Absorption of many molecules occurs by co- transport purchase 100mg zudena with mastercard erectile dysfunction devices, a variation of active transport in which absorption into the cell against the concentration gradient is linked to the secretion of a cellular ion such as sodium down its concentration gradient purchase zudena without a prescription erectile dysfunction doctor nyc. This process is important for the absorption of glucose and amino acids in the small intestine purchase 100 mg zudena free shipping erectile dysfunction diet. The small intestine contains a wide variety of transporters (amino acid transporters, oligopeptide transporters, glucose transporters, lactic acid transporters etc. On the basolateral membrane, the presence of amino acid and oligopeptide transporters has been demonstrated. Active transport mechanisms for di- and tri-peptides have also been demonstrated in the nasal and buccal epithelia. Facilitated diffusion involves carrier-mediated transport down a concentration gradient. The existence of the carrier molecules means that diffusion down the concentration gradient is much greater than would be expected on the basis of the physicochemical properties of the drug. A much larger number of substances are believed to be transported by facilitated diffusion than active transport, including vitamins such as thiamine, nicotinic acid, riboflavin and vitamin B6, various sugars and amino acids. Both processes exhibit classical saturation kinetics, since there are only a finite number of carrier molecules. Thus unlike passive absorption (paracellular or transcellular), where the rate of transport is directly proportional to the drug concentration (Figure 1. At higher concentrations, the carrier mechanism becomes saturated and the rate of absorption remains constant (Figure 1. If a drug is sufficiently similar to a substance naturally transported by a carrier-mediated system, the drug may also be transported by the same system. For example, the drugs levodopa, methyldopa and 15 penicillamine are all absorbed via various amino acid transporters. Serine and threonine derivatives of nitrogen mustard, which have been investigated for antitumor activity, are also absorbed by a carrier- mediated process. Digitalis and other cardioselective glycosides also demonstrate behavior not compatible with simple partition theory, which suggests the involvement of carrier-mediated transport. Considerable attention is being focused on the identification of the structural requirements necessary for the binding and transport via the di- and tri-peptide transporters present in the gastrointestinal tract, in order to exploit this route for the oral delivery of peptides. Critical structural features that have been found to influence transport include stereoisomerism, side-chain length and net charge. Several drugs including a pGlu-L-dopa prodrug, as well as angiotensin-converting enzyme inhibitors and various thrombin inhibitors, have all demonstrated success in targeting endogenous transporters and enhancing transport across the intestinal mucosa. Endocytic processes All the above transport mechanisms are only applicable to the absorption of small molecules, less than approximately 500 Da. There is evidence that larger molecules can be absorbed with low efficiency due to endocytosis. Endocytosis is defined as the internalization of plasma membrane with concomitant engulfment of extracellular material and extracellular fluid. Pinocytosis is a non-specific process that goes on continually in all cell types, in which the plasma membrane invaginates and forms an inward channel, into which extracellular fluid flows (Figure 1. Solutes dissolved in the extracellular fluid, including large (soluble) macromolecules, may flow with the extracellular fluid into the invaginations and become internalized. Alternatively, uptake may involve: • adsorptive pinocytosis, in which macromolecules bind to non-specific membrane receptors, prior to pinocytosis; • receptor-mediated pinocytosis, in which macromolecules bind to specific membrane receptors, prior to pinocytosis. The pinocytic vesicles (endosomes) migrate inwardly and fuse with lysosomes, which contain many lyosomal enzymes, to form secondary lyosomes. The ligand is degraded by the lysosomal enzymes, the degraded products are released and the membrane is recycled back to the plasma membrane. Alternatively, the secondary lysosomes can fuse with the cell membrane, leading to exocytosis of their contents, and the membranes are recycled back to the plasma membrane. Thus pinocytosis offers a pathway through which large macromolecules, which are otherwise incapable of passing through the membrane, may be taken up by cells. In some cases, following uptake of a drug via receptor-mediated pinocytosis, the endosomes carrying the drug actually bypass the lysosomes and migrate toward