BACKGROUND: Adenovirus is a common pathogen of acute upper respiratory infection in children and is generally self-limiting. Severe adenovirus infections have been reported in immunocompromised hosts especially bone marrow transplantation recipients due to hematologic malignancy. Severe adenovirus pneumonia in immunocompetent hosts has rarely been reported and optimal treatment has not been established. We report a case of community-acquired severe adenovirus pneumonia which was successfully treated with early administration of oral ribavirin...

Human granulocytic anaplasmosis (HGA) is a tick-borne rickettsial zoonosis with fever, thrombocytopenia, and leukopenia. HGA has been reported in Korea in 2013 but it is uncertain how long it has existed. A retrospective study was conducted on patients who underwent bone marrow examination due to fever and cytopenia, with no clear hematologic or microbiologic causes, from 2003 through 2012. Laboratory diagnosis was made by detecting 16S rRNA genes of Anaplasma phagocytophilum from the stored blood samples. Among the 70 patients, five (7...

BACKGROUND: In clinical practice, laboratory results are often important for making diagnostic, therapeutic, and prognostic decisions. Interpreting individual results relies on accurate reference intervals and decision limits. Despite the considerable amount of resources in clinical medicine spent on elderly patients, accurate reference intervals for the elderly are rarely available. The SENIORLAB study set out to determine reference intervals in the elderly by investigating a large variety of laboratory parameters in clinical chemistry, hematology, and immunology...

Photo-thermal angular light scattering (PT-AS) is a novel optical method for measuring the hemoglobin concentration ([Hb]) of blood samples. On the basis of the intrinsic photothermal response of hemoglobin molecules, the sensor enables high-sensitivity, chemical-free measurement of [Hb]. [Hb] detection capability with a limit of 0.12 g/dl over the range of 0.35 - 17.9 g/dl has been demonstrated previously. The method can be readily implemented using inexpensive consumer electronic devices such as a laser pointer and a webcam...

Bone marrow (BM) aspirates used for flow-cytometry (FCM) studies are usually obtained from a second aspiration, as the primary aspirate is used for morphological assessment. For this reason, the FCM samples unavoidably contain some blood; although, good-quality samples contain only a small amount. It is of utmost importance to assess the quality of samples prior to FCM analysis; yet, contamination with peripheral blood (PB) is not evaluated in most laboratories, possibly because the methods available are either qualitative or too complex for daily practice...

We report the case of a 42-year-old man with a 5-year history of myelodysplastic syndrome and photosensitivity who had developed painful erythema and blisters on sun-exposed sites. Histological examination of a mildly lichenified lesion on the dorsal finger revealed extensive deposits of a hyaline-like, periodic acid-Schiff-positive material around superficial dermal blood vessels. Laboratory tests showed elevated erythrocyte protoporphyrin and normal urinary porphyrins, suggesting a diagnosis of erythropoietic protoporphyria...

Hemophagocytic lymphopcytosis (HLH) is a life-threatening condition. It can occur either as primary form with genetic defects or secondary to other conditions, such as hematological or autoimmune diseases. Certain triggering factors can predispose individuals to the development of HLH. We report the case of a 25-year-old male patient who was diagnosed with HLH in the context of adult-onset Still's disease (AOSD) during a primary infection with Epstein-Barr virus (EBV). During therapy with anakinra and dexamethasone, he was still symptomatic with high-spiking fevers, arthralgia, and sore throat...

INTRODUCTION: To provide target values for the manufacturers' survey of the Japanese Society for Laboratory Hematology (JSLH), accurate standard data from healthy volunteers were needed for the five-part differential leukocyte count. To obtain such data, JSLH required an antibody panel that achieved high specificity (particularly for mononuclear cells) using simple gating procedures. We developed a flow cytometric method for determining the differential leukocyte count (JSLH-Diff) and validated it by comparison with the flow cytometric differential leukocyte count of the International Council for Standardization in Haematology (ICSH-Diff) and the manual differential count obtained by microscopy (Manual-Diff)...

Xanthogranuloma is a benign, non-Langerhans cell histiocytosis primarily diagnosed in infants and children, although a subset occurs in adults. Multifocal eruptive presentation of xanthogranuloma is very rare with only four previous cases reported in the literature to our knowledge. We describe a case of eruptive xanthogranuloma in a 49-year-old man who presented with sudden onset of numerous asymptomatic, red-yellow to orange papules on the face, scalp, axilla, flank, and scrotum. Histologic features were consistent with xanthogranuloma with diffuse mixed infiltrate of foamy histiocytes, Touton giant cells, and lymphocytes...
