Somatic innervation to the levator ani muscles is supplied by efferent (motor) nerves specifically arising from the pelvic nerve (originating from spinal cord levels S2-S4) supplying the peritoneal aspect and the pudendal nerve (also from S2-S4) supplying the caudal asthma 9 code buy advair diskus 100 mcg with visa, or perineal, portion. The levator ani muscles maintain a baseline contractile tone that helps to preserve the orientation of the pelvic organs (Parks et al. This constant tone is dependent on proprioceptive afferent input as processed by the dorsal root ganglia in the spine and the normal function of afferent sensory nerves. Humans can voluntarily increase their pelvic muscle contractions, such as in response to an increase in intra-abdominal pressure, but the muscles rapidly fatigue and tone returns to baseline after an average of 1 min (Parks et al. As humans evolved to become bipedal creatures and obtained upright postures, new stress forces emerged that began to be countered by the musculature. The iliococcygeus originates from a connective tissue condensation (termed the arcus tendineus levator ani) of the lateral pelvis near the ilia of the bony pelvis and attaches to the coccyx. This large muscle has a horizontal orientation and coalesces with the pubococcygeus and puborectalis to form the levator plate (median raphe), upon which the upper two thirds of the vagina and the uterus rest horizontally. The urethra, vagina, and rectum descend through the interior of this loop in the space termed the urogenital hiatus. As the levators contract, they apply pressure to these structures and eliminate potential space. Caudal to the levator plate, the vagina and rectum terminate in a vertical orientation. Smooth muscle fibers are also present, primarily contained within viscera, including the bladder, urethra, uterus, vagina, and bowel. They allow for stretch and accommodation during filling of the viscera and evacuation of visceral contents in combination with autonomic reflexes. Smooth muscle cells can be found, to varying degree, within the supportive connective tissue. Many of the components of the pelvic floor are noted to be altered in postmenopausal women or women with prolapse, and the smooth muscle cells are no exception. In orthopedic terminology, ligaments are the dense connective tissue connections bridging from bone to bone whereas tendon is the term given to the connection between a muscle and a bone. A ligament may refer to a fold of peritoneum that formed during embryonic development. An example is the hepatoduodenal ligament, which contains the portal triad of the hepatic artery, portal vein, and the common bile duct. In the pelvis, the ligaments typically refer to the connective tissue suspensions tethering the viscera (such as the uterus, bladder, urethra, vagina, and rectum) to the pelvic sidewall and the bony pelvis. Close to the uterus and cervix it is termed the parametrium, and at the level of the external cervical os it becomes the paracolpium (DeLancey, 1993). This web periodically solidifies into thicker bands called ligaments, which serve to support the internal organs of the pelvis and are primarily bridges between the viscera and bony structures. Level I refers to the support of the vagina at its apex, specifically referring to the cardinal and uterosacral ligaments. More distally, there is also an attachment between the vagina and the arcus tendineus fascia rectovaginalis. Collagen provides the tissue with tensile strength, and elastin provides resilience, which is the ability for tissue to snap back into place after it is deformed or stretched. Other proteoglycans, including fibronectin, vitronectin, and laminin, serve to create cell-to-cell bindings (Tinelli et al. The composition of the connective tissue is dynamic, with production and degradation of collagens occurring as the tissue continuously remodels in response to stresses, aging, and injury. It is thought that hormones may influence the balance of collagen types within the tissues. This group found no difference in the proportion of elastin or smooth muscle between pre- and postmenopausal women. Changes in collagen composition are also likely associated with pelvic organ prolapse. Overall, the changes in collagen likely change the tensile strength of the tissue, a risk factor for prolapse. It is interesting to note that the collagen content is also decreased for women with prolapse in tissues that do not provide structural support, such as the cervix (Wong et al. For example, the rat has connective tissue anatomy that parallels human anatomy in terms of its support. In humans, because of the adoption of an upright posture, the levator ani muscles and the connective tissue structures share the load. When the pelvic floor muscles contract at baseline, the tension applied to and experienced by the supportive ligaments is reduced. If the muscles are damaged, such as may happen after childbirth, or if the nerves that supply the muscles are stretched or otherwise damaged, such that the muscles they supply are compromised, then the shelf supporting the pelvic organs may sag or the uterus, cervix, bladder, and rectum may change their orientation or herniate through the urogenital hiatus. When the organs change their position, additional tension is placed on the supporting connective tissue, which may then stretch or even rupture, leading to observable pelvic organ prolapse. It is likely that vaginal childbirth serves as an initial instigating event for damage, but it is also likely that progressive denervation of the muscles continues to occur as a woman ages. Other risks include chronic increased intra-abdominal pressure or repetitive high-pressure straining, such as occurs for patients with obesity, chronic cough conditions, chronic obstructive pulmonary disease, habitual heavy lifting, or chronic constipation. Recent work has sought to elucidate the biomechanical properties of the pelvic floor.

