Walker Preface Pathogenic microorganisms and their toxins have always posed a significant threat to humans, animals, and plants that become exposed and infected naturally. But now there is a newly recognized threat the deliberate use of pathogenic microorganisms and toxins as weapons in acts of bioterrorism or in the commission of biocrimes. Long before the germ theory of disease was understood, man knew that pathogenic microorganisms and toxins were useful as weapons. However, as the twentieth century came to a close, the perceived difficulties in production, weaponization, and deployment of these biological weapons as well as a belief that moral restraints would preclude the use of these weapons gave many a false sense of security. Recently, a number of events have served to focus attention on the threat of terrorism and the potential for the use of biological weapons against the military, civilian populations, or agriculture for the purpose of causing illness, death, or economic loss. This threat is a significant concern in the United States as well as internationally. In either scenario, biologic agents could be introduced into populations by several routes, including aerosol; contamination of food, water, or medical products; fomites; or the release of infected arthropod vectors. The deliberate nature of such dissemination will often be obvious, as in the case of multiple mailed letters containing anthrax spores (ie overt). Because we currently lack the ability to conduct extensive real-time monitoring for the release of a biologic agent, a covert release of a microorganism of toxin in a population would be likely to go unnoticed for some time, with individuals exposed leaving the attack area before the act of terrorism became evident. Because of the incubation period, the first signs that a microorganism or toxin has been released may not become apparent until hours or weeks later, when individuals become ill and seek medical care. Bioterrorism presents many challenges, particularly when compared to chemical, radiological, or nuclear terrorism. These challenges reflect the dual-use nature of many technologies that can be used for either beneficial purposes or bioterrorism; intentional threats that can coexist with similar and naturally occurring threats; the complexity of the interaction of the threat with the environment, the human immune system, the society/social structure; and rapid advances in biotechnology. Many biological agents can cause illness in humans, but not all are capable of affecting public health and medical infrastructures on a large scale. The final category assignments (A, B, or C) of agents for public health preparedness were based on an overall evaluation of the ratings the agents received in the aforementioned criteria. Agents placed in Category A (eg Yersinia pestis, botulinum neurotoxins) were considered to have a moderate to high potential for large-scale dissemination, the greatest potential for adverse public health impact with mass casualties, and a requirement for broadbased public health preparedness efforts. Agents placed in Category B (eg rickettsia, ricin, staphylococcal enterotoxins) also have some potential for large-scale dissemination with resultant illness, but generally cause less illness and death and, therefore, would be expected to have lower public health and medical impact. Biological agents that were not believed to present a high bioterrorism risk to public health but which could emerge as future threats, as scientific understanding of these agents improved were placed in Category C. This book was written to provide a resource to scientists, epidemiologists, clinicians, and others in the field of bioterrorism defense. Instead, representative topics, authored by international experts provide a unique and state-of-the-art perspective on this field. The book consists of this preface and nine other chapters that address the broad areas of (1) detection capabilities (ie spatiotemporal disease surveillance; diagnostic bioterrorism response strategies; methods for detecting the presence of botulinum neurotoxins in food and other biological samples; and detection of bacillus spores by surface-enhanced Raman spectroscopy) and (2) characteristics of specific pathogenic microorganisms and toxins (ie Rickettsia and Rickettsial diseases; recent advances in the development of vaccines against Yersinia pestis; botulinum neurotoxins; ricin; and staphylococcal enterotoxins). Stanker1 Foodborne Contaminants Research Unit, Western Regional Research Center, 1Agricultural Research Service, U. An increasingly common route of intoxication is associated with intravenous drug use resulting in wound botulism. Potential methods for toxin exposure include intentional contamination of the food and drink supply, or by aerosol spread, leading to inhalational botulism. The speed of recovery from botulism increases with the timely administration of antitoxin or medical interventions (Arnon et al. Thus, sensitive and rapid toxin detection and diagnostic methods are critical for improved recovery time, as well as, facilitate the epidemiologic study of outbreaks. Due to the potential for bioterrorism use, much effort and resources have been dedicated to the development of detection methods, treatment, and prevention of botulism. A multitude of assay formats have been developed over many years, with in some cases, reported sensitivities at the attomolar level (Grate et al. Many assays were designed for use in the validation of toxin production, for commercial purposes, or for high-throughput screening methods to identify therapeutics that inhibit toxin function. For detailed analyses and descriptions of detection assays please also refer to excellent reviews by (Grate et al. To date, seven different botulinum serotypes, indicated by letters A through G, have been identified. Serotype and subtype diversity may impact antibody and molecular-based assay designs. Toxin complexes that survive the gastric challenge translocate across the epithelial cell barrier (transcytosis) gaining access into the bloodstream, where the holotoxin is released. Peptides with fluorescent labels and quencher molecules have been designed and used in various forms of enzymatic activity assays. Assays designed for evaluating food must detect at least this amount in a typical portion. Since portions vary widely between individual foods, assay sensitivity requirements may vary with specific matrixes. Foods that typically have large portion sizes would require assays with lower detection limits. In contrast, detection levels for tests used in sera or other clinical matrices should be as sensitive as possible to account for low toxin levels. The lethal toxin intravenous dose varies between 20-200 ng in an adult human with approximately 5 liters of blood (Arnon et al. Taking into account natural degradation, and clearance of toxin in sera, the assay sensitivity for diagnostic evaluation must be in the low to sub-pg/ml range. Amino acid sequence differences can vary as much as 70% among serotypes (Hill et al.

