Most importantly, treatment cannot be taken during pregnancy or when breastfeeding. Chapter 18: Women and Hepatitis C Ribavirin is teratogenic (causes birth defects in the fetus) and its use in women and in their partners trying to conceive and in those pregnant is absolutely contraindicated. The effects of ribavirin are prolonged and it is necessary to wait six months after the last dose of ribavirin before trying to conceive. However, if a woman does drink, her intake should be a maximum of 1 drink per day. Fatty Liver (Steatosis) y Excess weight can lead to fat in the liver, which increases inflammation and liver damage.

Most important, thorough hand washing before and after handling foods (preparation), before eating, and after working with soil and cleaning litter boxes can help in preventing toxoplasmosis. Desiccation (drying) can also be a factor; oocyst infectivity persists longer in a moist environment than in a dry region. Exposure to temperatures at or below -13oC, for at least 24 h, will usually kill cysts. It appears that microwave heating of any of the above meats is not reliable for killing all of the T. The disease is usually self-limiting, but can be fatal to a fetus via a mother who ingested the parasite, usually after becoming pregnant, leading to miscarriage or stillbirth. Onset: Five to 23 days after ingestion from contaminated food, water, and fingers. Illness / complications: Women who become infected during pregnancy typically are asymptomatic, although the parasite (tachyzoites) can cross the placenta. In infected pregnant women, the fate of the fetus falls into three possibilities: miscarriage or stillbirth; head deformities; or brain or eye damage. However, latent infections in these individuals may cause loss of vision, when they are adults (ocular toxoplasmosis); seizures; or mental disabilities. In addition, immunocompromised individuals may develop pneumonitis, retinochoroiditis, brain lesions, and central nervous system diseases. Sulfa compounds, specifically sulphadiazine and pyrimethamine, are the chemotherapeutics of choice for treating toxoplasmosis. These drugs are usually well tolerated by infected individuals and are most effective when administered during the acute stage of infection (active multiplication of the parasite). Although treatment with sulfonamides will limit tissue cyst growth, they appear to have little effect on subclinical infections and usually will not eradicate infection. Symptoms In acute toxoplasmosis, sore lymph nodes and muscle pains develop in 10-20 % of patients and can last for several weeks, after which symptoms no longer are exhibited. Symptoms of ocular toxoplasmosis are blurred or reduced vision, tearing of, or redness in, the eye; pain; and sensitivity to light. In some cases, flu-like symptoms may appear, such as swollen lymph glands, fever, headache, and muscle aches. Individuals who progress to chronic infections may develop cysts in various muscle tissues, including brain, heart, and skeletal tissues. If illness does occur, mild flu-like symptoms (acute phase) usually last for several weeks, but can fade in a few days to months, then disappear. Reactivation of bradyzoites can occur under certain circumstances, such as when an infected person becomes immunosuppressed by other diseases or medication; under these conditions, toxoplasmosis (chronic) can develop. Route of entry: the primary routes of entry are (1) consumption of undercooked or raw, parasite-encysted (with bradyzoites) meats. Pathway: Toxoplasma gondii has a very complex life cycle, in which cats (or Felids) are the primary or "definitive" host; the animal in which parasitic sexual reproduction occurs to produce infective parasitic life forms. Large numbers of immature oocysts shed by infected cats require several days in the environment to sporulate and become infective. Oocysts are very resistant to most environmental conditions and can survive for more than a year outside of the definitive host. In the cat, the mature oocyst is degraded to release infectious organisms into the intestine. Some will invade and replicate within intestinal epithelial cells; others will penetrate through the intestinal wall and replicate throughout the body. Tachyzoites that develop within the intestinal epithelium will differentiate into sexual forms, fertilize, and develop into immature oocyts that are then shed into the environment. Infected cats will begin shedding within 3 to 10 days, and this will last for 10 to 14 days. Tachyzoites that eventually localize in tissue other than the intestinal epithelium will transform (because of an immune response by the cat) into bradyzoites contained within tissue cysts.

