This usually occurs with axial compression from trauma bacteria biofuel purchase flagyl 250 mg with amex, excessive load bearing papillomavirus order flagyl 400mg with mastercard, or a reduction in the bony integrity of the endplate and underlying cancellous bone virus quarantine meaning flagyl 400 mg low cost. Longstanding intravertebral herniations are usually considered a coincidental finding antibiotics for dogs for kennel cough discount 250mg flagyl. Intravertebral herniations are those disc derangements which extend into the vertebral bodies antibiotic expiration 400 mg flagyl fast delivery. Intervertebral herniations extend outward from between the margins of the adjoining vertebral bodies antibiotics overview discount flagyl 500mg visa. Intravertebral herniations occur when the disc breaks through the vertebral endplate of an adjoining vertebra. This sagittal T2 weighted image reveals a large intravertebral herniation through the inferior endplate of L1. This is not how the disc typically appears, but it aids in understanding the concept of classifying disc derangements. For the sake of clarity we will treat the intervertebral disc as a symmetrical oval as we describe the nomenclature of classifying disc derangements. Disc bulges are categorized as disc migration (beyond the border of the vertebral apophyses) of more than 50% (180) of the disc circumference. Symmetrical bulging discs have a symmetrical appearance of bulging between 50 and 100 percent of the disc circumference. Herniations, by contrast, are disc derangements which involve less than 50% of the circumference of the disc. Asymmetrical disc bulges are categorized as disc derangements that are asymmetric, but involve outward migration of disc material of at least 50% of the discs circumference. Asymmetrical bulging discs have an asymmetrical appearance of bulging greater than 50% of the discs circumference. It is categorized as a bulge rather than a herniation since it occupies more than 50% of the circumference of the disc. The white arrows identify the boundary of the vertebra and the yellow arrows, the boundary of the disc bulge. Disc herniations are migrations of disc tissue more localized in appearance and occupying less than 50% of the discs circumference. This herniation affects less than 50% of the disc circumference, so it would be labeled a herniation rather than a bulge. A focal disc herniation herniation occupies 25-50% of the occupies less than 25% of the disc disc circumference. A disc extrusion mushrooms out so that it will have a narrowed waist at the base as indicated by the arrows. An extrusion is demonstrated on axial imagery by either the narrowed waist that joins the herniated portion of the disc with the rest of the disc or by the absence of a clear bridge between the herniated portion and the main body of the disc. The red arrows indicate the space between the vertebral body and the extruded disc. Note that the base of these herniations are wider that the tips, and there is no narrowed waist. A protrusion is a herniation that has a wide proximal base which narrows as it extends distally from the center of the disc. An extrusion has an expansive herniation that widens after it leaves the intervertebral space. Even if the herniation appears to have a wide base like a protrusion, it is considered an extrusion if it expands along the vertebral body to a width wider than that of the disc (see image on right). A protrusion does not exceed the cranio-caudal boundaries of the intervertebral disc. On the axial image the disc herniation looks like a disc protrusion (the base of the herniation appears wider than the tip). However, when you view the same herniation from the sagittal orientation, you can see a narrowed waist of the disc at the point that it exits the intervertebral space, and the disc expands out. A disc extrusion is present when an expansion is visualized in either the axial or sagittal views or if a sequestered fragment is present. This sagittal image of the same protrusion (green arrow) as its base is wider herniation in figure 5:29 shows a narrowed than its tip. Sequestered disc fragments have broken off and are no longer contiguous with the rest of the disc. A sequestered fragment is the designation given to a disc derangement in which a portion of the disc breaks free from the rest of the disc. A large sequestered disc fragment in the central canal of L5 displacing and compressing the S1 nerve root. The red dotted line outlines the sequestered disc fragment, and the blue line outlines the S1 nerve root. This image contains a sequestered disc fragment that displaces and compresses the left S1 nerve root. Note the degree of swelling of the displaced left nerve root in comparison to the right nerve root. If the disc has violated the outer annulus, it is categorized as a non contained herniation. If the disc derangement disrupts and passes through the posterior ligaments, it has been called an extra-ligamentous herniation. An extra-ligamentous herniation does not violate the integrity herniation violates the integrity of the of the ligaments, usually the posterior posterior longitudinal ligament. Axial schematic image of a paracentral disc herniation displacing an S1 nerve root. Axial image of a paracentral disc herniation (green arrow) that contacts and displaces the left S1 nerve root. Anterior disc herniations do not compromise the spinal cord, thecal sac, or nerve roots, but may be a source of pain and indicative of biomechanical failure. Even a small herniation in the foraminal canal can cause significant nerve impingement. Axial image of a far lateral herniation shown outlined with a red dotted herniation. Far lateral herniations may contact and affect the exiting nerve root after it leaves the intervertebral foramen. The image on the right outlines the circumference of this far lateral herniation which is visualized in both images. These are the volume descriptors for the amount of disc material herniated into the central canal as observed on the axial image at the slice of most severe compromise. A canal compromised less than one-third is a mild herniation (figure 5:52), between one-third and two-thirds is considered a moderate herniation (figure 5:53), and over two-thirds is a severe herniation (figure 5: 54).