We used a coaching 138 Successful Practice in Neuropsychology and Neuro-Rehabilitation analogy with which many young men his age were familiar asthma 2015 movie soundtrack buy advair diskus toronto. We used the example of a very skilled baseball player (a sport he enjoyed) with an excellent batting average, who through no fault of his own was now in a major batting slump. Perhaps, there had been some kind of disruption in his "muscle memory" or the natural neural networks that underlay the complex batting process. No matter what he did to simply exert his way out of it, he now rarely got a hit when he was at bat. He was highly frustrated and was not quite sure what to do to fix the problem, as he had never before had to think consciously about his batting style. As a good coach would do, we helped him identify and practice all the components that were likely essential to his naturally good preinjury skills, in this case, memory performances. By trying specific tools and techniques we could see-clinician and patient, together-what helped him and too, what fit with his natural learning style. We then created a version of practice with him, as the baseball coach would have done-only this occurred in the domain of cognitive compensation. His task was to rebuild the strength of those methods and components essential for his new learning and memory performances and to make them habitual. These techniques were integrated with his individual and group treatments and monitored for their use in his home and community settings. With regular practice, he was able to reestablish improved memory performance with the regular use of compensatory techniques. With success in performance, he developed a greater willingness to use the recommended strategies and techniques. It is our job as clinicians to help the patient accurately identify their residual strengths in all domains of function and roles as a first step to establish stable psychological ground upon which they can stand safely while exploring the altered landscape of their function and life. This requires as much information as possible about premorbid vulnerabilities (cognitive, emotional, interpersonal, characterological, physical, and/or communication) as well as current emotional reactions, sense of self, and perceptual accuracy. Neuro-Rehabilitation Program Treatment: Principles and Process Chapter 13 139 (3) Understanding the above information guides us in evaluation and treatment. Can we help our patients develop a healthy balance of awareness, acceptance, and realism as measured by their appropriate use of compensatory techniques and associated improvements in thinking performance, communication, and behavior Working together, can we improve their level of productive activity, interpersonal impact, physical health, and ongoing integration into their best possible life of hope and meaning- even after brain injury While specific clinical tools and techniques are critical, they cannot be used in isolation to produce the best and most meaningful outcomes. Those factors can exert positive or negative effects across a wide swath of patient interactions, diagnostic conclusions, and clinical outcomes. Perhaps, the patients were not fully engaged in the testing process so actual effort was too low or too inconsistent for valid results. Perhaps, the patients were feeling more anxious than they appeared, so that simply managing that anxiety was taking a significant portion of their energy and focus. Regardless of any nonneurological sources of disruption in performance, 140 Successful Practice in Neuropsychology and Neuro-Rehabilitation distinguishing between scores that technically fall into the ranges of impaired performance versus a true neurological impairment, which is a key part of our accurate analysis. Even if we are highly experienced clinicians, it is sometimes not clear how to parse the relative contribution of acquired neurological disruptions versus premorbid thinking or personality styles. Our patients benefit if we hold our diagnostic conclusions as working hypotheses open to further correction or refinement. Clinicians are Not Blank Slates We clinicians also bring our own sets of biases, perceptual filters, personality strengths and weaknesses, experiences, beliefs, attitudes, tendencies, and blind spots. Our patients will benefit from our clear-mindedness in understanding our motivations for becoming helping professionals. For example, if an essential sense of our value as people comes from patient appreciation for our clinical efforts, we will create trouble for patients and ourselves. If this is the implicit agreement that we are striking with patients, "I will work myself as hard as possible on your behalf and you will show your gratitude by not challenging my advice and by improving steadily," we have misunderstood where our meaning best resides. More, we are creating a therapeutic dynamic that is conflict-laden and ultimately counterproductive. We can be more clinically effective (and less stressed) if we understand that our dedication to some patients may exceed their commitment to improve. Our value as professionals resides in the integrity of our knowledge base, in our degree of preparation, and in our willingness to develop our treatment skills and to accept corrective feedback regarding our performance. Adhering to these tenets will help reduce the chances that we will become burned-out. This kind of self-awareness and commitment to our own lives helps reduce the chances that we would unwittingly retaliate against patients or their families when we are disappointed by them. This retaliation is usually subtle Neuro-Rehabilitation Program Treatment: Principles and Process Chapter 13 141 and often masquerades as benign treatment decisions. It can occur as a result of feelings of frustration with patients who may find their only postinjury power lies in thwarting the efforts of rehabilitation teams. The retaliation may take the form of prematurely discharging patients from therapy or privately giving up on them while we still continue to treat them. These recognitions affect our understanding of patients and improve our interactions with them. This awareness can also deepen our understanding of our team members and can mitigate problems with them.