Other reports claim that al-Qaeda had planned to erectile dysfunction jacksonville order generic viagra capsules line use cyanide osbon erectile dysfunction pump 100 mg viagra capsules free shipping, sarin erectile dysfunction without pills buy 100mg viagra capsules free shipping, or osmium tetroxide against large numbers of people in government buildings diabetic with erectile dysfunction icd 9 code generic viagra capsules 100mg free shipping, 17 transportation hubs erectile dysfunction pills cape town buy viagra capsules discount, and shopping centers in Britain, Jordan, and the United States. In 2002, British authorities arrested three men who were allegedly planning to use cyanide in an attack on the 18 London subway system. There are also reports of attempted acquisition of hydrogen cyanide; however, this substance would have to be disseminated in a high concentration in order to cause casualties. Additionally, the gas emits a strong odor of bitter almonds, thus increasing the chance that victims may 20 be able to evacuate the area before the substance becomes lethal. Al-Qaeda has also attempted to procure potassium cyanide, which can be used for cutaneous contamination if mixed with the right chemicals. However, since the substance may appear wet or greasy, it is likely that an individual who has come into contact with the substance would take notice and wash the affected area of skin immediately. There are also indications that al-Qaeda has pursued toxic industrial chemicals, such as those used in a foiled attack on government targets in Jordan in April 2004. In the mid-1990s, bin Laden associates allegedly attempted to purchase anthrax bacteria 23 and yersinia pestis (plague) in Kazakhstan. For one, Mohammad Atta and Zacharias 26 Moussaoui expressed interest in crop dusters prior to the 9/11 attacks. The same year, alQaeda associate Ahmad Rassam testified that bin Laden was interested in acquiring 27 aircraft to disseminate biological agents at low altitude. Also in 2001, interrogations of two captured militants in Malaysia led to allegations that al-Qaeda affiliate group Jemaah 28 Islamiyah was attempting to procure and weaponize biological agents. The network would need significant technical assistance to weaponize biological agents for use in a terrorist attack. Anthrax bacteria can be harmful if dispersed in aerosol form, or by personal contact. While anthrax bacteria in aerosol form is lethal, it is extremely difficult to weaponize Bacillus anthracis spores so they maintain virulence and are easily dispersed. The biological toxin ricin can be extracted from castor beans, and while deadly, it is only suitable for targeted poisonings as it is not contagious. Radiological Materials Although there is strong evidence to suggest that al-Qaeda has attempted to procure radiological material, there is no indication that the network has been successful in this endeavor. British authorities claimed to have discovered documents suggesting that the network had constructed a radiological dispersion device, or dirty bomb, at an 31 unspecified location in Afghanistan. In April 2001, Bulgarian businessman Ivan Ivanov reportedly told authorities that he had met bin Laden in China, near the Pakistan border, to discuss business plans for an 32 environmental company to purchase nuclear waste. In April 2002, another al-Qaeda member, Abu Zubayda, claimed that the network had the knowledge to construct a dirty 33 bomb and hinted that there may be such a device hidden in the United States. A more well-publicized case occurred in May 2002 with the arrest of al-Qaeda affiliate Abdullah alMuhajir (Jose? Padilla claimed that he was part of an al-Qaeda plot to detonate a radiological dispersal device in the United States. Reports in early 2004 indicate that al-Qaeda affiliate Midhat Mursi (Abu Khabab) may have constructed a radiological dispersal device. British officials arrested eight men in June 2004 after the discovery of information on explosives, chemicals, and radiological materials and building plans of the New York Stock Exchange, the International Monetary Fund in Washington, D. Reports in late 2004 suggest that an al-Qaeda affiliate by the name of Walid al-Misri told investigators that bin Laden may have purchased radiological material 37 from contacts in Chechnya. Nuclear Materials There are many exaggerated accounts of al-Qaeda procuring both radiological and nuclear 38 material in the form of an off-the-shelf explosive device. Reports in 1998 indicated that bin Laden had plans to acquire nuclear material from Chechen contacts as well as contacts 39 in Kazakhstan. Reports in 2000 allege that bin Laden sent associates to acquire enriched 40 uranium from unspecified Eastern European countries. There were also accounts in 2001 and 2002 that bin Laden had obtained enriched uranium rods and/or a suitcase nuclear weapon from the Russian mafia as well as a Russian-made suitcase nuke from Central 41 Asian sources. Also in 2001, reports surfaced that Pakistani scientists had shared nuclear 42 information with bin Laden. Although Paracha later denied the allegations, he admitted to meeting bin 43 Laden in 1999 to consider a potential business deal. Pakistani journalist Hamid Mir reported in 2004 that al-Zawahiri had claimed in an interview that the al-Qaeda network had acquired nuclear weapons from Central Asia. The al-Qaeda deputy leader allegedly told Mir that affiliates had traveled to Moscow, Tashkent, [and] countries in Central Asia 44 with the intent to purchase portable nuclear material. In 2001, Jamal al-Fadl claimed that he was responsible for investigating the purchase of uranium to be used in 45 the construction of a nuclear device in the early 1990s. Reports surfaced in 2004 that alQaeda had purchased nuclear devices from the Ukraine in 1998. In January 2005, German authorities arrested suspected alQaeda member Ibrahim Muhammad K. Muhammad had allegedly approached an unspecified source 49 in Luxembourg to facilitate the transaction. Moroccan investigators reportedly uncovered a plot by al-Qaeda affiliate group Salafia Jihadia to attack a French nuclear power plant at Cap de la Hague, Normandy. One major obstacle to the acquisition of a ready-made device is political will; it is highly doubtful that any regime would transfer such a device to this terrorist network for fear of discovery and subsequent armed retribution by the United States. Reports regarding nuclear weapons development are mostly speculative and highly sensational, although there have been numerous reports of attempts to acquire uranium on multiple 51 occasions. All available reports suggest that al-Qaeda has yet to acquire the requisite amount