Clinical imaging: with skeletal, chest and abdomen pattern differentials(third edition). Annular tears may occur from trauma or over time as part of a degenerative process. Some experts prefer the term annular fissure since it is less implicative of trauma. There are three categorizations of annular tears: radial tears, transverse tears, and concentric tears. Annular tears may be clinically significant or may be asymptomatic coincidental findings. Radial Tears Radial tears begin centrally and progress outward in a radial direction. Radial tears may precede the migration of the nucleus, resulting in a disc herniation. Radial tears of the disc radiate out in a radial direction from the center of the disc. Radial Tears these two T2 sagittal images demonstrate radial tears of the annulus of the disc between L5 and the sacrum. Transverse tears are horizontal lesions that may involve the disc tearing away from the endplate. This lesion may involve disruption of Sharpeys fibers (the matrix of connective tissue that binds the disc to the vertebral endplates) and the disc. Transverse tears appear to have a causal effect in degenerative disc disease and the formation of osteophytic spurring. They are typically small and limited to the joining of the annular attachments to the apophyseal ringthe rim of the vertebra, hence the term rim lesion. The two images above show a transverse annular tear from the superior endplate at the posterior margin of the sacrum. Below is an image from a different patient with a small tearing of the annulus fibers from the superior apophyseal ring of the sacrum. Annular tears are well demonstrated in T2 images and appear as high-intensity zones, thus appearing white in T2 weighted images. Incidentally, it is the outer third of the annular fibers that are the most richly innervated and vulnerable to nociception. They are characterized by high intensity zones (white appearance) on T2 weighted images. The T2W images above are from the same patient and show a transverse concentric tear involving the posterior portion of the L5-S1 disc.

Clinical imaging: with skeletal, chest and abdomen pattern differentials(third edition). As you view this pictorial essay take a moment to consider the components of each disc herniation: the vertebral level, the anatomical zone, and the type of derangement (tear, extrusion, protrusion, bulge, intravertebral herniation, and so forth). In addition to identifying the nomenclature and classification of the disc lesions, take time to familiarize yourself with the other structures in each image. Of particular interest to clinicians is the disc injurys relationship to the cord, the cauda equina, thecal sac, and nerve roots. Moreover, consider the impact of disc derangement on facets, muscles, ligaments, endplates, vertebral bodies, the canal space, epidural venous plexus, sacroiliac joints, and other anatomical structures. A disc herniation may be associated with facet effusion, multifidus atrophy, bony edema of the vertebral bodies, facetal imbrication, ligamentum flavum changes, posterior longitudinal ligament disruption, and other anatomical and functional failures. Additionally, take time to consider the potential clinical consequences of particular disc injures: pain distribution, orthopedic-neurologic signs, and effects on other anatomical structures. By viewing a variety of different derangements, you will begin to gain familiarity of this topic and be more competent at discerning the nuances of disc disease. T1 images have good anatomical detail, but contrast is reduced between the disc and the cerebral spinal fluid in the thecal sac, making it more difficult to identify a disc herniation. Most of the disc herniations in this chapter will be presented in T2 weighted format. This T2 weighted sagittal a round circumscribed herniation (sequestered image shows a light-colored sequestered disc fragment) descending into the sacral canal disc fragment descending into the sacral and displacing the thecal sac and the S1 nerve canal along the body of S1. These four images show a large L5-S1 sequestered extrusion that extends caudally into the central canal of the sacrum following the left S1 nerve root and displacing the thecal sac. This T2 weighted axial image reveals a right foraminal herniation of the L4-5 disc. This sagittal T2 weighted image reveals a right foraminal herniation of the L4-5 these images reveal a foraminal herniation at disc. These images show the regression of a large extrusion of the L4-5 disc over a six month period of conservative care. Endplate disruption and bony edema of the vertebral bodies will be discussed more fully in Chapter 12. From an axial perspective figure 7:18 reveals the extent this disc extrusion occupied the central canal, subarticular zone, and foraminal zone. Figure 7:19, taken six months later, clearly demonstrates a profound reduction in the size of the herniation. This sequence of images show a sequestered extrusion of the L5-S1 disc extending inferiorly into the central canal of the sacrum (figure 7:20). Two months after surgery, he re-herniated the L5-S1 disc, this time with superior migration of the extruded disc along the posterior body of L5 (figure 7:21). He was treated conservatively with chiropractic care, exercise, and modified work postures. The herniation still extends superiorly along L5, but the mass of the herniation is significantly reduced. This T2W axial image of the same patient reveals a focal herniation arising from a broad-based herniation. These images reveal a focal extrusion on top of a broad-based protrusion of the L5-S1 disc. The focal extrusion between the S1 nerve roots contacts both descending S1 nerve roots and effaces the thecal sac. This T2 weighted axial image reveals a posterior concentric annular tear reveals broad-based herniation with a of the L4-5 disc. This sagittal image displays image reveals a transverse annular tear a posterior transverse tear at the superior of the anterior of L2-3 on the superior endplate of L4 (yellow arrow), a L3 endplate. There is also a tear along concentric tear of the posterior L5 disc the superior endplate of L4 affecting the (green arrow), and a small portion of a posterior portion of that disc. T2W axial image showing a left para revealing desiccation of the L4-5 and central extrusion of the L5-S1 disc. These T2 weighted images reveal an L5-S1 paracentral disc extrusion displacing and compressing the left S1 nerve root.

