Three Cases of Fatal Acrylfentanyl Toxicity in the United States and a Review of Literature.

Fentanyl analogs pose a unique challenge for forensic pathologists and toxicologists. The extreme potency of these analogs results in minute blood, urine and vitreous concentrations that are technically difficult to identify. This in addition to their absence from standard drug screening may potentiate a setting of apparent drug overdose without an immediately identifiable source.

Cases of transfusion-transmitted babesiosis occurring in nonendemic areas: a diagnostic dilemma.

Background: Transfusion-transmitted babesiosis (TTB) has been rapidly increasing in incidence since the beginning of the 21st century. Asymptomatic individuals with Babesia infection are able to donate blood in the United States because of the lack of specific blood donation testing. Blood products collected in Babesia-endemic areas are distributed nationally; thus, clinicians in nonendemic states may fail to include babesiosis in the differential diagnosis of a patient who had a recent transfusion history and a fever of unknown origin.

Synthetic cannabinoid drug use as a cause or contributory cause of death.

Adverse effects associated with synthetic cannabinoid use include agitation, psychosis, seizures and cardiovascular effects, all which may result in a lethal outcome. We report the collection of data from 25 medical examiner and coroner cases where the presence of synthetic cannabinoids was analytically determined. Participating offices provided case history, investigative and relevant autopsy findings and toxicology results along with the cause and manner of death determination.

Preoperative use of platelets in a 6-year-old with acute appendicitis and a myosin heavy chain 9-related disorder: a case report and review of literature.

Background: Mutations of nonmuscle myosin heavy chain 9 (MYH9) gene are an autosomal dominant cause of inherited thrombocytopenia in children. MYH9 spectrum disorders include May-Hegglin anomaly and Sebastian, Fechtner, and Epstein syndromes. Patients with these disorders often present with macroplatelets and thrombocytopenia and have a mild bleeding tendency; extrahematologic manifestations (nephropathy, deafness, and cataracts) correlate with specific mutations.

The importance of microscopic examination of the lungs in decedents with sustained central intravascular catheters: a nine-case series.

Indwelling intravascular catheters provide convenient access to healthcare personnel and also recreational intravenous drug users who inject suspensions of oral medications. A nine-case series of autopsies of clinically stable decedents with indwelling catheters and sudden death is herein presented. Pulmonary histologic findings were consistent with intravenous administration of oral medications in all cases.

Death due to complications of anhidrotic ectodermal dysplasia.

Ectodermal dysplasia comprises a group of disorders affecting ectodermal tissues. Severity depends on the genetic aberration; hyperpyrexia secondary to absence of sweat glands is a common complication. Treatment is supportive.

The significance of adrenal hemorrhage: undiagnosed Waterhouse-Friderichsen syndrome, a case series.

A retrospective series of five cases of nontraumatic gross adrenal hemorrhage were identified in 800 consecutive forensic autopsies. All patients were males, of different ethnicities and with ages ranging from 2 to 48 years. All patients had a clinical history and autopsy findings suggestive of sepsis.

Fatal granulomatous meningoencephalitis associated to mycobacterium mucogenicum-like microorganism: a case report.

Mycobacterium mucogenicum is rarely associated to human infections. However, in the last year, a few reports of sepsis and fatal cases of central nervous systems have been documented. Here we report a fatal case of granulomatous meningoencephalitis of three weeks of evolution where DNA from a M.

Ileal perforation and reactive hemophagocytic syndrome in a patient with disseminated histoplasmosis: the role of the real-time polymerase chain reaction in the diagnosis and successful treatment with amphotericin B lipid complex.

The following case illustrates an ileal perforation and reactive hemophagocytic syndrome (RHS) resulting from disseminated histoplasmosis in a patient with Human Immunodeficiency Virus (HIV) from Puerto Rico. Although the diagnosis was established by histopathologic findings and a positive bone marrow culture, Histoplasma capsulatum-specific real-time Polymerase Chain Reaction (PCR) allowed to confirm the diagnosis from formalin-fixed, paraffin-embedded tissue. Interestingly, the Histoplasma antigens in both serum and urine samples were falsely negative.
