Amyotrophic lateral sclerosis is a devastating progressive neurodegenerative disorder, involving motor neurons in the cerebral cortex, brainstem and spinal cord. Mean duration of survival from the time of diagnosis is around 15 months, being pulmonary complications and respiratory failure responsible for more than 85% of deaths. Albeit the inevitability of respiratory failure and short-term death, standardized intervention protocols have been shown to significantly delay the need for invasive ventilatory support, thus prolonging survival and enhancing quality of life. The authors present an intervention protocol based on clinical progression and respiratory parameters. Decisions regarding initiation of non-invasive positive pressure ventilation (NIPPV) and mechanically assisted coughing, depend on development of symptoms of hypoventilation and on objective deterioration of respiratory parameters especially in what concerns bulbar muscle function. These include maximum inspiratory capacity (MIC), difference between MIC and vital capacity (MIC-VC), and assisted peak cough flow (PCF). These standardized protocols along with patient and caregivers education, allow for improved quality of life, prolonged survival and delay or eventually prevent the need for tracheotomy and invasive ventilatory support. Supplemental oxygen should be avoided in these patients, since it precludes use of oxymetry as feedback for titrating NIPPV and MAC, and is associated with decreased ventilatory drive and aggravated hypercapnia.

It's 2000 HRS on a Friday evening. You're assigned to an ALS engine company, and you're just settling down after a busy day when you're dispatched along with a BLS ambulance to a report of a sick person outside a local club where they're holding a concert. During your response, dispatch advises that they're receiving multiple calls on the incident and are dispatching a second BLS ambulance to the call. * As you turn the corner and approach the scene, you notice a haze in the air coming from an industrial site on the same side of the street and see approximately 200 people exiting the club in haste. Several dozen patrons line the street between the club and the subway station. They're coughing and crying, and several are vomiting. * The driver stops the engine in front of the subway entrance, which is located approximately 500 feet from the club and uphill and upwind from the haze. The scene is overwhelming, even to the captain, who turns to you-as the paramedic on the crew-and asks what you want done first. Your first thought is, Triage. But you know that triaging these patients is more complicated than your everyday two-car collision.

Amyotrophic lateral sclerosis is a progressive neurodegenerative disease with no known cure. The major cause of mortality and major morbidities is related to the effects of the disease on the muscles of the respiratory system (ie, the inspiratory, expiratory, and upper airway muscles). Dyspnea, swallowing difficulties, sialorrhea, and impaired cough are all symptoms that can be palliated through pharmacologic and nonpharmacologic means. Noninvasive positive pressure ventilation, in particular, is a technique that not only relieves dyspnea but may also extend the lives of patients who have this disease. It should be offered to all patients who have amyotrophic lateral sclerosis with a forced vital capacity of less than 50 percent.

Neuromuscular diseases (NMD) may affect respiratory muscles, leading to respiratory failure. Studies show that long-term noninvasive mechanical ventilation (NIV) improves symptoms, gas exchange, quality of life and survival. NIV improved these parameters in muscular dystrophies and also in patients with amyotrophic lateral sclerosis without severe bulbar dysfunction. NIV should be started at the onset of nocturnal hypoventilation. In selected cases, NIV may be simpler, better accepted by patients and cheaper than invasive mechanical ventilation, but it cannot be used as an alternative. Tracheostomy may be preferred by patients unable to protect their airways and wishing to survive as long as possible, or by ventilator-dependent patients. Glossopharyngeal breathing consists of taking air and propelling it into the lungs. Chest percussions and vibrations can help to mobilise airway secretions but they cannot substitute coughing. Manually assisted coughing requires substantial lung inflation through air stacking or deep lung insufflation, followed by an abdominal thrust with open glottis. The combination of mechanical in-exsufflation with an abdominal thrust is a mechanically assisted cough. In conclusion, recent advances in respiratory care of NMD have improved prognosis and many caregivers have changed from a traditional noninterventional to a more aggressive, supportive approach.

Specialized and multidisciplinary care is needed for patients with amyotrophic lateral sclerosis (ALS). Respiratory failure secondary to respiratory muscle dysfunction, ineffective cough, weight loss and progressive loss of autonomy should always be sought and explored. Very few tests are needed to assess a patient with ALS: spirometry, blood gases, nocturnal oximetry, cough peak-flow, and follow-up of body weight. Patients should be informed clearly as to the nature and evolution of ALS, and as to the potential benefits and disadvantages associated with each treatment modality in order to be involved in therapeutic decisions. This evidence-based review focuses on respiratory care of patients with ALS.

Patients with amyotrophic lateral sclerosis (ALS) need a care programme as the disease progresses. We used telemedicine-assisted integrated care (TAIC) in 40 patients with ALS, for a mean duration of 8.6 months (range 1-12). A nurse-tutor played the key role, supported by respiratory physicians, neurologists and psychologists. Each patient used a portable pulse oximeter during the daily telephone contacts to assess clinical/oxygen variations. Patients also completed a satisfaction questionnaire. During the study period, each patient used TAIC at least five times per month. There were 1907 scheduled telephone calls (86% of the total) and 317 unscheduled calls. Of the unscheduled calls, 84% were managed by the nurse-tutor and only 16% of them required specialist intervention. The most common item was the ALS clinical interview (58%), followed by the description of acute symptoms, cough ability and oxygenation. TAIC staff recommended 4 out of 12 emergency hospital admissions (33%) and 77% of the other hospitalizations. Patients and caregivers were extremely satisfied (79%) with the nurse assistance provided and the patients' confidence in handling their disease improved in 71% of the cases. TAIC provides a nurse-centred, home-monitoring programme that can be a useful way of following up ALS patients.