the basolateral membrane, resulting in the release of the undegraded drug into the extracellular space bounded by the basolateral membrane. This process, known as transcytosis, represents a potentially useful and important pathway for the absorption of high molecular weight drugs such as peptides and proteins. Indeed, some peptides and proteins are known to enter intestinal mucosal cells through pinocytosis; furthermore, a few peptides and proteins (including immunoglobulin G, nerve growth factor and epidermal growth factor) have been reported to reach blood vessels in the lamina propria and the portal venous circulation. This process may be facilitated by serum proteins knows as opsonins, which cover the particulate and promote adsorption and ingestion. The extent and pattern of opsonization depends highly on antigen surface characteristics such as charge and hydrophilicity. When digestion is complete, the lysosomal membrane may rupture, discharging its contents into the cytoplasm. Fixed macrophages are found lining certain blood and lymph-filled spaces, such as the sinusoids of the liver (these cells are commonly referred to as Kuppfer cells), bone marrow and spleen. For the purpose of completeness, the process of phagocytosis has been described briefly here. The process of phagocytosis is of particular relevance when particulate delivery systems, such as microspheres, liposomes and other advanced delivery systems (described in Chapter 5), are used. Phagocytic processes are also finding applications in oral drug delivery and targeting. Specialized epithelial cells known as M cells, which overly lymphoid sections of the gastrointestinal tract, may be involved in the phagocytic uptake of macromolecules and microparticles from the gut (see Section 6. Pore transport A further mechanism of transcellular transport is via the aqueous pores which exist in many lipid membranes. However, most drugs are generally much larger (≥1 nm in diameter) than the pore size, and this route is therefore of minor importance for drug delivery. These properties will influence the route and mechanism of drug absorption through the mucosa. For example, it is not unreasonable to assume that: • low molecular weight hydrophilic compounds would tend to be absorbed via the paracellular route, moving between the epithelial cells; • lipid-soluble drugs would usually absorbed via transcellular passive diffusion, diffusing through the lipidic membrane barrier; • macromolecules may be absorbed via endocytic processes; • drugs bearing structural similarities to endogenous nutrients may be absorbed via carrier-mediated mechanisms. However, this is a rather simplistic view and it is important to realize that these considerations are only broad generalizations. Thus although a drug molecule may be predominantly absorbed via one particular route/mechanism, it is also likely that suboptimal transport will occur via other routes and mechanisms. In particular, drugs that are absorbed via active mechanisms are often also absorbed, to a (much) lesser extent, via passive diffusion mechanisms. A brief description of the effect of the physicochemical properties of the drug on the absorption process is given below and is discussed in more detail in the relevant chapters. A measure of the lipid solubility of a drug is given by its oil/water equilibrium partition coefficient. This is determined by adding the drug to a mixture of equal volumes of a lipophilic liquid (often octanol, but other solvents also used) and water and shaking the mixture vigorously to promote partitioning of the drug into each phase. For a given drug: if log P=0, there is equal distribution of the drug in both phases if log P>0, the drug is lipid soluble if log P<0, the drug is water soluble 19 Table 1.
I have employed it with success in atonic lesions of the respiratory organs zudena 100 mg lowest price erectile dysfunction 2015, attended with dull pains in the chest order zudena 100mg with mastercard erectile dysfunction and diabetes leaflet, increased by full inspiration buy 100mg zudena with amex erectile dysfunction 45 year old male. There is also a sense of soreness, as if bruised, or that follows very severe exertion. In these cases it exerted a marked influence, relieving the cough and unpleasant sensations; even checking the chills, hectic fever and night sweats, in confirmed phthisis, for some considerable time. The strongest indication for the Sticta will be found in pain in the shoulders, back of the neck, and extending to the occiput. During the past winter I have had occasion to give it in some very unpleasant cases of scarlet fever, and with most marked benefit. Price, of Baltimore, says: - “I have used Sticta in rheumatism very extensively for the past three or four years. I find it most useful in those cases, where, in connection with the larger joints, the small ones