You might create a group of younger patients and another group for middle-aged or older patients asthma treatment long acting beta agonist advair diskus 100 mcg purchase with visa. For example, the younger patient may not be as well established in his or her work and personal life and may need extra time and attention to examine how one focuses on achieving success in life. The older patient may have already established a successful career or family life that has now been jeopardized: it is this well-established life that he or she is trying to reestablish. Finally, some practitioners prefer groups of patients whose injuries or illnesses are more recent in onset, and who are still struggling to understand and manage this new reality. For some patients, being in a group with others who share their disease or injury is very important and they prefer not to be part of a diagnostically mixed group. While I am always open to these patient preferences, I think there is also much to be gained by patients when they encounter others whose diseases differ. Young patients with malignant brain tumors, for example, who are trying to live a life of quality and meaning in their limited remaining time, can be an important reality check for other members of the group, who may feel How to Design and Implement a Cognitive Group Chapter 14 169 overwhelmed by their own changes in cognitive or physical function. Patients can develop an improved sense of perspective when they encounter someone whose plight is more severe than their own. They have the opportunity to observe, for example, a younger and healthier man with a severe brain stem injury, and its profoundly limiting effect on his motor and speech abilities. Although it is a truism that there is always someone who has it better than you and someone else who has it worse, that is not the only lesson I hope group members will learn. I hope they learn an increased appreciation of the connection and commonality that humans share when we are engaged in any kind of serious struggle. This awareness and acceptance of a common reality can also reduce feelings of isolation and aloneness that certainly afflict all humans. So, even when you do not set out to conduct group psychotherapy, any set of people in group treatment are likely to take away this kind of unspoken new learning. There are also practical factors that play a role in patient selection and development of an effective cognitive group. For example, I do not have the luxury of time, space, and staff to provide group treatments for patients by diagnoses. Thus, for many reasons, I have found that it is often effective to include a broad mixture of diagnostic groups, with varying levels of age and chronicity, as long as two conditions are met: the majority of the group members must have common problems and goals, and they must have common levels of basic abilities and deficits. For example, you may lead a successful cognitive group with patients whose ultimate goal is either to return to some form of paid employment or to maximize their productivity in volunteer work settings. Although some patients have mild injuries and some more severe injuries, they are united by the common realities of being capable of working and able to learn and use compensatory techniques. Further, they share a common goal of achieving effective function in the workplace, which may also include improved social interactions. Some basic 170 Successful Practice in Neuropsychology and Neuro-Rehabilitation group member criteria I use for patients with brain injury or disease are as follows: 1. There is no history of assaultive or violent behavior, unless clear improvements have been maintained for 1 year prior to entering the group. Unless the patient is already well known to you or to a trusted colleague, it is important to hold a preliminary screening interview with them. Once you have satisfied yourself with respect to the above issues, you can proceed to have the patient sign a consent for treatment, supply you with necessary insurance information, and sign a form that indicates he or she will be responsible for fees. Attendance, Participation, Confidentiality, Respect I review the screening criteria with patients at the time of the screening interview, and again at the first meeting of the group. Thinking deficits are a very personal kind of loss, and the feedback from other patients is likely to be far more effective if people are familiar with norms of group behavior and have formed an attachment to each other and to the group leader. Patients are expected to attend each session, since their presence, participation, and observational skills are critical to the therapeutic value of the group. While there are the usual exceptions such as illness, patients are obliged to let me know of any scheduling problems. Ideally, the patient will also mention this within the group, to let the other patients know in advance. Although patients are expected to be present, involved, and as attentive as possible, they are not required to speak in the group, unless responding to questions. Some patients-with varying degrees of aphasia, for example- may find it much easier and more comfortable to listen and to speak only occasionally. Even so, they benefit from the group discussions and they can learn to incorporate new coping strategies into their daily lives. I repeatedly remind members that confidentiality is expected from all participants: Any discussions that reveal information about any patients are not allowed to ever leave the group. While cognitive group members are welcome to take their notebooks and handouts home and to discuss the general themes and issues reviewed, they How to Design and Implement a Cognitive Group Chapter 14 171 are not to reveal details of what other members have said nor the names of other group members. I also caution everyone to be careful about initiating personal conversations with other group members in the waiting areas, where other patients or family members may be present. Those individuals are not part of the group and what transpires there is protected. This is why basic group management skills are essential to effective group leaders. Use of Co-Leaders If you are a relatively inexperienced practitioner I encourage you to engage the services of a co-leader until you feel comfortable and effective. Furthermore, I think the use of co-leaders is always ideal, although it is not always possible.

