Nematode epibionts on skin of the Florida manatee, Trichechus manatus latirostris.

A survey for the presence of nematodes on the skin of the native Florida manatee, Trichechus manatus latirostris from Crystal River, Florida was conducted during annual manatee health assessments. A putative isolate of Cutidiplogaster manati (Diplogastridae) and two other nematodes belonging to the same family were recovered from mid-dorsal tail skin-scrapings from all sampled winter-collected healthy wild adult manatees during two successive years (2018-2019). Qualitative abundance estimates of these three species of diplogastrid nematodes suggest that an average wild Florida manatee adult might possess between 30,000 and 120,000 nematodes on its tail dorsum and that the entire body dorsum including the tail might possess 160,000-640,000 nematodes in roughly equal ratios.

PREFLEDGING MORTALITY AND THE ABUNDANCE OF MOSQUITOES BITING NESTLING BARN OWLS () IN FLORIDA, USA.

Mosquito-borne diseases can have disastrous effects on avian populations; therefore, most studies of bird and mosquito interactions have focused on the mortality and morbidity associated with the diseases. However, the effect of mosquitoes feeding on birds, independent of disease, has not been well studied. We studied Barn Owls () nesting in artificial nest boxes in sugarcane () fields in Florida, US.

A Push-pull Protocol to Reduce Colonization of Bird Nest Boxes by Honey Bees.

Introduction of the invasive Africanized honey bee (AHB) into the Neotropics is a serious problem for many cavity nesting birds, specifically parrots. These bees select cavities that are suitable nest sites for birds, resulting in competition. The difficulty of removing bees and their defensive behavior makes a prevention protocol necessary.

Anti-GBM Disease in Pregnancy: Acute Renal Failure Resolved After Plasma Exchange, Hemodialysis, and Steroids.

Antiglomerular basement membrane (GBM) disease presenting during pregnancy is uncommon. We present a case of a pregnant female who presented with acute renal failure requiring dialysis due to anti-GBM disease. She responded well to plasma exchange, high-dose steroids, and hemodialysis.

Anti-GBM of Pregnancy: Acute Renal Failure Resolved after Spontaneous Abortion, Plasma Exchange, Hemodialysis, and Steroids.

Antiglomerular basement membrane disease presenting during pregnancy is very uncommon. We present a case of a pregnant female who presented with acute renal failure needing dialysis from Goodpasture's disease. She responded very well to just plasma exchange, high dose steroids, and hemodialysis.

Intravascular large B-cell lymphoma with hemophagocytic syndrome (Asian variant) in a Caucasian patient.

Intravascular lymphoma is an aggressive and extremely rare extranodal lymphoma with neoplastic lymphoid cells confined exclusively within intravascular spaces. The histopathologic findings are subtle due to the rarity of the neoplastic cells in blood vessels. Clinical presentations are non-specific and focal space-occupying lesions or lymphoadenopathy are always lacking.

Successful management of gelatinous transformation of the bone marrow in anorexia nervosa with hematopoietic growth factors.

Serous atrophy or gelatinous transformation of the bone marrow (GMT), often seen with severe nutritional deprivation in Anorexia Nervosa (AN), is characterized by hypocellularity and patchy or diffuse replacement of the bone marrow with hyaluronic acid-like mucopolysaccharide material. Treatment with nutritional support alone is often temporary due to the relapsing nature of AN. We present the case of a patient with pancytopenia due to GMT who had multiple prior hospitalizations for infections and blood transfusions.

A novel subtelomeric translocation t(5;9) and a deletion of the RB1 gene in a patient with acute myeloid leukemia (AML-M0).

No chromosomal rearrangements have been identified as specifically associated with minimally differentiated acute myeloid leukemia (AML-M0). Several research groups studied the cytogenetic features of AML-M0 and found that as much as 81% of patients with AML-M0 had chromosomal rearrangements; primarily -5/5q- and/or -7/7q- deletions or translocations involving 12p. A patient, who was diagnosed with AML-M0 eighteen months ago, was referred for cytogenetic evaluation for possible AML relapse.

Vitamin C-induced hyperoxaluria causing reversible tubulointerstitial nephritis and chronic renal failure: a case report.

Unlabelled: Vitamin C is a precursor of oxalate and promoter of its absorption, potentially causing hyperoxaluria. Malabsorption causes Calcium (Ca) chelation with fatty acids, producing enteric hyperoxaluria.