At a curricular or instructional level, texts-within and across grade levels-need to be selected around topics or themes that systematically develop the knowledge base of students. Within a grade level, there should be an adequate number of titles on a single topic that would allow children to study that topic for a sustained period. The knowledge children have learned about particular topics in early grade levels should then be expanded and developed in subsequent grade levels to ensure an increasingly deeper understanding of these topics. Children in the upper elementary grades will generally be expected to read these texts independently and reflect on them in writing. Preparation for reading complex informational texts should begin at the very earliest elementary school grades. What follows is one example that uses domainspecific nonfiction titles across grade levels to illustrate how curriculum designers and classroom teachers can infuse the English language arts block with rich, age-appropriate content knowledge and vocabulary in history/social studies, science, and the arts. Exemplar Texts on a Topic Across Grades the Human Body Students can begin learning about the human body starting in kindergarten and then review and extend their learning during each subsequent grade. Note on range and content of student reading Reading is critical to building knowledge in history/social studies as well as in science and technical subjects. College and career ready reading in these fields requires an appreciation of the norms and conventions of each discipline, such as the kinds of evidence used in history and science; an understanding of domain-specific words and phrases; an attention to precise details; and the capacity to evaluate intricate arguments, synthesize complex information, and follow detailed descriptions of events and concepts. In history/social studies, for example, students need to be able to analyze, evaluate, and differentiate primary and secondary sources. When reading scientific and technical texts, students need to be able to gain knowledge from challenging texts that often make extensive use of elaborate diagrams and data to convey information and illustrate concepts. Students must be able to read complex informational texts in these fields with independence and confidence because the vast majority of reading in college and workforce training programs will be sophisticated nonfiction. It is important to note that these Reading standards are meant to complement the specific content demands of the disciplines, not replace them. Read closely to determine what the text says explicitly and to make logical inferences from it; cite specific textual evidence when writing or speaking to support conclusions drawn from the text. Determine central ideas or themes of a text and analyze their development; summarize the key supporting details and ideas. Analyze how and why individuals, events, or ideas develop and interact over the course of a text. Integrate and evaluate content presented in diverse formats and media, including visually and quantitatively, as well as in words. Read and comprehend complex literary and informational texts independently and proficiently. Cite specific textual evidence to support analysis of primary and secondary sources.
The second goal when when approaching a patient with cutaneous leukocytoclastic vasculitis is to try to establish the etiology. Simple tests to be carried out immediately that help exclude severe organ disease in patients presenting with cutaneous vasculitis Urinalysis, white blood cell, red cell and platelet counts, creatinine, albumin and chest x-ray are immediate mandatory tests. Role of skin biopsy in the diagnosis of leukocytoclastic vasculitis Biopsy a fresh lesion (< 48 h old). Two deep skin biopsies should be performed, one for histology and one for direct immunofluorescence staining. Stepwise treatment approach should include: leg elevation, compression stockings, colchicine, dapsone, pentoxifylline and low-dose steroids. Additional immunosuppressive therapy is indicated in persistent cases along with a continued search for a cause/associated disease. The clinician should try to eliminate cause if known as well as treat, usually with a combination of steroids and another immunosuppressive agent. Always exclude internal organ involvement/systemic disease in patients with cutaneous vasculitis. The future also holds promise for new biologic therapies targeted more precisely to the pathogenetic mechanism responsible for vasculitis.