If portable incubators are used antibiotics for acne doxycycline order flagyl master card, it is important to make sure that such incubators can accurately stabilize the temperature at 37 C infection elbow proven flagyl 400 mg. Laboratories should avoid manual entry of results to avoid additional variability and errors (see Appendix D) bacteria on the tongue cheap flagyl 250mg mastercard.

Thus antimicrobial dressings for wounds buy flagyl 250mg cheap, further research is needed to identify biomarkers that are highly predictive and can identify 69 latently infected individuals who are at highest risk of disease progression. However, low-risk individuals are commonly tested before exposure, when repeat testing is likely. Only those who would benefit from treatment should be tested, so a decision to test presupposes a decision to treat if the test is positive. This strategy will improve the overall specificity of the testing process in low-risk individuals and may also be cost-effective, as shown in a Canadian 71 study. If results do fall in this zone, care providers could choose to repeat the test, depending on the clinical context and other information available (e.

Prevent the relapse of disease after completion of therapy and achieve long-lasting cure. In the initial phase multiple effective drugs are used in combination to achieve the first and second objective. On the basis of results of randomized trials, this phase should last 2 months, and the drugs should preferably be given daily. The second objective is addressed by the continuation phase, during which only two drugs are usually given. The length of this phase is variable, depending on indicators of risk of relapse, on the drugs given in the initial phase and on the results of pre-treatment drug susceptibility testing. Optimal therapy to achieve all three treatment objectives for patients of all ages, with disease at any site, should be guided by the results of drug susceptibility testing. If drug suscepti bility testing results are pending then more drugs may be needed to ensure that at least two are likely to be effective. In the initial intensive phase, particularly when bacillary load is high (see below), three likely effecttive drugs should be used to prevent emergence of drug resistance. Therefore, it is recommended that all necessary measures be taken to avoid patient drop-out or loss to follow-up, or interruption of drug supply. If patients experience adverse events, an alternative therapy should be initiated promptly. Practitioners who cannot guarantee adequate monitoring and supervision of therapy should refer the patients immediately to centres where this can be assured. However, to understand the rationale for many of the principles above it is useful to understand how drug resistance develops. Therapy with a single drug will lead to the uninhibited growth of bacilli carrying the mutation to this drug while all 9 other bacilli are eradicated. This means that within 2-3 months of the start of monotherapy all 10 bacteria will carry this mutation, and clinically the patient will be fully resistant to that drug. Fortunately, the mutations to different drugs are independent, so treatment with two drugs will usually mean that the mutants with resistance to one drug are killed by the other drug, unless the 9 total number of bacilli is very high. Using this, and the spontaneous mutation rate, it is possible to calculate the probability that treatment with one, two or three drugs will lead to the emergence of drug resistance as a result of natural or spontaneous mutations, even in a patient who takes all doses properly. Evidence about the action and the role in therapy of each drug comes from in-vitro and animal studies as well as from multiple randomized trials. It is clear that eye toxicity is dose dependent, and its risk is higher at 25 mg/kg than at 15 mg/kg. If these drugs are needed because of intolerance or resistance to first-line drugs, daily therapy is suggested **Initial dosage if renal function is normal. Dosing should be adjusted based on peak and trough serum levels in consultation with a pharmacist. It has very powerful early bactericidal activity, meaning that it is highly effective in rapid killing of bacteria in the first few days. It is also effective in preventing the emergence of resistance, although its role in preventing relapse is unclear. Pyridoxine (vitamin B6) should routinely be added for patients with diabetes, renal failure, malnutrition, substance abuse or seizure disorders or for women who are pregnant or breastfeeding, because of the increased risk of symptoms related to pyridoxine deficiency in these patients. The drug has good bactericidal activity (Objective 1), prevents acquired drug resistance (Objective 2) and is very important in preventing relapse (Objective 3). Current doses are based on studies performed in the 1960s, when the lowest effective dose was used because of the high cost of the drug. When the results are available, recommendations for use of the drugs as first-line therapy may change. Injectables the injectables include streptomycin, amikacin, kanamycin and capreomycin. On the basis of expert opinion, the Canadian Thoracic Society suggests that of all the injectables amikacin is preferred for use in Canada, because it is available in most hospitals, providers (including pharmacists) are familiar with the drug, and drug concentrations are readily available, reducing risk of toxicity. There are few situations in which one can confidently predict such a low likelihood of any resistance, especially since the prevalence of resistance has risen steadily