are also involved. It matters not whether fingers or toes, there is swelling, heat, and circumscribed redness of the joints. Both have been employed successfully in the treatment of ague, and are powerful stimulants and restoratives. It may be given in acute disease, when the patient is furiously delirious; in delirium tremens when the patient is enraged and inclined to injure those present, destroy the furniture or harm himself; in violent mania; in epilepsy associated with or paroxysms followed by maniacal excitement. In chronic disease it is enough that the patient feels inclined to violent outbursts of passion, and has difficulty in restraining himself. It is in some degree an antidote to the opium habit, and in some cases, if its use is persisted in, it will effect a cure. It is also an excellent remedy in chronic disease of the skin, with hypertrophy and pruritus. An ointment may be prepared from the fresh flowering tops and young leaves, by pouring over them hot mutton tallow, allowing the vessel to remain where it will be kept just below the boiling point for two hours. This ointment will be found an excellent application to hemorrhoids, and in cases of pruritus ani, with hypertrophy of the skin. A solution of the Strychnia may be prepared after the following formula: ℞ Sulphate of Strychnia, grs. Nux Vomica exerts a specific influence upon the intestinal canal and associate viscera that renders it a most valuable remedy. In minute doses we employ it to arrest nausea and vomiting, when this arises from gastric irritability and not from irritant material in the stomach. The cases are those in which there is feebleness of the organs, and not where there is irritation and inflammation. For this purpose we employ it in cholera infantum with marked benefit, and in cholera morbus and Asiatic cholera to relieve this symptom. Given, a feeling of fullness in right hypochondrium, pain in side or shoulder, sallowness of face, yellowness of eyes, yellow coat on tongue, I prescribe Nux Vomica with a certainty that I never felt in the olden time. In bilious remittent fevers, with these symptoms, Nux Vomica is the first remedy indicated. In diarrhœa, with these symptoms, we prescribe it with the certainty that the discharges will be speedily arrested, and the stomach and intestinal canal left in good condition. In dyspepsia, with these symptoms, we obtain speedy and permanent relief from the use of the remedy. It is here, as we have found it in the consideration of other remedies, if you can once determine the exact indication for its use, you may employ it whenever you find these indications, no matter what may be the name of the disease, or the condition of the patient otherwise. It makes no difference whether it is the colic of childhood or of the adult, acute or chronic. It is not a remedy for pain dependent upon irritation with determination of blood, or upon muscular spasm. In addition to the symptoms named, as indicating the use of Nux Vomica, may be named hypochondriac pain, umbilical pain, or pain in forehead associated with nausea; yellowish or brownish maculæ, in chronic disease, are also indications for its use. In some cases, a peculiar yellowish sallow ring around the mouth, will be found indicative of impairment of innervation from the solar plexus, and Nux will prove the remedy. We find this peculiarity in the action of Nux Vomica, which we have noticed with some of the more prominent of the specific medicines, and which, indeed, is true of all - when distinctly indicated, it may be the remedy for the entirety of a disease. Thus, taking a fever presenting the symptoms of nausea, hypochondriac and umbilical pains, full, moist tongue, with slight yellow coat, and sallow skin, Nux Vomica relieves gastric irritation, is promptly sedative, relieving irritation of the nervous system, stimulates secretion - indeed it is promptly curative. Take a case of dysentery with these characteristic symptoms, and relief is speedy and the cure rapid. The influence of Nux Vomica and Strychnia upon the spinal cord is well known, and this seems to be its principal use in medicine. Whilst I think it better, in the majority of cases, to restrict its use as above, there are some in which we employ it for its influence upon the nervous system. These are: - In typhoid and asthenic disease, where there is impairment of spinal innervation, and in consequence imperfect or enfeebled respiration, we give Strychnia or Nux Vomica with advantage. Indeed, in those cases in which the respiratory function can only be carried on under the influence of the will, it is the only remedy we can rely on. In the same classes of disease, the tendency to retention of urine is met by the use of the same remedy. In some cases of the same diseases, where a feeble circulation is associated with general impairment of muscular power and inability to