This week's very cool case was donated by Dr. Mike Feely. We haven't had anything like this one before on the blog!The specimen below was submitted by a young woman who found this " worm " by her arm, right below her mouth, upon waking from a nap. She reported having abdominal pain with associated diarrhea for several weeks prior to presentation, but was otherwise healthy. After being in formalin:Histologic sections (H&E):Identification? Any additional information that you would like?

In this study, we report the first case of gastric anisakiasis in Poland, in a 59-year-old female patient, after eating raw Atlantic salmon (Salmo salar). The parasite was identified as the third-stage larva of Anisakis simplex sensu stricto on the basis of morphology and molecular analysis. The larva was still alive and causing pain until it was removed, which occurred more than 5 weeks after infection. The described case prove that anisakiasis should be considered as a potential cause of gastrointestinal tract ailments following the consumption of seafood in countries where no cases of this zoonosis have been reported to date.

Vernick, Brice Rotureau, Christian Mitri During a blood meal, femaleAnopheles mosquitoes are potentially exposed to diverse microbes in addition to the malaria parasite,Plasmodium. Human and animal African trypanosomiases are frequently co-endemic with malaria in Africa. It is not known whether exposure ofAnopheles to trypanosomes influences their fitness or ability to transmitPlasmodium. Using cell and molecular biolog...

A 13-year-old girl presented with recurrent abdominal pain of 3  months' duration that appeared after menarche. Physical examination revealed tenderness over the left ovarian point. Laboratory tests (hemogram, biochemistry, urinary sediment, celiac disease serology, fecal parasites, and calprotectin) and the abdominal ultrasound were normal. Computed tomography angiography (Figure, A) and magnetic resonance imaging showed a double left renal vein with a retroaortic component, prominent left parauterine circulation, and engorged ipsilateral ovarian vein (caliber of 8 mm and grade II reflux).

AbstractBlastocystis is a parasite with a worldwide distribution and a varying prevalence in different countries. The pleomorphic nature of the protozoon and the lack of understanding a possible pathogenesis have led to confusion regarding its clinical significance. The aim of the study was to shed light on clinical characteristics of pediatric patients in Swiss children with a positive stool sample forBlastocystis, in order to provide recommendations for a practical approach for the clinician to know whom, when, and how to test. This is a retrospective study of pediatric patients, whose stool has been tested positive forB...

In this study, 50 stool samples were collected from human cases of G. lamblia. referred to health centers in Sari, Babol, Nowshahr cities. The samples were examined by formalin-ether concentration procedure. DNA extraction was carried out on samples containing adequate Giardia cysts, and then PCR-RFLP was done on glutamate dehydrogenase (gdh) marker. RESULTS: In these patients, the most common signs were abdominal pain (42.9%), diarrhea (47.6%) and least marked common signs was malaise (4.7%). Of all 21 isolates, 9 samples (42.8%) were found as genotype mixed AII and BIII, 6 samples (28.6%) belonged to genotype BIII a...

In conclusion, the ovarian location of HD should be considered in any differential diagnosis of a cystic lesion, while it does not exclude synchronous ovarian tumors. These cases reinforce the necessity of better measures of prophylaxis and screening of HD in endemic areas. PMID: 31912083 [PubMed - in process]

Publication date: January 2020Source: Pathology - Research and Practice, Volume 216, Issue 1Author(s): Hui Wang, Rani KanthanAbstractAmoebiasis, caused by the intestinal protozoan Entamoeba histolytica, though a relatively common parasitic disease in the tropical and subtropical regions, is uncommon in the developed countries. In these countries, as amoebic colitis shares similar clinical symptoms and endoscopic features with inflammatory bowel disease (IBD), these cases can be easily unrecognized and misdiagnosed.In this case report, we discuss the case of an adult patient with invasive intestinal amoebiasis, who was init...

Rationale: Myiasis is a parasitic disease caused by fly larvae of the Diptera order that infest human and other vertebrate animal tissues. Orbital myiasis is a potentially destructive infestation of the orbital tissues, which may affect individuals with previous ocular diseases or disorders of consciousness. Patient concerns: A 72-year-old man presented with a complaint of repeated pain for two years after trauma to his right eyelid and aggravated symptoms with larvae wriggling out for 2 days. An orbital computed tomography scan revealed right eyeball protrusion and periocular soft tissue edema. Two days later, magnet...
