The exception is Trichinella pseudospiralis whose larvae are not encapsulated compared to T. spiralis, T. nativa, T. nelsoni, T. britovi, and T. murrelli which do have encapsulated larvae. These species are the predominant to infect humans. Answer, Part II: What is the most common source of infection worldwide? Domestic pigs. What about in the United States?

Note the small (2-5 micron) oval-shaped objects within and outside of macrophages, with a nucleus and classic rod-shaped kinetoplast. The large purple objects are macrophage nuclei. Splenic aspiration is an excellent way of diagnosing visceral leishmaniasis. However, the procedure carries the risk of splenic rupture and should only be undertaken by a skilled practitioner. An alternative procedure for diagnosis of visceral leishmaniasis is bone marrow biopsy. Visceral leishmaniasis is prevalent in some parts of India and Africa, the Mediterranean, and South America.

One tooth should be much less challenging and time consuming than working with several front teeth. However, in fact the opposite may often be the case. Changing a single front tooth is a significant cosmetic dentistry challenge from the perspective of the cosmetic dentist.

E. histolytica is a recognized pathogen, although it only causes disease in approximately 10% of the people it infects. E. dispar, on the other hand, is generally considered a non-pathogen. Unfortunately, the two are morphologically indistinguishable, and require isoenzyme, antigen, or molecular methods to distinguish them. The only exception to this is when E. histolytica trophozoites are seen invading the bowel wall on histologic section, or contain ingested RBCs on ova and parasite exam. No ingested RBCs are seen in this case, so it is not possible to differentiate be... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=4025790 Sat, 02 Oct 2010 21:36:21 +0100 4025790 http://www.medworm.com/index.php?rid=4001822&cid=t_100088_155_f&fid=36522&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Fpathtalk%2F%7E3%2FEEmRgrSz4HY%2F2230 Here’s a more straight-forward case than our recent ones: The following object was seen on stool ova and parasite examination and measures approximately 15 micrometers (Modified Trichrome stain, 1000x).

Congratulations to everyone who got this right! Also in the differential would be proglottids of Taenia spp. and artifacts such as onion skin which may be passed relatively intact and mimic tapeworm segments.

This was indeed a case of hepatosplenic T-cell lymphoma (HSTL), gamma-delta type.  Characteristically, lymphadenopathy was absent and there was no peripheral involvement at presentation.  Interestingly, however, the typical intrasinusoidal marrow involvement was a minor feature second to an interstitial process.  Perhaps it was just caught at a progressed stage.  The immunophenotype was fairly typical: CD2+, surface CD3+, CD4-, CD5-, CD7 partial dim, CD8 partial dim, CD16+, and CD56/CD57-.  One reader pointed out that these lymphomas are usually CD4- and... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=3858408 Wed, 11 Aug 2010 21:56:01 +0100 3858408 http://www.medworm.com/index.php?rid=3827355&cid=t_100088_155_f&fid=36522&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Fpathtalk%2F%7E3%2F1lrQt063l1o%2F2122 It’s been a while since I posted an interesting case, but here’s one that I saw in follow-up during my flow cytometry month. The patient is a 44 yo M with a history of end-stage renal disease secondary to hypertensive nephropathy who was awaiting transplant > 2 years and undergoing peritoneal dialysis.  Fatigue and anemia and thrombocytopenia developed in late 2009 and because the anemia was attributed to his renal impairment, the thrombocytopenia was felt to be immune thrombocytopenic purpura (ITP) and he was treated with oral prednisone.  As you might expect, his fatigue persisted – as did the anemia and thrombocytopenia.  In addition, on review of systems in January he complained of drenching night sweats, fevers, a 30# weight loss and occasional nose bleeds.  O... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=3827355 Thu, 05 Aug 2010 15:19:25 +0100 3827355 http://www.medworm.com/index.php?rid=3790791&cid=t_100088_115_f&fid=38592&url=http%3A%2F%2Fwww.radiolopolis.com%2Findex.php%2Fmy-profile%2Fmy-blog%2Fradiology-olympics-opened-honoring-the-movers-shakers-and-smartest-in-radiology-education.html Yes, you heard right: the first Radiology Olympics just opened!Because of the plentitude of excellent cases we are receiving every day we had the idea to create an international educational contest a la "Olympic games". With the Radiology Olympics we intend to honor our "movers and shakers" in Radiology .