Only cases of severe grades of dry eye and those with associated systematic disease, needs expert opinion as well as evaluation by other fraternities like Rheumatology. The preferred practice patterns on dry eye disease is first of its kind to give a global perspective pertinent to Indian Scenario in terms of management of dry eye disease. I would like to thank Dr Samar Kumar Basak for his efforts and Dr Virender S Sangwan & Namrata Sharma, for their expert comments on the subject. Dr Ajit Babu Majji Chairman, Academic & Research Committee All India Ophthalmological Society Medical Director, Centre For Sight Ashoka Capitol Building, Road# 2, Banjara Hills Hyderabad 500034, India E mail: ajitbabu2012@gmail. Due to a wide variety of presenting symptoms, it is often unrecognized and this causes great frustration of the patient and treating physician. While these symptoms often improve with appropriate treatment, usually in majority of the cases the disease may not be curable. In many cases, dry eye disease can be a cause of significant visual morbidity and may compromise the results of cataract, corneal and refractive surgery. There are great advances in the understanding of dry eye disease over the past 10-15 years in the area of epidemiology, pathogenesis, clinical manifestation, and possibly in the therapeutic regimen. These are on the articles published in the peer-review journals on different aspect on dry eye diseases, such as, epidemiology, inflammatory aspect, tears substitutes, surgical options, newer treatment options, etc. We strive to communicate effectively with our dry eye patients, listening carefully to their needs and concerns. This is important to ensure about their active participation in decisions affecting their management, to improve their motivation and compliance with the agreed therapeutic plan, and also to help alleviate their fears and concerns about the disease. Continuous 48 counselling in every visit is an important key factor to boost up the psychological status of the patients.

In 1995: National Eye Institute/industry workshop: Consensus developed on definition, diagnosis and treatment. It is accompanied by increased osmolality of tear film and inflammation of the ocular surface. However, there are only three published reports on prevalence of dry eye among hospital-based population from North and Eastern India and the prevalence varies between 18. Target audience: Primary eye care physician/optometrists, resident/ fellow ophthalmologists, comprehensive ophthalmologists, ophthalmic private practitioners and all sub speciality ophthalmologists. Demography Epidemiology There is no doubt that in recent years, dry eye disease is an extremely common condition that causes varying degrees of ocular discomfort and disability. Thus, there has been a shift towards symptom-based assessment as the key component of clinical diagnosis. There are only three studies from India available in the peer-review journals and two of them from the North and one from Eastern India. With different diagnostic criteria the prevalence of dry eye in these studies was Between 18. Environmental factors, such as reduced humidity and increased wind, drafts, air conditioning, or heating may exacerbate the ocular discomfort. Exogenous irritants and allergens, although not believed to be causative of dry eye, may exacerbate the symptoms. Aqueous tear deficiency dry eye may develop in conditions that result in infiltration of the lacrimal gland and replacement of the secretory acini such as lymphoma, sarcoidosis,38,39 hemochromatosis, and amyloidosis. At least one symptom with moderate to severe intensity Severe symptoms of both dryness and irritation either constantly or often One or more present - often or all the time Meibomian gland dysfunction Canada America 65-84 2420 All ages 13517 Age (Year) Sample size Prevalence rate (%) 28. Atopy and chronic allergic conjunctivitis may produce dry eye due to blepharitis, conjunctival scarring, or long-term antihistamine use. Local conditions associated with dry eye: such as eyelid malposition, lagophthalmos, and blepharitis as well as neuromuscular disorders that affect blinking. Decreased tear secretion and clearance initiates an inflammatory response on the ocular surface that involves both soluble and cellular proinflammatory mediators (cytokines). In some individuals, exacerbating factors such as systemic medications or environmental conditions may lead to an acute increase in the severity of symptoms.

Immunologic Staging the second primary component of staging is immunologic staging. Other issues- infant feeding, avoiding future infection/reinfection, and disclosure-are also key components of these counseling sessions. Accuracy of Reported Lab Findings Lab results must be performed correctly, and clinical and laboratory personnel must invest time to understand the lab tests on site and minimize human error. A welldesigned referral system for lab samples will minimize confusion and allow rapid turnaround. Once a result is available, it must be carefully communicated to both patient and provider. Access An understanding of what tests are required to diagnose patients does not ensure that patients can get tested and enroll into care. For diagnostic protocols to function, patients need to be able to find their way to informed providers, and those providers need to have access to the materials needed for appropriate laboratory testing. Advocacy: Opt-Out and Provider-Initiated Diagnostic Testing In addition to maximizing access to care, providers should promote access to testing by instituting an opt-out policy. Another anticipatory strategy to maximize access to diagnostic testing is called provider-initiated testing, meaning that it Monitoring Diagnostic testing is important to both individual patients and the population as a whole. This staging system is used in many countries to determine eligibility for antiretroviral therapy. Fungal paronychia (painful, red and swollen nail bed) or onycholysis (painless separation of the nail from the nail bed). Asymptomatic bilateral swelling that may spontaneously resolve and recur, in absence of other known cause, usually painless. How to Diagnose Microscopy or culture Clinical diagnosis Clinical diagnosis Lymph node tuberculosis Non-acute, painless "cold" enlargement of peripheral lymph nodes, localized to one region. Isolation of bacteria from appropriate clinical specimens (induced sputum, bronchoalveolar lavage and lung aspirate) Severe recurrent bacterial pneumonia Symptomatic lymphocytic No presumptive interstitial pneumonia clinical diagnosis Cxr: bilateral reticulonodular interstitial pulmonary infiltrates present for more than 2 months with no response to antibiotic treatment and no other pathogen found. Not required but may be confirmed by: 1) typical red-purple lesions seen on bronchoscopy/ endoscopy; 2) dense masses in lymph nodes, viscera, or lungs by palpation or radiology; and 3) histology. Computed tomography scan (or other neuroimaging) showing single or multiple lesions with mass effect or enhancing with contrast.

