blood pressure is causing hypotension and subsequent ischemia to the brain or heart. The latest, still experimental, strategy in the treatment of Crohn disease involves the role of cytokines. Acetaminophen glucuronide Acetaminophen sulfate N-Acetyl benzoquinoneimine Acetaminophen glutathionate N-Acetyl-p-aminophenol [40.

Precursor lesions include squamous cell carcinoma in situ (which has not penetrated through the basement membrane) and actinic keratosis, which is also called a cutaneous horn, with marked hyperkeratosis and parakeratosis. The mechanisms by which the digestive enzymes become activated within the acinar cell are unclear. The pituitary has two lobes: the anterior lobe, which is derived from the Rathke pouch, and the posterior lobe. Headache, increased intracranial pressure, hypertension, atrial fibrillation, and tinnitus occur rarely. Consequently, the proportion of free cholesterol in circulating lipoproteins is greatly increased (from ~25% to over 70% of total plasma cholesterol) in this disorder. Hypogonadal men with prepubertal onset of androgen deficiency who begin testosterone therapy in their late 20s or 30s may find it difficult to adjust to their newly found sexuality and may benefit from counseling. The soluble fibers include pectins, gums, some hemicelluloses, and storage polysaccharides (starch and glycogen). Acid maltase Arylsulfatase A Glucocerebrosidase Homogentisate oxidase Phosphorylase [46. Many cases are associated with the presence in the serum of IgM anti-I cold agglutinins. The acceptor -keto acid is most often -ketoglutarate, therefore resulting in glutamate generation. The sequence of steps and the enzymes involved in the synthesis of steroid hormones are similar in the ovary, adrenal, and testes. The changes in body configuration and back pain can lead to marked loss of self-image and a secondary depression. Therapy of orthostatic hypotension secondary to autonomic neuropathy is also challenging. After reviewing all the laboratory results and her clinical picture, the patient was diagnosed with acute fatty liver of pregnancy. Pheochromocytomas occur in only about 1% of these patients and are located predominantly in the adrenals. Additional studies that should be performed: Bone marrow examination with flow cytometry and cytogenetics for the aspirate obtained from the bone marrow. The centriacinar variety is the most common, affecting the central or proximal aspects of the acini; the distal alveoli usually are not involved. Multiple myeloma is the most common primary malignancy arising in the bone of adults. These include flatus with discharge, fecal urgency, fatty/oily stool, and increased defecation. Patients may also have other autoimmune disorders, such as Hashimoto thyroiditis or Addison disease. Otherwise, our attempts are only empiric, in other words, only by trial and error and observation of association. Chylomicrons appear in the blood stream shortly after consumption of a meal containing fat. They shift to higher-than-normal glucose levels in people with poorly controlled diabetes who can experience symptoms of hypoglycemia when their glucose levels decline into the normal range. Once the body has received an environmental stress signal, it is detected by neurons in the cerebral cortex and transmitted to the hypothalamus. There is usually a marked increase in dense, fibrous tissue stroma, giving the tumor a hard consistency. Malignancies Resulting in Hypercalcemia Hypercalcemia usually is due to bony metastases in certain tumors. Thiazolidinediones promote a redistribution of fat from central to peripheral locations. Each of these formulations is administered daily for 3 weeks followed by a week of no medication during which menstrual bleeding generally occurs. Microscopic examination of a smear made from one these vesicles reveals scattered multinucleated giant cells with ground-glass nuclei.