The keys to the diagnosis is the clinical history (location in nasal mucosa), exposure history (India), and histopathologic features of a polypoid mass containing mature sporangia (large, thick-walled spherical structures) and smaller internal sporangiospores (daughter cells). The sporangia stain with the fungal stains Gomori methenamine silver (GMS) and periodic acid-Schiff (PAS), and may mimic the appearance of similar appearing fungi such as Coccidiodes immitis (as one viewer suggested) and Chrysosporium spp. (the agent of adiaspiromycosis).

Thanks to everyone who wrote in for this case! This was, admittedly, a tricky case, since it is uncommon to see amastigote-type forms in peripheral blood. The reason these atypical forms were present is because this specimen was grown in culture and then innoculated in peripheral blood (artificial infection). Fortunately, the classic “C-shaped” trypomastigote forms with large kinetoplast were still abundant and allowed accurate identification. Although you wouldn’t expect to see a case like this in nature, this type of preparation may show up on proficiency test (since this material is typically grown in culture). Another important point of this case is that the forms on the thi... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=3679922 Sun, 20 Jun 2010 21:10:40 +0100 3679922 http://www.medworm.com/index.php?rid=3676763&cid=t_100088_117_f&fid=34696&url=http%3A%2F%2Fwww.straightfromthedoc.com%2F50226711%2Fmichael_jacksons_doctor_gets_to_keep_california_license.php Photo CreditLast Monday, a judge ruled that Michael Jackson's doctor - Dr. Conrad Murray - gets to keep his California license. Dr. Conrad Murray was charged with involuntary manslaughter in the June 2009 death (by drug overdose) of Michael Jackson.

Instead, it is a Dermacentor tick, which can transmit Rocky Mountain spotted fever. Unlike I. scapularis, Dermacentor spp. ticks have a “chalise-shaped” anal groove and festoons (not well visible here). The most striking feature of the photographs shown are the markings on the scutum, which also are suggestive of Dermacentor, and not Ixodes spp. ticks. Routine prophylaxis of tick-borne diseases is not generally recommended; instead, you should tell him to monitor himself for symptoms of a tick borne disease (e.g. headache, myalgia, fever, rash, influenza-like illness) and see a physician immediately should any symptoms appear.

You can now go back to work, content in that little tidbit of brain knowledge. Functional magnetic resonance imaging (fMRI) is a fancy name for a brain scan that purportedly measures “brain activity.” What is actually measures is simply changes in blood oxygenation and flow in your brain, which we believe to be directly related to brain activity — but this is an indirect measure at best. It’s not actually measuring “brain activity.” fMRI scans are most often used in research to try and better understand our brains and how other things affect our brains (like mental illness or a specific cognitive activity). So you can imagine the challenges that might be faced when you connect this kind of brain measurement to a legal proceeding...

In this case, the worm was immediately recognizable, and the expression of eggs provided confirmatory identification. There are many other instances, however, when what is received in the clinical parasitology lab is not clearly a worm. This is when the identification of eggs is extremely useful. This is done by the following method: Wearing gloves, the worm is gently ‘prodded’ with a blunt object, such as a sterile wooden applicator stick, to attempt to express eggs from its uterus. It is helpful to have the worm in a small amount of saline or formalin, so that this fluid can then ... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=3490895 Wed, 21 Apr 2010 13:23:55 +0100 3490895 http://www.medworm.com/index.php?rid=3460411&cid=t_100088_155_f&fid=36522&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Fpathtalk%2F%7E3%2F1SddxvHfHh4%2F2020 The following worm was retrieved during a screening colonoscopy near the ileocecal valve: By gently ‘prodding’ the worm with an applicator stick, the following eggs were expressed: Identification?

