Myopathies can be manifested as either fixed weakness (muscular dystrophies allergy medicine heart disease buy cheap nasonex nasal spray line, inflammatory myopathies) or episodic periods of weakness with normal strength interictally (periodic paralysis secondary to channelopathies allergy treatment relief purchase nasonex nasal spray pills in toronto, metabolic myopathies secondary to certain disorders in the glycolytic pathway) allergy symptoms all the time purchase 18gm nasonex nasal spray amex. Disorders of muscles can have acute (<4 weeks) food allergy symptoms quiz order nasonex nasal spray 18gm with visa, subacute (4 to 8 weeks) allergy natural treatment vitamins cheap nasonex nasal spray online visa, or chronic (>8 weeks) periods over which the weakness evolves allergy symptoms ginger cheap nasonex nasal spray online master card. The disorders with episodic weakness have acute weakness that can return to normal strength within hours or days. The tempo of the disorders with persistent weakness can vary from (1) acute or subacute in some inflammatory myopathies (dermatomyositis and polymyositis) to (2) chronic slow progression over a period of years (most muscular dystrophies) or to (3) fixed weakness with little change over decades (congenital myopathies). Finally, both constant and episodic myopathic disorders can cause symptoms that may be monophasic or polyphasic (relapsing). On the other hand, abnormal fatigability after exercise can result from certain metabolic and mitochondrial myopathies, and it is important to define the duration and intensity of exercise that provoke it. Positive Symptoms Myalgia Muscle pain (myalgia) is a nonspecific complaint that accompanies some myopathies. However, muscle pain is surprisingly uncommon in most muscle diseases, and limb pain is more likely to be due to bone or joint disorders. It is rare for a muscle disease to be responsible for diffuse aching pain and discomfort in muscle if the results of neurologic examination and laboratory studies are normal. Cramps are usually localized to a particular muscle region and last from seconds to minutes. They are generally benign, occur in normal individuals, do not reflect an underlying disease process, and are seldom a feature of a primary myopathy. Cramps can occur with dehydration, hyponatremia, azotemia, and myxedema and in disorders of the motor neuron (especially amyotrophic lateral sclerosis) or nerve. Muscle Contractures Muscle contractures are uncommon but can superficially resemble cramps. They usually last longer than cramps and are provoked by exercise in patients with glycolytic enzyme defects. Contractures are electrically silent, whereas cramps are associated with rapidly firing motor unit discharges. Myotonias Myotonia is impaired relaxation of muscle after forceful voluntary contraction. Patients may complain of muscle stiffness or persistent contraction in almost any muscle group, particularly those involving the hands and eyelids. They will note difficulty releasing their handgrip after a handshake, unscrewing a bottle top, or turning a doorknob. With repeated exercise, the 6 myotonia improves: the so-called warm-up phenomenon. Paramyotonia is the paradoxical phenomenon in which exercise makes the myotonia worse. Rhabdomyolysis Patients who complain of exercise-induced weakness and myalgias should be asked whether their urine has ever turned dark or red during or after these episodes, which is indicative of myoglobinuria. Myoglobinuria follows excessive release of myoglobin from muscle during periods of rapid muscle destruction. Diagnosis the most important aspect of evaluating a patient with a myopathy is the information obtained from the history. After taking the history, the physician should formulate a reasonable preliminary diagnosis that places the patient into one of the categories in Table 2. The findings on physical examination, in particular the pattern of weakness, help further define the diagnosis. History A detailed family history should be obtained to look for autosomal dominant, recessive X linked, and vertical maternal (mitochondrial) patterns of transmission. Identifying a particular hereditary pattern is of help in diagnosis and genetic counseling. Does the ingestion of a high-carbohydrate meal precede the weakness, suggestive of a periodic paralysis Knee extension and hip flexion should be tested in the seated position, knee flexion should be tested prone, and knee abduction should be tested in the lateral decubitus position. An inability to walk on the heels or toes can indicate weakness in the distal leg muscles. Observe the patient talk and smile to determine whether 