of fissile material to construct a nuclear device. Equally important, it appears that the network lacks the technical capability to assemble a nuclear device*even if it were to obtain many of the needed materials. The group would need significant technical assistance from nuclear scientists in order to manufacture a nuclear weapon. Of particular concern is the allegation that a small number of Pakistani nuclear scientists have had contact with al-Qaeda over the past decade. Specific reports allege that two Pakistani scientists transferred nuclear weapon 52 information to Osama bin Laden in the mid-to late 1990s. Three days after the arrests, a seventh man was detained in connection with the case. British authorities reported that at least one of the suspects had trained in an al-Qaeda camp in Afghanistan, while the others may have participated in terrorist training exercises in Chechnya and the 54 Pankisi Gorge area of Georgia. The case quickly became world news after British authorities reported the discovery of castor beans, equipment to process the beans, and 55 traces of ricin in the apartment shared by the original six suspects. Subsequent reports indicated that the men implicated in the ricin plot did indeed maintain connections to the al-Qaeda network and that Osama bin Laden had been directing a number of terrorist cells throughout Europe that were intent on producing poison to be used in terrorist attacks. Despite these numerous allegations, the nature of the London ricin plot remained in question. On April 13, 2005, a London jury acquitted four of the suspects in the ricin case. Information presented in the trial led to the conclusion that there had been no traces of ricin discovered in the London apartment. While field equipment used by chemical experts did test positive for ricin, subsequent laboratory tests revealed that the reading had been a 56 false positive. Furthermore, it appeared that the five-page document of crude instructions on how to produce ricin, cyanide, and botulinum toxin had been copied from the Internet, as opposed to having been taken from a terrorist training camp in Afghanistan, as previously suspected. Subsequent investigations revealed that the lists of chemical instructions discovered in the London apartment were direct translations from an 57 Internet site maintained in Palo Alto, California. The only suspect convicted in the trial was Kamel Bourgess, an Algerian who was already serving time in prison for the murder of a British constable in connection with the 58 case. Reports indicate that Bourgess had planned to smear a ricin mixture on door 59 handles in order to cause casualties in North London. However, it appeared that Bourgess was far from being able to carry out the attack, given the crude attempts to produce the poison. Even if he had successfully produced ricin, the substance would not be an appropriate agent to cause mass casualties. Since ricin is a biological toxin as opposed to a bacteria or virus, it is not contagious and cannot spread rapidly between individuals. The surest way to induce fatalities is to encourage inhalation or ingestion of the substance in a powder form or after it is dissolved in a liquid. Ansar al-Islam in Northern Iraq Ansar al-Islam originated in Kurdish northern Iraq and is one of the most active Islamist groups operating in Iraq since well before the 2003 coalition invasion. The group is significant in that it is an al-Qaeda affiliate that has engaged in the production of both biological and chemical agents, purportedly for use as terrorist weapons. Most reports indicate that Ansar has worked with both cyanide and ricin; however, there is no evidence to indicate that the group ever reached a stage of weaponization. Still other reports claim that Ansar had produced or acquired ricin and had 62 conducted biological warfare experiments. Investigations of the laboratory discovered in northern Iraq revealed that it was rudimentary and that the group was far 64 from achieving a real weapons capability. Ansar members claimed to have produced ricin, cyanide-based toxics, and aflatoxin 65 prior to the U. After the invasion, coalition forces also reportedly uncovered a three-volume manual that outlined steps for conducting chemical and biological experiments. The group had allegedly tested both substances in 67 preparation for future use, including experiments on live animals. Both ricin and cyanide are reasonable choices for a group that is planning to conduct a targeted attack because they are easier substances to manipulate than some of their more virulent or unstable counterparts. In addition, since very little would be needed for a limited attack, it makes sense to choose agents that are easy to acquire and/or produce. Ricin is one of the easier biological toxins to produce, while cyanide is a chemical that can be acquired from an industrial complex. However, despite the deadly nature of these substances, neither can be appropriately labeled as a weapon of mass destruction. Difficulties in weaponization mean that such substances are suitable only for targeted assassinations, as opposed to mass casualty attacks. In early 2002, American troops near Kandahar reported the discovery of an abandoned facility that 70 appeared to have been built to research/weaponize biological agents. Traces of ricin and 71 production instructions were also reportedly discovered in an al-Qaeda safe house. Reports from the late 1990s indicate that the network attempted to create a pesticide/nerve agent with 75 a very high absorption rate and that the substance was tested on dogs and rabbits. Indeed, there is evidence to suggest that al-Qaeda has conducted experiments using crude chemical agents, some of which included the use of cyanide. One of the most telling pieces of evidence is a training video uncovered by investigators in which a dog is enclosed in a box and killed with a chemical substance believed to include cyanide. For one, investigators have not reported the discovery of any kind of dispersal device, a main requirement for the use of a chemical or biological agent for weapons purposes. It would be a sin for Muslims not to try and possess weapons that would prevent the infidels from 78 inflicting harm on Muslims. Furthermore, it was reported that bin Laden hired an Egyptian nuclear scientist and was able to purchase one kilogram of uranium from 80 South Africa.

These patients should be considered for further medical evaluation and appropriate medical therapy immediately instituted erectile dysfunction hypogonadism buy viagra capsules 100mg free shipping, which may include hospitalization impotence zinc viagra capsules 100 mg without a prescription.