At this magnification, you can appreciate the presence of siphons by which the larvae breath oxygen from the above the surface of the water. That puts them in the Culicine subfamily, which includes the Culex and Aedes genera. Given that these larvae are in urine, they are most likely Culex spp., since this species can tolerate high levels of organic pollution, and may be found in cess pits, open drains, and pit latrines.

In this “culture” technique, stool is typically placed on a beef extract agar plate and incubated at room temperature. If Strongyloides stercoralis larvae are present, they will move out of the stool specimen, dragging bacteria with them. What we’re actually seeing in this case the bacteria growing in the wake of the moving larva. These “tracks” can be seen using a dissecting microscope, and are typically present 24-48 hours after initial plating. Using a 4x objection, it is also possible to see “furrows” left in the agar by migrating larvae (without associated bacterial colonies) and the worms themselves. Since this was a sputum sample, we were concerned that there was not enough bacteria p... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=3425144 Tue, 30 Mar 2010 23:07:54 +0100 3425144 http://www.medworm.com/index.php?rid=3416166&cid=t_100088_115_f&fid=38592&url=http%3A%2F%2Fwww.radiolopolis.com%2Findex.php%2Fmy-profile%2Fmy-blog%2Fnew-case-gallery-feature-display-radiology-cases-by-diagnosis.html And another feature has been added to Radiolopolis: Display cases by diagnosis.This new feature allows you to browse through our entire case gallery by alphabet.1.

G. intestinalis, G. duodenalis) As many of you guessed, these organisms were most likely picked up in the duodenum when the endoscope was threaded through the small bowel to get access to the pancreatic cyst. I don’t know of any reports where Giardia trophozoites actually inhabited a location other than the intestinal lumen. This is really a beautiful example of the trophozoite morphology, and again, I’d like to thank Dr. Abdel Elhosseiny for this case. The giemsa stain nicely highlights all of the flagella which are not usually seen so clearly in a routine stool Trichrome stain. Thanks to all for writing in with your comments!

As Anonymous mentions, there is both a male and female in the top image. The male is much smaller and has a curved tail. Besides the characteristic location (appendix and cecum), there are several features that allow for identification of these worms. First, the largest worms measure 1 cm or more in length, compared to the smaller 5 mm-long males (although I didn’t give you this information in this case). Second, the females have a distinctive sharply pointed tail (pin-like) that comprises approximately 1/4 of their length. In both sexes, there are lateral alae (cephalic inflations) which are most marked on cross-section (and aren’t easily seen in this case). Finally, they have a distinctive well-defined esophagus which is d... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=3370701 Mon, 15 Mar 2010 23:21:06 +0100 3370701 http://www.medworm.com/index.php?rid=3362469&cid=t_100088_115_f&fid=38592&url=http%3A%2F%2Fwww.radiolopolis.com%2Findex.php%2Fmy-profile%2Fmy-blog%2Fjournal-of-radiology-case-reports-march-2010-issue-published.html The Journal of Radiology Case Reports has just published its March issueVol 4, No 3 (2010)Journal of Radiology Case Reports March 2010 issue Table of ContentsInterventional Radiology (Source: Radiolopolis Blogs) Radiolopolis Blogs blogs http://www.medworm.com/rss/comments.php?id=3362469 Fri, 12 Mar 2010 21:29:30 +0100 3362469 http://www.medworm.com/index.php?rid=3342923&cid=t_100088_155_f&fid=36522&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Fpathtalk%2F%7E3%2FoX_71YA5aLk%2F1978 An inflamed appendix was removed surgically and sent to Surgical Pathology.