7 facial weakness is present. Does the patient have the so-called horizontal smile, indicative of lower facial muscle weakness Is the patient unable to close the eyes completely when asked to do so, indicative of upper facial muscle weakness The muscles that can be most easily percussed to look for myotonia are the thenar and wrist/finger extensor muscle groups. Once the myopathy is advanced and the muscles are extremely weak, reflexes can become hypoactive or unobtainable. Pattern of Weakness Once the muscles have been inspected and tested for power and functional activity has been observed, an attempt should be made to place the patient in one of the patterns of muscle weakness that can occur in myopathic disorders. This pattern of weakness can be seen in many hereditary and acquired myopathies and is therefore the least specific in arriving at a particular diagnosis. It is not known why most myopathic disorders selectively involve the proximal muscles. The pattern of distal weakness in the upper extremities (extensor muscle group) or lower extremities (anterior or posterior compartment muscle groups). Selective weakness and atrophy in distal extremity muscles are more often features of neuropathies and are uncommonly due to a primary muscle disease. When this pattern of weakness is determined to be due to a myopathic rather than a neuropathic disorder, a diagnosis of distal myopathy is appropriate. Examples include myotonic dystrophy, distal dystrophies (see later), titinopathy, zaspopathy, and inclusion body myositis. When this pattern is associated with facial weakness, it is highly suggestive of facioscapulohumeral dystrophy. Other hereditary myopathies can be associated with a scapuloperoneal syndrome, for example, scapuloperoneal dystrophy, Emery-Dreifuss dystrophy, acid maltase deficiency, and some congenital myopathies. The pattern of distal upper extremity weakness in the distal forearm muscles (wrist and finger flexors) and proximal lower extremity weakness involving the knee extensors (quadriceps). In addition, the weakness is often asymmetrical between the two sides, a pattern that is uncommon in most myopathies. The combination of ptosis, ophthalmoplegia without diplopia, and pharyngeal weakness should suggest the diagnosis of oculopharyngeal dystrophy, especially if the onset is in middle age or later. Ptosis and ophthalmoplegia without prominent pharyngeal involvement are hallmarks of many of the mitochondrial myopathies. Ptosis and facial weakness without ophthalmoplegia or pharyngeal weakness are common features of myotonic dystrophy. Therefore, the presence of ocular or pharyngeal muscle involvement can suggest a particular muscle disorder. Patients with ocular or pharyngeal involvement can also have the typical pattern of limb-girdle weakness. Some myopathic conditions have such a dramatic degree of weakness of the neck extensor muscles that the term dropped head syndrome is used. Neck extensor weakness can also occur with myopathies such as those with a limb-girdle pattern of weakness. Prominent neck extensor weakness is common in two other neuromuscular diseases: amyotrophic lateral sclerosis and myasthenia gravis. These six patterns of myopathy have limitations but are useful in narrowing the differential diagnosis. Patients with neuromuscular diseases other than myopathies can also have one of these weakness patterns. A muscle specimen can be obtained through either an open or a closed (needle or punch) biopsy procedure. The muscle biopsy findings can establish whether there is evidence of either a neuropathic or a myopathic disorder. A neuropathy can produce denervation atrophy with small angular fibers, groups of atrophic fibers, and as a result of reinnervation, groups of fibers of the same histochemical type and target fibers. Typical myopathic abnormalities include central nuclei, both small and large hypertrophic round fibers, split fibers, and degenerating and regenerating fibers. Inflammatory myopathies are characterized by mononuclear inflammatory cells in the endomysial and perimysial connective tissue between fibers and occasionally around blood vessels. Atrophy of fibers located on the periphery of a muscle fascicle, or perifascicular atrophy, is a common finding in a particular inflammatory myopathy, dermatomyositis. Any long-standing chronic myopathy can produce an increase in connective tissue and fat. Mitochondrial disorders are suggested by the identification of ragged red fibers on Gomori stain and various abnormal staining patterns on oxidative stains. Molecular Genetic Studies the specific molecular genetic defect is known for an increasing number of