Q fever is a zoonotic infection caused by Coxiella burnetii. Acute Q fever usually develops as a self-limited flu-like illness, atypical pneumonia, or hepatitis. We experienced a case of Q fever in a 50-year-old male who had a prolonged fever. The bone marrow and lymph node biopsy revealed fibrin-ring granulomas, which is a distinct finding of Q fever. The diagnosis was proven by high titers of C. burnetii anti-phase II antibody (IgM 1:512 and IgG >,048) and positive nested PCR for the com-1 gene. Q fever is rare in Korea, but should be considered in the differential diagnosis of fever of unknown origin

Nocardiosis is well-known opportunistic infection in immunocompromised patients. The timely diagnosis and treatment, however, is still a difficult problem. Recently, as newer molecular techniques, particularly 16S rRNA sequencing, are implemented, the diagnosis and management of the infection are improving. We report a case of lung abscess in a 39-year-old-man who underwent kidney transplantation. He was diagnosed of Nocardia elegans by 16S rRNA sequencing and was cured of the infection with appropriate antibiotic therapy.

It is possible to compare three-dimensional image of patterned injury in virtual space with object using 3D/CAD supported photogrammetry(FPHG). this method make it possible to examine patterned injuries of skin, soft tissue and bone for matching instruments in shape, size and angle without altering. Generally, 3D measuring of objects require 3D digitizer or series of photographs taking by metric camera. We developed program which calibrate pictures taken by non-calibrated commercial camera and un distorted image. This image and objet model n can be examined with respect to matching shapes using 3D/CAD system.

Listeria monocytogenes is a facultative anaerobic gram positive rod bacteria that is wide spread in the natural environment and found in soil, water, decaying vegetation, and as part of the fecal flora of many mammals. It is also a common cause for meningoencephalitis and bacteremia in at-risk groups including neonates, pregnant women, elderly persons, and immunocompromised patients. However, pneumonia with pleuritis is a very rare manifestation of L. monocytogenes. We report a case of pneumonia with pleural effusion caused by L. monocytogenes as isolated from the blood culture of a patient diagnosed with acute lymphoblastic leukemia resulting from induction chemotherapy. The patient recovered after the introduction of therapeutic thoracentesis and administration of intravenous ampicillin (2 g q 6 hr) plus gentamicin (1.7 mg/kg q 8 hr) over a two week period. This case demonstrated that L. monocytogenesis infection should be a consideration in the differential diagnosis of pneumonia and pleuritis in leukemic patients.

The dynamic nature of coronavirus disease 2019 (COVID-19) pandemic requires us to be efficient and flexible in resource utilization. The strategical preparedness and response actions of the healthcare system are the key component to contain COVID-19 and to decrease its case fatality ratio. Depending on the epidemiological situation, each medical institution should systematically share the responsibility for patient screening, disposition and treatment according to clinical severity. To overcome fast-paced COVID-19 pandemic, the government should be rapidly ready and primed for action according to the specific transmission scenario.

BACKGROUND/AIMS: Cytomegalovirus (CMV) surveillance and preemptive therapy is a widely-used strategy for preventing CMV disease in transplant recipients. However, there are limited data on the incidence and patterns of CMV disease during the preemptive period. Thus, we investigated the incidence and pattern of tissue-invasive CMV disease in CMV seropositive kidney transplantation (KT) and hematopoietic stem cell transplantation (HCT) recipients during preemptive therapy. METHODS: We prospectively identified patients with tissue-invasive CMV disease among 664 KT (90%) and 496 HCT (96%) recipients who were D+/R+ (both donor and recipient seropositive) during a 4-year period. RESULTS: The incidence rates of CMV disease were 4.1/100 person-years (4%, 27/664) in KT recipients and 5.0/100 person-years (4%, 21/496) in HCT recipients. Twenty-six (96%) of the KT recipients with CMV disease had gastrointestinal CMV, whereas 17 (81%) of the HCT recipients had gastrointestinal CMV and 4 (19%) had CMV retinitis. Thus, CMV retinitis was more common among HCT recipients (p = 0.03). All 27 KT recipients with CMV disease suffered abrupt onset of CMV disease before or during preemptive therapy; 10 (48%) of the 21 HCT recipients with CMV disease were also classified in this way but the other 11 (52%) were classified as CMV disease following successful ganciclovir preemptive therapy (p < 0.001). CONCLUSIONS: The incidence of CMV disease was about 4% in both KT and HCT recipients during preemptive therapy. However, CMV retinitis and CMV disease as a relapsed infection were more frequently found among HCT recipients.

BACKGROUND: Mucormycosis is an uncommon and life-threatening fungal infection. The clinical predictors of outcome were evaluated in patients with invasive mucormycosis. MATERIALS AND METHODS: We retrospectively reviewed histologically proven cases of invasive mucormycosis in our institution from 1996 to 2012. RESULTS: A total of 64 patients were analyzed. The median age was 59 years (interquartile range [IQR], 50-67), and 32 patients (50%) were male. The most common underlying diseases were diabetes mellitus (67%), hematologic malignancy (22%), and solid cancer (19%). The most common infection sites were the rhino-orbito-cerebral area (56%) and the lungs (31%). The 180-day all-cause mortality was 33%. Disseminated infection was associated with increased mortality (hazard ratio [HR]: 169.74, 95% confidence interval [CI]: 6.41 to 4492.64; P = 0.002). Pulmonary infection (HR: 0.08, 95% CI: 0.01 to 0.66; P = 0.02) and complete surgical removal of infected tissue (HR: 0.12, 95% CI: 0.02 to 0.64; P = 0.01) were associated with decreased mortality. CONCLUSIONS: These results suggest that patients with mucormycosis had a lower risk of mortality if they developed a pulmonary infection, rather than a disseminated infection and with complete debridement of infected tissue.