If the respiratory muscles become paralyzed or sufficiently weakened, intubation and assisted respiration may be necessary until recovery takes place. It is purified to a crystalline complex consisting of the neurotoxin, a non-toxic protein and four major hemagglutinin proteins. When chemically denervated, the muscle may atrophy, axonal sprouting may occur, and extrajunctional acetylcholine receptors may develop. These improvements include reduced angle of head turning, reduced shoulder elevation, decreased size and strength of hypertrophic 32 muscles, and decreased pain. Based on the results of well-controlled studies, 40-58% of patients with cervical dystonia would be expected to have a significant improvement in their symptoms. This effect is not associated with other types of electrophysiologic abnormalities, or with clinical signs of weakness or symptoms regarding either safety or efficacy. Repeat injections should be administered when effects from previous injections subside. Improvements include reduction of muscle tone, increase in range of motion, and in some patients reduction of spasticity-related disability. The presumed mechanism for headache prophylaxis is by blocking peripheral signals to the central nervous system, which inhibits central sensitization, as suggested by pre-clinical studies. The recommended quantities of neurotoxin administered at each treatment session are not expected to result in systemic, overt distant clinical effects, i. However, clinical studies using single fiber electromyographic techniques have shown subtle electrophysiologic findings consistent with neuromuscular inhibition. Molecular mass: 900kD Structural formula: the Purified Neurotoxin Complex is a 900 kD complex composed of a 150 kD neurotoxin, a 130 kD non-toxic, non-hemagglutinating protein, and various hemagglutinins ranging between 14 and 48 kD. The neurotoxin, before nicking, consists of 1296 amino acids (1295 after the Met at the N-terminus is cleaved. In one study, injection of botulinum toxin was evaluated in 27 patients with essential blepharospasm. Twenty-six (26) of the patients had previously undergone drug treatment utilizing benztropine mesylate, clonazepam and/or baclofen without adequate clinical results. Three of these patients then underwent muscle stripping surgery, again without an adequate 35 outcome. Twenty-five (25) of the 27 patients reported improvement within 48 hours following injection of botulinum toxin. Blepharospasm in one of the other patients was later controlled with a higher dosage of botulinum toxin. The remaining patient reported only mild improvement but remained functionally impaired. In a double-blind, placebo-controlled study, 12 patients with blepharospasm were evaluated; 8 patients received botulinum toxin and 4 received placebo. All patients who received botulinum toxin improved compared to none in the placebo group. Among the botulinum toxin-treated patients, the mean dystonia score improved by 72%, the self-assessment score rating improved by 61%, and a videotape evaluation rating improved by 39%. Fifty-five percent (55%) of these patients were improved to an alignment of 10 prism diopters or less when evaluated six months or more following injection. These results are consistent with results from additional open label trials which were conducted for this indication. These improvements include reduced angle of head turning, reduced shoulder elevation, decreased size and strength of hypertrophic muscles, and decreased pain. Based on the results of wellcontrolled studies, 40-58% of patients with cervical dystonia would be expected to have a significant improvement in their symptoms. In a double-blind, vehicle-controlled parallel study, 51 patients with idiopathic cervical dystonia (spasmodic torticollis) were evaluated. There was also a significant decrease in strength and size of the contralateral sternocleidomastoid and trapezii. Vehicle-treated patients showed a mean decrease of only 0 to 4 degrees (0% to 6%) of head rotation at rest, and had no change in muscle strength or size. The difference in head rotation between treatment groups was statistically significant. Improvement was reported by 8%, 8% and 17% of vehicle-treated subjects at the same time points, respectively. The Physician Global Assessment showed parallel statistically significant improvements. Improvements in wrist, elbow and finger flexor muscle tone were reported at the highest dose in each study at various timepoints. The Physician Global Assessment also showed significant benefit at doses ranging from 75 to 360 units at various timepoints. Equinus foot In a three-month, double-blind, placebo-controlled, parallel study, 145 ambulatory children with cerebral palsy, 2 to 16 years of age, were evaluated. Patients exhibited muscle spasticity of the lower extremity(ies) associated with an equinovalgus foot position during gait. No significant changes in electromyography were seen in the placebo-treated patients. In a long-term, open-label study, 207 patients were evaluated for up to three years. Treatment responders were defined as subjects showing at least a 50% reduction from baseline in axillary sweating measured by gravimetric measurement at 4 weeks. A total of 1,384 chronic migraine adults who had either never received or were not using any concurrent headache prophylaxis, had > 15 headache days, with 50% being migraine/probable migraine, and > 4 headache episodes during a 28-day baseline phase were studied in 2 phase 3 clinical trials. Accordingly, for the least-squares means difference between treatment groups, 99% confidence intervals are displayed rather than 95% confidence intervals. Each secondary variable could only indicate significance if the primary variable and each secondary variable ranked ahead of it indicated statistical significance. The treatment effect appeared smaller in the subgroup of male patients (N=188) than in the whole study population. Neurogenic Detrusor Overactivity associated with a neurologic condition Two double-blind, placebo-controlled, randomized, multi-center Phase 3 clinical studies were conducted in patients with urinary incontinence due to neurogenic detrusor overactivity who were either spontaneously voiding or using catheterization. A total of 691 spinal cord injury or multiple sclerosis patients, not adequately managed with at least one anticholinergic agent, were enrolled. Significant improvements in urodynamic parameters including increase in maximum cystometric capacity and decreases in peak detrusor pressure during the first involuntary detrusor contraction were 40 observed. These primary and secondary endpoints are shown in Tables 8 and 9, and Figures 1 and 2. Retreatment criteria were: patient request, at least 12 weeks since previous treatment, and < 50% reduction (Study 1) or < 30% reduction (Study 2) from baseline in urinary incontinence episodes. In the pivotal studies, none of the 475 neurogenic detrusor overactivity patients with analyzed specimens developed the presence of neutralizing antibodies. Significant improvements compared to placebo were also observed for the daily frequency of micturition, urgency, and nocturia episodes. For all efficacy endpoints, patients experienced