myopathies. Other Tests Electrolyte, endocrine, and immunologic tests are indicated to establish specific medical diagnoses. A decrease in the serum creatinine level is a useful indicator of decreased muscle mass. Forearm exercise testing in patients with a suspected metabolic myopathy is often performed to determine whether there is a defect in the glycolytic enzyme pathway. Historically, muscular dystrophies were categorized by their distribution of weakness, age at onset, and inheritance pattern. Advances in molecular understanding of the muscular dystrophies have defined the genetic mutation and abnormal gene product for many of these disorders (Table 3). Dystrophinopathies the dystrophinopathies include X-linked disorders resulting from mutations of the large dystrophin gene located at Xp21. Dystrophin is a large 427-kD subsarcolemmal cytoskeletal protein that along with other components of the dystrophin-glycoprotein complex, provides support to the muscle membrane during contraction. Large deletions, several kilobases to more than 1 million base pairs, can be demonstrated in approximately two thirds of patients; duplications occur in 5% of cases, and the remainder have small mutations that are not readily detectable. Deficiency of dystrophin weakens the sarcolemma and thus permits the influx of calcium-rich extracellular fluid, which then activates intracellular proteases and complement and leads to fiber necrosis. The proximal muscles are the most severely affected early (limb-girdle pattern), and the course is relentlessly progressive. Although patients are generally asymptomatic, heart failure and arrhythmias can occur late in the disease. The smooth muscle of the gastrointestinal tract is also involved, and intestinal pseudo obstruction occurs. If the patient falls into the third of patients in whom a deletion cannot be detected, muscle biopsy is required to demonstrate dystrophin deficiency by either Western blot or immunostaining. Muscle biopsy will also demonstrate typical features of a muscular dystrophy: variability in fiber size, fiber necrosis and regeneration, and replacement with connective tissue and fat. They remain elevated but tend to decline over the course of the disease, after severe loss of muscle mass has occurred. Prognosis Patients begin to fall frequently by 5 to 6 years of age, have difficulty climbing stairs by the age of 8, and are usually confined to a wheelchair by 12 years of age. Initially, calf hypertrophy is often present, but after ambulation is lost, all muscles atrophy. The proximal tendon reflexes (biceps, quadriceps) disappear by the age of 10, although gastrocnemius reflexes are often preserved until late in the disease. Respiratory function gradually declines, and decreased vital capacity can be detected after the age of 10. Calf hypertrophy is often prominent, and patients may complain of exercise-induced calf pain as an early symptom. Patients usually remain ambulatory after the age of 15, and the average age when a wheelchair is required is 30 years. The different dystrophin phenotypes are determined by the site of the mutation in the dystrophin gene and the effect or lack of effect of the mutation on expression of the cardiac isoform of dystrophin. Female carriers are generally asymptomatic, but they may rarely demonstrate moderate limb-girdle weakness. A more accurate method of carrier detection is to look for an Xp21 deletion, which will be present if the affected males in the family are among the 60% who have a dystrophin gene deletion (or duplication). Prenatal genetic testing can be performed on amniotic fluid cells or chorionic villi. Prednisone also delays respiratory compromise, but it cannot prevent deterioration and death. Side effects of therapy include weight gain, growth delay, and changes in behavior. Gene therapy for the dystrophinopathies and other muscular dystrophies with known genetic mutations is still in preclinical stages. Emery-Dreifuss Dystrophy Emery-Dreifuss dystrophy is an X-linked muscular dystrophy. Clinical Manifestations the disease is characterized by the clinical triad of (1) early contractures of the elbows, ankles, and posterior cervical muscles; (2) slowly progressive muscle weakness, usually in a scapulohumeroperoneal distribution; and (3) cardiomyopathy with atrial conduction defects. The early elbow contractures are often an important phenotypic key to the diagnosis. The normal emerin perinuclear staining pattern in these tissues will be absent in Emery Dreifuss dystrophy. Prognosis Although Emery-Dreifuss dystrophy usually begins in childhood, most patients remain ambulatory into their third or fourth decades.