Effective 500mg ponstel
The cavitations and areas of caseation are repaired by fibrous deposits, leaving open pockets or thick scars. As a result, free copper is deposited in various sites, including liver basal ganglia and cornea (with resultant Kayser-Fleischer rings), resulting in damage to those organs. In some tissues receptor binding is also coupled to the phosphoinositide signaling system to activate protein kinase C. Causes of myelophthisic anemia include metastases to the bone marrow, granulomas, and fibrosis (myelofibrosis). Inhibition of this step in cortisol biosynthesis relieves feedback inhibition of its biosynthetic enzymes, leading to accumulation of cortisol precursors, particularly 11-deoxycortisol. Insulin glargine is a long-acting biosynthetic human insulin that differs from normal insulin in that asparagine is replaced by glycine at amino acid 21, and two arginine residues are added to the C-terminus of the B chain. The acute leukemias are characterized by replacement of the marrow with very immature cells (blasts). Affected individuals have hundreds to thousands of polyps, typically presenting in the left colon. The parathyroid cell monitors calcium ion levels by means of a calcium-sensing receptor in the plasma membrane. If the primary tumor shows no evidence for lymphatic or vascular invasion and is limited to the testis (T1), then either option is reasonable. Bronchial Carcinoids the frequency of bronchial carcinoids is not related to smoking. It is generally assumed that this low T3 state is adaptive, as it can be induced in normal individuals by fasting. Extraglandular aromatase activity can also be increased in tumors of the liver or adrenal gland or rarely as an inherited disorder. Role of Genes versus Environment Obesity is commonly seen in families, and the heritability of body weight is similar to that for height. Streptomycin, a basic trisaccharide, causes misreading of the genetic code in bacteria at relatively low concentrations but can inhibit initiation at higher concentrations. If it is prolonged, copious sweating leads to volume depletion and tissue hypoperfusion. Inhibins function as potent antagonists of activins through sequestration of the activin receptors. Scleroderma or systemic sclerosis is characterized by excessive fibrosis throughout the body. By exciting interneurons that inhibit the same or homonymous (synergistic) alpha motor neurons, the Ib afferents trigger the reverse (or inverse) myotatic reflex, which protects the muscle from excessive contraction. A biopsy from her nasopharynx reveals a necrotizing vasculitis with chronic inflammatory cells and giant cells surrounding localized necrotic areas. A chest x-ray reveals consolidation of the right lower lobe along with air bronchograms, and a Gram stain of her sputum shows a predominance of gram-positive lancet-shaped cocci in pairs and chains. The beneficial effect of estrogen is greatest among those who start replacement early and continue the treatment; the benefit declines after discontinuation such that there is no residual protective effect against fracture by 10 years after discontinuation. As a consequence, affected individuals have low blood pressure, low serum potassium, low serum magnesium, and high serum bicarbonate. Because of the additive cardiovascular risk of hyperglycemia and hyperlipidemia, lipid abnormalities should be assessed aggressively and treated as part of comprehensive diabetes care. Administration of uncooked cornstarch at bedtime or even an overnight intragastric infusion of glucose may be necessary in some patients. Thiosulfate is used to displace cyanide from cyanomethemoglobin to form thiocyanate, which can be excreted, a happy ending for cyanide poisoning. Combination estrogen-progestin therapy, in the form of an oral contraceptive, is usually the first-line endocrine treatment for hirsutism and acne, after cosmetic and dermatologic management. This is made possible by a distribution of amino acid side chains in which hydrophobic residues are sequestered in the interior core of the folded globin subunits, while hydrophilic residues dominate the water-exposed surface of the globin fold.

Definitive diagnosis is based on nuclear features such as "Orphan Annie" or "ground glass" nuclei. Cardiovascular Risk Assessment the longterm effects of testosterone supplementation on cardiovascular risk are unknown. This, combined with the atypical chest x-ray findings, may delay the diagnosis and treatment of the disease, with devastating results. Some interventions have targeted the immune system directly (immunosuppression, selective T cell subset deletion, induction of immunologic tolerance to islet proteins), whereas others have prevented islet cell death by blocking cytotoxic cytokines or increasing islet resistance to the destructive process. Couples may need to be reminded that clitoral stimulation rather than coital intromission may be more beneficial. Liposomes can transfect a variety of cell types, are biodegradable and hypoimmunogenic, and can be manufactured to a drug standard. Apart from their biologic importance, amino acids are classified as essential or nonessential based on their ability to be synthesized in the body. A chest radiograph shows bilateral hilar lymphadenopathy but no lung or mediastinal masses. Arrows indicate that changes in glucose tolerance may be bi-directional in some types of diabetes. For each tablet, etidronate strength is 400 mg; tiludronate is 200 mg; alendronate is 40 mg; and risedronate is 30 mg. The speculum examination shows a 4-cm irregular fungating mass arising from the cervix. Controlled oxygen administration with nasal oxygen at low flows or oxygen with Venturi masks will correct hypoxemia without causing severe hypercapnia. In addition, vitamin D