Some areas of each meniscus lack an arterial blood supply and thus these areas heal poorly if damaged generic robaxin 500mg with amex muscle relaxant properties of xanax. The knee joint has multiple ligaments that provide support, particularly in the extended position (see Figure 9. The fibular collateral ligament (lateral collateral ligament) is on the lateral side and spans from the lateral epicondyle of the femur to the head of the fibula. The tibial collateral ligament (medial collateral ligament) of the medial knee runs from the medial epicondyle of the femur to the medial tibia. As it crosses the knee, the tibial collateral ligament is firmly attached on its deep side to the articular capsule and to the medial meniscus, an important factor when considering knee injuries. In the fully extended knee position, both collateral ligaments are taut (tight), thus serving to stabilize and support the extended knee and preventing side-to-side or rotational motions between the femur and tibia. The articular capsule of the posterior knee is thickened by intrinsic ligaments that help to resist knee hyperextension. Inside the knee are two intracapsular ligaments, the anterior cruciate ligament and posterior cruciate ligament. These ligaments are anchored inferiorly to the tibia at the intercondylar eminence, the roughened area between the tibial condyles. The cruciate ligaments are named for whether they are attached anteriorly or posteriorly to this tibial region. The cruciate ligaments are named for the X-shape formed as they pass each other (cruciate means “cross”). In this position, the posterior cruciate ligament prevents the femur from sliding anteriorly off the top of the tibia. The anterior cruciate ligament becomes tight when the knee is extended, and thus resists hyperextension. The medial and lateral menisci provide padding and support between the femoral condyles and tibial condyles. The collateral ligaments on the sides of the knee become tight in the fully extended position to help stabilize the knee. The posterior cruciate ligament supports the knee when flexed and the anterior cruciate ligament becomes tight when the knee comes into full extension to resist hyperextension. Which ligament of the knee keeps the tibia from sliding too far forward in relation to the femur and which ligament keeps the tibia from sliding too far backward? Since this joint is primarily supported by muscles and ligaments, injuries to any of these structures will result in pain or knee instability. Injury to the posterior cruciate ligament occurs when the knee is flexed and the tibia is driven posteriorly, such as falling and landing on the tibial tuberosity or hitting the tibia on the dashboard when not wearing a seatbelt during an automobile accident. More commonly, injuries occur when forces are applied to the extended knee, particularly when the foot is planted and unable to move. Anterior cruciate ligament injuries can result with a forceful blow to the anterior knee, producing hyperextension, or when a runner makes a quick change of direction that produces both twisting and hyperextension of the knee. A worse combination of injuries can occur with a hit to the lateral side of the extended knee (Figure 9. A moderate blow to the lateral knee will cause the medial side of the joint to open, resulting in stretching or damage to the tibial collateral ligament. Because the medial meniscus is attached to the tibial collateral ligament, a stronger blow can tear the ligament and also damage the medial meniscus. This is one reason that the medial meniscus is 20 times more likely to be injured than the lateral meniscus. A powerful blow to the lateral knee produces a “terrible triad” injury, in which there is a sequential injury to the tibial collateral ligament, medial meniscus, and anterior cruciate ligament. Arthroscopic surgery has greatly improved the surgical treatment of knee injuries and reduced subsequent recovery times. This procedure involves a small incision and the insertion into the joint of an arthroscope, a pencil-thin instrument that allows for visualization of the joint interior. These tools allow a surgeon to remove or repair a torn meniscus or to reconstruct a ruptured cruciate ligament. The current method for anterior cruciate ligament replacement involves using a portion of the patellar ligament. Holes are drilled into the cruciate ligament attachment points on the tibia and femur, and the patellar ligament graft, with small areas of attached bone still intact at each end, is inserted into these holes. The bone-to-bone sites at each end of the graft heal rapidly and strongly, thus enabling a rapid recovery.
To secrete fluids The body uses energy to secrete fluids such as saliva and breastmilk buy 500mg robaxin visa spasms shown in mri. To repair tissues After injury or illness, the body uses energy to repair damaged tissues. To move and work We need energy to move muscles, to move our bodies, to walk, to talk, to play, to run and to work. The population group that needs a lot of energy is children because they are very active (they run and play a lot) and their energy needs, based on their body weight are high.