consistent response with re-treatments. Retreatment criteria for all phase 3 studies were: patient request, at least 12 weeks since previous treatment, and at least 2 urinary incontinence episodes in 3 days. In the pivotal studies, none of the 615 (0%) patients with analyzed specimens developed the presence of neutralizing antibodies. The proportions achieving at least a 75% and 50% reduction from baseline in urinary incontinence episodes were 46. The proportions achieving at least a 75% and 50% reduction from baseline in urinary incontinence episodes were 44. The proportions achieving at least a 75% and 50% reduction from baseline in urinary incontinence episodes were 47. When chemically denervated, axonal sprouting may occur, and extrajunctional aceylcholine receptors may develop. Higher dosages (8 and 16 U/kg) were associated with dose-dependent reductions in fertility in male rats, and the cohabitation period was slightly increased at dosages of 16 U/kg. Altered estrous cycling (prolonged diestrus) and interrelated reductions in fertility occurred in the female rats dosed with 16 U/kg. No teratogenic effects were observed when presumed pregnant mice were injected intramuscularly with doses of 4 U/kg (approximately 2/3 of the maximum recommended human dose) and 8 U/kg on days 5 and 13 of gestation; however, dosages of 16 U/kg induced a slightly lower fetal body weight. No teratogenic effects were observed in rats when injected intramuscularly with doses of 16 U/kg on days 6 and 13 of gestation, and 2 U/kg/day on days 6 through 15 of gestation. No effects on maternal reproductive performance were observed at the highest dose tested, 16 U/kg (approximately three times the maximum recommended human dose). No adverse effects on development of the pups were observed at 4 U/kg; however, higher dosages were associated with reduced pup body weight and/or pup viability at birth. There was evidence of systemic toxicity in animals treated with 8 U/kg and 16 U/kg. Systemic effects included a slight transient decrease in body weight gains in animals receiving 12 U/kg. In a study to evaluate inadvertent peribladder administration, bladder stones were observed in 1 of 4 male monkeys that were injected with a total of 6. No bladder stones were observed in male or female monkeys following injection of up to 36 Units/kg (~12X the human dose) directly to the bladder as either single or 4 repeat dose injections or in female rats for single injections up to 100 Units/kg (~33X the human dose). In a 9 month repeat dose intradetrusor study (4 injections), ptosis was observed at 24 Units/kg, and mortality was observed at doses? In an indirect hemagglutination assay, mice were immunized once per week for two weeks. Controlled trial of botulinum toxin injections in the treatment of spasmodic torticollis.

Afferent outflow can be considered a function of wall stress; therefore erectile dysfunction more causes risk factors buy viagra capsules 100mg without prescription, clinically, this scenario would result in a delayed desire to void. Conversely, when a small volume of urine is passed, there is a dramatic decline in wall stress, resulting in a reduction in afferent activity, which in turns leads to an early termination of detrusor contraction and thus reduced voiding efficiency. From these studies, two things are evident: 1) most criteria assess only detrusor contraction strength (as opposed to sustainability or speed), and 2) estimation of strength is based on the Qmax and PdetQmax, with threshold values set around the lower limits of the normal range (for men, this range is derived from historical series of patients undergoing bladder outlet surgery) (29,117). As such, some authors have studied healthy young men (118,119) and women (66) to obtain a more accurate picture, although these studies are few. Some of these are rather confusing, which may be the reason for their limited use in clinical studies. Consequently, methods that assess isovolumetric detrusor pressure have been suggested and are either based on post hoc mathematical analysis of urodynamic data or real-time interruption of urine flow (Table 4). Uncomfortable or painful for testing isovolumetric contraction patients Mechanical stop test strength 2. No information on sustainability of Continuous occlusion contraction (continuous occlusion) 4. This is represented by the following formula, where Pdet represents detrusor pressure, vdet is detrusor shortening velocity, and a and b are fixed constants (a=25 cm H2O, b=6 mm/s), obtained from experimental and clinical studies (122). However, it does not provide a Detrusor Underactivity 313 measure of contraction sustainability and involves a complex calculation limiting its use in routine clinical practice. Additionally, there are no validated threshold values of normality, although experts have suggested 7 W/m2 (16). In common with the watts factor, these methods do not measure the sustainability of contractions. This is unlikely to be applicable in other groups; an angle of 1 cm H2O/mL/s was found to be more accurate in older women (65). In voluntary stop tests, the patient is asked to interrupt the flow mid-stream by contracting the external urethral sphincter. Mechanical interruption, on the other hand, involves blocking the urethra, for example by pulling a catheter balloon against the bladder neck mid-stream. A continuous occlusion test has been described, where the outflow is occluded before the onset of detrusor contraction. The three techniques show good correlation with one another in both males (129) and females (130). However, the voluntary stop test gives a Pdet,iso of around 20% less than the other two (129). This is thought to occur due to a reflex inhibitory effect on the detrusor as a result of external sphincter contraction. Voluntary stop tests are not possible in some patients, especially in those with neurological dysfunction, stress incontinence, or frailty. However, continuous occlusion is problematic, as it does not allow the measurement of flow, it may be painful, and it is impractical. Another technique is to use condom catheters, where a continuous column of fluid from the condom via catheter to the urethra and bladder allows measurement of pressure. Several problems can lead to artifacts, such as leakage around the condom, closure of the external sphincter in response to line occlusion, and increased compliance within the system (133). One problem common to both techniques is the lack of appreciation of abdominal straining. Shortening velocity was calculated using the following equation, where Q represents the flow rate (mL/s), V represents bladder volume (mL), and Vt represents the volume of non-contracting bladder wall tissue. Eventually there is a reduction in the number of cross-bridges, which accounts for the reduced strength (136). Invariably, patients are managed in a generalized fashion, with either a watchful waiting approach or bladder drainage. Most other approaches are currently experimental and include modalities such as intravesical or injection-based treatments, neurostimulation/modulation, and innovative reconstructive surgical procedures involving transposition of the abdominal muscle groups. The main finding was that