One-day disposable lenses allergy shots vs medicine generic nasonex nasal spray 18 gm, which are worn once and require no maintenance or storage allergy testing alcat order 18gm nasonex nasal spray with visa, are becoming increasingly popular allergy forecast burlington vt buy nasonex nasal spray with mastercard. Extended wear involves much greater risks and increases the chances of complications such as ulcerative keratitis allergy testing mold cheap 18gm nasonex nasal spray with visa, Acanthamoeba keratitis and papillary conjunctivitis allergy medicine heart palpitations trusted nasonex nasal spray 18gm. Contact lenses should not be worn if the patient has conjunctivitis or is using eye drops allergy testing joplin mo 18gm nasonex nasal spray overnight delivery. Soft contact lenses can absorb the preservative benzalkonium chloride used in eye drops. Consequently, soft lenses should not be worn within 24 h of instilling eye drops containing this preservative. Eye problems in practice Paul Greet is a man in his forties who comes into your pharmacy on his way home from work wanting treatment for a stye. He asks if you would make him an emergency supply of chloramphenicol eye ointment, which his doctor usually prescribes for him. Potential Potential Potential Consequences What would I do if the harm to harm to benefit to for pharmacist patient were me/my patient patient patient of supplying/ spouse/my parent/my from not from from not supplying child However, the pharmacist will take into account the consequences of not making a supply, including suffering and any potential harm from delayed treatment. A stye can be an external one: a localised infection of the hair follicles of the eyelid margin; or an internal stye: an infection of meibomian glands on the inner surface of the lid. A way of doing this would be to dip a cotton wool bud in hot water and then gently press it against the stye. Often chloram phenicol ointment is prescribed more to protect the eye from any discharge rather than actually treat the stye. It would probably help Paul Greet to understand the natural course of styes, although if he has used chloramphenicol ointment in the past, he is likely not to be happy without a further supply this time. Sometimes recurrent styes can be associated with blepharitis, diabetes or raised lipids. A key issue for the pharmacist is the potential risk from not examining the inside of the ear and seeing how the ear looks. Diagno sis is thus best made by the doctor, who can examine the ear with an auriscope or otoscope. What you need to know Wax Otitis externa Otitis media Glue ear One or both ears affected Significance of questions and answers Wax Symptoms Wax blocking the ear is one of the commonest causes of temporary deafness. The ear can be unblocked by using ear drops such as olive oil and various proprietary drops. A cotton wool plug should be applied to retain the fluid and be kept in for at least 1 h or overnight. Cotton wool buds should not be poked into the ear as wax is just pushed further in and it is possible to damage the eardrum. If any wax remains despite this treatment, referral to the doctor is advisable so that the wax can be considered for syringing. The use of drops to soften the wax prior to syringing the ears is recommended to make the procedure more effective. In the former (due to a furuncle or boil), the main symptom is ear pain and in the latter, a combination of some or all of pain, itching, hearing loss and dis charge. It is more frequent in hot and humid environments and is ten times more common in summer than winter. It is possible that the same symptoms can arise from a middle ear infection (otitis media) with a perforated eardrum. It is often intense and remains so until the drum perforates alleviating the pres sure and pain and leading to a discharge. This is performed under direct vision using microsuction or with a probe covered with cotton wool. If there is spreading cellulitis associated, then sys temic antibiotics should be started and flucloxacillin would be the treatment of choice. Regular analgesics help and effective pain relief can be achieved using paracetamol. This can be combined with co deine when the pain is more severe, although the evidence of benefit is not definitive. Pseudomonas infections account for two-thirds and staphylococcal are the next most common. The remaining 10% of infections are fungal and Aspergillus is the most common form. Acetic acid solution or an antibacterial/ corticosteroid combination is effective. There has been a recent study which suggests that ear drops containing corticosteroids are more effective than acetic acid drops, and that steroid and acetic acid or steroid and antibiotic drops are equally effective. Acetic acid 2% solution (EarCalm spray) has both antibacterial and