over the last 40 years in all populations with access to treatment. If patients miss a single dose while receiving thrice weekly therapy they effectively receive twice weekly therapy, which is still adequate. If they miss a dose of twice weekly therapy they effectively receive once weekly therapy which is inadequate. The tablets can be crushed and mixed with water, or suspensions of the medications can be prepared to make delivery easier. To prolong therapy in all patients in order to achieve a 3% reduction in relapse would expose many patients needlessly to prolonged therapy. These include having more extensive disease and/or 19 cavities on a chest x-ray in the first 2 months of therapy, being culture-positive after 2 months of 19 20 therapy or having a cavity on chest x-ray at the end of treatment. Many studies have evaluated different schedules of therapy in the continuation phase, after daily therapy for the first 2 months. If a patient receiving thrice weekly intermittent therapy misses a single dose they are effectively receiving twice weekly therapy, which is still acceptable. In theory these formulations should prevent monotherapy from physician or patient error, or patient selection of only some of their medication. If the risk of non-adherence is judged to be low, the lower risk of toxicity may justify the longer therapy. It is suggested that all drugs can be given in normal doses and frequency, but with careful monitoring for toxicity. It is preferable to reduce the frequency of administration of these drugs rather than reduce the doses, as the peak serum concen-trations are key to their bactericidal effects. Monitoring serum concentrations will be very useful to ensure that adequate, yet safe, doses are given. The use of injectables (streptomycin, amikacin, kanamycin and capreomycin) should be avoided if possible in patients with impaired renal function, as these drugs are excreted by the kidney and may cause 1,6 worsening renal function as well as other toxicities. Hence, the standard dosing and schedule are recommended, but patients should be closely monitored, and therapeutic drug monitoring. To date there have been no reports of teratogenicity even though this drug has been given to millions of pregnant women worldwide. The use of injectables (streptomycin, amikacin, kanamycin and capreomycin) is contraindicated because of the effects on the fetus, including eighth cranial nerve palsies, 4 deafness and teratogenic effects. The resulting amounts ingested by the newborn baby will not produce toxic effects. It is important to remember that the amount ingested in maternal milk would not constitute an effective dose for treatment or prophylaxis in a nursing 27 infant, even in a newborn. Most of these drug interactions can be managed by adjusting the dosage according to measured drug concentrations (e. In some patients the drug interactions are not manageable or could result in serious consequences, such as a patient receiving immune suppressive therapy following solid organ transplantation. Two reviews suggest that prednisone in doses of 40-80 mg/day for 6-12 weeks 31,32 is likely to be effective, but the optimal dose and duration of treatment are not well defined. In a meta-analysis of three small randomized trials of patients with tuberculous pleurisy, corticosteroids resulted in more rapid resolution of symptoms and pleural 33 fluid, but there was no evidence of long-term benefits. Chest radiography should be performed after 2 and 6 months of therapy to assess response, potential complications and risk of relapse. This is best done by providing a 34 comprehensive, patient-centred treatment program. Key elements include use of incentives and enablers, nursing care, coordinating care for other medical problems, social service support such as for child care, housing assistance, referral for treatment of substance abuse and providing transportation where possible. For patients receiving self administered therapy this would also include monitoring and reinforcement of adherence through measures such as detailed inquiry, reinforcement of prompts to take the medications at every follow-up visit, use of tick-off calendars, linking medication taking to a specific event in the daily routine, routine pill counts or daily cell phone text reminders. In many jurisdictions the public health department can and does play an important role in monitoring and enhancing adherence to treatment. Many studies, including randomized trials, cohort and ecologic studies, have examined this question. However, confounding and other sources of bias were major limitations of these observational studies. Hence, the generalizability of these results to Canadian settings may be questioned, particularly with respect to children or adolescents. Individual risk factors: disease due to multidrug-resistant organisms; treatment failure or documented relapsed disease; injection drug use/other substance abuse; homelessness or unstable housing; suspected non-adherence or previous non-adherence; major mental illnesses; and children and adolescents. This is defined as a benchmark of 5% or more of patients who had outcomes of default, lost to follow-up, transfer out without known outcomes or were otherwise not accounted for. Serum samples must be sent to the Florida Infectious Disease Pharmacokinetics Laboratory idpl. Information about the timing of blood draws, processing and shipping of samples is available from the websites of the two laboratories offering this service. A systematic review of 66 studies of therapeutic drug monitoring, which involved 2,938 patients, has recently been completed.

