In most instances after being informed of such risks erectile dysfunction and diabetes type 2 20mg levitra professional fast delivery, patients will prefer alternative antibiotics which have similar coverage and less side effects doctor for erectile dysfunction in chennai cheap levitra professional 20mg visa. In most instances erectile dysfunction what kind of doctor generic 20 mg levitra professional overnight delivery, other antibiotics can provide the same coverage with less risk and similar cost erectile dysfunction treatment prostate cancer safe 20mg levitra professional. However erectile dysfunction drugs over the counter buy levitra professional 20mg line, in patients with allergies to other antibiotics erectile dysfunction latest medicine buy genuine levitra professional line, sulfonamides may be useful. Their main indication is in resistant urinary tract infections, but their broad spectrum makes them effective in other conditions. Their use is limited in pediatrics since they are currently contraindicated in children and pregnant women, because these drugs have impaired bone growth in laboratory animals. Carbapenems this new class of antibiotics target bacterial cell wall synthesis by inhibiting the transpeptidase enzymes required for peptidoglycan cross-linking. These drugs have not been used commonly in pediatrics since they are most commonly used in highly resistant adult infections. They also cover many atypical organisms such as Mycoplasma, Chlamydia, Legionella, Bordetella, Yersinia, Campylobacter, and Tularemia. Erythromycin estolate gets higher tissue levels and is commonly recommended for pertussis. Newer and more expensive erythromycins such as azithromycin and clarithromycin have broader coverage, less side effects and more convenient dosing. Tetracycline use is discouraged in children because it causes staining of teeth, hypoplasia of dental enamel, and abnormal bone growth in children. Vancomycin can also be given orally for pseudomembranous colitis caused by Clostridium difficile. Clindamycin is a useful for the outpatient treatment of cellulitis and other infections commonly caused by group A strep and Staph aureus. Many clinicians treat cellulitis and other suspected outpatient Staph aureus conditions with clindamycin instead of cephalosporins since resistance to cephalosporins is too frequent. Clindamycin is also used for coverage of anaerobes including Bacteroides fragilis. Chloramphenicol is used infrequently because it has the potential to cause irreversible bone marrow suppression. It more commonly causes reversible bone marrow suppression which is not nearly as severe. Chloramphenicol has the unusual property of attaining high serum levels from oral administration. Cephalosporins and vancomycin have largely replaced these older drugs to treat meningitis. Metronidazole (Flagyl) is a anti-parasitic anti-amebic drug, but it also has nearly complete coverage of anaerobes. Thus, when 100% anaerobe coverage is required, the options include metronidazole, clindamycin or chloramphenicol. The broad spectrum penicillins in combination with clavulanate or sulbactam may also cover anaerobes sufficiently. What empiric antibiotic(s) could be used to cover the organisms in the above question? The Merck Manual of Diagnosis and Therapy, Seventeenth Edition, Centennial Edition. How do these cephalosporins differ from each other and what characteristic places them in a given generation? Similarly, searches for fifth and sixth generation cephalosporin yields some articles. If I was a slick marketer of drugs, I would simply call my new cephalosporin "Tenth Generation" and almost everyone would buy it. However, what specific characteristic of the cephalosporin makes it clinically useful over other cephalosporins? If the drug was a tenth generation cephalosporin, but it had no clinical advantage over an existing third generation cephalosporin, then there is no need for a such a tenth generation cephalosporin. The generation is not nearly as important as the specific property of the cephalosporin which makes it clinically useful over another cephalosporin. Bacterial meningitis: Pneumococcus, meningococcus, Haemophilus influenzae type B (HiB). For osteomyelitis, we could cover the Staph aureus with an anti-Staph aureus penicillin such as oxacillin, nafcillin or methicillin or a first generation cephalosporin such as cefazolin. Although there is a good chance the patient will respond, in 25% to 30% of cases, this treatment will fail and the patient will suffer the consequences of inadequate treatment which would include: death from sepsis, Staph pneumonia, spread of the osteomyelitis, chronic osteomyelitis requiring an amputation, etc. Although trimethoprim/sulfamethoxazole (Bactrim or Septra) is commonly recommended because of its broad coverage for this indication, this drug causes Stevens-Johnson syndrome more commonly than others. If the parents accept this increased risk, then this Page - 181 should be documented on the chart. Most parents are not willing to accept this increased risk since other antibiotics are available. Amoxicillin will probably work, but there is a high frequency of resistance which is generally not a probably for simple cystitis, but in a febrile 18 month old, there may be some degree of pyelonephritis as well. Thus, an acceptable answer here would also be a first generation cephalosporin such as cephalexin. Additionally, since most patients have drug plans, the difference may be negligible. If both medications are efficacious, perhaps it is best to discuss these differences with the patient and give them some input in the decision. He has had coughing and runny nose for about 5 days that has been treated with an over-the-counter cold medicine. He also has a low-grade fever of about 101 degrees axillary for the past two days. His past medical history is significant for ear infections in the past, with his last otitis media being 5 months ago treated with amoxicillin. It is estimated that otitis media comprises 23% of all office visits in the first year of