co- ordinate muscular movement, we use Nux Vomica with advantage. Nux Vomica or Strychnia should never be employed in the treatment of paralysis so long as any evidence of inflammatory action exists; neither should it be used, if there are marked evidences of cerebro-spinal congestion, until this is removed. It is the first remedy employed in cases of paralysis presenting the symptoms of visceral derangement we have already named. In other cases it is only employed as a nerve stimulant, when the nerve centers are free from disease. We employ Sulphur as a restorative in those cases in which there is a deficiency of this element in the blood. The indication for the use of Sulphur as a restorative is, enfeebled nutrition associated with decoloration of tissues and secretions. The skin is blanched, the iris loses color, the hair is lighter in color in the young, changes rapidly to gray in the middle aged, and the urine is light colored as is the feces. The presence of cystine in the urine is an indication for the administration of Sulphur. We also employ sulphur in those cases in which there is excessive fetor of the excretions. We will occasionally find a case of chronic disease, in which the breath, the secretion from the skin, the urine, and the feces have a peculiar cadaverous odor, and we notice that with this there is a remarkable tendency to decomposition, and to breaking down of tissue. It is possible that this may be explained, by the necessity of Sulphur in the formation of the taurine of the bile. If this secretion of the liver is the normal antiseptic, and controls putrescency in the body, we can see why a deficiency of Sulphur may lead to the condition above named, and its administration be directly curative. A tincture is prepared from the imported root (Turkestan), using alcohol of 98 per cent.

Well purchase zudena 100mg overnight delivery erectile dysfunction diabetes uk, because getting up and moving increases the naturally occurring feel-good endorphins in the human body buy zudena 100mg with visa doctor's guide to erectile dysfunction. When endorphins order zudena cheap online drugs for erectile dysfunction, substances occurring naturally in the brain that are chemically similar to morphine, spread through your brain, you get a sense of well-being and pleasure. In this chapter, we tell you how much exercise you need to get those endorphins going, and we tell you about all the known beneﬁts of exercise. You pick your top ten reasons for begin- ning or sticking with an exercise program and then ﬁgure out an exercise plan that ﬁts your lifestyle. We also offer some tips for ﬁnding the motivation to keep exercise going in your life. The best time to get into an exercise habit is when you’re young because exercise helps to keep you healthy throughout your life. However, it’s never too late to start — even 90-year- olds beneﬁt from regular exercise! However, for men over 40, women over 50, and anyone with a chronic disease or other health concerns, it’s best to check with a physician before beginning a vigorous exercise regimen. Every ﬁve years, the United States government updates its guidelines for nutrition and exer- cise. The 2005 recommendations signiﬁcantly increased the recommended amount of time for healthy people to engage in vigorous physical activity. Here they are: Children should be physically active about an hour a day on most days. Adolescents should engage in at least 60 minutes of exercise every day, most days of the week. You guessed it — that means you must communicate with your prescriber on a regular basis about the speciﬁc side effects you’re experiencing. Because it’s so important for your healthcare provider to know about your experience with side effects, we created the Side Effect Tracking Form, shown in Worksheet 14-5, for you to ﬁll out and take to your consultations (or use it as a guide during your telephone conversa- tions). We recommend you complete this form at the very least for one month after you start a new medication for depression or anxiety. Is this satisfaction-interrupting thought distorted, and can I come up with a more accurate replacement thought? In the left-hand column, use a few words to capture what should have been a satisfy- ing event. If you initially had satisfying thoughts about that event, record those in the middle column. Estimate the amount of time you’ve devoted to activities that are concordant with your top three values (see Worksheet 18-13). If you notice a discrepancy between what you value and what you do, consider re-prioritizing. In Worksheet 18-14, jot down how you plan to re-allocate your schedule and resources to better reﬂect what you deem as important. Apart from separation anxiety disorder, a well recognized problem of childhood, it is now widely accepted that generalized anxiety disorder, social phobia, specific phobia, posttraumatic