Oral fluid human immunodeficiency virus tests: improved access to diagnosis for infants in poorly resourced prevention of mother to child transmission programs. Also, the virus can develop resistance to these medications, in much the same way that bacteria can become resistant to the effects of antibiotics. Patient motivation is important to ensure that medication schedules are followed precisely. With these caveats in mind, most clinicians who treat adults follow standard criteria for starting medications. After 12 months of age, the risk of rapid disease progression begins to slow, and expert opinion is that deferring treatment can be considered for older children. However, there were two deaths in the study attributed to nevirapine use, one from fulminant 52 U. But for more minor skin rash-which is common in the early weeks of treatment, particularly with nevirapine- or for hepatotoxicity, the question arises in clinical practice whether it is safe to switch between efavirenz and nevirapine. Oncedaily administration of lopinavir/ritonavir, unboosted azatanavir, and both fosamprenavir and ritonavir-boosted fosamprenavir are listed by the U. Guidelines recommend that emtricitabine may generally be used in place of lamivudine or vice versa). If a child or adult fails the first-line regimen, he or she is switched, per the criteria and expert judgment outlined earlier, to the second-line regimen. Unboosted atazanavir regimens are not recommended for children younger than 13 years and weighing less than 39 kg. However, a study conducted in Zambia and Malawi found that children taking half or one-quarter of a Triomune pill were often underdosed on nevirapine and were more stunted than those receiving optimal dosing.

Additional conditions were identified that may affect A1C test accuracy including the postpartum period. Prevention or Delay of Type 2 Diabetes this section was moved (previously it was Section 5) and is now located before the Lifestyle Management section to better reflect the progression of type 2 diabetes. The nutrition section was updated to highlight the importance of weight loss for those at high risk for developing type 2 diabetes who have overweight or obesity. Because smoking may increase the risk of type 2 diabetes, a section on tobacco use and cessation was added. Comprehensive Medical Evaluation and Assessment of Comorbidities professional audiences in an informative, empowering, and educational style. A new recommendation was added to explicitly call out the importance of the diabetes care team and to list the professionals that make up the team. The table listing the components of a comprehensive medical evaluation was revised, and the section on assessment and planning was used to create a new table (Table 4. A new table was added listing factors that increase risk of treatment-associated hypoglycemia (Table 4. The fatty liver disease section was revised to include updated text and a new recommendation regarding when to test for liver disease. Therefore, more discussion was added about the importance of macronutrient distribution based on an individualized assessment of current eating patterns, preferences, and metabolic goals. There is not a one-size-fits-all eating pattern for individuals with diabetes, and meal planning should be individualized. A recommendation was modified to encourage people with diabetes to decrease consumption of both sugar sweetened and nonnutritive-sweetened beverages and use other alternatives, with an emphasis on water intake. The sodium consumption recommendation was modified to eliminate the further restriction that was potentially indicated for those with both diabetes and hypertension. Additional discussion was added to the physical activity section to include the benefit of a variety of leisure-time physical activities and flexibility and balance exercises. The discussion about e-cigarettes was expanded to include more on public perception and how their use to aide smoking cessation was not more effective than "usual care. Glycemic Targets intermittently scanned ["flash"]), and automated insulin delivery devices. The recommendation to use selfmonitoring of blood glucose in people who are not using insulin was changed to acknowledge that routine glucose monitoring is of limited additional clinical benefit in this population. Obesity Management for the Treatment of Type 2 Diabetes abbreviated, as these are not generally recommended. Cardiovascular Disease and Risk Management A recommendation was modified to acknowledge the benefits of tracking weight, activity, etc. A brief section was added on medical devices for weight loss, which are not currently recommended due to limited data in people with diabetes. The recommendations for metabolic surgery were modified to align with recent guidelines, citing the importance of considering comorbidities beyond diabetes when contemplating