life, and 40% at four to five years when these children start Kindergarten. The middle ear is a gas filled cavity in the petrous part of the temporal bone between the external auditory canal and the inner ear. Therefore, factors hindering the movement of these ossicles, such as pus or fluid in the middle ear, will adversely affect hearing. The eustachian tube allows for ventilation and clearance of fluid from the middle ear. Also, the angle of the tensor veli palatini muscle to the cartilage around the tube is variable, compared to being stable in the adult. The significance of these characteristics is that there is a greater likelihood that nasopharyngeal secretions can reflux or insufflate into the middle ear, and that clearance of the middle ear cavity of these secretions is decreased (2). These differences are the reason why there are more middle ear infections in the infant compared to the adult and older child. Otitis media is common in infants and young children with the peak age being between 6 to 18 months of age. This is due not only to anatomical factors, but immunologic as well since these children still lack many protective antibodies against viral and bacterial organisms. Also, babies are breast fed while in a vertical or semi-reclining position, compared to some babies who may be bottle-fed while in a horizontal position. The presence of cerumen and uncooperative and frightened patients complicate this. It should be noted, although controversial, that a tympanic membrane may become red in a crying child (4). This chapter will focus on two types of otitis media, namely acute otitis media and otitis media with effusion. Older children may complain of a "plugged" feeling or "popping" in their ears, which is usually bilateral. It is important to distinguish between the two diseases because the management of each is different, however, it is not easily done. If severe otalgia is present, then analgesia becomes a major therapeutic consideration. Although Auralgan otic is used for pain relief, one should be aware of allergic reactions and to make sure there is no perforation. The management of otitis media is one of many controversial subjects in pediatrics. The three most common organisms are Streptococcus pneumoniae, non-typable Haemophilus influenzae, and Moraxella catarrhalis. Other less common organisms are Streptococcus pyogenes, Staphylococcus aureus, gram negative enteric bacteria, and anaerobes (5). The choice of antibiotic is dependent on efficacy, palatability, side effects, convenience of dosing, and cost. For this reason, it is recommended that the dose of amoxicillin be increased from 40-50 mg/kg/day to 80-90 mg/kg/day in two to three divided doses. However, children who are at low risk for resistant organisms may be treated with the lower dose of amoxicillin, being 40-50 mg/kg/day. Risk factors include young age (less than 2 years), recent antibiotic use (within the last month), and day care attendance (4). In patients who are allergic to beta-lactam antibiotics, macrolides, like erythromycin plus sulfisoxazole, azithromycin, or clarithromycin, and trimethoprim-sulfamethoxazole may be used. The duration for treatment is 10 days, although azithromycin, cefpodoxime, and cefdinir are now approved for 5 days, and a single dose of intramuscular ceftriaxone is as effective as a 10-day course of amoxicillin. Also recently, azithromycin has been approved for a 30 mg/kg one time dose, or 10 mg/kg dose for three days. Other drugs that are recommended are cefprozil, ceftibuten, loracarbef, and clindamycin (6). Persistent otalgia, fever, and other systemic symptoms past 72 hours should be reevaluated. At times, tympanocentesis or myringotomy is necessary for resistant cases, at which time a culture can also be obtained. Follow-up visits are recommended 10-14 days later to determine the need for further antimicrobial treatment. Although a middle ear effusion may be present, an inflamed eardrum or persistent systemic symptoms at this follow-up visit may warrant changing the antibiotic therapy or performing a myringotomy/tympanocentesis. It is estimated that 30-70% of children will have a middle ear effusion 10-14 days later, and that without treatment, 6-26% will have a persistent middle ear effusion after 3 months, with the mean of resolution being about 23 days. Medications that have been studied are decongestants, antihistamines, oral corticosteroids, and antibiotics. The only drugs proved efficacious are oral corticosteroids and antibiotics; however, it is felt that the side effects from oral corticosteroids outweigh its benefits. Other antibiotics that have been recommended are cefaclor, erythromycin-sulfisoxazole, and ceftibuten, although these are either just as efficacious or less so than amoxicillin. If antibiotic therapy fails, then myringotomy with tympanostomy tube placement or myringotomy and adenoidectomy are recommended as the next step. Only ofloxacin otic solution is approved in children with acute otitis media with tympanostomy tubes or chronic suppurative otitis media with perforation (8). Not only do we treat otitis media for symptomatic relief, but also to prevent its complications. Fortunately, because we live in the antibiotic era, these complications are rarely seen. Only in a few children does medical therapy fail, and more aggressive measures are needed, such as myringotomy and tympanostomy tubes. As the humidity in the outer ear increases, the stratum corneum in the cartilaginous portion of the ear absorbs water, which results in edema. Edema blocks the pilosebaceous units in the ear, thereby decreasing the excretion of cerumen. A decrease in cerumen causes an increase in the pH of the external ear, in addition to decreasing its water repelling covering. The exposed skin becomes susceptible to maceration and the higher pH becomes a favorable environment for bacteria such as Pseudomonas. Bacteria can then penetrate through the dermis after superficial breakdown or through minor trauma such as with cotton applicators. The most common organisms cultured in otitis