Diagnosis
Know that acute otitis media in the first six weeks after birth requires careful evaluation and follow-up
Know that pneumatic otoscopy is the preferred generally available method of diagnosing middle ear effusion because dimished tympanic membrane mobility usually accompanies middle ear effusion
Know the clinical manifestations of acute otitis media:fever may or may not be present, otalgia, nonspecific symptoms (eg, irritability)
When I look into a child's ears to determine whether or not she has an infection of the middle ear, I'm supposed to use my instrument to blow a puff of air onto the eardrum. If it flexes normally, all is well; otherwise a lack of compliance suggests fluid there: but is it infected or not?.
The strict criteria for an ear infection as opposed to just having fluid in the middle ear includes three things 1) acute onset 2) an exam consistent with having middle ear fluid and 3) signs of inflammation there. The onset is usually pretty easy, but fluid that is not infected can accumulate rapidly as well, and uninfected fluid can hurt. Signs of inflammation are rampant, being either pain or redness: most children come in for ear pain, and one good cry is enough to make the eardrum as red as the child’s face. The exam for a middle ear effusion should be fairly easy, but with a frantic child in pain, it is often technically difficult. Wax gets in the way, the child moves, and curiously enough, our clinic doesn’t have any of the insufflation bulbs required to check ear drum compliance. When pus comes draining out of the ear (a sign of middle ear fluid), I sometimes heave a sigh of relief and get ready to write for some medicine.
I really like the AAP guideline’s little chart for diagnosing an ear infection, so I’ll reproduce it here:
A diagnosis of AOM requires 1) a history of acute onset of signs and symptoms, 2) the presence of MEE, and 3) signs and symptoms of middle-ear inflammation. Elements of the definition of AOM are all of the following:
1. Recent, usually abrupt, onset of signs and symptoms of middle-ear inflammation and MEE
2. The presence of MEE that is indicated by any of the following:
a. Bulging of the tympanic membrane
b. Limited or absent mobility of the tympanic membrane
c. Air-fluid level behind the tympanic membrane d. Otorrhea
3. Signs or symptoms of middle-ear inflammation as indicated by either
a. Distinct erythema of the tympanic membrane or
b. Distinct otalgia (discomfort clearly referable to the ear[s] that results in interference with or precludes normal activity or sleep)
Abbreviations: TM, AOM, OME, MEE

Teaching Students How To Consult Specialists
I subscribe to several medical Twitter feeds, ones that are 1) useful 2) have a readable frequency of posting 3) and are relevant.
Thanks to the feed by "Dr. Ves", I found a cute survival guide written for first-year general practitioners in the United Kingdom. Now their medical education system differs from ours significantly, as well as their whole funding, but I was excited to find this new mnemonic: SBAR.
Situation: I am [med student, resident, doc] on [the general inpatient service, the urgent care clinic, the pediatric clinic], and I need your help with [x].
Background: give patient's age, reason for presentation to your service, current status, problem, relevant history and exam, relevant labs, etc.
Assessment: I think the problem is x
Recommendation: I want to do this, what would you recommend. OR I need you to see them.
(Record: record your conversation, the plan, and if they are consulting, the time frame)
I like that it gives a nice framework for students to think about speaking to a consultant. Oftentimes we tell them "call nephrology", and they are awkward and incomplete on the phone, despite coaching. However, this acronym, SBAR, is entirely new to me, and I find it hard to remember. Another acronym and mnemonic SOAP, is a framework we teach for writing notes, and it also appears in the guide for new physicians. Notes, it appears, are universal. It will be easy and convenient to remind students of what they know and frame their call to the consultant in a SOAP format.
Subjective: how is the patient doing, what brought them in, what are their concerns
Objective: background/history, age, labs, exam
Assessment: as above
Plan: as "recommendation" above
Abbreviation: sbar, UK, soap

Vegetarianism and Other Weighty Matters
Recognize that nutritional deficiencies may develop in infants who are fed nontraditional diets (eg, goat milk, vegetarian)
Minh is currently a lacto-ovo-vegetarian. I did cheat twice with some bits of my ham sandwich and some chicken, but other than that he's not had meat. My main reason is that I think it's healthier, and I don't want to change stinky diapers. The fruity ones are bad enough. Eeew.
Anyway, Minh's weight percentile has dropped since I started working again when he was six months, and while he doesn't look like a refugee, just slender, I worry because I'm his mom. According to a recent Peds in Review article co-authored by a medical school classmate of mine, Minh is probably getting adequate B12 from his diet, since he consumes eggs every morning. He is also likely getting adequate protein, as most vegetarians consume more than the minimum amount of protein. He was tested at 6 months for anemia, and his hemoglobin level was fine, so I'm not as worried about that. A lot of vegetarians eat high-fiber, low calorie diets, though, and that may be Minh's problem.
Now, if he were vegan, I would at this time be worried about his B12 levels, as well as calcium, folate, iron, and zinc. Right now, though I think that I just have to introduce him to more fatty foods, and foods that have omega 3 fatty acids. I'm thinking greek yogurt and tofu right now. I've got the Moosewood Collective cookbooks I like out in front of me, and I'm planning on vegetarian mayhem tonight.