Cough can be impaired in ALS. This can result in peak cough flows (PCFs) too low for an adequate airway clearance (<270 l/mn). There are several cough assistance techniques that aim at a better elimination of airway secretions, but which are effective, especially in bulbar patients, is not known. We designed the present investigation to compare the PCFs produced by a range of manual and mechanical techniques in patients with ALS, in non-bulbar but also in bulbar patients. In the whole study population, PCFs ranged from 84 (35-118) l/mn for the spontaneous cough manoeuvre to 488 (243-605) l/min for the in/exsufflator (p = 0.0005). In the bulbar group, these values were 42 (35-130) l/min versus 436 (244-630) l/min, respectively (p = 0.008), and 89 (40-106) l/min versus 491 (192-580) l/min, respectively, in the non-bulbar group (p = 0.019). There was no statistically significant difference between the bulbar and the non-bulbar groups. The in/exsufflator was not always the best tool. We conclude that capacity of coughing efforts to produce efficient peak cough flows can be dramatically improved with different tools, even in patients with very severe bulbar symptoms and that it appears useful to test an array of techniques to optimally tailor cough improvement techniques to individual patients.

The purpose of this article was to describe the use of noninvasive inspiratory and expiratory muscle aids to prevent chest wall deformities including pectus excavatum, to prevent respiratory complications of vertebral surgery, to prevent acute and long-term ventilatory insufficiency and failure in children with paralytic disorders who develop these deformities, and to permit the extubation and tracheostomy tube decanulation of "unweanable" patients. Noninvasive airway pressure aids can provide up to continuous ventilator support for patients with little or no vital capacity and can provide for effective cough flows for patients with severely dysfunctional expiratory muscles. An April 2010 consensus of clinicians from 20 centers in 14 countries reported over 1500 spinal muscular atrophy type 1 (SMA1), Duchenne muscular dystrophy (DMD), and amyotrophic lateral sclerosis (ALS) patients who survived using continuous ventilatory support without tracheostomy tubes. Four of the centers routinely extubated unweanable DMD patients so that none of their over 250 such patients has undergone tracheotomy.

The neuroanatomy of voice and speech is complex. An intricate neural network is responsible for ensuring the main functions of the larynx: airway protection, cough and Valsalva production, and providing voice. Coordination of these roles is very susceptible to disruption by neurological disorders. Neurological disorders that affect laryngeal function include Parkinson's disease, stroke, amyotrophic lateral sclerosis, multiple sclerosis, dystonia and essential tremor. A thorough neurological evaluation should be routine for any patient presenting with voice complaints suggestive of neurogenic cause. Endoscopic visualisation of the larynx using a dynamic voice assessment with a flexible laryngoscope is a crucial part of the evaluation and ancillary tests are sometimes performed. Otolaryngologic evaluation is important in the diagnosis and treatment of neurological disorders that affect laryngeal function.

There are many causes of frequent urination. Whenever water or fluids are consumed, the patient has to urinate within 10 or 20 min. Often urinary bladder examinations & blood tests show no significant abnormalities, & treatment by anti-bacterial or anti-viral agents does not improve the symptoms significantly. In intractable frequent urination with difficulty holding urine, as well as other intractable medical problems such as frequent coughing, white pus in gingiva, infection of the apex of a root canalled tooth, slow-healing wounds, & ALS, the authors often found coexisting mixed infections of Candida albicans (C.A.), Helicobacter pylori (H.P.), & Cytomegalovirus (CMV) with or without additional bacterial (Chlamydia trachomatis, etc.) or viral infections & increased Asbestos, with or without Hg deposits. We often found various degrees of mixed infections with C.A., H.P., & CMV in the external sphincters of the urethra & in the Trigone of the urinary bladder which consists of (1) a horizontal, band-like area between the 2 ureter openings & (2) the funnel shaped part of the Trigone at the lower half of the urinary bladder. In the coexistence of significant amounts of C.A., H.P. & CMV, the infection cannot be reduced by otherwise effective medicines for H.P. & CMV. However, one optimal dose of Diflucan, or Caprylic acid taken orally or externally applied, rapidly reduced the symptoms significantly. We found the best treatment is to give a combination of an optimal dose of Caprylic acid orally in the form of "CaprilyCare" or "Caprylic Acid," with a capsule of Omega-3 Fish Oil as an anti-viral agent, Amoxicillin, Substance Z & a Cilantro tablet. We found that an optimal dose of Caprylic acid increases normal cell telomere (NCT) to a desirable 750 ng BDORT units while Diflucan increases NCT by only 25 ng BDORT units, & with Omega-3 fish oil, leads to a mutual cancellation of both drugs. Thus, Caprylic acid is superior to & less expensive than Diflucan, & has potential application for anti-cancer, anti-aging, anti-Alzheimer's disease, anti-Autism, anti-infection, & general circulatory improvement.