stress disorder, obsessive compulsive disorder and panic disorder all occur during the childhood and adolescent years. Numerous studies examining the nature and treatment of anxiety disorders have appeared during the recent years. Significant advances in this area include the investigation of pharmacological agents and development of effective psychosocial interventions. Prevalence rates for having at least one childhood anxiety disorder vary from 6% to 20% over several large epidemiological studies (Costello et. Co-morbidity is extremely common among children and adolescent suffering from anxiety disorders. A recent study of children aged 8 - 13 years, having a primary diagnosis of anxiety disorder revealed that 79% of the sample also had another co-morbid anxiety disorder, mood disorder or behavior disorder (Kendall et. In view of such findings, consideration needs to be given to co-morbidities as their presence will guide selection of specific treatments. The objective of these guidelines is to provide up-to-date information about management of anxiety disorders. Literature was reviewed by a computerized search in the month of June 2007 using the keywords child, adolescent, anxiety disorder, treatment, and management. Articles retrieved and their relevant references were reviewed for the purpose of framing these guidelines. The defining point for caseness is often ambiguous as many childhood anxieties are not only common but also have an adaptive role in human development. If the screening indicates significant anxiety, then the clinician should do a formal evaluation to determine subtype of anxiety disorder, the severity of anxiety symptoms and functional 1. Anxiety may be considered symptomatic when it is impairing and prevents / limits developmentally appropriate adaptive behavior. In addition, the degree of distress and dysfunction associated with anxiety also help in reaching a diagnosis. Anxiety disorders impair emotional, cognitive, physical and behavioral functioning in multiple areas and are usually chronic in nature. Hence, the child needs to be evaluated in context of his family, school, community, and culture. Important areas of assessment include history of onset and development of anxiety symptoms, associated stressors, medical history, school history, family psychiatric history and mental status examination. Early detection and effective treatment may reduce the impact of anxiety on academic and social functioning in youth and may reduce the persistence of anxiety into adulthood. The emphasis has now shifted to the study of diagnostic groups that reflect explicit clinical criteria. A comprehensive evaluation should include a detailed structured or semi structured psychiatric interview to establish the anxiety disorder diagnosis and detect co-morbid psychiatric disorders. In addition, clinical rating scales, self report scales and parent report instruments may be used to determine the type and severity of anxiety symptomatology. Over the last two decades there has been a proliferation of instruments to determine the presence of anxiety disorders in children or quantify levels of anxiety. Assessment instruments include paper- and-pencil scales for children, parents and teachers, as well as child and parent interviews. Interested readers are referred to a review of commonly used instruments by Brooks & Kutcher, 2003. They are used to screen large groups, to examine the relative contribution of genetics and environment, to assess severity and as outcome measures of treatment efficacy. Rating scales that anteceded the present nosology of anxiety disorders were designed to assess a plethora of factors such as worry, physiological anxiety, fear of bodily harm, etc. The limitations of the older rating scales and increasing interest in childhood anxiety disorders has led to development of more sensitive and diagnostically relevant measures of childhood anxiety. Recent efforts reflect the classification of anxiety disorders and a move towards specificity of content, with relevance to diagnostic grouping.
Also discount generic zudena canada impotence after prostate surgery, inappropriate cultural competence and awareness to treat the holistic needs of Black clients by health care 170 providers of other races and ethnicities may further complicate the trust issue and medication adherence outcomes (Barksdale cheap 100mg zudena with amex erectile dysfunction causes heart disease, 2009; Yancy et al order zudena 100mg with mastercard erectile dysfunction caused by lack of sleep. The optimal predictive model in this study revealed that the dynamic variable that had a statistically significant relationship with medication adherence was trust. As trust in the health care provider increased, adherence to medications increased. That is, participants who reported the most trust in their health care providers