When the bag is full infection knee replacement symptoms buy flagyl master card, pressure rises and nerves send a message via the spinal cord to the brain antibiotic poisoning cheap flagyl 250 mg. When one is ready to empty the bladder bacterial colony generic flagyl 400mg on line, the brain sends a message back down the spinal cord to the bladder antibiotic side effects purchase flagyl 250mg with amex, telling the detrusor muscle (the bladder wall) to squeeze and the sphincter muscle (a valve around the top of the urethra) to relax and open antimicrobial dressing generic flagyl 400mg on-line. Paralysis Resource Guide | 84 2 After paralysis antibiotic resistance nice discount flagyl master card, however, the bodys normal system of control goes haywire; messages can no longer pass between the bladder muscles and the brain. Both the detrusor and the sphincter may be overactive due to lack of brain control. An overactive detrusor can contract at small volumes against an overactive sphincter; this leads to high bladder pressures, incontinence, incomplete emptying, and reflux along with recurrent bladder infections, stones, hydronephrosis (kidney distention), pyelonephritis (kidney inflammation), and renal failure. Spastic (refex) bladder: when the bladder fills with urine, an unpredictable reflex automatically triggers it to empty; this usually occurs when the injury is above the T12 level. Physicians familiar with spinal cord injury often recom mend a bladder relaxing medication (anticholinergic) for reflexive bladder; oxybutynin (Ditropan) is common, with a primary side effect of dry mouth. The advantage: Botox is used focally in the bladder, thus avoiding systemic side effects, including dry mouth. Flaccid (non-refex) bladder: the reflexes of the bladder muscles are slug gish or absent; it can become over-distended, or stretched. Treatments may include sphincter relaxing medications (alpha-adrenergic blockers) such as terazosin (Hytrin) or tamsulosin (Flomax). Bladder outlet surgery, or sphinc terotomy, reduces pressure on the sphincter and thus allows urine to flow out of the bladder easier. An alternative to sphincterotomy is placement of a metal device called a stent through the external sphincter, thus ensuring an open passage. One drawback to both sphincterotomy and stenting is that sperm from an ejaculation ends up in the bladder (retrograde), rather than coming out the penis. This doesnt rule out having a child but complicates it; sperm can be collected from the bladder but can be damaged by urine. Dyssynergia occurs when the sphincter muscles do not relax when the bladder contracts. The urine cannot flow through the urethra, which can result in the urine backing up into the kidneys (called reflux), which can lead to serious complications. If drainage originates from a stoma (a surgically created opening) at the pubic bone area, bypassing the urethra, its called a suprapubic catheter. Disadvantage: besides the need for a collection device, indwelling catheters are more prone to urinary tract infection. An external condom catheter, which also drains continuously, is an option for men. No longer is it necessary to reuse a catheter over and over again, rinsing it out after 30 or 40 uses. It makes perfect sense that disposable caths might reduce the incidence of bladder infection, especially the closed no touch systems with a tip that remains sterile. Still, Medicare is not so compelled as to pay for sterile catheters, at least not until a person gets really sick from a bladder infection twice and then gets a doctors prescription. A regular catheter is enormously cheaper (less than $200 a month versus $1500 a month or more for disposable sterile caths). Another type of premium catheter on the market features a super slippery hydrophilic coating to allow easier insertion. LoFric is a well-known brand; most major urological companies have a hydrophilic line now. You can get these paid for, too, once you prove your urethral openings are at risk. Bladder augmentation is a procedure that surgically enlarges the bladder, using tissue from the intestines, to expand bladder capacity and thus reduce leaking and the need for frequent catheterization. As for cranberries and bladder health, well, a lot of folks swear by the juice or dried fruit, a lot of people say forget about them; there are published reports in support of both sides. The National Center for Complimentary and Alternative Medicine leans toward the pro-cranberry side, and suggests that cranberries limit the ability of e-coli bacteria to stick to the wall of the bladder. Of course the berry and supplements industries lead the cheers, and a paper a few years back from Scotland noted some evidence that cranberry juice may decrease the number of symptomatic bladder infections over a 12 month period in women. More recently, a group at the Kessler Institute in New Jersey suggested that cranberry supplements have no efect in preventing urinary tract infections. It is common for people with multiple sclerosis and other spinal cord diseases to have problems with bladder control. This can involve a little leaking after a sneeze or laugh, or loss of all control. For many people, appropriate clothing and padding can compensate for lack of control. Some women benefit from strength ening the pelvic diaphragm (Kegel exercises) to improve retention of urine. The source of infection is bacteria, a group or colony of tiny, microscopic, single-celled life forms that live in the body and are capable of causing disease. Also, many people are not able to completely empty their bladder; bacteria are more likely to grow in urine that stays in the bladder. One may also feel burning while urinating, and/or discomfort in the lower pelvic area, abdomen or lower back. Once symptomatic, the first line of treatment is antibiotics, including the fluo roquinolones (e. Meticulous hygiene and proper handling of urinary care supplies can help prevent infection. This can make it harder for your urine to drain and can make it easier for bacteria to spread. Drinking the proper amount of fluids can help with bladder health, by washing bacteria and other waste materials from the bladder. According to some research studies, cranberry juice, or cranberry extract in pill form, can be an effective preventative for bladder infections. It works by making it hard for bacteria to stick to the wall of the bladder and colonize. Another way to keep the bacteria from colonizing on the bladder wall is the use of D-mannose, a type of sugar available at health food stores. This should include a urologic exam, including a renal scan or ultrasound to know that the kidneys are working properly. Research shows a moderate increase in the risk of bladder cancer among those who have been using indwelling catheters for a long period of time. The bowel, the final portion of the tract, is where the waste products of digested food are stored until