the appropriateness of metabolic surgery for a given patient. Pharmacologic Approaches to Glycemic Treatment this section now begins with a discussion of A1C tests to highlight the centrality of A1C testing in glycemic management. The self-monitoring of blood glucose and continuous glucose monitoring text and recommendations were moved to the new Diabetes Technology section. To emphasize that the risks and benefits of glycemic targets can change as diabetes progresses and patients age, a recommendation was added to reevaluate glycemic targets over time. The section was modified to align with the living Standards updates made in April 2018 regarding the consensus definition of hypoglycemia. A recommendation that, for most patients who need the greater efficacy of an injectable medication, a glucagon-like peptide 1 receptor agonist should be the first choice, ahead of insulin. A new section was added on insulin injection technique, emphasizing the importance of technique for appropriate insulin dosing and the avoidance of complications (lipodystrophy, etc. The section on noninsulin pharmacologic treatments for type 1 diabetes was For the first time, this section is endorsed by the American College of Cardiology. Additional text was added to acknowledge heart failure as an important type of cardiovascular disease in people with diabetes for consideration when determining optimal diabetes care. The blood pressure recommendations were modified to emphasize the importance of individualization of targets based on cardiovascular risk.

And since 15 percent of cystic thyroid nodules are malignant, ultrasound determination that a nodule is cystic does not rule out thyroid cancer (Table 6). There is typically a delay of 20 years or more between radiation exposure and the development of thyroid cancer. The risks are substantially greater for those patients living nearby the test sites for many years. Fortunately these cancers will likely be of the well differentiated type which have an excellent prognosis; the vast majority of these can be cured. There is no evidence that children are at increased risk of developing thyroid cancer, the small increase risk appears to be limited to those that were directly exposed in the past. Despite these increased risks, thyroid cancer is still relatively uncommon and usually curable. Symptoms and Diagnosis of Thyroid Nodules Most thyroid nodules cause no symptoms at all. Nodules are usually found by patients who feel a lump in their throat or see it in the mirror. Occasionally, a family member, friend or physician will notice a strange lump in the neck of someone with a thyroid nodule. Occasionally, nodules may cause pain, and even rarer still are those patients who complain of difficulty swallowing when a nodule is large enough and positioned in such a way that it impedes the normal passage of food through the esophagus (which lies behind the trachea and thyroid). After an appropriate work-up, if any of the above questions are answered "yes", then medical or surgical treatment is required. However, most thyroid nodules will yield an answer of "no" to all of the above questions. In this most common situation, there is a small to moderate sized nodule that is simply an overgrowth of "normal" thyroid tissue, or even a sign that there is too little hormone being produced. Patients with a diffusely enlarged thyroid (called a goiter) will present with what is perceived at first to be a nodule, but later found to be only one of many benign enlarged growths within the thyroid. A nodule which is over-producing thyroid hormone will show up darker and is called "hot". Also, that 85% of cold nodules are benign, 90% of warm nodules are benign, and 95% of hot nodules are benign. Although thyroid scanning can give a probability that a nodule is benign or malignant, it cannot truly differentiate benign or malignant nodules and usually should not be used as the only basis for recommending treatment of the nodule, including thyroid surgery. The ultrasound test is quick, accurate, cheap, painless, and completely safe, and thus is routinely performed. This test usually takes only about 10 minutes and the results can be known almost immediately. The sound waves are emitted from a small hand-held transducer that is passed over the thyroid. This test will usually determine if a nodule has a low chance of being cancer (has characteristics of a benign nodule), or that it has some characteristics of a cancerous nodule and therefore should be biopsied. In this test, a very small needle is passed into the nodule and some cells are aspirated. The cells are placed on a microscope slide, stained, and examined by a pathologist. A nondiagnostic aspirate should be repeated, as a diagnostic aspirate will be obtained approximately 50% of the time when the aspirate is repeated. Overall, five to 10% of biopsies are nondiagnostic, and the patient