there was no significant deterioration in symptomatic or urodynamic parameters over time. Problems include urethral bleeding (one third of patients) (140) and false passages. Additionally, the technique can be time-consuming and socially restricting, and some patients may be unable to overcome the psychological barriers of fear of self-harm or infection (141). A common problem to all these agents is the systemic side effects of cholinergic agonism, including nausea, bronchospasm, abdominal cramping, flushing, and visual disturbance, which limit their dosing. A rare but serious complication is severe cardiac depression resulting in cardiac arrest. Most studies have assessed the efficacy of agents in either the prevention or treatment of acute urinary retention in the post-operative setting, including prostatectomy (142), anorectal surgery (143), vaginal surgery (144), and radical hysterectomy (145), as well as in post-partum patients (146). The results of these have recently been summarized in a review by Barendrecht et al. Only in three out of 10 trials reviewed was there a statistically significant benefit of the agent versus the control, in six studies there was no significant benefit, and in one a detrimental effect was observed. Bethanechol was used in all three studies showing a statistically significant benefit and the effect was marginal; a further four studies showed no benefit with the same agent. Prostaglandin E2 is thought to increase detrusor pressure and relax the urethra (155,156). As urethral sphincter contraction has an inhibitory effect on detrusor contraction (guarding reflex) (169), and inadequate relaxation may result in low-pressure low-flow voiding (170), there is a strong rationale for approaches aimed at preventing urethral contraction. Video-urodynamic studies were performed at baseline and 1-month follow-up after injection. Analysis of baseline characteristics identified the responders as having normal bladder sensation during filling; in contrast, non-responders had poor bladder sensation (mean volume at first sensation: 233 vs 368 mL, p=0. In 87% of the responders, recovery of detrusor contractility was associated with poor relaxation of the urethral sphincter. Anterior sacral root stimulators have long been used in patients with spinal cord injury to achieve continence and bladder emptying. The stimulator consists of an implantable receiver, stimulation wires, and an external transmitter. To trigger voiding, a radio transmitter is placed over the skin where the receiver lies (usually on the abdomen), which is connected by cables to the spinal electrodes that pass on the electrical impulses to the nerves. Brindley first implanted these stimulators in 1982 (173) and the first 50 cases were subsequently reported (174). All patients were shown to have evidence of at least some innervation to the detrusor pre-operatively, indicated by the presence of reflex contractions during filling or electroejaculation where no contraction occurred. The results showed that bladder emptying could be achieved in most patients and have been reproduced by other groups (175). Sauerwein subsequently modified the technique by combining it with total sacral root rhizotomy, thereby abolishing all reflex activity (176). Transurethral electrotherapy was first described by Katona in 1958 (177) and was revisited by several groups in the 1970s to 1990s. Stimulation occurs via an electrode placed on the tip of a catheter connected to a stimulator by an intraluminal wire. A neutral electrode is connected to an area of normal sensation elsewhere on the body. The current is applied and can be varied in terms of intensity, pulse duration, etc. Activation of mechanoreceptor afferents is thought to lead to restoration of bladder sensation and thereby to sufficient activation of bladder efferents (178) rather than direct activation of myocytes. Many reports have demonstrated enhanced bladder sensation and improved detrusor contractions; however, this has not always translated into an improvement in volitional voiding. Electrotherapy is usually conducted along intensive bladder training, which can be partially responsible for successful outcomes (181). A major drawback is the time-consuming requirements (daily sessions of 1 hour or more) and 10?15 sessions considered a trial period. There are no standardized treatment schemes and the technique remains experimental, receiving little attention in recent years. The primary outcome measures were recovery of detrusor contractility (based on parabolic detrusor contraction waveform) and method of voiding (normal, straining, or catheter). The overall proportion of patients needing an indwelling catheter decreased by 43%, whereas only 8% of the controls with normal compliance regained contractility. Sacral neuromodulation has been used to good effect in patients with reduced contractility and poorly relaxing sphincters (183,184). Neuromodulation may work by blocking urethral inhibition of afferent signals from the bladder, resulting in restoration of transmission of afferent signals to the brain and a resumption of bladder sensation and voiding (185). A similar picture may be seen in spasticity of the pelvic floor associated with pain, where neuromodulation may inhibit pain and enhance detrusor contraction. Eighteen patients had urodynamic data from the baseline assessment available and 16 had data at follow-up. There was no significant difference in the proportion of patients reporting storage or voiding symptoms. Reconstructive surgery Detrusor myoplasty was first reported in man in 1998 by Stenzl et al. Microsurgical anastomosis of the muscle pedicle to the inferior epigastric vessels with nerve coaptation to the intercostal branch is undertaken before wrapping the muscle in a spiral arrangement around the bladder, covering approximately 75% of its surface. The muscle is then fixed to the ligamentous and fascial structures of the pelvic floor based on intra-operative considerations. A total of 24 catheter-dependent patients with acontractile detrusors underwent the procedure with a median follow-up of 46 months. Etiologies included tethered cord syndrome, spinal cord injury, idiopathic, and acontractility post-hysterectomy. Compliance was >50 mL/mbar in all patients and vesico-ureteric reflux was identified post-operatively. The overall complication rate was 33% and included thromboembolism, pelvic abscess, and wound infection, although this rate would seem acceptable given the complex experimental nature of the procedure. There was no long-term donor site morbidity (muscular deficit or chronic pain) reported, although this has to be interpreted with caution given the small numbers. Ultrastructural changes accompanying aging and disease appear to tell part of the story. The possible roles of the afferent and efferent systems, as well as central control mechanisms, are important avenues for future study. Electrotherapy remains experimental, and a transcutaneous method would be more acceptable than trans-urethral. Detrusor myoplasty is potentially an option for younger patients that accept the risk of surgical morbidity, but expertise with this procedure is currently limited to a small number of groups worldwide.