and phosphate treatments or calcium administration in the presence of mild hyperphosphatemia, such as during hemodialysis, may induce ectopic calcification. The infertility rate has remained relatively stable over the past 30 years, although the proportion of couples without children has risen, reflecting a trend to delay childbearing. Careful evaluation of patients over the subsequent 12 years provided reassurance that in some patients medical monitoring rather than surgery was still prudent yet promoted new questions about the natural history of the disease with or without surgery. Examples of operative interventions used for surgical manipulation of the gastrointestinal tract. Methylenetetrahydrofolate in turn is derived from tetrahydrofolate, which is generated from methyltetrahydrofolate. Myxomatous degeneration of the mitral valve or mitral valve prolapse is estimated to occur in up to 3 percent of adults in the United States, especially women. This individual has a moderate to severe form of the disease; more advanced disease may include immobility, being mute, and being severely disabled. The low body weight and fat mass observed in the patient are consistent with a metabolically "fasted" state. Their first child was normal at birth, a slightly larger than normal head circumference, an abnormal "eye finding," and a severe progressive neurologic disease with decreased motor skills and eventually death. Activation of the ovum also blocks penetration of the zona and membrane fusion by additional sperm to prevent polyspermy. Theories regarding pathogenesis have referred to genetics, infection, autoimmune or allergic processes, thromboembolic disorders, and dietary disorders. Although gonadotropin deficiency and reproductive dysfunction are well documented in these conditions in women, men exhibit similar but less-pronounced responses. These hormonal changes decrease libido and reduce fertility in patients with hyperprolactinemia. Immediate treatment of this patient should include ongoing glucose administration while attempting to determine the cause. Hemicelluloses have a random, amorphous structure that is suitable for their location in the plant cell wall matrix.
Ponstel 250mg lowest price
Histologic sections of the bronchial-derived type of adenocarcinoma reveal prominent gland formation, the lumen of which may contain abundant mucin. Reiter syndrome: An arthritic disorder of adult males that is associated with conjunctivitis and urethritis. Repeated injections (often more than five sessions) are required to reduce nodule size. These individuals exhibit symptoms of hypothyroidism as well as a high incidence of attention-deficit disorder. Historically, nutrition education imposed restrictive, complicated regimens on the patient. Quaternary structure is the manner in which subunits of a multi-subunit protein are arranged with respect to one another. Several recent observational studies suggest that the statin drugs, currently used to treat hypercholesterolemia, may be associated with increased bone mass and reduced fractures, but conclusions from clinical trials are mixed. The potencies of various bisphosphonates are expressed relative to that of etidronate, the first clinically useful agent in this class. The most active single agents with consistent response rates of 20% include cisplatin, carboplatin, doxorubicin, epirubicin, and paclitaxel. Raising the serum inorganic phosphate concentration above normal decreases serum calcium levels, sometimes strikingly. Laboratory testing plays an essential role in endocrinology by allowing quantitative assessment of hormone levels and dynamics. Plasma glucose <55 mg/dL, plasma insulin >18 pmol/L, and plasma C-peptide levels >0. Severe cases are inherited in an autosomal recessive manner, but the genetic patterns are less clear for the milder forms. The patient has mild cervical lymph node enlargement but otherwise has a normal examination. Blood work to be obtained includes a complete blood count and a chemistry panel to assess electrolytes and serum creatinine for kidney function. Sperm density can decrease temporarily after acute febrile illness in the absence of a change in testosterone production. Also, a chronic carrier state may be seen in which the virus continues to replicate but does not cause hepatic damage in the host. Affected patients are at a sixfold increased risk of severe iatrogenic hypoglycemia during aggressive glycemic therapy of their diabetes. On examination, the boy appears restless and his speech is significantly delayed and incomprehensible. Osteitis Fibrosis after Parathyroidectomy Severe hypocalcemia after parathyroid surgery is rare now that osteitis fibrosa cystica is an infrequent manifestation of hyperparathyroidism. Although a deficiency in a number of enzymes can result in exercise intolerance, the lack of an increase in serum lactate following ischemic exercise points to an inability to a defect in the breakdown of glycogen in the muscle. Vasopressin is synthesized in the hypothalamus and stored in the posterior pituitary. Prior androgen therapy does not affect subsequent response to gonadotropin therapy. The phosphate groups are located on the outside of the double helix with the base pairs forming the "stair steps" in the center of the spiral. This procedure may be curative in cases of low-volume metastatic disease, because most germ cell tumors progress in an orderly fashion from primary intratesticular to lymphatic before metastasis to solid organs. Body composition changes are common and include reduced lean body mass, increased fat mass with selective deposition of intraabdominal visceral fat, and increased waist-to-hip ratio. The inherited disorders are much more common among younger individuals presenting with pheochromocytoma.