were more willing to adhere to the prescribed treatment regimen. This finding is congruent to expectations that trust promotes better medication adherence (Benkert et al. Because the sex of participants in the study was not reported, it is unclear whether Black women were included. Although the findings of the current study support currently held beliefs regarding trust and medication adherence, there is reason to consider an alternative viewpoint for clients who may not trust their health care providers. Clients who are distrustful may recognize that their health needs are not satisfied when they are left with superficial directives that are virtually meaningless and impossible to follow. Over time, the clients 171 become symptomatic and gain the label of being nonadherent to the treatment regimen that they may have had no knowledge. In essence, health care providers may not be providing Black clients with the health care information and services necessary to promote healthy lifestyle changes, thus increasing distrust of the health care provider. According to Cox, Sullivan, and Roghmann (1984), multifaceted interventions to manage health problems are required from health care providers. These interventions include combining the client‘s physiological, psychological, sociodemographic, and environmental characteristics to achieve the desired health outcome, such as adherence to antihypertensive medication. Cox (2010, August 4) contends that clients must be involved as participants in the self-care of their health and initially, ample time must be spent to clear up misperceptions, misunderstandings, and misknowledge. Barksdale (2009) concurs and recommends a client-centered approach to delivering health care. Thus, increasing client knowledge, involvement in the treatment process, and devising interventions pertinent to the client‘s needs may be vital to establishing trust and maintaining medication adherence. Stress on the other hand refers to how the body reacts to internal and external experiences. Black women, unlike other racial/ethnic groups, are confronted with the triple jeopardy of racism, sexism, and classism that may overtax coping mechanisms and contribute to insurmountable 172 psychological and physiological stressors (Beal, 1969; Jones & Shorter-Gooden, 2003). Further, 21% of those below the poverty level reported total medication adherence with a perfect Hill-Bone Compliance score. In contrast, two studies showed that coping was associated with mean arterial changes (R. In a study conducted by Shorter-Gooden (2004) on mechanisms to identify coping strategies in Black women, results indicated that those who were resistant to the damaging effects of stress-related health consequences tended to engage in various coping strategies, such as spirituality, social support, and valuing oneself. The age of participants in the current study may have been an influencing factor on their perceptions of racism/discrimination. Therefore, many participants were not directly exposed to the harsh realities of racism/discrimination and may only have experienced subdued forms of racism/discrimination. However, since the election of the nation‘s first Black President, ―silent racism‖ has evolved (Rossing, 2011, p. The term racism has become distorted and downplayed, especially in the political arena, because it signifies racial disunity. Therefore, any racist attacks on the President or other people of color are virtually ignored in the mainstream public discourse (Rossing, 2011). In the current study, perceived racism/discrimination was not related to medication nonadherence. In contrast, several qualitative studies found that perceived racism/discrimination was identified as a factor in nonadherence to antihypertensive medications (L. Clients who feel they are treated unfairly may respond with anger and hostility and be less likely to follow the health care providers‘ treatment advice. Consequently, the impact of racism/discrimination may reflect mistrust and rejection of health care providers and services offered, contributing to poor medication adherence and subsequent poor health outcomes (Chakraborty, King, Leavey, & McKenzie, 2010). Depression in Black women is not fully understood (Read & Gorman, 2007) and may be difficult to detect (Jones & Shorter-Gooden, 2003). Typically, Black women deny depressive symptoms (Duckwork, 2009) and describe depression differently, such as feeling stressed or tired (Jones & Shorter-Gooden, 2003). Therefore, treatment for depression is either not readily sought by Black women, or depression is oftentimes misdiagnosed (Duckwork, 2009). Therefore, capturing the true clinical picture and prevalence of depression in Black women may be elusive. Hypertension was associated with a greater risk of depression in Canadian men, but not women (Patten, 2001). Despite the association of