Left eye – conjunctiva + injection and chemosis stromectol 3 mg overnight delivery, slight ptosis on left generic stromectol 3 mg free shipping, pupil 5 mm reactive, + papilledema ii. Neck: full range of motion, no jugular vein distension, no stridor, Brudzinski’s and Kernig’s negative. Rectal: normal tone, brown stool, occult blood negative Case 52: Headache 227 Figure 52. This case is of a cavernous sinus thrombosis that likely developed from a sinus infection. This is a serious infection of the veins within the brain that can be life threatening if untreated. Sensory deficits in the 1st and 2nd branches (ophthalmic and maxillary branches) of the trigeminal nerve may be present. Papilledema, retinal hemorrhage, and decreased visual acuity may occur from venous congestion within the retina. Symptoms are initially unilat- eral but may become bilateral as infection and thrombosis spreads. Nonseptic or septic causes: acute infections are usually Gram positive (Staphylo- coccus aureus most common), arising from frontal, sphenoid, or ethmoid sinus infections, and dental infections; less commonly from infections of tonsils, soft palate, middle ear, or orbit. Steroids should be administered to treat thrombus and prevent possible long- term neurological defcits. Anticoagulation should be initiated with neurology consultation though evi- dence is limited. Eyes: bilateral injection, extraocular movement intact, pupils equal, reactive to light d. Neck: + cervical lymphadenopathy, full range of motion, no jugular vein disten- sion, no stridor g. The cause is unknown but affects the small and medium-sized blood vessels of the body and can lead to complications if undiagnosed and treated. Antibiotics can be started if the diagnosis is not certain; however, the patient cannot be discharged as Kawasaki disease has signifcant morbidity if not treated appropriately. The candidate should keep the patient’s mother up-to-date with his condition throughout the course of the encounter. Lips and oral mucosal fndings (dry, red, fssured lips, strawberry tongue, oropharyngeal edema) 3. Extremity fndings (erythema of palms and soles, edema of hands and feet, periungual desquamation) 4. Twenty percent of untreated patients develop coronary aneurysms between 2 to 6 weeks after disease onset. Dysrhythmias and myocardial infarction can cause sudden death in 1% to 2% of patients, usually in the 3rd or 4th week. However, 7 days ago the pain returned much more severely and was associated with right posterior leg pain, numbness and tin- gling to the thigh, leg, and feet, and slight weakness of the right leg. Yesterday he developed some problems urinating, stating that he has diffculty voiding and has on occasion wet himself. Abdomen: normal bowel sounds, soft, mild suprapubic tenderness and fullness, no rebound, guarding, or rigidity l. Neuro: normal mental status, normal cranial nerves; refexes +2 patellar bilat- eral; +1 ankle jerk on right; +2 on left; right lateral leg/foot sensory defcit; mildly decreased perianal and perineal sensation; strength 4/5 right big toe, ankle plantar fexion; 4/5 quadriceps; 4/5 left-sided lower extremities; + straight leg raise on right; unable to rise from bed because of back pain q. Cauda equina is a condition when a mass, most often the lumbar disc, pro- trudes to compress the spinal nerve roots. When asked for the neurological examination, examiner should inquire what part of the examina- tion specifcally the candidate is interested in (mental status, sensory, refexes, motor, cranial nerve, cerebellar) as well as which part of the body he/she is interested in. Cauda equina arises from massive midline disk herniation; it is a surgical emergency. Positive straight leg raise, decreased deep tendon refexes, saddle anesthesia and bowel/ bladder retention/overfow incontinence also very common. Assess for sphincter tone (60%-80% of cases have decreased tone), diminished perineal sensation (75% sensitivity for cauda equina), and postvoid residual. Within the clinical picture of cauda equina, urinary retention is 90% sensitive and 95% specifc for the diagnosis. Dexamethasone dosing is controversial but should be given to relieve edema caused by acute radiculopathy. Chest compressions (thumb-encircling hands) 100/min Case 55: Cardiac Arrest 239 b. Obtain health-care worker (such as a social worker), to talk to mother, locate other children H. Pediatric acute life support should be initiated until futility – signifcant time of resuscitation, loss of brainstem refexes, normothermia. For all cases of unexpected death in a child, abuse should be considered and excluded.