Case: A 73-year-old man with both risk factors was hospitalized with serum creatinine of 8.

Panniculitis: a presenting manifestation of disseminated histoplasmosis in a patient with rheumatoid arthritis.

We report a case of histoplasma panniculitis in a patient with rheumatoid arthritis treated with multiple immunosuppressive agents including infliximab. The patient presented with erythematous plaques involving the right upper anterior abdominal wall, the right flank and later extension to involve the left flank and the left axilla. The histopathologic examination of these lesions was consistent with lobular panniculitis and the cultures of these lesions and blood grew Histoplasma capsulatum.

Trisomy 1q in a patient with severe aplastic anemia.

Aplastic anemia is a rare, serious disease characterized by hypocellular bone marrow and pancytopenia in the peripheral blood. Most cases are acquired, idiopathic, and without gross cytogenetic abnormalities. A few chromosome abnormalities have recurred among a small subset of patients, most commonly trisomy 8 and monosomy 7.

Marginal zone B-cell lymphoma of the uterus: a case report and review of the literature.

We report here a case of a 52-year-old female in whom immunohistological studies of the uterus established a diagnosis of extranodal marginal zone B-cell lymphoma. Malignant lymphoma arising from mucosa-associated lymphoid tissue (MALT) of uterus is extremely rare. Accurate histologic interpretation of uterine lymphoma is essential, as treatment options and prognosis vary based on the histological grade of such lymphomas.

Acute promyelocytic leukemia and constitutional trisomy 21.

The incidence of acute myelogenous leukemia (AML) in patients with constitutional trisomy 21 is estimated to be 1 in 300; it is usually seen before age four. Clinical and epidemiological data confirm the improved life expectancy of patients with Down syndrome and their increased susceptibility to the development of leukemia, among other cancers. The most frequent subtype of AML associated with Down syndrome is acute megakaryoblastic leukemia (FAB: M7).

A variant t(8;10;21) in a patient with pathological features mimicking atypical chronic myeloid leukemia.

We report the case of an 11-year-old girl who was initially diagnosed with a chronic myeloproliferative disorder, possibly chronic myelogenous leukemia (CML), based on laboratory and blood and marrow morphological findings. The patient's high leukocyte count did not respond to hydroxyurea, a standard initial therapy for CML. Chromosomal analysis revealed that the patient did not have t(9;22), but a complex t(8;10;21)(q22;q24;q22), a variant of t(8;21).

Remission of natural-killer cell lymphoma of the liver with anti-hepatitis C therapy.

Non-Hodgkin lymphomas (NHL) consist of a diverse group of lymphoproliferative neoplasms with unique patterns of biology, behavior, and differing responses to therapy. A rare subtype of malignancy arising from cells of putative natural killer (NK) origin is being recognized as a distinct clinicopathological entity. Viruses including hepatitis C have been reported in association with various types of NHL but not the NK-cell subtype.

Granulocytic sarcoma presenting with malignant anasarca in a patient with secondary acute myeloid leukemia.

Granulocytic sarcomas (GS) are rare extramedullary tumor masses composed of immature cells derived from the hematopoietic myeloid series. GS occur in 3% to 7% of cases of acute myeloid leukemia (AML) and can present before, during, or even after the diagnosis of AML. GS can involve different organs, individually or simultaneously, including the skin, lymph nodes, bone, breast, central nervous system, and lung among others.

Identification of t(15;17) and a segmental duplication of chromosome 11q23 in a patient with acute myeloblastic leukemia M2.

A 32-year-old man was newly diagnosed with acute myelocytic leukemia, classified as acute myeloblastic leukemia with maturation (AML-M2) according to the French-American-British classification system. Conventional chromosome analysis before chemotherapy treatment revealed an abnormal karyotype: a possible segmental duplication of 11q23, plus a translocation between chromosomes 15 and 17 [t(15;17) (q22;q21.1)] in the majority of cells analyzed.

Duplication 15q as the sole anomaly in an acute promyelocytic leukemia patient without t(15;17).

We present a unique chromosomal abnormality found in a patient with acute myeloblastic leukemia of French-American-British subtype M3. The patient was referred for an evaluation of a chromosomal anomaly exclusively associated with FAB M3 or acute promyelocytic leukemia: a translocation between chromosomes 15 and 17, t(15;17)(q22;q21.1).