externa are Pseudomonas and Staphylococcus aureus. Other organisms that can be cultured are Enterobacter aerogenes, Proteus mirabilis, Klebsiella pneumoniae, streptococci, coagulase-negative staphylococci, diphtheroids, and fungi such as Aspergillus and Candida. Symptoms initially include pruritus and aural fullness, which then progresses to ear pain that may be severe and out of proportion to its appearance. Purulent otorrhea and hearing loss from edema of the canal may be present as well. Examination shows an inflamed and erythematous cartilaginous canal, with variable involvement of the bony canal. Although the tympanic membrane is not affected, it and the medial portion of the canal can become involved and often look granular. When this happens, pneumatic otoscopy is needed to rule out concomitant otitis media. Tender and palpable lymph nodes may be present in the periauricular Page - 183 and preauricular areas. Treatment includes the use of ototopical drops, such as a combination of polymyxin B, neomycin, and hydrocortisone (Cortisporin otic). Polymyxin B is active against gram negative bacilli such as Pseudomonas, neomycin is active against gram positive organisms and some gram negatives especially Proteus, and the corticosteroid reduces inflammation and edema. Fluoroquinolones are a new class of antibiotics for otitis externa; ofloxacin and ciprofloxacin are both currently available. If there is a lot of fluid drainage, it may be preferable to wick out most of the fluid prior to instilling the drops.

International Centre for Eye Health, London School of Hygiene & Tropical Medicine, and Department of Ophthalmology, Kilimanjaro Christian Medical Centre, Moshi - Tanzania 26. Caribbean Association of Ophthalmic Technical Personnel represented by Krystal Henry, Krystal Lovell-Yarde and Marilyn Watkins-Ramdin from Barbados West Indies 6 Special thanks to our peer reviewers and assistants whose involvement and support behind the scenes has also been invaluable 1. The Editor Heather Machin builds upon the first edition of the manual and the Ophthalmic Nursing Series in the Community Eye Health Journal. She incorporates the expertise of more than 33 other authors and her own widespread international experience to produce an up to date, comprehensive, professional and very practical manual for all eye care professionals. The manual covers the preparation of patients undergoing eye surgery, the nursing aspects of major eye operations, and the reception and postoperative care of patients undergoing eye surgery. Emphasis is given to the provision of cataract surgery but other conditions covered are glaucoma, diabetic retinopathy, trichiasis, ptyergium as well as sections on corneal, oculo-plastics, vitreoretinal surgery and eye surgery in children. There are excellent practical chapters describing the care and use of eye surgical equipment and instruments as well as the appropriate sterilisation techniques and an emphasis on safety. This is an essential practical manual for Eye Health Professionals working in Operating Theatres in low and middle income countries. In the context of eye care, this manual provides the knowledge that leads to good care. It arms the ophthalmic team with important information and skills required to enhance their ability to care for patients with eye problems in a surgical environment. The special challenges of working on an organ so small and so complex is also important to understand, and successful surgery can recover both lost sight, and prevent sight loss in others. Therefore, it is important that everyone on the team is working towards the success of that surgery. It is about the whole process - from the presentation of the patient, to the prioritisation of their problem and diagnosis. It is also about the environment in which surgery is undertaken along with safety and cleanliness; the instruments used and the care of the patient and those providing the care. Just as important is knowledge of infection prevention and control, equipment management, instrumentation and the management of the supply chain and the people involved in the service. By working through this manual, members of the ophthalmic team will be provided with a working knowledge of ophthalmology and the importance of providing individualised and effective care to their patients. Little did they know at that time, the text would become a staple training tool for many nurses and technicians around the world, who would come to rely on its teaching as the basis of their daily practice. And so, I began the journey to find out what we could do about it as a global community. Emphasising responsible practice, unity and equitable input, the aim was to ensure that this text truly reflects team integration, empowerment and progression, and the degree of success needed in health systems of today. We also made the decision to engage an extensive range of professionals to ensure the text could be used in a wide range of settings throughout the world. If developed effectively, systems can support and empower professionals at all levels and ensure services are followed through for the betterment of the patient and those working in the system. Those involved in this edition have worked to integrate these key elements alongside original aspects from edition one, to provide teaching on; daily management, management of self, understanding common eye conditions requiring surgical intervention, how to work within the operating theatre facility, and how to safely care for the patient. For example hand washing, completing documentation and working safely, can take place regardless of the sector, work environment and level of resource. The text can also be utilised by existing professionals requiring a refresher, and those new to the profession. It also provides an introduction to non-medically-trained development professionals and support staff who may find themselves involved in ophthalmic or operating theatre programs or organisations. I would like to take this opportunity to thank the original authors, the current