In some dogs erectile dysfunction tumblr generic 100mg viagra capsules otc, arecoline may cause abnormally severe and prolonged stimulation of mucous secretions erectile dysfunction foods to eat buy viagra capsules 100 mg free shipping, characterised by excess salivation and anal discharge of watery mucus erectile dysfunction fact sheet purchase 100 mg viagra capsules visa. This may lead to impotence causes order viagra capsules 100 mg dehydration which should be countered by access to erectile dysfunction treatment melbourne generic viagra capsules 100mg on line water at all times. In animals that actively resist treatment, a significant amount of the drug may be absorbed through the mucosa of the mouth or throat during dosing; this can lead to a fall in blood pressure, incoordination, loss of consciousness, cyanosis, and laboured respiration. These effects can be reversed by artificial respiration and the injection of between 0. One third of the dose is given intravenously, and the remainder subcutaneously or intramuscularly. Pregnant bitches and animals with cardiac abnormalities should not be treated with arecoline. To obviate any possibility of bowel puncture by bone fragments, dogs should not be fed bone for three days before treatment. Dosing should not be carried out on a full stomach, although preliminary starvation is not necessary. Older dogs that are habitually constipated may require a dose of liquid paraffin 1-2 days before treatment. As some dogs resist purgation, the additional use of arecoline hydrobromide as an enema has been recommended, but the worms may not be reached by this procedure and it may thus lead to false negative interpretations. Dogs that purge successfully produce at least two motions; the first will be formed faeces and can be ignored, but the mucus that follows may be productive. Preferably, the mucus sample (about 4 ml) is diluted with 100 ml tap water, covered with a thin layer of 1 ml of kerosene (paraffin) and boiled for 5 minutes. Echinococcosis/Hydatidosis 173 d) Flotation technique this technique is independent of a piped water supply and relies on the fact that Echinococcus floats in a medium with specific gravity of about 1. The faecal sample is placed directly into a fine meshed (80-100 meshes/linear inch) wire basket (no. If a faecal mass contains large particles it may be placed in a coarse mesh (10 meshes/linear inch) basket (no. After boiling, a stainless-steel collecting pan with a cone in the centre and having a 5 cm opening at the apex and a wall 15 cm deep and 10 cm wide (no. If no worms are detected initially, the flotation should be repeated at least twice. Another method employs a constant stream of water to wash boiled mucous faeces through a sieve. For field surveys, a mesh of 80-90 meshes per linear inch can be used; and for laboratory studies, a mesh of 120 meshes per linear inch, in order to obtain a cleaner sample. This should be repeated several times, until the majority of the light flocculent material has been removed in the supernatant fluid. The sediment is examined for worms by pouring a small amount at a time into a black tray containing saline. This is considered to give more accurate results and is less damaging to the worms than other methods. Serological tests There are no satisfactory serological methods of diagnosis for adult echinococcosis. Arecoline hydrobromide is a white crystalline powder, odourless, with a bitter taste. Arecoline-acetarsol is the arecoline salt of 3-acetamido-4-hydroxyphenyl-arsonic acid and is a white or very pale yellow, somewhat glistening powder, almost odourless. Its action results in sweating, and stimulation of salivary, lachrymal, gastric, pancreatic, and intestinal glands. It increases intestinal tonus and mobility of smooth muscle, and this effect is responsible for purgation. Arecoline also has a direct action on the worm itself, by causing its paralysis but not death, making it relax its hold on the intestinal wall. Echinococcosis/Hydatidosis 175 Administration of the drug the use of the drug in tablet form and administered by means of a tablet gun is strongly recommended. Standard tablets of arecoline hydrobromide are preferably coated with sugar to disguise its taste and to avoid the development of allergic reactions in handlers with skin sensitivity. The accepted dose rates for tablets each containing 25 mg arecoline hydrobromide are: Minimum: 1 tablet per 14 kg body weight Maximum: 1 tablet per 7 kg body weight Optimum: 1 tablet per 10 kg body weight Arecoline-acetarsol tablets may also be used, and are available under a number of trade names. It has been suggested that this preparation has fewer side effects than the hydrobromide salt. A standard Hquid solution may be recommended as follows: Arecoline hydrobromide: 15 mg/ml Saccharine (or sugar): 1. A schedule of a divided dose treatment frequently gives improved diagnostic results without increasing the side effects of the drug. This schedule, in which the minimum dose is given and followed 15-30 minutes later with a similar dose, is recommended provided that the total dose is not greater than the maximum recommended dose rate. A history of recent movement of animals into or through an endemic area is highly relevant, particularly when disease outbreaks occur 2-4 weeks later. Identification of the agent: Diagnosis of heartwater depends on the demonstration of rickettsias in vascular endothelial cells. Squash preparations are made of several areas of cerebellum, cerebrum, and hippocampus which are the best tissue sources. Smears of the intima of the jugular vein or larger blood vessels are also acceptable. These preparations are dried, fixed with absolute alcohol, dried and