Many of you wrote in with suggestions that this is some type of fly larvae, and that is certainly a good thought. However, there are no structures such as spines or mouth parts to confirm this identity, and the history would be a bit odd. Instead, this is actually a proglottid of Dipylidium caninum, the double-pored dog tapeworm. Although classically likened to “grains of rice,” mature and gravid proglottids have been described as “pumpkin seed” shaped (as seen here). The diagnosis is confirmed by identifying the characteristic egg packets of D. caninum. This can be accomplished by gently expressing eggs out of the proglottid using a sterile applicator stick.

Thank you all for the great comments! The eggs shown here are classic for S. mansoni, with their large size (>150 microns largest dimension) and classic lateral spine. Chris C. asked how I thought to do the squash preparation on this tissue. The answer is that this tissue was submitted specifically to look for Schistosoma eggs. As you can imagine, this is a rare request when you practice in an area that does not have endemic schistosomiasis. However, we do on occasion receive rectal biopsies in microbiology for this technique. It’s important that the tissue be sent fresh, since fixed tissue will not squash easily, and does not provide a good preparation.

Dirofilaria spp. cause both subcutaneous and pulmonary infections in humans, with D. immitis being largely responsible for the pulmonary infections in the U.S. and worldwide. In dogs, the adult worms live in the right side of the heart and cause debilitating disease. The adults produce unsheathed larvae which circulate in the blood and are transmitted to other hosts through the bite of an infected mosquito. Humans are accidental hosts that also acquire infection through a mosquito bite. However, the worms cannot live in the human heart and quickly die and are passively transported to the lungs where they wedge in a small vessel and produce an infarct.

A few of you noticed that I gave the answer away on the close up image! Thanks for writing in to let me know and share your thoughts. As you all probably know, this is an extremely rare presentation of pinworm infection. Typically, deposition of eggs by the female work in the perianal skin folds causes intense itching. It is only when the worm and/or eggs ends up in a place where they shouldn’t be (e.g. genital tract, colon diverticulum or fissure) that an abscess can form, and complications arise, such as seen in this case. The diagnosis is made by identifying the characteristic eggs, measuring approximately 50-60 microns in greatest dimension.

Notice the multiply infected RBCs and atypical forms which are characteristic for infection with Babesia spp. Several viewers suggested Plasmodium falciparum as an alternative. This is definitely in the differential diagnosis, since they can both demonstrate high parasitemia, multiply infected RBCs, and small delicate rings on peripheral blood smear. Also, intermediate stages (e.g. schizonts) are almost never seen in P. falciparum infection, and never seen in Babesia infection. This overlap in morphologic features can create quite a challenge in distinguishing the 2 infections.

This is a rare manifestation of disease with the free-living amebae. More commonly, Acanthamoeba spp. cause amebic keratitis – typically in contact lens wearers. However, this organism and B. mandrillaris can rarely gain access to the systemic circulation of immunocompromised (and occasionally immunocompetent) individuals and travel to the brain, where it causes granulomatous amebic encephalitis. The lungs and skin are thought to be primary sites of entry into the body. These amebae can be differentiated from Entamoeba histolytica by the presence of a large karyosome and cysts in tissue. In comparison, E. histolytica has a small central karyosome with uneven rim of clumped chromatin, and it doe... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=3208713 Tue, 26 Jan 2010 04:00:09 +0100 3208713 http://www.medworm.com/index.php?rid=3189432&cid=t_100088_155_f&fid=36522&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Fpathtalk%2F%7E3%2Ft2MGQYpgvlE%2F1886 A patient with recurrent high grade lymphoma on an extensive chemotherapeutic regimen presented with increasing shortness of breath and consolidation on chest radiograph.

This disease is caused by E. histolytica, a protozoan parasite. Most of you recognized the classic “flask shaped” ulcer at low magnification. This type of ulcer is so named because its base is wider than its apex. At higher magnification, numerous trophozoites can be seen at the leading edge of the ulcer. Under oil, the nuclear features are difficult to make out, but you can tell this is the “ring and dot” chromatin pattern or E. histolytica and that there is an ingested RBC in the cytoplasm. Heather mentions that histologic sections are particularly difficult to interpret for parasitologists who are not used to seeing them. That’s definitely true.