contributors who adapted and up-dated the original text, all the peer reviewers and supporters, and the team at the Community Eye Health Journal, who volunteered their time and expertise towards edition two. It has been a true global collaborative effort and one that I have personally enjoyed being a part of. I have learnt a great deal from their participation, knowledge and dedication and could not have achieved it without them. Finally, if you or your organisation has found this text useful, then we would love to hear from you. Knowing if it has changed the outcomes of just one patient or taught one new technique or improved the services in one facility or team, means a great deal to those involved. Contributors: David Lewis, Heather Machin and Babar Qureshi Section 1: Something everyone should know 10 No matter where a nurse or technician works, or what type of facility they are working in - be it a public, private or university hospital, day surgery, mobile clinic, or community health department, or if they live in a high or low resource location, or in the city or the country - there are some things which all nurses and technicians need to know and be mindful of. This section will outline important points regarding professionalism, and taking care of ourselves. It will conclude with an exploration of the current global initiatives for implementation into routine practice. Professionalism Professionalism includes more than just having a title or a position in the organisation. It is about the essential drive and care that professionals have for patients and other members of their team. Professionalism is an outward demonstration of why we became an ophthalmic nurse or ophthalmic technician. Caring for Ourselves Healthcare professionals can often spend a lot of time caring for others that they forget to care for themselves. This could put their own health and safety at risk and could lead to a short-term or permanent inability to do their job (through injury or mental exhaustion). In the worst case scenario, this could result in a loss of income to support their family. A lot of healthcare is related to timemanagement, for example, when working in a ward, medication needs to be administered at a certain time - based on a doctors prescribed order. If the nurse is late to work (or late back from a break) and a medication is not given on time, the patient may be placed at risk. Many countries advocate for a regular eye check-up every 1 or 2 years, or more frequently if there is a known issue. It is also an opportunity to set a good example to the patients with preventative check-ups.

For patients who present early impotence definition inability purchase levitra professional once a day, radiographic studies must look for evidence of air trapping erectile dysfunction treatment singapore buy levitra professional toronto. However erectile dysfunction pump purchase 20mg levitra professional free shipping, many foreign body aspirations involve both main stem bronchi or the foreign body is in the trachea erectile dysfunction uk cheap levitra professional express. If the expiratory view looks the same as the inspiratory view icd 9 code for erectile dysfunction due to medication cheap levitra professional online, this implies bilateral air trapping impotence zinc 20 mg levitra professional amex. Expiratory views rely on timing, so these are sometimes deceiving (an "expiratory view" could have been really taken during inspiration). In a lateral decubitus view, the mediastinum should shift downward toward the dependent side. Thus, if a decubitus view looks the same as an upright inspiratory view, this suggests air trapping on the dependent side. If the patient presents in the first clinical phase, the family and/or health care professional should be advised to follow the recommendations of the American Academy of Pediatrics and American Heart Association (7). Unless there is a complete airway obstruction, spontaneous coughing and respiration should be the only treatment encouraged. Blind finger sweeps should never be performed in infants or children since this may push the foreign body further downward into the airway. Infants with complete airway obstruction should have back blows and chest thrusts performed while children with complete airway obstruction should have abdominal thrusts performed in either the supine position or by the Heimlich maneuver. Once the patient is brought to the hospital, the patient will require rigid bronchoscopy for visualization of the airway and removal of the foreign body. Flexible bronchoscopy does not have a role in this situation because it is not the optimal tool for control of the foreign body or the safety of the patient during the removal procedure. The other situation in which patients commonly seek medical attention is usually the third clinical phase. At this point in time, clinical suspicion based on the history, exam, and ancillary studies must be used to determine the appropriate course of action. In many such instances, a foreign body is not suspected and the foreign body remains untreated. Such patients return with "recurrent pneumonia" which is actually a pneumonia or atelectasis which has never resolved because the foreign body is still there. If foreign body aspiration is suspected in this phase, the patient should undergo direct airway visualization by bronchoscopy (flexible or rigid). Even if the patient has expectorated a foreign body, direct visualization is recommended to ensure there are no additional foreign bodies present and to determine if there is any compromise of the airway from inflammation. If there is airway edema and/or inflammation present on direct visualization, a short course of oral corticosteroids may be useful. Complications arising from foreign body aspiration depend on the location and type of foreign body aspirated (organic vs. If the foreign body is successfully removed within 24 hours of the incident, the complication rate is very low. However, the longer the foreign body remains in the airways, the more likely inflammation