Microneedle Patch for Antibiotic-Free Acne Treatment
Researchers at the University of Hong Kong have developed a microneedle patch for the drug-free treatment of skin infections, such as acne. Acne is often treated using antibiotics, but these have limited effectiveness over the long term and can result in drug-resistant bacteria. In an effort to develop a drug-free alternative, these researchers have created a microneedle patch that is ultrasound responsive. The patch contains zinc-based nanomaterials that produce a substantial amount of reactive oxygen species when stimulated using ultrasound. These reactive oxygen species are highly effective at killing acne-causing bacte...

Case of the Week 723
This week ' s case was donated by Dr. Nancy Wengenack and the Mycology lab at Mayo Clinic. These objects were found in a fungal culture for dermatophytes (lactophenol blue stain). What are they, and what is their significance? (Source: Creepy Dreadful Wonderful Parasites)

Answer to Case 723
Answer to theParasite Case of the Week 723: mite, not scabies. Given that this mite was found in a fungal culture from skin scrapings, it could very well be a dust mite (Dermatophagoidessp.) as many of you suggested. However, mites are challenging to identify, so genus/species level identification is best left to the acarologists (people who study mites and ticks). The biggest concern here is its location - on a fungal culture in the mycology laboratory. Mites are a terror in the mycology lab. They crawl from plate to plate, contaminating and destroying cultures from patient samples. In most cases, the culture plates ...

Case of the Week 722
This week ' s (rather disturbing) case was generously donated by Dr. Niels Olson. This is a parasite found in salmon throughout the world - sorry sushi lovers - no slight is meant against any commercial provider of salmon. Parasitism is a fact of life. What is the likely identification of this parasite? What would happen if it was ingested without cooking or freezing? (Source: Creepy Dreadful Wonderful Parasites)

Answer to Case 722
Answer to theParasite Case of the Week 722: anisakid larvae, one of the members of theAnisakis simplex, Pseudoterranova decipiens,or Contracecum osculatumcomplex. Humans can become transiently infected with the larvae when they are ingested in undercooked fish, such as this salmon. The larvae may embed in the gastric or intestinal mucosa, causing intense pain. Endoscopic removal is curative. In less severe cases, the larvae will migrate back up the esophagus and out the mouth - a much preferred (but disturbing!) alternative. They can also be passed in the stool. In these settings, the larvae have to be differenti...

Case of the Week 721
Happy American Independence day (July 4th) and a belated Canada day (July 1st)! As an American, this weeks case very appropriately has a lot of red, white, and (purple-ish)blue. The following round objects were seen in a stool specimen on modified acid fast. The patient has had more than 1 week of profuse watery diarrhea and abdominal discomfort.These objects were also highlighted with using calcofluor white fluorescence staining (arrow) along with stool flora.What are these objects? Are they fungus or parasite? (Source: Creepy Dreadful Wonderful Parasites)

Answer to Case 721
Answer to theParasite Case of the Week 721:Cryptosporidiumsp. oocysts. These oocysts are a parasite, even though they stain with the non-specific calcofluor white fluorescent dye. Also, the abbreviation " crypto " is often used to refer to eitherCryptosporidium(parasite) orCryptococcus(fungus), so it ' s always good to make sure you audience know what you were talking about!Cryptosporidiumspp. oocysts are one of several intestinal parasites that stain red with the modified acid fast stain;Cyclosporaspp. andCystoisospora belli are the other two. Note that these 3 parasite genera are commonly referred to as coccid...

Answer to Case 719
Answer to theParasite of the Week 719:Cyclosporasp. oocysts. WhileCryptosporidiumspp. oocysts have a similar appearance, they are smaller thanCyclosporaoocysts, measuring only 4-6 micrometers in diameter. Note thatCyclospora oocysts do not stain uniformly with either the modified acid fast or modified safranin methods, although there tends to be fewer unstained oocysts with the latter. The microwave modification of the safranin stain will also improve the staining uniformity (see the CDC procedureHERE).As Dr. Marc Couturier pointed out on Twitter, there are now three morphologically-identical species o...

Matthew ’s health care tidbits: Hedge Funds that Do Health Care on the Side
Each time I send out the THCB Reader, our newsletter that summarizes the best of THCB (Sign up here!) I include a brief tidbits section. Then I had the brainwave to add them to the blog. They’re short and usually not too sweet! –Matthew Holt
Lots of news about bad behavior in health care this week, with real shots about patient & staff safety at home care company Papa, and Grail misinforming 400 people that they had cancer. But the prize for tone deafness this week comes from another very well funded health care provider system being heartless to its poorest patients.
This week it’s Allina, a Minn...

Answer to Case 718
Answer to theParasite Case of the Week 718: ciliated epithelial cells; NOTLophomonas. Many of our readers suspected this case to representLophomonas blattarum- a flagellated protozoan parasite of cockroaches - but there is no convincing evidence thatLophomonas is actually a human parasite. Also, there are a number of helpful features that can differentiate ciliated human epithelial cells fromL. blattarum:1. Human ciliate epithelial cells have a well-defined terminal bar with a compact row of short cilia (arrows) rather than the tuft of long flagella possessed byLophomonas. This is nicely demonstr...