Therapeutic Considerations Although antibiotic therapy is the dominant treatment of acute and chronic bacterial sinusitis 3mg stromectol otc, it is of limited value order stromectol 3mg with mastercard. In a Cochrane review it was shown that although 80% of participants treated without antibiotics improve within two weeks, antibiotics have a small effect in patients with uncomplicated acute sinusitis who have symptoms for more than seven days. Studies indicate that among most patients with chronic sinusitis, perhaps as many as 84%, have allergies. Some particularly sensitive patients may need to have all pets removed, along with carpeting and featherbedding. Guaifenesin (also known as glycerol guiacolate) is a derivative of a compound originally isolated from beech wood that has expectorant and mucolytic properties and is available in many over-the-counter preparations. The goal with a mucolytic is to reduce the thickness and stickiness of the mucus to help promote effective clearance. Proteolytic (protein-digesting) enzymes may break down complex proteins at the site of inflammation, exert some antimicrobial effects, or act directly on mucus proteins. Trypsin, chymotrypsin, Serratia peptidase, and bromelain are the proteolytic enzymes that can break down mucus proteins and other proteins when they are administered topically. Of these enzymes, Serratia peptidase may be the most effective, while bromelain is probably the most popular and readily available. Serratia peptidase is an enzyme derived from bacteria that reside in the intestines of silkworms. It is also called “silkworm enzyme,” as it is the enzyme used to break down the cocoon of the silkworm. It is more powerful and has broader pH stability than the pancreatic enzymes chymotrypsin and trypsin. It has been used in Europe and Japan for over 25 years as a mucolytic and natural anti-inflammatory. When Serratia peptidase was given at a dose of 30 mg per day for four weeks to patients with chronic sinusitis, it significantly reduced the thickness of nasal mucus. The most popular herbal medicines historically used in the United States for sinusitis are goldenseal (Hydrastis canadensis) and echinacea (Echinacea species); see the information on echinacea in the chapter “Common Cold,” as it may be more useful than goldenseal in viral infections. The discussion below includes goldenseal and other berberine- containing plants as well as South African geranium (Pelargonium sidoides). Extracts from the rhizomes and tubers of South African geranium have been shown to exert a number of effects beneficial in upper respiratory tract infections, particularly acute bronchitis, for which it is an approved drug in Germany (see the chapter “Bronchitis and Pneumonia”). Goldenseal and Other Berberine-Containing Plants Goldenseal (Hydrastis canadensis), barberry (Berberis vulgaris), Oregon grape (Berberis aquifolium), and coptis or goldthread (Coptis chinensis) are valued for their high content of alkaloids, of which berberine has been the most widely studied. Berberine has demonstrated significant antibiotic and immune-enhancing effects in both experimental and clinical settings. Berberine has also been shown to inhibit the adherence of bacteria to human cells, so they cannot infect the cells. The primary immune-enhancing action of berberine is the activation of white blood cells known as macrophages. These cells are responsible for engulfing and destroying bacteria, viruses, tumor cells, and other particulate matter. Historically, berberine-containing plants have also been used to bring down fevers. In animal studies, berberine has produced a fever-lowering effect three times as potent as that of aspirin. However, while aspirin suppresses fever through its action on hormone-like compounds known as prostaglandins, berberine appears to lower fever by enhancing the immune system’s ability to handle fever-producing compounds produced by bacteria and other microorganisms. South African Geranium South African geranium (Pelargonium sidoides) has demonstrated immune-enhancing effects as well as antibacterial and antiviral effects and the ability to prevent adhesion of bacteria to epithelial cells. A neti pot is a ceramic pot that looks like a cross between a small teapot and Aladdin’s magic lamp. The neti pot originally comes from the ayurvedic/yoga medical tradition but has been used worldwide for centuries. Typically, to use the neti pot or another nasal irrigation device you would mix about 16 fl oz lukewarm water with 1 tsp salt. Once you’ve filled the neti pot, tilt your head over the sink at about a 45-degree angle. Put the spout into your top nostril and gently pour the saline solution into that nostril. Blow your nose to get rid of any remaining liquid, then refill the neti pot and repeat the process on the other side. A more convenient way of doing nasal rinsing is with a plastic squeeze bottle filled with the lukewarm saline solution. Various measures can be used: local application of saline through the use of a neti pot, botanicals with antibacterial and immune-enhancing properties, and basic immune system support (see the chapter “Immune System Support”). Because chronic bacterial sinusitis is often secondary to allergy, long-term control depends on isolation and elimination of the food or airborne allergens and correction of the underlying problem that allowed the allergy to develop. During the acute phase, elimination of common food allergens (milk, wheat, eggs, citrus, corn, and peanuts) is indicated until a more definitive diagnosis can be made.