depression and medication adherence, depression was not in the optimal predictive model. Implications for Nursing Hypertension is rampant among Blacks, especially Black women. It is vital to actively engage organizations, such as the American Heart Association, in the education of Black youth. Depression in Black women is oftentimes difficult to detect because many have been socialized to appear strong, tough, and confident even when falling apart on the inside. More psychometrically sound assessment and screening tools are needed that target depression in Black women. Because Black women tend to report they are stressed and cannot name their feeling as depression, help sought from health care providers is usually futile as it addresses stress, not depression. Frustration develops from a lack of sensitivity to their needs 178 and fatalistic attitudes may evolve that hinder their ability to follow the treatment regimen. Oftentimes depression in the Black community is viewed as a weakness and thought to be overcome by reliance on prayer, family, and friends. Support from policymakers is needed for public education programs to aid in dispelling long held beliefs about depression in Black women. Nurses must be diligent in assessing clinical factors, such as depression and fatalism, and in conducting research to identify other factors that may be associated with nonadherence to antihypertensive medications. Increased number of prescribed medications was related to adherence to antihypertensive medications in this study. Participants taking five to seven prescribed medications were likely to be adherent. During assessments, nurses should not only ask clients to name their prescribed medications, but should rate the effect that prescribed medications have on the client‘s daily lives. This evaluation may help nurses determine risk for antihypertensive medication nonadherence. According to a recent study (Abel, Crane, Efird, & Sherer, 2011, February) on predictors of readmission rates in heart failure clients, data revealed that the higher the number of comorbidities, the greater the risk of readmission. With the economic recession in the United States, policymakers are penalizing hospitals with excessive readmission rates in an effort to curve health care costs and decrease government 179 spending. Developing and targeting interventions to those with more comorbidities may be important in controlling risking health care costs.
This translocation alters the activity of the abl proto-oncogene (proto- leukemia (retinoid : buy cheap zudena 100mg on-line erectile dysfunction and urologist. More than 100 different chromosome rearrangements involving nearly every chromosome have been observed in more than 40 types of cancer discount zudena 100 mg with amex impotent rage. If alternate segregation occurs purchase zudena discount trimix erectile dysfunction treatment, the offspring will inherit either a nor- ~,I mal chromosome complement or will be a normal carrier like the. Consequences of a Robertsonian Translocaton in One Parent (illustrated with a male), I " f Robertsonian Translocation and Down Syndrome. Approximately 5% of Down syndrome cases are the result of a Robertsonian translocation affecting chromosome 14 and chromo- some 21. When a translocation carrier produces gametes, the translocation chromosome can, segregate with the normal 14 or with the normal 21. A diagram can be drawn to represent the six possible gametes that could be produced. The key difference is 47 versus 46 chromosomes in the individual with Note,, Down syndrome. The recurrence risk (determined empirically) for female translocation carriers is I carner: 10-15%, and that for male translocation carriers is 1-2%. The elevated recurrence risk for translocation carriers Adjacent segregation versus noncarri~rs underscores the importance of ordering a chromosom~ study when Down produces unbalanced syndrome is suspected in a newborn. Examples include: Prader-Willi syndrome Angelman syndrome If a micro deletion includes several contiguous genes, a variety of phenotypic outcomes may be part of the genetic syndrome. Inversions thatinclude the centromere are termed pericentric, paracentric) whereas those that do not include the centromere are termed paracentric. The karyotype of the inversion shown in Figure 11-3-8, extending from 3p21 to 3q13 is 46,xy,inv(3)(p21;q13)~ • Ring chromosomes Inversion carriers still retain all of their genetic material, so they are usually unaffecte • Isochromosomes (although an in~ersion may interrupt or otherwise affect a specific gene and thus cause disease) Because homologous chromosomes must line up during meiosis, inverted chromosomes. Pericentric Inversion of Chromosome 16 A male infant, the product of a full-term pregnancy, was born with hypospadias and ambiguo genitalia. His brother had two childre " " both healthy, and