and thus, complications will occur. Potential complications include: bronchial stenosis, bronchiectasis, lung abscess, tissue erosion/perforation, and pneumomediastinum or pneumothorax. True/False: Foreign body aspiration is sufficiently uncommon that it need not be considered in a patient with a chronic cough. True/False: Aspirated foreign bodies in children are more likely to be in the right main-stem bronchus than the left main-stem bronchus. What physical exam sign/symptom is most worrisome in terms of degree of airway compromise? Tracheobronchial Foreign Bodies: Presentation and Management in Children and Adults. May last minutes to months depending on location, type, and ease of movement of the foreign body. Organic material is worse to aspirate because it will cause a more intense inflammatory response, thereby increasing the risk for complications. Additionally, most organic material is non-radiopaque making it more difficult to visualize. A blind finger sweep may reposition the foreign body causing a complete airway obstruction. Whenever a choking episode occurs while a young child is eating nuts, the risk of foreign body aspiration is high. The cough improved but did not clear with bronchodilators and an aggressive short course of oral corticosteroids which were instituted for suspected asthma. The symptoms had worsened again after the bronchodilator and steroid trial was discontinued. Review of systems reveals a slowing of growth from the 4 month routine well child visit to present. There is no family history of any respiratory disease, chronic or serious medical conditions. There are mild subcostal retractions, but no intercostal or supraclavicular retractions are seen. His abdomen is soft, non-distended with normal bowel sounds and no hepatosplenomegaly. His improvement over the next three days is gradual, and his chest radiograph still shows an interstitial pattern. The bronchoalveolar lavage demonstrates a large number of hemosiderin-laden macrophages. His subsequent chest radiograph clears with only persisting streaky consolidations. Any bleeding from or into the lung will lead to hemosiderin deposits in the lung macrophages. It is a complex topic, covering a spectrum of different conditions and disease states. It can be from pulmonary (lower pressure) or bronchial circulation (higher pressure). The following table categorizes the etiologies of Pulmonary Hemosiderosis in children from the standpoint of whether the lung insult is primary or secondary: 1. Pulmonary vascular disease including cardiac disease, pulmonary hypertension and arteriovenous malformations. Generalized bleeding disorders, including purpuric syndromes and coagulopathies associated with sepsis. Bleeding can come from inherited or acquired weakness, inflammation or congestion of pulmonary blood vessels; immune reactions or antigen-antibody complex deposition in the lung; invasive or chronic infections, or toxic reactions. Regardless of the, any blood cells in the alveoli, airways or parenchyma, are broken down and the hemoglobin is ingested by local macrophages. Once ingested, the hemoglobin is converted to hemosiderin by lysosomal degradation. It may also activate the local macrophages, followed by an inflammatory cascade, including the recruitment of cells and production of cytokines. These events can produce all types of lung disease, pulmonary consolidations, and lymphadenopathy. Obstructive disease can be seen as the airways narrow with an increase in edema, mucus production and shedding of epithelial cells into the airway. Bronchospasm (the contraction of smooth muscle surrounding the airways) can be seen. Chronic accumulation of fibrin and collagen deposits can lead to pulmonary fibrosis with decreased pulmonary compliance. Pulmonary hemosiderosis is an uncommon finding, but the true incidence is unknown. The classic triad of findings includes pulmonary infiltrates, iron deficiency anemia and hemoptysis (although hemoptysis is seen less commonly in children). When present, complaints include fever, pallor, dyspnea, cough, exercise intolerance and growth failure. Common findings are, tachypnea, tachycardia, cyanosis, clubbing, fine or coarse crackles, wheezing, and hypoxemia. The radiographic appearance may vary depending on the degree of involvement and chronicity. Plain film chest radiographs may range from normal to demonstrating focal lymphadenopathy or consolidations, or extensive bilateral interstitial disease. Pulmonary function testing may demonstrate an obstructive, restrictive or mixed pattern. Infectious pneumonia, bronchitis, aspiration, asthma and cystic fibrosis are more commonly seen with many of the same complaints and findings. While a bronchoalveolar lavage finding of a large number of hemosiderin-laden macrophages is diagnostic, it is not the end of the evaluation. Some experts advocate a lung biopsy for all patients, to include immunofluorescence and electron microscopy studies. Each patient should have supportive measures as appropriate to their presentation, including supplemental oxygen, blood transfusion, and antibiotics for cases of secondary infection or suspected infection. Diet restriction, especially for those found to have serum precipitins to milk products, is essential. Corticosteroids are the mainstay, but there is no study comparing the dosing strategy. Other immunosuppressive agents have been used in an attempt to reduce the prolonged corticosteroid effects, including azathioprine, chloroquine and cyclophosphamide. Close monitoring should include growth, oxygen saturation monitoring, hemoglobin and iron studies, chest radiographs, pulmonary function testing (if old enough), and renal function studies throughout recovery. Reinstitution of aggressive corticosteroid or immunosuppressive therapy is typical for breakthrough exacerbations. More recent reports suggest an improvement in this statistic with more aggressive management (8,9). Additionally, newer technology has provided the means for more extensive evaluation, facilitating specific diagnostic determination. Although