The volume remains stable because the fetus also regularly urinates into the amniotic sac asthma definition keen purchase advair diskus with a visa. Developing placenta Uterus Chorionic villus the allantois serves as the foundation for the developing umbilical cord. Amniotic cavity the chorion-the outermost membrane-surrounds the other membranes. In the area of the umbilical cord, the chorion forms what will become the fetal side of the placenta. The yolk sac produces red blood cells until the sixth week, after which this task is taken over by the embryonic liver. Besides contributing to the formation of the digestive tract, the yolk sac provides nutrients and handles waste disposal. Placenta and Umbilical Cord About 11 days after conception, the embryo develops a disc-shaped, pancake-like organ called the placenta. The placenta plays a dual role: it secretes hormones necessary to maintain the pregnancy; it also becomes increasingly important in supplying the embryo, and later the fetus, with oxygen and nutrition. As shown in the following figure, these extensions grow into the endometrium like the roots of a tree, forming early chorionic villi. Umbilical cord Chorion As the villi project deeper into the endometrium, they penetrate uterine blood vessels, causing maternal blood to pool around the villi in sinuses called lacunae. Eventually, blood vessels from the umbilical cord extend into the villi, effectively linking the embryo to the placenta. Maternal blood vessels Umbilical vein Umbilical arteries Placenta Amnion Amniotic fluid Yolk sac the umbilical cord contains two umbilical arteries and one umbilical vein. Eventually, the fetal heart pumps blood into the placenta via the umbilical arteries; the blood returns to the fetus by way of the umbilical vein. Instead, the chorionic villi are filled with fetal blood and surrounded by maternal blood. Maternal artery Maternal vein Fetal waste products move from fetal blood in the umbilical arteries to the maternal blood; the maternal veins carry away the waste for disposal. Oxygen, nutrients, and some antibodies pass from the maternal blood-which is pooled in the lacunae around the chorionic villi-to fetal blood in the umbilical veins of the placenta. Umbilical vein Umbilical artery Unfortunately, some toxins such as nicotine, alcohol, and most drugs can also cross the placenta. The placenta also serves an endocrine function, secreting hormones necessary for the continuation of the pregnancy. The test carries certain risks, however, including miscarriage, infection, or the leakage of amniotic fluid. Life lesson: Twins Most twins result when two eggs are ovulated and then fertilized by separate sperm. These twins- called dizygotic or fraternal twins-do not have the same genetic information. Each twin implants on a different part of the uterine wall, and each develops its own placenta. In this instance, the twins are the same sex and carry identical genetic information; they are called monozygotic or identical twins. Monozygotic twins almost always share the same placenta, although each develops in a separate amniotic sac. This is primarily a stage of growth, as the organs that formed during the embryonic period grow and mature. Because the fetus depends on the placenta for oxygen and nutrients as well as for the removal of waste products, the circulatory system of the fetus differs significantly from that of a newborn. In the fetus, neither the lungs nor the liver requires a great deal of blood: the lungs are nonfunctioning and the liver is still immature. The foramen ovale, an opening between the two atria, shunts blood directly from the right atrium to the left. The ductus arteriosus diverts blood from right ventricle to the pulmonary artery, bypassing the lungs. Foramen ovale 3 Inferior vena cava 3 4 Blood flows into the right atrium; most of the blood flows directly into the left atrium through the foramen ovale, bypassing the lungs. Oxygen content of blood High Mixed Ductus venosus 2 the blood that does not flow through the foramen ovale flows into the right ventricle and then into the pulmonary trunk. From there, the blood flows through the ductus arteriosus and into the descending aorta, again bypassing the lungs. Low Umbilical vein 1 Fetal umbilicus Common iliac artery 5 Oxygen-depleted, waste-filled blood flows through two umbilical arteries to the placenta. The placenta then cleanses the blood-ridding it of carbon dioxide and waste products- reoxygenates it, and returns it to the fetus through the umbilical vein. As soon as the lungs are called upon to supply the fetus with oxygen, they demand a larger supply of blood. To meet this need, the ductus arteriosus closes so that blood no longer bypasses the lungs. Then, when blood flows into the left atrium after circulating through the lungs, the newly arriving blood increases the pressure in the left atrium. The increased pressure pushes back the flaps of the foramen ovale and closes the hole. Finally, the ductus venosus deteriorates, eventually becoming a ligament in the liver. The umbilical vein carries oxygenated blood away from the placenta and toward the fetus. During the last six months, the organs that formed during the embryonic stage mature and become functional. As a result, he must work hard with every breath, exerting considerable energy just to reinflate the alveoli.