antifungal effects and works by increasing the acidity of the ear canal, making it more difficult for pathogens to grow. The spray must be primed before use by pressing the actuator up and down until a fine mist is seen. The nozzle is then placed into the ear and pressed once to deliver the correct dose. While having a shower, you can do this by placing a piece of cotton wool coated in soft white paraffin. Do not use corners of towels or cotton buds to dry any water that does get in the ear canal. Try not to scratch or poke the ear canal with fingers, cotton wool buds, towels, etc. The middle ear is normally an air-containing compartment that is sealed from the outside apart from a small tube (the Eustachian tube), which connects to the back of the throat. Within the middle ear are tiny bones that transmit the sound wave vibrations of the eardrum to the inner ear. An infection typically starts with a common cold, especially in children, which leads to blockage of the Eustachian tube and fluid formation within the middle ear. Some times the infection takes off so quickly that the eardrum perforates, releasing the infected fluid. When this occurs, a discharge will also be present and be associated with considerable lessening of pain. It appears that many cases of otitis media settle spontaneously and the effect of taking antibiotics possibly only provides some benefit in symptoms after the first 24 h when symptoms are already resolving. A meta-analysis of the research done on the value of antibiotics shows the number needed to successfully treat one patient is seven. In other words, six of every seven children treated for otitis media do not need antibiotics or show no response to them. Other concerns with the use of antibiotics are increasing bacterial resistance and adverse effects such as diarrhoea, which occurs in about 10% of cases. A recent research paper suggests that it would be reasonable to delay starting antibiotics for 72h and only starting if symptoms persist at that time. If the Eustachian tube is still blocked during a flight, pain can be experienced due to the change in air pressure. This occurs because the fluid that forms in the middle ear does not drain out completely. One method of dealing with this common problem is a minor operation in which the fluid is sucked out through the eardrum. The grommet has a small hole in the middle, which allows any further fluid forming to drain from the middle ear. The grommet normally falls out within a few months and the small hole in the drum closes over. Some children are advised not to get water into the ear after the insertion of a grommet. However, this is often unnecessary and bathing and swimming can be undertaken without using plugs, al though it is sensible to avoid deep diving as water may enter the middle ear under pressure, which will impair hearing and may predis pose to infection. She and her parents have been regular customers for years and you know she recently went to Kenya on holiday. She has had antibiotics to treat it on four previous occasions during the last 3 years. She knows from experience that if she can take some antibiotics within 24 h, the ear infection will not be so bad. In the past the doctor has had trouble inserting the otoscope because the inside of her ear had been so swollen and painful. The problem causes a feeling of intense pressure inside the ear and she then has a discharge from the ear, which seems to ease the pain. Using the framework from the previous example, I can think about possible actions I could take. Is this decision supplying supplying supplying different from the one I have reached for the patient If on resolution of this infection there were exudate and debris present in the outer ear canal, she could benefit from cleaning of the ear using microsuction. She might also benefit from using an acetic acid spray, especially when she has been on holiday or swimming. Whether the pharmacist is confident about childhood problems or not the most important method of dealing with this is to listen well, not just to the presenting complaints but also to the specific concerns of the parent. Sometimes people will be more open with their concerns and some times it will be necessary to ask them about their concerns more than once. Just sharing a concern can literally diminish the perceived prob lem and make the rest of the consultation with the pharmacist more effective. Common childhood rashes Most childhood rashes are associated with self-limiting viral infec tions. They may appear as short-lived fine flat (macular) or slightly raised (papular) red spots, often on the trunk. These relatively minor illnesses occur in the first few years of life and settle without treatment. Any rash in early childhood, particularly during the first year, can be alarming and