Disseminated adenovirus infections (d-ADV) after hematopoietic cell transplant (HCT) are often fatal with limited treatment options. Brincidofovir (BCV) a lipid ester of cidofovir is developed for this indication. We report four pediatric HCT recipients with d-ADV treated successfully with BCV.

Tumor incidence in wild mammals is reportedly very low. Wild nutria, a large rodent, is known to carry many infectious diseases, but rarely exhibits neoplastic diseases. We necropsied a male wild nutria and found a large nodular mass in the left inguinal region, adjacent to the penis. Histopathologically, the mass was diagnosed as preputial gland adenoma. Spontaneous preputial gland adenomas are extremely rare in all animals. Moreover, reports of tumors in nutrias have been limited to adenocarcinomas of the lungs and uterus, as well as subcutaneous fibromas. Here, we describe preputial gland adenoma in a wild nutria.

A total of 44 adult or juvenile nutrias were necropsied for disease survey. A large nodule was found in the liver of a nutria. The histopathological specimen of the hepatic nodule was microscopically examined, and sectional worms were found in the bile duct. The worms showed a tegument with spines, highly branches of vitelline glands and intestine. Finally, we histopathologically confirmed fascioliasis in a wild nutria. In the present study, a case of fascioliasis in a wild nutria is first confirmed in Korea.

The advent and wide use of antibiotics have decreased the incidence of deep neck infection. When a deep neck infection does occur, however, it can be the cause of significant morbidity and death, resulting in airway obstruction, mediastinitis, pericarditis, epidural abscesses, and major vessel erosion. In our clinic, a patient with diffuse chronic osteomyelitis of mandible and fascial space abscess and necrotic fasciitis due to odontogenic infection at the time of first visit came. We successfully treated the patient by early diagnosis using contrast-enhanced CT and follow up dressing through the appropriate use of radiographic images.

OBJECTIVES: To investigate the differences in accessing regional hospitals and the utilization rate of hospitals located in other regions for cancer patients by regions. METHODS: Data for the utilization of regional hospitals for cancer patients were obtained from the Korean National Cancer Incidence Databases in 1999 and 2002. We divided the regions into 16 provinces by administrative districts. We using the SAS 9.1.3 to analyze difference of regional self-sufficiency and the Arcview 3.2 to show in a schematize for regional variation of the regional self-sufficiency. RESULTS: There were regional variations in the regional self-sufficiency of cancer patients. Especially, Jeollanam-do(1999 13.6%, 2002 12.8%), Gyeongsangbuk-do(1999 22.0%, 2002 20.7%), and Chungcheongnam-do(1999 27.8%, 2002 27.1%) had low regional self-sufficiency. The regional self-sufficiency in Gyeonggi-do and utilization rate of cancer patients who lived in other regions were increased between 1999 and 2002(regional self-sufficiency: 1999 37.2%, 2002 48.2%). CONCLUSION: The results of this study showed that there were regional variation in utilization of regional hospitals for cancer patients. Accessibility of cancer patients in metropolitan areas was higher than in small size cities, medium size cities, and rural county areas. These results suggested that it should be considered support medical facilities for cancer patients in rural areas where have lower relevance rate.

Multiple myeloma (MM) is a malignant disease caused by an abnormal proliferation of plasma cells, of which the prognostic factors include chromosomal abnormality, β-2 microglobulin, and albumin. Recently, the term chromothripsis has emerged, which is the massive but highly localized chromosomal rearrangement in response to a one-step catastrophic event. Many studies have shown an association of chromothripsis with the prognosis in several cancers; however, few studies have investigated it in MM. Here, we studied the association between chromothripsis-like patterns and treatment resistance or prognosis. First, we analyzed nine MM cell lines (U266, MM.1S, RPMI8226, KMS-11, KMS-12-BM, KMS-12-PE, KMS-28-BM, KMS-28-PE, and NCI-H929) and bone marrow samples of four patients who were diagnosed with MM by next-generation sequencing-based copy number variation analysis. The frequency of the chromothripsis-like pattern was observed in seven cell lines. We analyzed the treatment-induced chromothripsis-like patterns in KMS-12-BM and KMS-12-PE cells. As a result, breakpoints and chromothripsis-like patterns were increased after drug treatment in the relatively resistant KMS-12-BM. We further analyzed the patients’ results according to the therapeutic response, which was divided into sensitive and resistant, as suggested by the International Myeloma Working Group. The chromothripsis-like pattern was more frequently observed in the resistant group. In the sensitive group, the frequency of the chromothripsis-like pattern decreased after treatment, whereas the resistant group showed increased chromothripsis-like patterns after the treatment. These results suggest that the chromothripsis-like pattern is associated with treatment response in MM.

BACKGROUND: In general, internal/external quality control of special stains for diagnosis of hematological diseases may be unavailable in a clinical laboratory owing to the lack of an appropriate positive/negative control material. METHODS: We developed a protocol on positive/negative control materials for five special stains (iron, myeloperoxidase [MPO], periodic acid-Schiff [PAS], Sudan black B [SBB], and alpha-naphthyl acetate esterase [ANAE]) using a hematological malignant cell line. First, we compared stainability of seven cell lines (HL-60, THP-1, K562, Kasumi-1, KG-1, KO52, and NKM-1), then confirmed duration of stable stainability. A proficiency test using external quality control materials was conducted at eleven institutions, which participated voluntarily. RESULTS: HL-60 and THP-1 cell lines, which showed good stainability among the seven cancer cell lines, were selected as external quality control materials. The stainability of a prepared cell line fixed on control slides was stable for 3–4 weeks (MPO, SBB, and PAS) or 9–10 weeks (ANAE). The stainability of paraffin-embedded control material for iron stain was stable for 3 months. The results from 11 institutions were the same on iron, MPO, SBB, and ANAE. Nevertheless, two of 10 institutes showed discrepant results on PAS. CONCLUSIONS: In this study, we demonstrated that cell lines could serve as a standard quality control material for special stains. Most institutions showed representative results on special stains except for PAS. This protocol for special stain may be useful as an external or internal quality control in a haematology laboratory.