Potassium Potassium is the chief cation of intracellular fluid asthma risk factors buy advair diskus 500 mcg, just as sodium is the chief cation of extracellular fluid. For example, potassium is crucial for proper nerve and muscle function (which also depends upon adequate levels of sodium). Furthermore, aldosterone regulates serum levels of potassium, just as it does sodium. Rising potassium levels stimulate the adrenal cortex to secrete aldosterone; aldosterone causes the kidneys to excrete potassium as they reabsorb sodium. Potassium Imbalances Imbalances in potassium-the chief electrolyte of intracellular fluid-can develop suddenly or over a long period of time. It may develop suddenly following a crush injury or severe burn (as damaged cells release large amounts of K into the bloodstream). It may also develop gradually from the use of potassiumsparing diuretics or renal insufficiency. Hyperkalemia makes nerve and muscle cells irritable, leading to potentially fatal cardiac arrhythmias. Hypokalemia causes K to move out of cells into plasma, making cells less excitable. Hypokalemia results in muscle weakness, depressed reflexes, and cardiac arrhythmias. Plasma calcium levels are regulated by parathyroid hormone, which affects intestinal absorption of calcium and enhances the release of calcium from bones. Hypercalcemia inhibits depolarization of nerve and muscles cells, leading to muscle weakness, depressed reflexes, and cardiac arrhythmia. Hypocalcemia increases excitation of nerves and muscles, leading to muscle spasms and tetany. Chloride and Phosphate Chloride, the most abundant extracellular anion, is strongly linked to sodium. Chloride contributes to the formation of stomach acid and also helps regulate fluid balance and pH. Phosphate participates in carbohydrate metabolism, bone formation, and acid-base balance. Electrolyte activity, too, can be profoundly affected by changes in pH, as can that of hormones. Acids and Bases the pH of a solution is determined by its concentration of hydrogen (H) ions. For example, anaerobic metabolism produces lactic acid; the catabolism of nucleic acids produces phosphoric acids; and the catabolism of fat produces fatty acids and ketones. A buffer is any mechanism that resists changes in pH by converting a strong acid or base into a weak one. Chemical Buffers Chemical buffers use a chemical to bind H and remove it from solution when levels rise too high and to release H when levels fall. The three main chemical buffer systems are the bicarbonate buffer system, the phosphate buffer system, and the protein buffer system. Each system uses a pair of chemicals: a weak base to bind H ions and a weak acid to release them. The bicarbonate buffer system-the main buffering system of extracellular fluid-uses bicarbonate and carbonic acid. Note that this reaction is reversible: it proceeds to the right when the body needs to lower pH, and it proceeds to the left when pH needs to be raised. If more hydrogen ions are added to the system, some of the added hydrogen ions will react with the bicarbonate ions to produce carbonic acid. Binding with bicarbonate removes the hydrogen ions from the solution and raises pH. When more hydrogen ions are removed from the system, more carbon dioxide will combine with water to produce more carbonic acid. Chemical buffers respond first, followed by the respiratory system and, finally, the renal system. Chemical buffers often restore blood plasma to a normal pH within a fraction of a second. At the same time, they also reabsorb bicarbonate, the predominant buffer in extracellular fluid. This double effect makes the renal system the most powerful of all the buffer systems. The key to understanding the acid-base buffer system is to realize that the body operates within a very narrow pH range. An excess of carbonic acid (resulting in a gain in acid) causes the scale to dip toward acidosis. As discussed previously, potassium imbalances can cause life-threatening cardiac arrhythmias. As the body tries to achieve acid-base balance, H moves out of the plasma and into the cells. Because plasma contains a low concentration of H, H moves out of cells and into plasma; at the same time, K moves out of the plasma and into the cells. Renal Compensation Although the kidneys are the most effective regulators of pH, they take hours or even days to respond to an acid-base imbalance. Alkalosis, on the other hand, makes the nervous system more excitable, resulting in symptoms such as tetany and convulsions. Which factor determines the amount and direction of fluid that flows between body compartments Chloride is the most abundant extracellular anion and is strongly linked to sodium.

Transurethral cystoscopy is well suited to pelvic surgery performed via a vaginal approach but is inconvenient in conjunction with an abdominal procedure in the supine position asthma lung cancer buy advair diskus 250 mcg without a prescription. Valuable operative time is lost by closing the abdominal wound to permit repositioning to lithotomy position and prepping for transurethral cystoscopy. Moreover, any significant cystoscopic findings mandate reopening the abdomen for surgical correction. Suprapubic teloscopy addresses this dilemma by providing a way to perform endoscopy via an abdominal approach. Because of the simplicity of the technique, suprapubic teloscopy compares favorably with the alternatives of open cystotomy or dissection of ureters in terms of required operating time and morbidity. Suprapubic teloscopy is an extraperitoneal technique that begins with closure of the anterior peritoneum to prevent contamination of the peritoneal cavity with spilled urine. If indigo carmine is to be used to help identify the ureteral orifices, it should be given at this juncture to permit time for renal excretion. The bladder cavity is filled through a triple-lumen transurethral Foley catheter to at least 400 mL. A 1- to 2-cm purse-string suture is placed into the muscularis layer of the dome of the bladder, using a No. Two absorbable stay sutures can be placed within the purse-string but with a full-thickness purchase to facilitate introduction of the telescope. A stab incision made between the stay sutures provides an opening for insertion of the telescope. Because distention of the bladder is achieved through the transurethral catheter, the sheath and bridge are unnecessary and the telescope is inserted alone. A 30-degree telescope provides the best view of the trigone and ureteral orifices while also permitting a thorough bladder survey. Identifying the transurethral Foley catheter bulb and locating the trigone beneath the bulb are useful to provide orientation. If suprapubic catheterization is planned, the catheter can be placed through the same stab incision when teloscopy is completed. Ureteral catheters are available in various sizes and with a number of specialized tips. The most useful catheters for assessing ureteral patency are the general-purpose catheter and the whistle-tip catheter. Although available in sizes from 3- to 12-French, the most useful catheter calibers are in the 4- to 7-French range. Once the ureteral orifice is located, the ureteral catheter is advanced into the field of view. Although the deflecting mechanism of the Albarran bridge facilitates ureteral catheterization, it is usually not essential to its completion. The catheter is placed just outside