frightening for parents. Infectious diseases Chickenpox Measles Roseola infantum Fifth disease German measles Meningitis Rashes that do not blanch Chickenpox (also known as varicella) this is most common in children under 10. Sometimes the rash is preceded by a day or so of feeling unwell with a tempera ture. The rash is characteristic and only difficult to diagnose when very few spots are present. Typically it starts with small red lumps that rapidly develop into minute blisters (vesicles). The whole infection is usually over within 1 week but it may be longer and more severe in adults. After the first 2 days of this prodromal phase, small white spots (Koplik spots), like grains of salt, can be seen on the inner cheek and gums. Sometimes there are so many spots that they merge together to form large red areas. If, however, the fever persists, the cough becomes worse, or there is difficulty in breathing or earache, then medical attention should be sought as complications may be developing. Once the rash appears there is usually an improvement in symptoms, in contrast to measles, and it only lasts about 24 h. Fifth disease (erythema infectiosum) Fifth disease is another viral infection (parvovirus B19), which usually affects children. It does not often cause systemic upset but may cause fever, headache and rarely, painful joints. It particularly affects the cheeks and gives the appearance that the child has been out in a cold wind. The rash then appears on the limbs and trunk as small red spots that blanch with pressure. German measles (rubella) German measles is a viral infection that is generally very mild, its main significance being the problems caused to the fetus if the mother develops the infection in early pregnancy. The rash is preceded by mild catarrhal symptoms and enlargement of glands at the back of the neck. Meningitis Meningitis is a very serious infection that can be caused by bacterial, viral or fungal infections. The bacterial causes, which are much more serious than viral causes, include meningococcus, Haemophilus and pneumococcus infections. Meningo coccus can cause a septicaemia (infection spreading throughout the body in the blood) in addition to meningitis alone, causing a typical rash. Meningococcal septicaemia usually presents with flu-like symptoms that may rapidly worsen (see Table 8). There may be an associated rash that appears as small widespread bruises (very small bruises are called petechiae, and larger ones, ecchymoses).

Herane as the underlying pathogenic mechanisms [1, Department of Dermatology, University of Santiago der Chile, Santiago, Chile 2]. Herane sulfate and early appearence of comedones are predictors of severe or long-standing acne in this age. The differential diagnosis includes dif ferent diseases depending on the stage of infan tile acne. Very exceptionally the use of combination treatments and the addition of systemic thera pies like antibiotics are prescribed in infants and young children with inammatory lesions. The use of isotretinoin is considered in persistent nodulocystic acne susceptible to scarring or to prevent psychological sequelae.

The same investigators reported over 3,000 women, 17 % had clinical and 24 % that in 204 referred acne patients over the physiologic acne. Of these women, 41 % had age of 25, the relative risk of acne occurring late-onset acne [6]. Thus, depending on the type Hormonal stimulation of sebum 32 Adult Acne 245 been suggested, primarily by twin studies, no increases in serum androgen were that heredity plays an important role in the found [13]. Genetic factors evidence for the role of hormones in adult may determine the failure of acne-prone women with acne. There are numerous follicles to normally evolve into acne-resis series documenting elevated free testos tant follicles in early adult life [2]. In many types of acne are also inuential in adult studies, the individual serum levels of acne. Abnormal keratinization, bacterial androgens have been found to be abnor colonization, and inammation are dis mal; in other studies, individual serum cussed in detail elsewhere in this book. However, analysis of the cutane hormonally controlled is the observation of ous microora in adolescent, persistent, a clinical are of acne in the premenstrual and late-onset acne patients and controls phase of the menstrual cycle. This is perhaps documented premenstrual inammatory not surprising as acne is known to have acne ares [17]. Similarly, by elevated androgens, another hypothesis changes in the inammatory response to for the etiology of the premenstrual are is P. In most role of hormone abnormalities in adults cases, the onset of acne will occur at with these conditions [18]. These disor puberty and generally persist into early ders are discussed fully elsewhere in this adulthood.

