Reston virus causes severe respiratory disease in young domestic pigs

Reston virus (RESTV), an ebolavirus, causes clinical disease in macaques but has yet only been associated with rare asymptomatic infections in humans. Its 2008 emergence in pigs in the Philippines raised concerns about food safety, pathogenicity, and zoonotic potential, questions that are still unanswered. Until today, the virulence of RESTV for pigs has remained elusive, with unclear pathogenicity in naturally infected animals and only one experimental study demonstrating susceptibility and evidence for shedding but no disease. Here we show that combined oropharyngeal and nasal infection of young (3- to 7-wk-old) Yorkshire cross pigs with RESTV resulted in severe respiratory disease, with most animals reaching humane endpoint within a week. RESTV-infected pigs developed severe cyanosis, tachypnea, and acute interstitial pneumonia, with RESTV shedding from oronasal mucosal membranes. Our studies indicate that RESTV should be considered a livestock pathogen with zoonotic potential.

Reston virus (RESTV) was discovered in 1989/1990 in macaques imported into the United States from the Philippines for research purposes (1). Since then, there have been several episodes of disease caused by RESTV in macaques and rare asymptomatic infections in humans (2, 3). Unexpectedly, in 2008, RESTV emerged in pigs in the Philippines, and, shortly thereafter, RESTV sequences were detected in Chinese swine, raising zoonotic and food safety concerns (4, 5). RESTV constitutes a separate species in the genus Ebolavirus, family Filoviridae, and is generally thought of as the human apathogenic filovirus (6). Aside from humans (2, 3), RESTV has been shown to naturally and experimentally infect macaques, swine, ferrets, bats, and several rodent species (4, 5, 7–13). Upon experimental infection, macaques and ferrets, as well as immunocompromised rodents, such as STAT-1 knockout mice, develop severe disease with lethal outcome, whereas immunocompetent rodents generally do not (9–12). Whether RESTV itself causes disease in naturally infected domestic pigs remains unknown, since the RESTV-infected pigs from the Philippines were coinfected with the virulent arterivirus porcine reproductive and respiratory syndrome virus (PRRSV; now Betaarterivirus suid 1). In an initial experimental study, domestic pigs infected with RESTV only exhibited subclinical infections with evidence for virus shedding (7). We studied RESTV infection in young (3- to 7-wk-old) Yorkshire cross pigs, a swine breed used frequently in commercial pig production systems around the world. The main objective was to determine an age-dependent susceptibility to infection.     

Salivary gland hyalinizing clear‐cell carcinoma with cutaneous metastasis: A rare and deceptive tumor

Clear‐cell carcinoma (CCC) is an uncommon malignant tumor of minor salivary glands. It characteristically has a low‐grade morphology and a favorable outcome by most reports. An EWSR1‐ATF1 fusion can be detected in the majority of cases. We present a rare case of CCC, which had an aggressive course with the development of cutaneous metastases. Practicing dermatopathologists should be aware of this tumor given its low‐grade appearance and histopathologic resemblance to other primary cutaneous adnexal and metastatic neoplasms.

Panniculitis in a 3‐year‐old child with Fanconi anemia‐associated bone marrow hypoplasia heralds transformation to acute myeloid leukemia

Fanconi anemia is a rare, autosomal recessive genomic instability disorder characterized by congenital limb anomalies, panmyelopathy and a high risk of malignancy, principally acute myeloid leukemia. Hematologic malignancy presenting with acute febrile neutrophilic dermatosis (Sweet syndrome), both deep and superficial forms, is well described in Fanconi anemia patients but is a rare phenomenon in otherwise healthy children. We present a case of panniculitis (presumptive subcutaneous Sweet syndrome) heralding transformation to acute myeloid leukemia in a 3‐year‐old boy with a severe Fanconi anemia phenotype.