the fenestrated end of the cystoscope, with the catheter tip oriented in the axis of the ureteral lumen. Once the tip enters the ureteral orifice, the catheter is gently advanced until it meets resistance as it passes into the renal pelvis, which is generally 25 to 30 cm. If the catheter is to be left in place, it should be secured to a transurethral catheter and connected to a drainage device. The use of a glide wire or fluoroscopy with retrograde passage of contrast medium also facilitates safe catheter passage. Other potential complications include perforation and ureteral spasm, but with proper methods, the risk of complication is small. Cystourethroscopic Findings Normal Findings the urethral mucosa is normally pink and smooth, with a posterior longitudinal ridge called the urethral crest. In its normal state, the bladder mucosa has a smooth surface with a pale pink to glistening white hue. The translucent mucosa affords easy visualization of the branched submucosal vasculature. As the mucosa of the dome gives way to the trigone, it thickens and a granular texture develops. A thickened white membrane with a villous contour commonly covers the reddened granular surface of the trigone. The interureteric ridge is a visible elevation that forms the superior boundary of the trigone and runs between the ureteral orifices. The intramural portions of the ureters can often be seen as they course from the lateral aspect of the bladder toward the trigone and ureteral orifices. There is marked variation in the ureteral orifices, but they are generally circular or slitlike openings at the apex of a small mound. With efflux of urine, the slit opens and the mound retracts in the direction of the intramural ureter. When distended, the bladder is roughly spherical, but numerous folds of mucosa are evident in the empty or partially filled bladder. The uterus and cervix can usually be seen indenting the posterior wall of the bladder, which creates posterolateral pouches where the bladder drapes over the uterus into the paravaginal spaces. At times, visualization of the bowel peristalsis is possible through the bladder wall. Operative Cystoscopy Urologists most commonly perform operative cystoscopy, although there are several minor procedures that are easily performed in the office by a urogynecologist. These include biopsy of mucosal lesions, removal of small foreign bodies or intravesical sutures, and intravesical botulinum toxin type A injection. Because the focal length of the optics provides the best view immediately in front of the telescope, this is where operative procedures should take place. After introduction of the cystoscope into the bladder and instillation of a sufficient volume of fluid to view the entire bladder wall, the instrument is introduced into the operative port and advanced until it is visible just at the end of the cystoscope.

You would not be able to determine this solely on the basis of information about their age and education. Jones, I have recently opened a neuropsychological practice in this area, and I would be happy to assist with evaluations for any of your adult patients with neurologic problems that might affect brain function. Jones: I have recently opened a neuropsychological practice in this area and hope to have the opportunity to speak with you and your colleagues about services that may be helpful to your patients and practice. My primary areas of neuropsychological practice have included evaluation and treatment of patients ages 16 and above, primarily of working age, who have suffered traumatic brain injury, multiple sclerosis, brain tumors, and other neurologic illnesses. The focus of evaluation for these patients has been to identify residual cognitive and neurobehavioral abilities and deficits and to provide specific treatment recommendations to improve day-to-day function and/or clarify diagnostic questions. I have enclosed a copy of my vitae for more detailed information about my training and experience. I would be happy to give a brief formal presentation to your group on the clinical utility of neuropsychological evaluations, or perhaps upon test patterns and implications for a specific diagnostic group. I will plan to call you next week to see if we might meet, and if a presentation from me is something that might be agreeable to you and your staff. In the meantime, please feel free to contact me directly if you have any questions. Education and training in clinical neuropsychology has evolved along with the development of the specialty itself. Nevertheless, there has been no widely recognized and accepted description of integrated education and training in the specialty of clinical neuropsychology. The aim of the Houston Conference was to advance an aspirational, integrated model of specialty training in clinical neuropsychology. The committee selected a group of 37 clinical neuropsychologists to reflect diversity in practice settings, education and training models, specializations in the field of clinical neuropsychology, levels of seniority, culture, geographic location, and sex. It is predicated on the view that the training of the specialist in clinical neuropsychology must be scientistpractitioner based and may lead to a combined, primarily practice, or primarily academic career. The scientist-practitioner model (Belar & Perry, 1992) as applied to clinical neuropsychology envisions that all aspects of general neuropsychology and professional education and training should be integrated; this is the "horizontal" dimension of education and training. Integration should begin with doctoral education and should continue through internship and residency education and training; this is the "vertical" dimension of education and training. This model defines exit criteria and provides tracks and means for obtaining these criteria across all levels of education and training. Exit criteria for the completion of specialty training are met by the end of the residency program. The programmatic level at which these criteria are achieved may vary but not the content. The clinical neuropsychologist specializes in the application of assessment and intervention principles based on the scientific study of human behavior across the life span as it relates to normal and abnormal functioning of the central nervous system. Persons who engage in the specialty practice of clinical neuropsychology or supervise the specialty practice of clinical neuropsychology. Persons who call themselves "clinical neuropsychologists" or otherwise designate themselves as engaging in the specialty practice of clinical neuropsychology. Psychologists who engage in educating or supervising trainees in the specialty practice of clinical neuropsychology. These core domains are assessment, intervention, consultation, supervision, research and inquiry, consumer protection, and professional development. The scientific activities of the specialist in clinical neuropsychology can vary widely. The specialist whose professional activities involve diverse cultural, ethnic, and linguistic populations has the knowledge and skills to perform those activities competently and ethically. The essential knowledge and skill competencies for these activities are outlined below. This core knowledge may be acquired through multiple pathways, not limited to courses, and may come through other documentable didactic methods.