scarring and fibrosis may be permanent, full compensation is possible, especially in younger patients. Which of the following is not part of the classic triad of symptoms seen in pulmonary hemosiderosis? True/False: Lung biopsy is the diagnostic test of choice for idiopathic pulmonary hemosiderosis. Hypercarbia is not usually seen because compensatory mechanisms usually overcome the problems of reduced gas exchange by increasing minute ventilation (either by increasing rate or depth of ventilation). It is one scheme to help identify the etiology for a condition with numerous causes. Treatment is more likely to be successful after identifying and treating the primary cause. Bronchospasm, edema, and mucus can narrow the airway causing obstructive disease similar to asthma. Chronic inflammation can increase interstitial fibrin and collagen deposits which then reduce compliance resulting in giving restrictive disease. The classic triad is iron deficiency anemia, pulmonary infiltrates and hemoptysis, although hemoptysis is seen less commonly in children. Pathology from lung biopsy is seldom diagnostic alone and can only be interpreted in light of the other information. There are no other associated symptoms including muscle weakness, cyanosis, hemoptysis, chest pain or dizziness. She is a pleasant, comfortable, alert, well-developed, well-nourished 5 year old who is non-toxic and in no acute distress. Her respiratory exam shows moderate tachypnea with normal chest percussion and symmetrical chest movements. Her abdomen is soft and non-tender, but notable for hepatomegaly with the inferior liver margin extending 4 cm below the right costal margin. An echocardiogram shows a dilated right atrium and right ventricle consistent with volume overload and 2 aberrant veins draining 70% of the pulmonary venous return into the vena cava instead of the left atrium. A cardiac catheterization is performed to determine the pressure in the left atrium, which is found to be elevated. She is diagnosed with pneumonia and scimitar syndrome consisting of 2 anomalous pulmonary veins draining into the vena cava and a large systemic artery 1. Scimitar Syndrome (Partial Anomalous Pulmonary Venous Return): Normal pulmonary venous circulation carries oxygenated blood from the alveolar capillaries to the left side of the heart for systemic distribution. In the Scimitar syndrome (approximately 1-3 per 100,000 births), an anomalous vein connects between the pulmonary venous circulation and systemic venous circulation which creates a left-to-right shunt that is determined by: 1) size and number of abnormal draining veins, 2) the source of venous blood flow. The anomalous venous connections and associated malformations are almost exclusively right-sided, with only a few reports of leftsided occurrence. The syndrome is composed of findings of: 1) An anomalous right pulmonary venous connection to the systemic venous circulation either above or below the diaphragm, most commonly to the inferior vena cava. Other findings may include: a) Abnormal lobulation of the lung, b) Horseshoe lung, and c) Accessory hemidiaphragm. The abnormal drainage of blood in the lungs can overload the right atrium and ventricle as well as decrease the preload for the left ventricle. Additionally, flow from the perfusing artery stemming from the aorta may be greater than the outflow from anomalous veins, leading to increased left-sided volume loading, accelerated pulmonary hypertension, and associated symptoms of cardiac failure (2). This is not normally the case, as most symptoms arise from increased volume loading of the right heart (due to increased venous return) and pulmonary artery pressure is generally normal (3). The most common early clinical manifestation is an increased frequency of pulmonary infections.

If you think "obstetrics erectile dysfunction kegel exercises safe 20mg levitra professional," you will instantly know which letter pregnancy codes begin with erectile dysfunction drugs in homeopathy buy 20 mg levitra professional visa. A section is a group of three-digit categories that represent a group of conditions or related conditions impotence 27 years old buy levitra professional overnight delivery. A three-character category is a code that represents a single condition or disease erectile dysfunction psychological purchase levitra professional 20 mg without prescription. Italicized codes are to be sequenced according to specific coding instructions in the Tabular List erectile dysfunction caused by surgery discount 20 mg levitra professional fast delivery, such as "Code first erectile dysfunction patient.co.uk doctor order levitra professional 20 mg free shipping. Other subterms or Excludes notes may provide hints as to what the other classifications may be. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition. When an Excludes2 note appears under a code, it is acceptable to use both the code and the Excludes2 code together. For example, the first Excludes2 note in Chapter 1 indicates that the infectious and parasitic disease does not include a carrier or suspected carrier of infectious disease as shown in. Code first/use additional code the "Code first" and "Use additional code" notations indicate etiology/manifestation paired codes. Certain conditions have both an underlying etiology and multiple body system manifestations. For such conditions, the I-10 has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. For example, the Code first notation at D77 directs the coder to first report the underlying disease, such as illustrated in. The default code represents that condition that is most commonly associated with the main term, or is the unspecified code for the condition. If a condition is documented in a medical record (for example, appendicitis) without any additional information, such as acute or chronic, the default code should be assigned. For the initial encounter of a sprain of an unspecified acromioclavicular joint, the correct code, as shown in. The 7th character now and in the future will identify whether the