Pregnancy — women do not receive enough care; the work burden of the mothers is not alleviated. Another belief is that pregnant mothers should not consume milk because the baby will have a whitish covering over its head when it is born. The health of your body depends on what you feed it on, just as a healthy plant or anything else will grow better in rich soil and good conditions. As you have learnt in this study session, everybody needs a variety of foods which contain enough different nutrients to keep them alive and healthy. Better nutrition means stronger immune systems, less illness and better health for people of all ages. Healthy people are stronger, more productive, and better able to break cycles of poverty and realise their full potential. Iron deficiency disorder reduces mental capacity and academic achievement of children. Iron deficiency anaemia affects energy levels as well as school attendance and performance. Childhood morbidities are compounded by iron, zinc and other nutrient deficiencies, leading to increased death rates. Nutrition depends on a good environment as this is important for the processes of food production up to its consumption. The availability of some nutrients (for example iodine) depends on a well-maintained environment. In this study session you have learnt about the magnitude of nutritional problems in Ethiopia. In addition, you have gained some knowledge about the basics of nutrition that you will use in your work. Summary of Study Session 1 In Study Session 1, you have learned that: 1 Ethiopia is affected by a high level of undernutrition (acute and chronic malnutrition). Health Extension Practitioners have an important role to play in providing information about nutrition to families in their communities. Write your answers in your Study Diary and discuss them with your Tutor at the next Study Support Meeting. You can check your answers with the Notes on the Self-Assessment Questions at the end of this Module. Can you name the different kinds of malnutrition and then describe the signs that might tell you that childhood malnutrition is a problem in your community? How can you persuade her that the family needs to eat many different kinds of food? Calculate the number of children under two and under five years old; then calculate the number of pregnant women in Afeta kebele who might need nutritional care and support. You will learn about the major categories of nutrients, the main sources of these, their function, and how our body uses each of these nutrients for healthy growth and development. It is important that everyone consumes these seven nutrients on a daily basis to help them build their bodies and maintain their health. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases. This study session will help you to explain to families and individuals in your community the importance of consuming a healthy and balanced diet, and how to do this with the resources available to them. Learning Outcomes for Study Session 2 When you have studied this session, you should be able to: 2. These are macronutrients, which should be consumed in fairly large amounts, and micronutrients, which are only required in small amounts.
Medullary respiratory centre: -Dorsal medullary respiratory neurones are associated with inspiration: It has been proposed that spontaneous intrinsic periodic firing of these neurones responsible for the basic rhythm of breathing discount robaxin 500 mg with amex muscle relaxant drugs. As a result, these neurones exhibit a cycle of activity that arises spontaneously every few seconds and establish the basic rhythm of the respiration. When the neurones are active their action potentials travel through reticulospinal tract in the spinal cord and phrenic and intercostal nerves and finally stimulate the respiratory muscles. These neurones are silent during quite breathing because expiration is a passive event following an active inspiration. However, they are activated during forced expiration when the rate and the depth of the respiration is increased e. During heavy breathing increased activity of the inspiratory centre neurones activates the expiratory system. In turn, the increased activity of the expiratory system inhibits the inspiratory centre and stimulates muscles of expiration. The dorsal and ventral groups are bilaterally paired and there is 8 cross communication between them. As a consequence they behave in synchrony and the respiratory movements are symmetric. Lesions covering this area in the pons cause a pathologic respiratory rhythm with increased apnoea frequency. What is known is nerve impulses from the apneustic centre stimulate the inspiratory centre and without constant influence of this centre respiration becomes shallow and irregular. This centre is a group of neurones that have an inhibitory effect on the both inspiratory and apneustic centres. It is probably responsible for the termination of inspiration by inhibiting the activity of the dorsal medullar neurones. Because in the lesions of this area normal respiration is protected it is generally believed that upper pons is responsible for the fine-tuning of the respiratory rhythm. Hypoactivation of this centre causes prolonged deep inspirations and brief, limited expirations by allowing the inspiration centre remain active longer than normal. The apneustic and pneumotaxic centres function in co-ordination in order to provide a rhythmic respiratory cycle: Activation of the inspiratory centre stimulates the muscles of inspiration and also the pneumotaxic centre. Then the pneumotaxic centre inhibits both the apneustic and the inspiratory centres resulting in initiation of expiration. Spontaneous activity of the neurones in the inspiratory centre starts another similar cycle again. Breathing in some extent is also controlled consciously from higher brain centres (e. In an unconscious person automatic control of the respiration takes over and the normal breathing resumes. Other parts of the brain (limbic system, hypothalamus) can also alter the breathing pattern e. In addition, stimulation of touch, thermal and pain receptors can also stimulate the respiratory system. There is evidence suggesting that in premature new-born babies this co-ordination is not mature enough and this could be responsible for the sudden infant death syndrome. Inflation of the lungs activates these receptors and activation of the stretch receptors in turn inhibits the neurones in inspiratory centre via vagus nerve. When the expiration starts activation of the stretch receptors gradually ceases allowing neurones in the inspiratory neurones become active again. In adults it is functional only during exercise when the tidal volume is larger than normal. O2-sensitive chemoreceptors (Peripheral chemoreceptors) are located at the bifurcation of the carotid artery in the neck and the aortic arch. They are connected to the respiratory centre in the medulla by glossopharingeal nerve (carotid body chemoreceptors) and the vagus nerve (aortic body). The conducting airways consist of a series of branching tubes which become narrower, shorter and more numerous as they penetrate deeper into the lung. The trachea divides into right and left main bronchi, which in turn divide into lobar, then segmental 12 bronchi. This process continues down to the terminal bronchioles, which are the smallest airways without alveoli. Since the conducting airways have no alveoli they do not take part in gas exchange but constitute the anatomical dead space.