This was a tricky case, but the location of the worm helps (colon lumen), and the eggs are diagnostic. Although the eggs are reminiscent of hookworm (as suggested by one viewer), that is largely due to the fact that the cytoplasmic contents of the eggs have retracted from the wall (probably as an artifact of fixation). The thick wall and bipolar plugs are the most useful features.

The eggs measure between 30 to 50 microns in diameter.

In addition, this study examined guidelines for consideration of intelligence test part scores and consideration of the unreliability of IQs through consideration of the standard error of measurement (SEM) or an IQ range. As found in previous studies, results revealed great variation in the specific eligibility guidelines for MR from state to state. The greatest variation appeared to be across the adaptive behavior considerations. Approximately 20% of states (10) recommend consideration of intelligence test part scores, and approximately 39% of states (20) recommend attention to unreliability of IQs through consideration of the SEM...

Like P. vivax, P. ovale has prominent stippling (a.k.a. Schuffner’s dots) and enlargement of the infected red blood cells, but the trophozoite forms are more compact than P. vivax, and many of the infected red blood cells (approximately 1/3) are elongated or oval in shape (hence the name ovale). In addition, one edge of the infected cells is often ragged or fimbriated.

E. granulosus typically produces a single, slowly growing cyst, that may eventually contain one or more daughter cysts – each containing protoscoleces (the so called ‘cysts within a cyst’ appearance) – while E. multilocularis typically produces multiple, rapidly growing cysts that expand in a invasive fashion, and are not constrained by an outer cyst wall. E. multilocularis cysts rarely contain protoscoleces in humans, but are often ’sterile’.

The distinguishing features of this eggs are its large size (>100 microns in length), and characteristic terminal spine. The fact that they are found in urine is another important feature, since these eggs are usually laid around the venus plexus of the bladder, and some eventually make their way through the bladder wall into the urine. What is striking about this case is the associated inflammatory response. Note here how the egg has been badly damaged by the adherent collection of inflammatory cells.

You all recognized that this egg falls into the category of thin-walled oval operculated eggs, which includes (in increasing size) Clonorchis sinensis, Diphyllobothrium latum, Paragonimus westermani, and Fasciola hepatica/Fasciolopsis buski. I put the last 2 eggs together since they are morphologically indistinguishable – although they are from 2 distinct flukes that inhabit different regions of the body. There are subtle differences between these 5 eggs, but they can be easily confused for one another. That is why it is essential to MEASURE your eggs using an ocular micrometer so that an accurate identification can be made. Of interest, these 5 eggs are from 4 flukes and 1 cestode.

Late last night, Orin Kerr at the Volokh Conspiracy sketched out his predictions of whether the individual justices would go for Gura’s main argument: that the indefensible Slaughter-House Cases should be overturned and thus that the Court should “incorporate” the rights at issue via the Privileges or Immunities Clause.  (Cato supports this argument, as we’ll show in the brief we’ll be filing next week.) He concludes that Justice Thomas is the only vote available for this claim.

I was going to call this a Reduvid bug, from the Reduviidae family, which includes “Assassin” or “kissing” bugs. Assassin bugs are the vectors of Chagas disease (Trypanosoma cruzi). There are over 135 species in North America, but fortunately, Chagas disease is limited to the southern most portion of the U.S., and is primarily in Central and South America. However, in showing these photographs to my entomology friends, they comment that this bug may be either a Reduvid bug or one of the leaf-footed bugs (family Coreidae), that has approximately 80 species in N.

As a note – If you see hooklets inside a helminth egg, then you know you are dealing with a cestode. The presence of diagnostic eggs allows for identification to the genus level.