List various nondisease states that can result in an abnormal laboratory test result. Sensitivity is the percentage of persons with the disease who are correctly identified by the test. Specificity is the percentage of persons without the disease who are correctly excluded by the test. Clinically, these concepts are important for confirming or excluding disease during screening. Albumin functions to maintain osmotic pressure in the vasculature and also serves as a transport protein. This occurs because of decreased osmotic pressure within the vasculature and resultant tissue edema. Albumin serves to transport various drugs, ions, pigments, bilirubin, and hormones. Liver (cells of the biliary tract), intestine (mucosal cells of the small intestine), placenta (pregnancy), and bone (osteoblasts) are sources of alkaline phosphatase. Any bone lesions (such as sarcoma or metastatic lesions) that produce increased osteoblastic activity will result in elevated alkaline phosphatase levels. Normal bone growth in children and adolescents will also result in alkaline phosphatase elevations. What are the two hepatic conditions that result in elevation of alkaline phosphatase concentration This obstructive process of the biliary system can result in significant enzyme elevation. How can liver versus bone-related elevations in alkaline phosphatase levels be differentiated Aminotransferases are enzymes involved in liver synthetic function and/or liver injury. Together with alkaline phosphatase and bilirubin, aminotransferase evaluation can help the clinician determine the pattern or cause of underlying liver disease. Examples include 1) skeletal muscle injury from intramuscular injection, muscle trauma with severe/prolonged exercise, polymyositis, and seizure disorder or 2) myocardial damage as seen in acute myocardial infarction. Often the degree of enzyme elevation does not correlate with the severity of disease. Chronic pancreatitis is a result of chronic alcohol abuse, hypercalcemia, hyperlipidemia, trauma, or hereditary causes. The presence of a positive result can 1) occur in normal individuals, 2) may not indicate disease, or 3) may indicate persons destined to develop disease. Jaundice is yellow discoloration of the skin because of bile deposition in the skin and sclerae. Jaundice can result from abnormal processing of bilirubin, excess bilirubin production, biliary obstruction, or liver damage. It is used clinically as an estimate of renal function along with serum creatinine levels. Almost 98% to 99% is found in bone; 1% is found in the intracellular/extracellular space. Here, bones refer to bone pain, stones to nephrolithiasis, and psychiatric overtones to confusion and altered concentration. Neuromuscular irritability occurs as a result of the decrease in the excitation threshold of neural tissue, with a resultant increase in excitability, repetitive response to a stimulus, and continued activity of the affected tissue. Within the differential white cell count (Diff), name the five white blood cell types, their percentages, and what they protect against. Neutropenia can be caused by viral infections, aplastic anemias, drugs, radiation, and leukemias. It is indicated in the diagnosis and monitoring of temporal arteritis and polymyalgia rheumatica. What are the symptomsof hypoglycemia, and what is the most common cause of this condition Symptoms and signs include weakness, sweating, tremors, tachycardia, headache, confusion, seizure, and coma. Retinopathy, neuropathy (peripheral and autonomic), nephropathy, and infections are some of the complications. Platelets are necessary for blood clotting and contribute to vascular integrity, adhesion, aggregation, and subsequent platelet plug formation. Symptoms include mild to severe hemorrhage, petechiae, purpura, epistaxis, hematuria, bruising, menorrhagia, and gingival bleeding. Most of these conditions cause platelet injury, platelet consumption, or platelet loss. This can be a primary (essential thrombocythemia), secondary (eg, leukemia, myeloma, polycythemia, splenectomy, hemorrhage, infections, or drugs), or transient process (after exercise, stress, or epinephrine injection). Clinically, thrombocytosis can cause thrombosis or bleeding or can remain asymptomatic. Routine blood testing measures only the small extracellular portion and not total body potassium. The majority of K+ (90%) is excreted by the kidneys, with the remainder lost in stool and sweat. K+ levels are influenced by acid-base status, hormone status, renal function, gastrointestinal loss, and nutritional status. Values greater than 1:80 are significant; values of 1:640 and higher can be seen in rheumatoid arthritis. Besides blood, it can be found in peritoneal, pleural, synovial, and pericardial fluid. In general, sodium affects acid-base balance, osmotic pressure balance, and nerve transmission. Despite wide variations in sodium intake, serum levels are maintained within a narrow therapeutic range. Changes in body