should then undergo either an ultrasound or a thyroid scan for further evaluation. Benign thyroid aspirations are the most common and consist of benign follicular epithelium with a variable amount of thyroid hormone protein (colloid). Malignant thyroid aspirations can diagnose the following thyroid cancer types: papillary, follicular variant of papillary, medullary, anaplastic, thyroid lymphoma, and metastases to the thyroid. Since benign follicular adenomas cannot be differentiated from follicular cancer (~12% of all thyroid cancers) these patients often end up needing a formal surgical biopsy, which usually entails removal of the thyroid lobe which harbors the nodule. Twenty five percent of suspicious lesions are found to be malignant when these patients undergo thyroid surgery.

Most patients will continue to demonstrate slow healing at the site of the median sternotomy. An active bone scan may be found up to 4 years after surgery due to compromise of the sternal blood supply as a result of harvesting the internal mammary artery. Usual Course Without treatment the pain may decrease in intensity during the first year post surgery, may remain the same, or may become intractable. Thoracic sympathetic ganglia blocks may significantly reduce pain, allodynia, and bone tenderness but only temporarily. Complications Pain can be compounded by emotional stress and suspicion of recurrence of heart disease. Social and Physical Disability Depending on the degree of discomfort, impairment ranges from negligible to serious. Diagnostic Criteria Burning pain, numbness, hyperesthesia and deep bone tenderness are almost all simultaneously present at the area of harvesting of the graft. Patients may benefit from reassurance that this pain does not arise from recurrent heart disease. Differential Diagnosis Ischemic heart pain, costochondritis, hyperesthesia from the scar. Site Anterior thorax, usually left side and occasionally bilaterally (always at the site of the graft). Main Features Burning pain across a well-circumscribed area defined by the sternum medially, the intercostal junction at T2 or T3 superiorly, the intercostal junction at T5 or T6 inferiorly, and approximately the nipple line laterally. Site Either symmetrical, more often in the posterior thoracic region, or precordial. Main Features Tension pain is rare in the posterior thoracic region compared with tension headache (perhaps one-tenth or less of the frequency of the latter). Precordial pain is more common, often associated with tachycardia or a fear of heart disease. The other features of these pains are the same as for muscle tension pain in general (I11-1, 2). Most frequent in precordium; may be associated with tachycardia and fear or conviction of heart disease being present. Main Features Deep, dull and often poorly localized pain in epigastrium with tenderness beneath the rib margin. Usual Course Treatment with antibiotics with or without surgery usually leads to resolution. Social and Physical Disability May lead to usual effects both of chronic sepsis and chronic pain. Summary of Essential Features and Diagnostic Criteria Chronic illness often after abdominal surgery with fever and abdominal pain, often with shoulder tip radiation. Site Pain can be related either to the organ herniating or the walls of the orifice. Main Features Burning epigastric pain (or retrosternal pain, or both), often following eating or lying recumbent. Associated Symptoms the patient may also complain of chest pain similar to angina, right upper quadrant abdominal pain similar to that in cholelithiasis, epigastric pain like that in peptic ulcer disease, abdominal bloating and air swallowing. Radiographic techniques will show evidence of abdominal viscera in places they are not supposed to be, such as gastric mucosa above the diaphragm or colon above the diaphragm. Usual Course Pain typically is intermittent and aggravated by certain foods, aspirin, alcohol, bending over or straining, abdominal pressure or tight clothing, and carbonated beverages. Likewise, more esophageal reflux may occur with caffeine or nicotine, which relax the lower esophageal sphincter. Page 147 Social and Physical Disability May lead to chronic complaint, usually not too severe. Etiology Traumatic and congenital or degenerative weaknesses in the diaphragm are of key etiologic significance, although the exact cause is often obscure. Summary of Essential Features and Diagnostic Criteria Epigastric discomfort and esophageal reflux are key symptoms, with radiographic or endoscopic evidence of extra-abdominal organs. Differential Diagnosis Angina, cholelithiasis, acid-pepsin disease without hernias, and pancreatitis, etc. Relieving factors include smooth muscle dilatation agents such as glyceryl trinitrate or amyl nitrite, which may relieve the pain. Signs and Laboratory Findings Patients usually point out their pain with one finger.

