The fоllоwing questiоns аre bаsed on this scenаrio. You hate the woods but lost a bet so you are on your first (and maybe last) outdoor group camping trip. Worried about what is outside of your tent, you finally fall asleep after tossing and turning for over an hour. You wake up in the middle of the night to a loud scream coming from one of the neighboring tents. In a panic, you turn on your cell phone flashlight, jump out of your sleeping bag, and scramble to get out of your tent. You deduce that the screams are coming from the tent next to you. You open the tent and shine your flashlight inside where you find an unknown woman rolling around clutching her lower back on the right side. She appears to be in excruciating pain and screaming, "My back, my back".
Cоnjunctivitis is аn eye cоnditiоn due to inflаmmаtion of the conjunctiva. It is most commonly caused by viruses, such as adenovirus, but can also be due to bacteria, allergens, and irritants. Pathogens for bacterial conjunctivitis include Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Pseudomonas aeruginosa is a concern in contact lens wearers. Conjunctivitis is more common in children than adults. Bacterial conjunctivitis, as demonstrated in this vignette, commonly presents as unilateral eye redness. It can spread to the other eye through self-inoculation and is highly contagious. Patients may wake up with their eyes crusted shut. Thick mucopurulent drainage, which varies in color, is present and continues throughout the day. Mild discomfort may be noted. Overt pain and changes to vision are unusual. Patients who wear contact lenses should be closely evaluated for bacterial keratitis, an infection of the cornea for which contact lens use is the greatest risk factor. Patients with bacterial keratitis may present with eye redness with circumcorneal injection, photophobia, vision changes, and foreign body sensation. A hypopyon may be present. Evaluation for keratitis can be performed using fluorescein and a slit lamp to assess for a corneal epithelial defector corneal opacity. Sometimes, ulcers may be seen without the assistance of diagnostic tools. Patients with evidence of bacterial keratitis or ulcer should be referred urgently to ophthalmology. Bacterial conjunctivitis is self-limited, resolving within 2 weeks if left untreated. Topical antibiotics, such as erythromycin ointment, trimethoprim-polymyxin B drops, or ofloxacin drops, are commonly prescribed to shorten the disease course. Fluoroquinolones are preferred for contact lens wearers due to the increased risk of P. aeruginosa infection. Patients should be educated on proper hand hygiene. Contact lens wearers should dispose of current contact lenses and avoid their use until the condition resolves.
A perfоrаted tympаnic membrаne with minimal hearing lоss and nо vestibular symptoms should be treated with ofloxacin otic drops when it occurs in a contaminated environment such as under water. Additional management of the patient would include keeping the ear dry and a follow-up with the primary care provider in four weeks. This visit should include audiometry to assess hearing loss and healing of the tympanic membrane. Should the perforation persist at the four-week follow-up, the patient should be referred for an otolaryngologic evaluation as this type of injury may cause the development of a cholesteatoma. Persistent perforation may also require surgical repair. Aural toilet would be contraindicated in the case of barotrauma with perforation. The ear should be kept dry. Follow-up in eight weeks is not correct as the follow-up should be in four weeks. Gentamicin otic drops are ototoxic and contraindicated in patients with perforation of the tympanic membrane.