disorder is of the right or left knee. Diagnostic coding and reporting guidelines for outpatient services these coding guidelines for outpatient diagnoses have been approved for use by hospitals/providers in coding and reporting hospital-based outpatient services and provider-based office visits. Information about the correct sequence to use in finding a code is also described in Section I. Never begin searching initially in the Tabular List as this will lead to coding errors. Examples Select the first-listed diagnosis Established 50-year-old patient was seen in the clinic for acute bronchitis. Established patient is a 75-year-old male complaining of substernal chest pain, which is relieved with rest. Lab work revealed a urinary tract infection and blood glucose was within normal limits. First-listed diagnosis: (Answers are located in Appendix B) Most physicians will document the "chief complaint" of the patient for each encounter in the medical record. For example, a patient presents with a chief complaint of a backache, and after examination, the physician determines the patient has an acute kidney infection due to Escherichia coli. The reason for these visits can be reported as first-listed codes using codes from Chapter 21: Z02. Initial office visit, 30-year-old woman complains of fatigue, abnormal weight gain, and constipation. In this case the only reportable diagnoses are symptom codes as no specific diagnosis has been confirmed during this visit. Follow-up office visit, 30-year-old woman with continued complaints of fatigue, weight gain, and constipation. Lab results confirm that patient has hypothyroidism and she was started on Synthroid. Follow-up office visit, 30-year-old woman is seen following her repeat thyroid function studies and her hypothyroidism has responded to the Synthroid. Patient was scheduled for small-bowel xrays and colonoscopy and will be seen in the office following those outpatient procedures. Codes:, 2 Follow-up office visit for a 28-year-old male with recent colonoscopy with biopsy and small bowel x-rays. Code: 3 Initial office visit for 55-year-old male with fatigue and jaundice. Codes:, 4 Follow-up office visit for 55-year-old male with jaundice and fatigue. Outpatient surgery When a patient presents for outpatient surgery (same day surgery), code the reason for the surgery as the first-listed diagnosis (reason for the encounter), even if the surgery is not performed due to a contraindication. She was seen by her physician and her surgery was canceled because of an exacerbation of her asthma. First-listed diagnosis: 3 A patient was admitted as an outpatient for a cystoscopy for hematuria. The Guidelines state that it is acceptable to use any of the codes throughout the entire Tabular List to identify the reason(s) for an outpatient visit including the use of Z codes. This guideline assures data integrity by promoting accurate I-10 diagnosis codes that are supported by documentation in the health record. According to Guideline D, it is acceptable for symptoms and signs to be reported if no definitive diagnosis has been established by the provider. Chapter 18 of the I-10 contains codes (R00-R99) for most of these symptom or sign codes, but there are other such codes throughout the I-10. Codes that describe symptoms and signs Codes that describe symptoms and signs, as opposed to diagnoses, are acceptable for reporting purposes when a diagnosis has not been established (confirmed) by the provider. Sometimes, important information contributing to the care of the patient is not an illness. Sometimes the Z code will be the first-listed code, and sometimes the Z code will be a supplemental code. Although the patient has been symptom-free for seven years, her history of breast cancer will contribute to the diagnostic path the physician chooses. John went camping last month in the Rockies with several friends who now have been diagnosed with Giardia from drinking from the mountain stream. The laboratory results indicate that he has been infected with Giardia lamblia and is prescribed a 10-day course of Flagyl. The Factors Influencing Health Status and Contact with Health Services codes (Z00-Z99) are provided to deal with occasions when circumstances other than a disease or injury are recorded as diagnosis or problems. Chapter 21: factors influencing health status and contact with health services (Z00-Z99) Note: the chapter specific guidelines provide additional information about the use of Z codes for specified encounters. Use of Z codes in any healthcare setting Z codes are for use in any healthcare setting. Categories of Z Codes 1) Contact/Exposure Category Z20 indicates contact with, and suspected exposure to , communicable diseases. Procedure codes are required to identify the actual administration of the injection and the type(s) of immunizations given. According to the Guidelines, which category code would you reference to report inoculations and vaccinations? This includes such things as the presence of prosthetic or mechanical devices resulting from past treatment. A status code is informative, because the status may affect the course of treatment and its outcome. A status code should not be used with a diagnosis code from one of the body system chapters, if the diagnosis code includes the information provided by the status code. For encounters for weaning from a mechanical ventilator, assign a code from subcategory J96. The status Z codes/categories are: Z14 Genetic carrier Genetic carrier status indicates that a person carries a gene, associated with a particular disease, which may be passed to offspring who may develop that disease. If the patient has the condition to which he/she is susceptible, and that condition is the reason for the encounter, the code for the current condition should be sequenced first. Additional codes should be assigned for any applicable family or personal history. Resistance to antimicrobial drugs this code indicates that a patient has a condition that is resistant to antimicrobial drug treatment. Carrier of infectious disease Carrier