The patient complains of sore eyelids and ocular discomfort with little discharge. Bacterial culture is usually needed to identify the organism responsible for patients with chronic bacterial conjunctivitis. Tearing results from lashes abrading the globe Irritation, burning, and foreign body sensation. It presents very similarly to acute bacterial conjunctivitis, though it may be seen as smoldering chronic conjunctivitis in some cases. The common symptoms include ocular irritation, scant mucopurulent discharge, glued eyelids upon awakening and blurred vision. Patients do not respond well or fully to typical antibiotics that are prescribed for acute bacterial conjunctivitis. Treatment includes erythromycin ophthalmic ointment and oral therapy with azithromycin (single one gram dose) or doxycycline (100 mg twice a day for 14 days) to clear the infection. Seasonal allergic conjunctivitis is often the most common type and it is related to specific environmental allergens. Symptoms include bilateral eye lacrimation, itching, and diffuse erythema (Figure 1). Large cobblestone papillae under the eyelid and chemosis may be present in severe cases. Over-the-counter oral antihistamines and topical histamine H1-Receptor antagonists can help alleviate symptoms. It presents with chronic itching, photophobia, blurred vision, discoloration of the periorbital area and a thick, clear, stringy discharge. Everting the eyelids may reveal large flat papillae in severe cases of giant papillary allergic conjunctivitis. If the cornea appears hazy, ulcerated or symptoms fail to improve, the patient should be referred to an ophthalmologist for treatment. Treatment initially includes frequent use of artificial tears throughout the day and nightly application of lubricant ointments. In general, if treatment beyond lubricants proves ineffective, the dry eye, the patient should be referred to an ophthalmologist. If blepharitis is suspected, the patient should be evaluated for seborrheic dermatitis that is associated with scalp or facial flaking, as well as rosacea, which is associated with redness and swelling on the nose or cheeks. Treatment is supportive care such as eyelid hygiene, lid massage and warm compresses. When a patient does not respond to supportive care, topical erythromycin or bacitracin ophthalmic ointment can be used. In severe cases, oral antibiotics such as doxycycline or tetracycline may be considered. Treatment consists of antibiotic eye drops and/or ointment to prevent infection, supportive care, cycloplegics and pain control. If symptoms do not improve within 48 hours, the patient should be referred to an ophthalmologist. Ophthalmologist referral is warranted if there is corneal involvement, history of blunt trauma, drainage, or persistent pain. Treatment consists of supportive care and artificial tears, but in some cases may require a short course of topical steroids. Congenital ptosis results from a malformed levator muscle, while acquired ptosis may be due to the gradual thinning or disinsertion of the levator aponeurosis. For congenital or acquired ptosis, surgery is performed to tighten the levator aponeurosis or resect the levator muscle. The third (oculomotor) cranial nerve innervates all the extraocular muscles except the lateral rectus and superior oblique. Etiologies of the third nerve palsy include ischemic cranial mononeuropathy, vasculitis, compression of the third nerve by an aneurysm, tumor, or uncal herniation and trauma. Magnetic resonance imaging of the brain with contrast is required when there is no obvious vascular risk factor. If symptoms are seen in young patients, or there is suspicion for an aneurysm, cerebral angiography may be necessary.