stained by Giemsa. Biopsies of brain can be obtained from live animals under strict aseptic conditions. Blood and spleen samples should be kept in insulated containers for examination as soon as possible. Specimens of ticks can be transported frozen in dry ice, or preferably in liquid nitrogen. Fresh or uncoagulated whole blood from suspect animals taken during the febrile period may be subinoculated into susceptible bluetongue-immune sheep to confirm the disease in areas where bluetongue is endemic. Peritoneal macrophages from mice infected with the Kumm isolate have been employed in immunofluorescence tests, and primary neutrophil cultures provide a rapid and simple method of obtaining large amounts of C. It is also known by the synonyms veld poisoning, pericardite exudative infectieuse (French), Herzwasser (German), and hidrocarditis infectiosa (Spanish). It exists as an enzootic in the regions of Africa and Madagascar (36, 37) that are infested with ticks of the Amblyomma species. Many wild ruminants, including antelopes, are susceptible and can act as reservoir hosts (3, 29). Indigenous breeds of cattle, goats and sheep may be more resistant than imported breeds. A provisional diagnosis of heartwater is based on an assessment of the history of the disease outbreak, the spectrum of clinical signs and the character of the lesions observed post-mortem. A history of recent movement of animals into or through an endemic area is highly relevant, particularly when disease outbreaks occur 2-4 weeks later (1). In stained smears under light microscopy, the small coccoid forms appear uniform, whereas the larger ones are pleomorphic and include rings, horseshoe shapes and bacillary forms (31). With the exception of the semicarbazones (gloxazone), the rifamycins, the sulphonamides and the tetra cyclines, the organism is not susceptible to antibiotics. Electron microscopy reveals that the rickettsias occur as clusters within a vacuole in the cytoplasm of infected endothelial cells (31). Infectivity has been associated with the leucocytes (18) as well as the red cells (14). The known vectors of cowdriosis are three host ticks of the genus Amblyomma in which infection is transstadial and not transovarial. Heartwater is not a natural disease of laboratory mice, although they can be infected by strains of Cowdria that vary in virulence. Most strains are not strongly infective for mice, and some will cause only scattered deaths in mice or eventually fail to infect them on repeated passage. Some strains will passage in mice, inducing clinical signs (26), and will retain their virulence for sheep. Some strains can be adapted to mice through alternating passages in mice and sheep. Fresh whole blood collected from febrile goats and maintained at 4?C for 72 hours is still infectious for mice (26). Blood collected from febrile goats in an anticoagulant and preserved with 10% dimethyl sulphoxide at -70?C or at -196?C remains infective for goats (23). Following natural infection by ticks the incubation period for the disease is 1-3 weeks (occasionally but rarely 5 weeks), with an average of 9-14 days. Clinical signs may vary from anorexia to depression accompanied by varying degrees of nervous involvement. Subendocardial and brain haemorrhages occur, but these are not common in sheep, and splenomegaly and lymphadenopathy can be found in experimentally infected small ruminants. In infected mice there is no pyrexia, but tachypnoea, lethargy, anorexia, incoordination, clinical hypothermia and anorexia may occur. Tissues are invaded by the sixth day after infection, coinciding with the hypothermia. Mice that die have a pulmonary oedema and acute interstitial pneumonia, with concentrations of the organism in endothelial cells of the lung capillaries. Their occurence is rare in the brain, but they may be seen in the kidney glomeruli. These cells are of bovine fetal origin and are used at their seventieth passage level. Difficulties in diagnosis can arise for a number of reasons, such as lack of adequate facilities in the field, the acuteness of disease onset, the collection of inappropriate samples, a lack of pathognomonic post-mortem lesions, a failure to obtain adequate squash preparations of brain, and the lack of simple serological tests. The disease can be confused with the acute forms of other conditions, such as anthrax, haemoparasitaemia, pasteurellosis, rabies, rinderpest, foot and mouth disease or poisoning. A tentative diagnosis of heartwater may be possible on clinical grounds and herd history. A preponderance of Amblyomma ticks in certain seasons may also lead to suspicion of the disease. The specimens required include: i) Smears prepared from several areas of the cerebral cortex, cerebellum, and hippocampus. Brain tissue smears are made by squashing matched, bead-like pieces between 2 microscope sudes, and then drawing them apart, so that 2 smears are obtained. The best brain crush smears are made by alternately crushing-smearing-lifting, cruslrmg-smearmg-lifting, etc. A modification (22) of the smear technique is to make a zig-zag smear of about 5 mm wavelength on a slide: the capillaries are deposited on each wave, and do not all accumulate at the end of the smear as with the other technique. Each smear is air-dried, fixed in absolute alcohol or methanol for 5 minutes, and stained by Giemsa. All fixed smears are forwarded unrefrigerated: blood and spleen specimens should be packed in ice for immediate transport. To detect the agent in the squash preparations of brain (22, 32), areas containing several unconvoluted capillaries are located first by low power microscopy. Individual capillaries can then be examined more precisely by high power microscopy.
