Test your medicine knowledge with the MKSAP challenge, in partnership with the American College of Physicians.
A 32-year-old man is evaluated for a 2-week history of a rash on his face and midchest. He describes the rash as consisting of small, reddish “lumps” that are intensely itchy; they develop and begin to resolve with development of new lesions. He otherwise feels well.
Medical history is significant for a recent diagnosis of HIV infection. Medications are tenofovir, emtricitabine, efavirenz, and trimethoprim-sulfamethoxazole. On physical examination, vital signs are normal. The patient has 1- to 3-mm p...

Red Dust, dingoes, trauma and Sepsis
Guest post by Dr Chris Edwards of EMJourney recounts his time as a remote retrieval registrar based in Alice Springs – @EMtraveller
I’ve had the privilege to work as a Retrieval Registrar for the Alice Springs Hospital Retrieval Service in Central Australia for the last 6 months. How to describe it – words that spring to mind include:
Challenging (unlike many other retrieval jobs, you often are intimately involved in the logistics planning)
Satisfying (providing ICU level care to the most remote parts of Australia)
Scary (providing ICU level care to the most remote parts of Australia!)
Clinical character formi...

A Week of Hard but Rewarding Work in Honduras
By Mara Levitt, MD, & Ashley Davis, MD
Honduras, a Central American country bordered by Guatemala, El Salvador, and Nicaragua, is home to more than eight million people, and produces minerals, coffee, tropical fruit and sugar cane. The capital, Tegucigalpa, is divided into 18 departments; we traveled to Intibuca.
Honduras has the highest rate of homicide in the world. The water supply and sanitation varies from modernized water treatment systems to basic systems, from sewer systems to latrines and basic septic pits. A lack of maintenance leads to poor water quality, and residents’ health varies depending on...

Answer to Case 278
Answer: Demodex sp. mitesThere are 2 described species of human Demodex mites: D. folliculorum found in hair follicles, and D. brevis, found in sebaceous glands. Demodex canis infects dogs but can also be a zoonosis in humans. These little guys can be considered normal fauna of humans and are found in up to 2/3 of elderly individuals. Fortunately most individuals are asymptomatic.Most labs usually use a simple wet-prep when looking for Demodex mites. In this case, these mites were a fortuitous find on a preparation designed to identify dermatophytic fungi and are probably not the cause of the patient's symptoms...

Answer to Case 277
Answer: Egg of the scabies mite, Sarcoptes scabei. Note that you can still see it moving within the egg. The scabies mite has short 'stumpy' legs that terminate in long spines (see case 236) and one of these spines can be seen moving inside of the egg in this case. Just for fun, we tried to allow the egg to hatch; however it eventually stopped moving and we think that the mineral oil in which the specimen was collected ended up suffocating the mite before it could emerge.

Getting Personal: What It’s Really Like Living With a Sexually Transmitted Infection (STI)
by Jenelle Marie
When you hear the term STD (sexually transmitted disease) or STI (sexually transmitted infection), what do you think of first?
Grotesque pictures of maimed genitalia displayed on a projector during yesteryear’s sex-ed class geared toward frightening you into abstinence? That scene from ” The Hangover” where Sid says, “What happens in Vegas stays in Vegas … except for herpes. That shit will come back with you”?
Whatever first comes to your mind is not likely to include your neighbor, professor, or best friend living with an STI, having an incredible sex life, and otherwise prospering. Th...

Interesting Case of " Co-rumination "
I haven ' t written much about actual medical cases I see here at my hospital but this one intrigued me. Some details have been altered of course. < br / > < br / > A 30ish female showed up in our emergency department complaining of a sharp, stabbing pain in her left neck (10 out of 10 in intensity) for several days along with a palpable mass over the area. The pain had been present for two to three months but not nearly this intense nor had the mass been as large. She also complained of fatigue, shortness of breath, tactile fevers (felt hot but hadn ' t actually checked her temperature), and a range of other symptoms....