These protozoan parasites are free-living amoebae found widely in the environment, such as in fresh water pools, soil, dust, and even chlorinated tap water. Keratitis usually occurs in patients that wear contact lenses, since the lens provides a nidus for irritation and infection. The classical history is that of a patient who wears contact lenses and rinses them in tap water or home-made saline solution. The diagnosis is made by identifying classic cysts and/or trophozoites in corneal scrapings or biopsies, (histopathology, cytopathology, or microbiology preparations). Acanthamoeba spp. can also be grown in culture or detected using fluorescent and molecular methods. Trophozoites measure approximat... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=2954816 Tue, 03 Nov 2009 15:33:50 +0100 2954816 http://www.medworm.com/index.php?rid=2939441&cid=t_100088_122_f&fid=37835&url=http%3A%2F%2Fwww.iqscorner.com%2F2009%2F10%2Fimportance-of-following-standardized-iq.html Another Atkins MR/IQ court decision revolving around IQ score issues, this time the Stanford-Binet V.  Affidavit provided by SB5 test author.  Oral arguments available to listen to.  The decision should remind all psychologist re: the importance of following standardized testing procedures when administering an intelligence test.  More information at ICDP sister blog.Technorati Tags: psychology, forensic psychology, criminal psychology, criminal justice, psychology and law, Atkins case, MR, mental retardation, intellectual disability, SB5, SB V, Stanford Binet Intelligence test, standardized testing, death penalty, capital punishment (Source: Intelligent Insights on Intelligence Theories and Tests (aka IQ's Corner)) Intelligent Insights on Intelligence Theories and Tests (aka IQ's Corner) blogs http://www.medworm.com/rss/comments.php?id=2939441 Thu, 29 Oct 2009 02:57:00 +0100 2939441 http://www.medworm.com/index.php?rid=2931306&cid=t_100088_155_f&fid=36522&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Fpathtalk%2F%7E3%2FhbNomnkxs1g%2F1746 The following photos are from a Giemsa-stained slide of corneal scrapings from a patient with a painful red eye.

Like amebiasis, the site of infection is typically the large intestine, where it can cause invasive disease, bloody diarrhea, fever, and abdominal pain. This case is a good example of invasive disease with mucosal ulceration (below). Within the ulcer and intestinal mucosa, the large ciliated trophozoites can be seen. The trophozoites are large (typically > 50 microns) and have a vacuolated cytoplasm and a classic dark “kidney-bean” shaped macro-nucleus. These features allow these trophozoites to be distinguished from those of Entamoeba histolytica, which are smaller (20 microns) and have a smaller, less distinctive nucleus.

This is an unusual, but well-documented manifestation of pinworm infection. Typically, the adult worms do not penetrate the intestinal wall; the males pass out with the feces after maturation, while the females remain in the cecum and travel to the anus at night to lay eggs on the perianal skin. However, adult worms and eggs can occasionally get trapped in the intestinal mucosa and cause a suppurative or granulomatous reaction. The diagnostic features include the adult nematode structures (cuticle, gut, musculature) and the classic lateral alae (spines) that are present at all levels of the body (see below). E. vermicularis is the only ... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=2905126 Mon, 19 Oct 2009 15:47:19 +0100 2905126 http://www.medworm.com/index.php?rid=2890956&cid=t_100088_155_f&fid=36522&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Fpathtalk%2F%7E3%2FfTptOLIhYLo%2F1689 Here is an unusual case for you.