they are emptied from the body in the form of stool, or feces. After food is swallowed, it moves through the esophagus to the stomach, which is basically a storage bag, and then on to the intestines or bowels. The absorption of nutrients occurs in the small intestines, the duodenum, the jejunum and the ileum. Next is the colon, which encircles the abdomen, starting on the right with the ascending colon, passing across the top with the transverse colon, and down the s-shaped sigmoid colon to the rectum, which opens at the anus. Feces move through the bowel by coordinated muscular contractions of the colon walls called peristalsis. The myenteric plexus nerves direct local intes tinal movement, seemingly without input from the brain or spinal cord. More than 100 years ago it was discovered that the intestines, even when removed from the body, have an inherent tendency to produce peristalsis. If the intestine wall is stretched, the myenteric plexus triggers the muscles above the stretch to constrict and those below to relax, propelling material down the tube. Conscious perception of a full rectum permits discrimination between solid material and gas, and the decision to eliminate fecal matter when appropriate. Messages relayed via the spinal cord produce voluntary relaxation of the pelvic floor and anal sphincter muscles, allowing the defecation process to occur. The result is constipation and a higher risk of incon Paralysis Resource Guide | 90 2 tinence due to lack of a functional anal sphincter. To minimize formation of hemorrhoids, use stool softeners, minimal straining during bowel efforts, and minimal physical trauma during stimulation. The best way to prevent them is to follow a schedule; to teach the bowel when to have a movement. Most people perform their bowel program at a time of day that fits with their lifestyle. The program usually begins with insertion of either a suppository or a mini-enema, followed by a waiting period of approximately 1520 minutes to allow the stimulant to work. After the waiting period, digital stimulation is performed every 1015 minutes until the rectum is empty. Those with a flaccid bowel frequently start their programs with digital stimulation or manual removal. But those at high risk for skin breakdown need to weigh the value of bowel care in a seated position, versus a side-lying position in bed. Anything that changes the speed with which foods move through the large intestine interferes with the absorption of water and causes prob lems. Laxatives such as Metamucil supply the fiber necessary to add bulk, which holds water and makes it easier to move stool through the bowels. Stool softeners, such as Colace, also keep the water content of the stool higher, which keeps it softer and thus easier to move. Stimulants such as bisacodyl increase the muscle contractions (peristalsis) of the bowel, which moves the stool along. Frequent use of stimulants can actually aggravate constipation the bowels become dependent on them for even normal peristalsis. There are two main types of suppositories, both based on the active ingredient bisacodyl: those with a vegetable base (e. Antegrade continence enema is an option for some people with difficult bowel problems. This technique involves surgery to create a stoma, or opening, in the abdomen; this allows introduction of liquid above the rectum, thus causing an effective flushing of fecal material from the bowel. Here are some bowel facts for better digestive management: It is generally not necessary to have a bowel movement every day. For example, anticholinergic medications (for bladder care) may slow bowel motility, resulting in constipation or even bowel obstruction. Some antidepressant drugs, such as amitriptyline; narcotic pain medications; and some drugs used for the treatment of spasticity, such as dantrolene sodium, contribute to constipation. This surgical option creates a permanent opening between the colon and the surface of the abdomen to which a stool collection bag is attached. Colosto mies sometimes become necessary because of fecal soiling or pressure sores, continual stool incontinence, or excessively long bowel programs. Colostomy enables many people to manage their bowels independently, plus, colostomy takes less time than bowel programs. Studies have shown that people who get colostomies are pleased and would not reverse the procedure; while many may not have embraced the idea of a colostomy at the outset, the procedure can make a huge difference in quality of life, cutting bowel time from as much as eight hours a day to no more than 15 minutes. Deep vein thrombosis is a blood clot that forms in a vein deep in the body, most often in the lower leg or thigh. This can result in a life-threatening danger if the clot breaks loose from the leg vein and finds its way to the lung, causing a pulmonary embolism. Doctors use anticoagulants, commonly called blood thinners, to prevent blood clots. In spinal cord injury, anticoagulants are generally given with the first 72 hours after injury to all patients. These medications slow the time it takes for blood to clot and also prevent growth of a clot. Routine use of graduated compression stockings is common in people with paralysis. Paralyzed Veterans of America, in support of the Consortium for Spinal Cord Medicine, offers (no charge) an authoritative clinical practice guideline for deep vein thrombosis. It involves major changes in mood, outlook, ambition, problem solving, activity level and bodily processes (sleep, energy and appetite). It affects health and wellness: People with a disability who are depressed may not look after themselves; they may not drink enough water, take care of their skin, or manage their diet. In spinal cord injury, for example, risk is highest in the first five years after the injury. Other risk factors include dependence on alcohol or drugs, lack of a spouse or close support network, acess to lethal means, or a previous suicide attempt. The most important factors in preventing suicide are spotting depression early, getting the right treat ments for it, and instilling problem solving skills. These may include the effects of disability pain, fatigue, changes Mental Health America in body image, shame, and loss of ofers these tips to reduce independence. Other life events, such depression: as divorce, loss of a loved one, loss of a job or financial problems can also Stay connected lead to or magnify depression. Depression is highly treat Get enough sleep able using psychotherapy, pharma Create joy and satisfaction cotherapy (antidepressants), or a Eat well combination of both. In theory, it may also alleviate some forms of neurogenic pain, a huge contributor to depression. In fact, aggressive treatment of pain problems is crucial to the prevention of depression. About 80 percent of people with multiple sclerosis report that fatigue significantly interferes with their ability to function.