status indicates that a person harbors the specific organisms of a disease without manifest symptoms and is capable of transmitting the infection. Do not resuscitate this code may be used when it is documented by the provider that a patient is on do not resuscitate status at any time during the stay. This code should not be assigned for the encounter in which the transplanted organ is removed. The External Cause Index is located after the Table of Drugs and Chemicals in the I-10. The index classifies environmental events (tornadoes, floods), circumstances, and other conditions as the cause of injury and other adverse effects alphabetically. The main terms in the code index usually represent the type of accident or violence. When an external cause code is reported, it is reported in addition to an injury code from the Tabular List of the I-10. When a person who is currently not sick encounters the health services for some specific purpose, such as to act as donor of an organ or tissue, to receive a preventive vaccination, or to discuss a problem that is in itself not a disease or injury. A patient with a known disease or injury receives health services for specific treatment of the disease or injury. If there is any question regarding the current status of the disease, check with the physician. You may also want to offer some physician education regarding the documentation of past history of diseases. Observation stay When a patient is admitted for observation for a medical condition, assign a code for the medical condition as the first-listed diagnosis. When a patient presents for outpatient surgery and develops complications requiring admission to observation, code the reason for the surgery as the first reported diagnosis (reason for the encounter), followed by codes for the complications as secondary diagnoses. These observation codes are reported only as the first-listed diagnosis for medical observation for suspected conditions and conditions ruled out. Other codes may be reported in addition to the observation codes but only when that condition or conditions are unrelated to the reason for the observation. For example, a patient admitted for observation for suspected exposure to anthrax (Z03. If the patient also has primary hypertension (I10), the hypertension may be reported as it is unrelated to the anthrax exposure and observation. The I-10 code to report observation for suspected exposure to anthrax, ruled out, is. If the newborn has signs or symptoms of a suspected problem, you would report the signs or symptoms and not a code from the P00-P04 observation codes. Code: b the second code is for the abrasion to the right upper arm. Code: 3 A 35-year-old female patient was admitted to observation for severe nausea and vomiting following diagnostic laparoscopy for pelvic pain. First-listed diagnosis: 5 Patient was admitted for observation because of urinary retention following a Dilation and Curettage (D&C) for post-menopausal bleeding. First-listed diagnosis: (Answers are located in Appendix B) First-listed diagnosis and coexisting conditions You have already had practice at selecting the first-listed diagnosis, and you know that it is possible for the first-listed diagnosis to be a symptom. Medications that the patient takes for the arthritis were reviewed to see if they could be the cause of the palpitations. First-listed diagnosis: Code: Other diagnosis: Code: 2 Patient is an established patient with memory loss. Uncertain diagnosis Do not code diagnoses documented as "probable", "suspected," "questionable," "rule out," or "working diagnosis" or other similar terms indicating uncertainty. Please note: this differs from the coding practices used by shortterm, acute care, long-term care and psychiatric hospitals. Reported diagnosis and code: Reported diagnosis and code: Diagnosis not reported: 3 Office consultation for a new patient with amenorrhea and galactorrhea. Reported diagnosis and code: Diagnosis not reported: (Answers are located in Appendix B) Chronic diseases If a patient has a chronic condition that is treated on an ongoing basis, you can report the condition as many times as the patient receives care or treatment for the condition. Examples Chronic diseases An established patient is seen for equal management of mild, intermittent, uncomplicated asthma and type 2 diabetes. An established patient is seen for management of hypertension and congestive heart failure. He continues to smoke 1 package of cigarettes per day, against repeated medical advice. Patients receiving diagnostic services only For patients receiving diagnostic services only during an encounter/visit, sequence first the diagnosis, condition, problem, or other reason for encounter/visit shown in the medical record to be chiefly responsible for the outpatient services provided during the encounter/visit. For encounters for routine laboratory/radiology testing in the absence of any signs, symptoms, or associated diagnosis, assign Z01. If routine testing is performed during the same encounter as a test to evaluate a sign, symptom, or diagnosis, it is appropriate to assign both the Z code and the code describing the reason for the non-routine test. Code: 2 Chris, a 43-year-old male patient, presents for his annual examination. Patients receiving therapeutic services only For patients receiving therapeutic services only during an encounter/visit, sequence first the diagnosis, condition, problem, or other reason for encounter/visit shown in the medical record to be chiefly responsible for the outpatient services provided during the encounter/visit. The only exception to this rule is that when the primary reason for the admission/encounter is chemotherapy or radiation therapy, the appropriate Z code for the service is listed first, and the diagnosis or problem for which the service is being performed listed second. Female patient received outpatient chemotherapy for breast cancer with metastasis to the axillary lymph nodes. Codes:, 2 A patient with dietary folate deficiency anemia presents for a folate injection.