The key to the identification is recognizing the small nuclei with large karyosomes in the trophozoites. Note also the classic bubbly cytoplasm. These are characteristic features of the free-living amoebae. The differential diagnosis includes the other free-living amoebae Acanthamoeba spp. and Balamuthia mandrillaris. However, these 2 amoebae are typically seen within brain parenchyma (instead of the CSF) and also produce characteristic cysts (the dormant stage). The history also fits best for infection with N. fowleri, given the rapid state of deterioration in an otherwise healthy boy. Infection with the other two free-living amoebae is typically in immunocompromised adults, and has a subacute or chroni... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=2890957 Wed, 14 Oct 2009 14:07:14 +0100 2890957 http://www.medworm.com/index.php?rid=2871841&cid=t_100088_115_f&fid=38592&url=http%3A%2F%2Fwww.radiolopolis.com%2Findex.php%2Fmy-profile%2Fmy-blog%2Foctober-issue-of-the-journal-of-radiology-case-reports-published.html The Journal of Radiology Case Reports has just published its October issueVol 3, No 10 (2009)Journal of Radiology Case Reports October 2009 issue (Source: Radiolopolis Blogs) Radiolopolis Blogs blogs http://www.medworm.com/rss/comments.php?id=2871841 Wed, 07 Oct 2009 17:45:44 +0100 2871841 http://www.medworm.com/index.php?rid=2871869&cid=t_100088_122_f&fid=37835&url=http%3A%2F%2Fwww.iqscorner.com%2F2009%2F10%2Fiq-profile-variability-and-mr-dx-life.html Readers of IQs Corner will likely find the guest post, by Dr. Dale Watson, a clinical forensic neuropsychologist, regarding the intelligence test interpretation issues in a recent Atkins IQ MR death penalty decision of interest.

Definition: a subcutanteous tumor-like mass caused by the presence of adult filarial worms Onchocerca volvulus. Note the fibrous tissue surrounding the coils of the adult worms, and the microfilariae within the classic ‘double uterus’ and in the surrounding tissue. All adult female filarial worms that infect humans have a classic double uterus, seen best in cross-section. The disease caused by Onchocerca volvulus is called onchocerciasis. The symptoms are caused almost entirely by the release of the microfilariae into the surrounding skin where they cause extremely itchy dermatitis. The most severe damage, however, is caused by the migration of the microfilariae through the chambers of the eye, and the retina, resulting in permanent scarring and blindne... pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=2865934 Tue, 06 Oct 2009 12:45:58 +0100 2865934 http://www.medworm.com/index.php?rid=2855859&cid=t_100088_155_f&fid=36522&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Fpathtalk%2F%7E3%2FkFijciSD6K0%2F1652 The following painless nodule was removed from the subcutaneous skin of the abdomen from an African male.

The first step is to determine if it is a hard or soft tick. Hard ticks transmit the majority of tick-borne diseases (e.g. Lyme disease, Rocky Mountain Spotted Fever, Babesiosis, Ehrlichiosis), although tick-borne relapsing fever is transmitted by soft ticks. To tell them apart, look to see if the head (capitulum) is visible from the dorsal surface (it’s ‘back’). In soft ticks, it is only visible from the ventral surface (underside). Hard ticks also have a hard outer layer called a scutum, which covers either a portion of the dorsal surface (in females) or the entire dorsal surface (males). Shown here is a female hard tick.

Babesiosis is a tick-borne disease, found in North America, Europe, and Asia. It is a mimic of infection with Plasmodium falciparum (which was the 2nd most common answer that viewers gave), since the infected RBCs are not enlarged, the rings are small (1/3 the size of the RBC or smaller), and multiple infections per cell are common. Fortunately, several features allow for differentiation of Babesia spp. from P. falciparum. First, note that the size of the organisms within RBCs is variable, and that some forms are extremely small ( (Source: pathtalk.org) pathtalk.org blogs http://www.medworm.com/rss/comments.php?id=2828472 Thu, 24 Sep 2009 00:37:50 +0100 2828472 http://www.medworm.com/index.php?rid=2800701&cid=t_100088_155_f&fid=36522&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Fpathtalk%2F%7E3%2FBMOAurU-UP4%2F1620 The following images are from a peripheral blood smear from a 93 year old male from Connecticut.

I think that most of us are not used to seeing ticks cut in histologic section (usually this isn’t necessary for identification!), but there are some characteristic features that allow for easy identification of this case. First, notice that the organism is mostly external to the skin, and is inserted only at one end. This is the classic presentation for a tick, and would argue against a botfly larva which is mostly inserted into the skin. In addition, there are useful identifying histologic features as outlined in the image below, including a thick sclerotized cuticle, well-developed skeletal muscle near the mouth parts, and the mouthparts themselves, if present.