The differentiation of these patients from cases of real attention-deficit-hyperactivity disorder is that they have some of the positive attributes of the hyperthymic temperament such as confidence, caring for others, cheerful moods, interpersonal charm. When hyperthymic individuals become depressed, usually the init ial episode is hypersomnic-retarded. The use of antidepressants tends to destabilize, it would seem, the underlying hyperthymic temperament. These are depres sive mixed states (Akiskal and Mallya 1987) which can be quite protracted 56 H. Koukopoulos and colleagues (1992) have elsewhere described these patients as "excited depressives". We have not considered the severe psychotic end of bipolar disorder (Akiskal and Puzantian 1979), nor have we presented the emerging fascinating data about the offspring of bipolar parents (Akiskal et al. In practice this means that, when confronted with a clinically depressed patient, one must not undertake treatment before a careful family history for bipolarity. There are "atypical" seasonal depressions without discernible hypo manic states, but activation in the spring. Related to these forms are periodic depressions with abrupt onset and offset; bipolar family history is often detected during systematic evaluation of such cases. Other patients may present with episodic obsessivecompulsive symptomatology, periodic states of irritability, and/or acute suicidal crises in the absence of a clear cut affective symptomatology. Then there are patients with episodic neuras thenic or sleep complaints, or those with severe brief depression. We have the soft bipolar spectrumh 57 elected to hold back definitive judgement on whether they too belong to the bipolar spectrum. The foregoing conditions require further study before the link to bipolarity is validated. The main emphasis of this chapter has been on the clinical phenomenol ogy of bipolar subtypes. But in a disorder that has remissions and exacerbations it is not possible to divorce the clinical picture from treatments received. We are aware that many distinguished scientists and practitioners might disagree with the latter position. In partic ular, aggravation of the course of bipolar disorder by antidepressants is considered controversial in the scientific literature (see, for instance, Lewis and Winokur 1982, Angst 1985, Kupfer 1988). In our opinion this contro versy is largely based on a literature which has studied patients who are not representative of the larger universe of patients seen in contemporary clinical practice. Our ongoing collaboration (Akiskal and Pinto 1999) addresses the challenge of making sense of patients who do not become research subjects. We have presented research data, as well as illustrative clinical case material, which supports their inclusion in a broad bipolar spectrum. Ultimately, molecular genetic strategies might help in a more natural classificatory schema. The subclassification we have developed is not the final word on the bipolar spectrum: we offer it as a tool to facilitate genetic, clinical, and therapeutic research. As practising clinicians in a specialized university mood centre, we are overwhelmed with the number of patients who are destabilized by extensive 58 H. It is vital to recognize their soft bipolar tendencies prior to this complication. This decade has seen the development of many anticonvulsant mood stabilizers, which have been enormously helpful in minimizing or preventing such destabilization. The phenomenon of increased cycling in bipolar disorder was not as commonly observed in the 1950s, 1960s, and 1970s (Akiskal and Puzantian 1979, Angst 1985, Wolpert et al. Given the spectre of tardive dyskinesia, the use of classical neuroleptics in bipolar disorder has been viewed as problematic, though it is widely used in clinical practice (Sernyak et al. In our experience the short-term use of small doses of such agents as thioridazine (25100 mg) is often helpful in bringing rapid control to the insomnia, excitement, impulsivity, and risk-taking behaviour often observed in the entire spectrum of bipolar disorders (Akiskal 1999a). With the advent of atypical neuroleptics which seldom give rise to extra pyramidal side-effects we have been more lately using them in moderation and in low doses in those soft bipolar patients in whom rapid control of risk taking was necessary to prevent tragic consequences, or in situations where anticonvulsant mood stabilizers failed to bring appreciable clinical results. We have even observed that in selected cases an atypical neuroleptic such as olanzapine (2. Obviously, a great deal of systematic research needs to be conducted in further clarifying the role of both anticonvulsant mood stabilizers and atypical neuroleptics in the bipolar spectrum. We wished to close this chapter with a therapeutic note in order to emphasize that, beyond its use in helping classification and research, the ultimate purpose of any revision in our diagnostic system is to improve the way we clinically manage the patient. In this context it is also important to emphasize the vital role of a specialized mood or bipolar clinic in the overall management of these patients. For many of these patients their periodic visit to such a clinic and their physician or therapist, represents the only, or the main, stable human contact during extended troubled phases of their life. By the same token, such a clinic is the optimum setting in which the tempestuous spectrum of disorders described in this chapter can be properly studied.