Vestibule: this structure asthma symptoms last purchase advair diskus 500 mcg on-line, which marks the entrance to the labyrinths, contains organs necessary for the sense of balance. Oval window Cochlea: this snail-like structure contains the structures for hearing. The middle compartment is a triangular duct (called the cochlear duct) filled with endolymph; the outer two compartments are filled with perilymph. Cochlear duct (with endolymph) Perilymph Resting on the floor (called the basilar membrane) of this duct is the organ of Corti, the hearing sense organ. What we can hear depends on how loud a sound is (the volume) as well as its pitch. Human ears can respond to sounds having a pitch between 20 Hz (vibrations per second) and 16,000 Hz. For example, cats can hear sounds up to 60,000 Hz, and bats can detect frequencies as high as 120,000 Hz. Hairs Tectorial membrane the organ of Corti consists of a layer of epithelium (composed of sensory and supporting cells). Thousands of hair cells project from this epithelial layer and are topped with a gelatin-like membrane called the tectorial membrane. Movement here stimulates the hairs of the organ of Corti to send nerve impulses along the cochlear nerve. Anything that interferes with the transmission of vibrations to the inner ear will result in a hearing loss. For example, fluid in the middle ear (as a result of an infection, cold, or allergies), impacted cerumen, or a foreign body will all block the transmission of vibrations. A more serious type of conductive hearing loss is otosclerosis, a condition in which the auditory ossicles fuse together. This type of hearing loss most often results from the death of hair cells in the organ of Corti, usually a result of frequent exposure to sustained loud noise (such as that experienced by factory workers and musicians). Once the hairs are damaged, they never grow back, making this type of hearing loss permanent. This arrangement allows each canal to be stimulated by a different movement of the head. Within each ampulla is a mound of hair cells topped by a gelatinous cone-shaped cap called the cupula. The lightweight cupula floats in the endolymph that fills the semicircular canals. Cupula Hair cells Utricle Inside the vestibule are two sense organs: the utricle and saccule. The tips of the hair cells are covered by a gelatin-like material; embedded throughout the gelatin material are heavy mineral crystals called otoliths. The semicircular canals are primarily concerned with the speed and direction of head movements (dynamic equilibrium). In contrast, the utricle and saccule share responsibility for detecting the position of the head when the body is stationary and also for the sense of acceleration when moving in a straight line (such as when riding in a car). Gravitational force When the head rotates, the endolymph inside the ampulla lags behind. When the movement stops, the endolymph swirls past the cupula, bending it in the process. This pulls on the hair cells, stimulating nearby nerve receptors to send a signal to the brain via the vestibular nerve. The brain interprets the information and triggers the responses necessary for maintaining balance when the head or body is suddenly moved. Inside the vestibule, the otoliths remain level on the hair cells when the head is level, causing minimal stimulation. When the head tilts (or when the entire body moves forward), the membrane and the otoliths shift, stimulating the hair cells. Accessory Structures of the Eye Eyebrow: Perhaps the most significant role of eyebrows is to enhance facial expressions, aiding in nonverbal communication. Eyelids (palpebrae): Formed primarily by the orbicularis oculi muscle covered with skin, the upper and lower eyelids protect the eye from foreign bodies and block light when closed to allow for sleeping. Lateral canthus Medial canthus Palpebral fissure: this is the opening between the lids. Lower eyelid Tarsal glands: these glands, which lie along the thickened area at the edge of the eye (called the tarsal plate), secrete oil to slow the evaporation of tears and help form a barrier seal when the eyes are closed. Eyelashes: these hairs along the edges of the eyelids help keep debris out of the eye. Conjunctiva: the conjunctiva is a transparent mucous membrane that lines the inner surface of the eyelid and covers the anterior surface of the eyeball (except for the cornea). It is very vascular, which becomes apparent when eyes are "bloodshot," a result of dilated vessels in the conjunctiva. Upper eyelid Lacrimal Apparatus the lacrimal apparatus consists of the lacrimal gland and a series of ducts (which are also called tear ducts). Lacrimal gland: this small gland secretes tears that flow onto the surface of the conjunctiva. Furthermore, tears contain a bacterial enzyme called lysozyme that helps prevent infection. Nasolacrimal duct: this passageway carries tears into the nasal cavity (which explains why crying or watery eyes can cause a runny nose).