the father assumed that he would also have normal children. A Pericentric Inversion of Chromosome 3 l Ring Chromosome I 1: A ring chromosome can form when a deletion occurs on both tips of a chromosome and the r remaining chromosome ends fuse together. The karyotype of an isochromo- some for the long arm of the X chromosome would be 46;X,i(Xq); this karyotype results in an individual with Turner syndrome, indicating that most of the critical genes responsible for the Turner phenotype are on Xp. Isochromosome Xq Uniparental Disomy Uniparental disomy is a rare condition in which both copies of a particular chromosome are contributed by one parent. This may cause problems if the chromosome contains an imprinted region or a mutation. For example, 25-30% of Prader- Willi cases are caused by maternal uni- parental disomy of chromosome 15. A smaller percentage of Angelman syndrome is caused by paternal uniparental disomy of chromosome 15. For example, a probe that is specific for chromosome 21 will hybridize in • Deletions, including three places in the cells of a trisomy 21 patient, providing a diagnosis of Down syndrome. Spectral Karyotyping Spectral karyotyping involves the use of five different fluorescent probes that hybridize dif- ferentially to different sets of chromosomes. In combination with special cameras and image- processing software, this technique produces a karyotype in,which every chromosome is "painted" a different color. This allows the ready visualization of chromosome rearrangements, such as small translocations, e. Haploid (23, normal gametes) • Diploid (46, normal somatic cells) • Triploid (69; lethal). A 26-year-old woman has produced two children with Down syndrome, and she has also had two miscarriages. A 6-year-old boy has a family history of mental retardation and has developmental delay " and some unusual facial features. Multiple attempts to have a second child have ended in miscarriages and spontaneous abortions. Karyotypes of the mother, the father, and the most recently aborted fetus are represented schematically below. A woman brings her 16-year-old daughter to a physician because she has not yet begun menstruating. A 38-year-old woman in her 15th week of pregnancy undergoes ultrasonography that reveals an increased area of nuchal transparency. A 37-year-old woman is brought to emergency department because of crampy abdominal pain and vaginal bleeding for 3 hours. Speculum examination shows the presence of blood in the vagina and cervical dilatation. After discussing the condition, with the patient, she gave her consent for dilatation and curettage. As ii translocation carrier, it is possible that she can transmit the translocated chromosome, containing the long arms of both 14 and 21, to each of her offspring, If she also transmits her ~or~af copy of chromosome 21, then she will effectively transmit two copies of chromosome 21. When this egg cell is fertilized by a sperm cell carryinganother copy of chromosome 21, the zygote will receive three copies of the long arm of chromo- some 21. The miscarriages may represent fetuses that inherited three copies of the long arm and werespontaneously aborted during pregnancy. Although the risk for Down syndrome increases if a woman has had a previous child, there is no evidence that the risk increases if a more distant relative, such as a first cousin, is affected (choice A). An extra copy of material from chromosome 14 or 18 (choice D) could result in a miscar- riage, but neither would produce children with Down syndrome, which is caused by an extra copy of the long arm of,chromosome 21. Heavy irradiation has been shown to induce nondisjunction in some experimental ani-. However, many other syndromes also include mental retardation as a feature, so this would not be a specific test. Testicular volume (choice E) is increased in males with fragile X syndrome, but this is observed in postpubertal males. Although the father is a translocation carrier, his genetic material is balanced, not unbalanced (choice E). It should be high on the differential diagnosis list for a female adolescent of short stature who presents with primary amenorrhea. Balanced translocations (choices Band C) have few,if any, consequences on the phenotype,. Deletion of a locus subject to imprinting (choice E) is consistent with Prader- Will syn- drome or Angelman syndrome but is not associated with the phenotype described. The fetus has unbalanced chromosomal material (additional chromosomal material on one copy of chromosome 18). One of the parents is likely to be a carrier of a reciprocal translocation involving chromosome 18 andone other chromosome (unspeci- fied in stem). A Robertsonian translocation (choice B) would result in fusion of q arms from two acro- centric chromosomes. Isochromosome 18(p) indicates, a chromosome 18 with two p arms and no q arms (choice C).