In his 1921 treatise Manic-Depressive Insanity Kraepelin stated that "very often we meet temporarily with states which do not exactly correspond either to manic excitement or to depression, but repre sent a mixture of morbid symptoms of both forms of manic-depressive insanity" (p. He called such co-occurrences of manic and depressive symptoms mixed states and defined them broadly, in that a patient needed to exhibit only one of three abnormal components of mood states (manic or depressive mood, thought, and behaviour) in a polarity opposite to the other two to qualify for a mixed-state diagnosis. He thus specified six types of mixed states, based on various combinations of manic and depressive mood, thought, and behaviour. These were: (1) depressive or anxious mania, (2) excited depression, (3) mania with poverty of thought, (4) manic stupor, (5) depression with flight of ideas, and (6) inhibited mania. Although authorities since Kraepelin have continued to stress the impor tance of mixed states in understanding the fundamental nature of bipolar disorder (Akiskal et al. All three systems exclude patients with a variety of subsyndromal mixed states mania with subsyndromal depressive symptoms, major depression with hypomanic symptoms, and various combinations of hypomanic and dys thymic symptoms. Fortunately, increased empirical attention has recently been given to mixed states, especially over the past 10 years. In this chapter, we review the literature on the phenomenology, epidemiology, course and outcome, biology, and treatment response of mixed states, with emphasis on recent studies. For example, he described "depressive or anxious mania" as "a morbid state composed of flight of ideas, excitement, and anxietymood is anxiously despairing". He characterized "excited depression" as "extraordinary poverty of thought but, on the other hand, great restlessness mood is anxious, despondent, lachrymose, irrita ble, occasionally mixed with a certain self-irony". In his 1953 book Manic-Depressive Disease: Clinical and Psychiatric Significance, Campbell wrote: "The mixed type of manic-depressive psychosis epitomizes the entire cyclothymic process, in that it contains the symptoms characteristic of the various phases. Whether it is a sustained reaction or represents a phase of metamorphosis between the major forms, the mixed type emphasizes the underlying similarities between the depressive and hypomanic, the fact that the manic and depressive reactions may be superimposed, and that the same individual possesses the potentialities for either form". The mixed bipolar disorders 65 Campbell also observed: "There is nothing static about this autonomicemotionalpsychic disturbance; it is a dynamic and ever-changing process, with innumerable degrees of depression as well as mania. It is not mania and depression, or two distinct forms, but manic depressive, a continuous process involving essentially a dysfunction in the emotional sphere. Indeed, there are more mixed reactions of this disease than is generally realized. Many modern authorities have also provided excellent descriptions of bipolar mixed states. Patients have been described as displaying varied combinations of a wide range of mood, neurovegetative, cognitive, and behavioural symptoms, particularly variability or lability in mood and psychomotor activity, and a "pleomorphic" presentation with "innumera ble" combinations "of often contrasting symptoms" (McElroy et al. For example, in stressing the phenomenological complexity of mixed epi sodes, Himmelhoch (1979) remarked that they are "chameleon-like in their presentation, appearing in some patients like schizophrenia, in others like psychotic depression and in still others like labile, hysteroid states, thereby creating a set of difficult diagnostic conundrums for the clinician". More recently, several groups have begun to systematically investigate the phenomenology of mixed states using modern empirical methodologies (Akiskal et al. These studies (which are described below) are confirming earlier reports that depressive signs and symptoms are common in mania and hypomania, that manic features occur in depres sion, and that mixed states should be conceptualized and defined broadly and dimensionally, as well as categorically, and not narrowly. The authors found that depressive symptoms were continu ously rather than bimodally distributed and did not support a clear dichoto mous distinction between dysphoric and non-dysphoric hypomania or mania. They concluded that dimensional as well as categorical approaches were needed to distinguish dysphoric from non-dysphoric states. However, when mixed mania was defined more broadly, differences in sex distribution and hospitaliza tion duration were lost. It was concluded that dimensional rather than categorical systems to describe the degree of associated depression might be a more meaningful method of classifying mania. The authors concluded that the presence of two or more depressive symptoms was a clinically meaningful way to define mixed mania. Dysphoric mood, mood lability, anxiety, guilt, suici dality, and irritability were the only symptoms significantly more common in the mixed group, whereas grandiosity, euphoric mood and pressured speech were significantly more common in the manic,group. They identified five independent factors representing psychomotor pressure, psychosis, increased hedonic function, irritable aggression, and dysphoric mood. The dysphoric mood factor included positive ratings of depressed mood, anxiety, guilt, mood lability, and suicide, and a negative rating of euphoric mood. The authors concluded that the bimodal distribution of the dysphoric mood factor was consistent with the possibility that mixed bipolar disorder was a distinct state. The analysis revealed four factors corresponding to manic activation, depressed state, sleep disturbance, and irritability/paranoia. Cluster analysis separated the patients into two groups, which differed only with respect to depressed mood. Further analy sis, however, suggested three groups of manic patients differing regarding the severity of associated depressive symptoms: mania with minimal depressive symptoms, mania with full superimposed major depression, and mania with depressive symptoms intermediate between the other two. In summary, numerous modern phenomenology studies, including factor-analytic studies, have confirmed the occurrence of depressive symp toms in mania, and have provided support for the hypothesis that mixed mania (mania with depressive features) may be distinct from pure or euphoric mania (mania without depressive features). Moreover, these studies suggest that systems used to define mixed states should be broad and dimensional as well as categorical, rather than overly narrow. Akiskal Goodwin and Jamison (1990) wrote, "in general, it is best to consider the depressive spectrum and the manic spectrum as independent and capable of interacting in a variety of combinations and permutations". Patients can have various combinations of various degrees (none, mild, moderate, severe) of manic and depressive symptoms, thereby allowing more accurate diagnosis and, hence, more appropriate treatment. These observations repeatedly suggest that mixed bipolar states can present as full syndromal depression with subsyn dromal mania, and that modern diagnostic systems should be modified to reflect this. As noted, Kraepelin (1921) described the mood of both depressive or anxious mania and excited depression as often having an anxious component. More recently, factor-analytic studies of the signs and symptoms of mania have found that anxiety loads with depressed mood in mania (Cassidy et al. Kraepelin (1921) noted "the frequent contra diction between the content of the delusions and the colouring of mood. A patient told me with laughing that his nerves were dried up and his blood circulated only as far as his neck.