water and salt balance are determined/monitored by serum sodium levels. Renal blood flow, carbonic anhydrase activity, aldosterone, pituitary hormones, renin, and antidiuretic hormone are important in sodium homeostasis. Confusion, muscle cramps, lethargy, anorexia, and nausea are seen with moderate hyponatremia or gradual onset of hyponatremia. There are many causes: 1) hypotonic (isovolemic, hypovolemic, or hypervolemic); 2) isotonic; or 3) hypertonic. The clinical manifestations (confusion, lethargy, seizures, and coma) relate to the degree of hyponatremia or hypernatremia and the rapidity of onset of the electrolyte disturbance. A patient with low serum sodium levels, tachycardia, hypotension, vomiting, diarrhea, and diuretic use has what form of hyponatremia This patient is volume overloaded and is suffering from hypervolemic hyponatremia. Both sodium and water are increased, but water is increased proportionally more than sodium. A 70-year-old male taking medication for hypertension and diabetes develops profound muscle weakness after 4 days of vomiting and diarrhea. Severe hemorrhage, petechiae, purpura, epistaxis, hematuria, and bruising are signs of which condition Its purposeis to test the integrity of the myelin sheath of motor (efferent fibers) and sensory (afferent fibers) portions of the peripheral nervous system. It identifies normal or abnormal physiologic findings by location and by characteristics and offers information regarding prognosis. The most common referral seen from the primary care setting is an evaluation for an entrapment neuropathy (eg, carpal tunnel syndrome or ulnar neuropathy at the elbow). The next most common referral is to differentiate between bilateral lumbosacral radiculopathies caused by spinal stenosis and peripheral polyneuropathy. They are also invaluable for diagnosing primary muscle disease, including muscle weakness that may occur as a major side effect from the pharmacologic management of hyperlipidemia (use of statin drugs). They can be extremely helpful when pain is associated with numbness, tingling, and/or weakness. It is calculated by dividing the distance between two points of stimulation by the time it took for the nerve impulse to travel between these two points. Abnormal insertional activity may be reported as increased (>200 ms reflecting acute muscle cell membrane instability) or decreased (<50 ms reflecting a loss of electrical viability of the muscle cell membrane). The spontaneous appearance of positive sharp waves and fibrillation potentials indicates an acute process of muscle cell membrane instability and may be present in neuropathic or myopathic conditions. Other abnormal spontaneous discharges include waxing and waning discharges, complex repetitive discharges and fasciculations that indicate chronicity. A normal motor unit has four phases or less (times crossing the baseline), is less than 5 mV in amplitude, is more than 5 ms and less than 16 ms in duration, and fires at a frequency of less than 10 Hz. A neuropathic motor unit may have more than four phases (polyphasic), greater than 5 mV in amplitude (larger than normal amplitude), greater than 16 ms in duration (wide duration), and/or fires faster than 10 Hz before recruitment of the next motor unit. A myopathic motor unit may be less than 300 V in amplitude (low amplitude), less than 5 ms in duration (short duration), and fire many motor units with minimal effort. A neuropathic condition would exhibit reduced motor unit recruitment along with a loss of firing voluntary motor units. When the amplitude is within normal limits, this suggests the existence of a disease process or injury of the myelin (see focal demyelinating process below). Distal Latency Amplitude Conduction Velocity Upper Limb Motor nerve (8-cm distance) <4. Radiculopathies are nerve injuries that are preganglionic (proximal to the dorsal root ganglion). In a completely severed nerve or when severe conduction block is present, voluntary motor units are absent in muscles innervated by the nerve distal to the lesion site. Most often these motor units have lower than normal amplitudes (<300 V) and short durations. Although the anterior horn cell along with its axon and neuromuscular junctions remains intact, the loss of muscle fibers results in short-duration low-amplitude motor units. The pattern of myopathic abnormalities is typically confined to the most proximal muscles of the limbs and trunk and is symmetric. The surviving motor units have larger than normal amplitudes (>5 mV) and wide durations because they sprout to capture denervated muscle fibers within their territory (reinnervation). The pattern of abnormalities is typically confined to a specific peripheral nerve distribution (root, plexus, nerve) or may be distal and symmetric when disease is present. This is caused by pathologic changes in the acetylcholine receptors on the postsynaptic side of the neuromuscular junction that block the transmission process and cause motor weakness.