Ironically, in my private practice years I also found it far easier to protect large blocks of time for record review, test data review, report preparation, journal reading, and various writing and research projects than has ever been true in the institutional setting. I also had more space in which to work than the typical institutional office provides. For me personally as a neuropsychologist I did not have as extensive a range of complex neurological cases in my years of private practice as I was able to see in the academic medical setting. While I was able to pull from several diagnostic groups by working on contract in a medical center combined with my own private referrals, I was still missing some major evaluation groups. By working as a contract consultant for a private rehabilitation company I had weekly or biweekly discussions with their key clinicians and neuro-rehab teams, but it was a periodic consultative rather than integral daily clinical role. This approach allows for an ongoing refinement of your activities, in a manner that hopefully avoids or reduces some of the more egregious effects of bureaucracies and institutions and that offsets some of the negative aspects of private practice. One way to maximize what institutions have to offer is to select an institution and department that you like and to negotiate a part-time contractual relationship with them (see Chapters 4 and 5 for more details). In this manner, you may be able to see patients who would not typically come to your private practice, but whose neurologic problems may be of great interest to you. You can also charge an hourly fee to the facility for your time and let them handle billing and collections. It is only when changes in referral patterns or billing practices are threatened that you may need to take a more active role in problem resolution with regular staff. Neuropsychologists must not neglect to update and expand their knowledge in the areas of the Challenges of Practice in Neuropsychology Chapter 1 3 neuroanatomy, neuropathology, and basic neurobehavioral issues associated with various diseases and syndromes once they have graduated from formal training. Although annual professional conferences and journal articles help, there is nothing like observation and discussion with expert colleagues to promote new growth in our own neuronal systems. You may need to expand or supplement your reading of professional journals and develop a regular journal club meeting with colleagues. These activities can expose you to new knowledge and help ensure that you regularly hear informed perspectives on professional matters. Two helpful avenues for ongoing development of your skills include reviewing specific cases with other neuropsychologists who may have special areas of interest or developing an ongoing consultation relationship with a more experienced neuropsychologist. These two groups can be particularly important for neuropsychologists, who need to be at the top of their form with respect to specific testing knowledge and broader neurobehavioral issues. The latter includes adequate understanding of the disease or injury from a medical standpoint, especially as it is likely to affect neuropsychological functions. There are also workshops, conferences, new books, and new test training opportunities. Although one may need to be selective, sharing the cost and use of these resources can be a very helpful approach in private practice. For some conferences, you and your colleagues may decide to rotate attendance, with the attendee bringing back specific ideas, reprints, and tapes to share. When we fly to a conference, give a talk, or attend a workshop, we not only bear the full training expense, but we must also continue to cover our rent and other overhead, while not earning any income during the time we are away. I am not sure if that constitutes a triple whammy, or merely a double whammy, but it is one of the more challenging aspects of self-employment. Fortunately, a sole proprietor can keep an income stream flowing by hiring neuropsychologists to conduct evaluations in your absence, in a manner prenegotiated with some of your referral sources (see Chapter 7). Such a team typically includes speech language pathologists, occupational therapists, physical therapists, vocational rehabilitation counselors, social workers, recreational therapists, clinical psychologists and neuropsychologists, and rehabilitation medicine physicians. The absence of this kind of team was especially problematic for my patients of working age. For them, well-integrated team treatments are often critical if they are going to resume competitive employment and reestablish a more normal life of work, love, and play. I also made recommendations for further work-up by other disciplines as appropriate for my evaluation patients. If the patient needed only a single service or treatment, it was a relatively simple matter to refer them to a good clinician. It was otherwise a source of concern and frustration to witness the piecemeal and poorly integrated help some patients wound up receiving because they needed several different kinds of therapy and their various practitioners were scattered throughout the city. There was often no clear case manager and no good forum for effective communication among those providers. Perhaps this varies significantly from city to city throughout the United States and Canada, or it may be different in other countries. In America, it seems relatively easy to find similar practitioners self-employed together. One obvious solution is to form good working relationships with as many of the various institution-based and private outpatient programs in the larger community as possible. One further advantage to starting out in an institution or program prior to becoming self-employed is that you have firsthand appreciation for the respective strengths and limitations of each program. You can then more effectively direct your own patients to programs likely to meet their treatment needs. It is also possible to develop good working systems with therapists from various private practices who get to know one another over time through you and through patients that you have sent them to treat. It is important in this circumstance to make sure that someone has been designated as the clinical team leader. Sometimes the attending physician capably fills this role alone; at other times, an experienced rehabilitation therapist or neuropsychologist may need to the Challenges of Practice in Neuropsychology Chapter 1 5 monitor all of the treatment elements.