Red flags – seriously consider secondary headache causes” • Host: Age>50 robaxin 500mg with mastercard infantile spasms 2012, immunocompromised, or coagulopathic. A schedule for the neuromuscle fellow on call is available on the neurology website under the fellows section in the employee info section. Pestronk prefers that the neuromuscle service be consulted for any patient on the ward service with a neuromuscular condition. The 2 doses can be run within a few hours of each other unless the patients are old (> 65 yo) or with comorbidities that increase their risk of developing thrombosis or renal failure. You may also be asked to send specific Pestronk antibody panels depending on the patient’s presentation (i. In patients with severe neuropathies, the gastrocnemius can often be “end stage” and of low diagnostic utility and a proximal muscle (i. Even if a patient has good numbers, if they are breathing too hard on your assessment, realize that he or she will tire out and suddenly decompensate. The neuromuscle fellow on call is available 24 hours per day and serves as your “chief” if you ever have any questions regarding ill patients on the neuromuscle service. Only treat high blood pressures if there is evidence of end organ damage or concurrent active coronary artery disease etc. Always keep track of your patient’s bowel movements and urine output as constipation and retention are not uncommon and both can lead to devastating outcomes if they go unrecognized. For all movement disorders patients: • Call Theresa at 747-0722 or Amy 747-2453 to obtain the last few notes for the patient. Note that Sinemet comes in regular (10/100 dark blue pill, 25/100 yellow pill, 25/250 light blue pill) and Controlled- Release (50/200 orange pill or 25/100 light brick pill). The attending or his nurse will specify how much Sinemet should be given in the morning (following a protocol); this is crushed and dissolved in orange juice for faster absorption. If midodrine is started then remember to tell patients to sit upright and don’t give it less than 4 hours before bedtime. Note that this has been shown to hasten recovery but the evidence does not show a change in long term outcome. Typically patients are started on injectable medications initially owing to their lower expense, better side effect profile, and need for less frequent and less intensive monitoring. Non- diabetic patients with high blood sugars on steroids may warrant diabetes consultation (they may need insulin at home while on steroids). Take a good history, ask about tinnitus, do the Dix-Hallpike maneuver for at least a minute in each position (have an emesis bucket handy! No test perfectly distinguishes central and peripheral vertigo, but searching for neighborhood signs that localize the lesion to the brainstem is paramount. Any one of the following is concerning for a central lesion: negative head impulse, nystagmus that is vertical or variable in its direction and skew (vertical misalignment) on cross cover fixation testing. Patients with peripheral vertigo may complain of “double vision” from nystagmus, but they should not have true diplopia or disconjugate eye movements on formal testing. Common Empiric Antibiotic Dosing for Meningitis in Adults Drug Dose Notes Vancomycin 15 mg/kg Modify dosage based on renal (actual dysfunction and age (see weight) q12 Toolbook). Cefepime 2 g q8 hrs Modify dosage in patients with renal dysfunction Ampicillin 2 g q4 hrs Modify dosage in patients with renal dysfunction. If sensation is intact to cotton wisp, it is probably not “numb” - Most patients with mild isolated facial paresthesias have no acute brainstem pathology if no neighborhood findings are present - Most patients with mild isolated limb paresthesias have an entrapment or radicular lesion if no weakness is present - Bilateral arm paresthesias may signify central cord syndrome, always image the C-spine - Hugging sensations may signify a transverse myelitis - Splitting the midline with vibration can be supportive of functional overlay, but does not rule out neurological disease Pseudoseizures - Always respond to the patients with concern, but do not give Ativan if it’s not a seizure - A reasonable number of true epileptics also have pseudoseizures. The consultation is usually for assistance with determining neurologic prognosis, or to rule out seizure. It is helpful to clarify with the primary team exactly what their question is at the time the consult is called, and if neurology remains on board for any length of time, continue to have discussions with the primary team about the role of the consulting neurology team. Myoclonus and other “jerks” in Hypoxic Ischemic Injury These patients frequently develop myoclonic jerking post-arrest and non- neurologists often interpret it as seizure. We do not treat it unless it is interfering with the patient’s care or is disturbing to the patient’s family. You can use benzodiazepines for treatment; alternatively, Keppra and valproic acid have some utility for myoclonic jerking. Post-arrest patients can also develop Lance—Adams syndrome, which causes myoclonic jerks but has a much better prognosis.
