Mucormycosis, caused by Zygomycetes fungi of the order Mucorales, is a rare opportunistic infection which usually develops in immunosuppressed patients, especially in patients with diabetic acidosis. This infection, associated with the presence of broad, nonseparate hyphae in tissue, originates usually in the perinasal sinuses and nose, orbit, central nervous system, lung, skin, soft tissue, or gastrointestinal tract, but is occasionally disseminated from the primary location to other areas. Recently we experienced a case of Mucormycosis found in the breast of a 70-year old woman undergoing hemodialysis for diabetic nephropathy. The patients was very poor in her systemic condition. On physical examination, we found the subcutaneous mass in the left breast. Breast ultrasonography showed a mass with a relatively clear boundary in subcutaneous fatty layer and excisional biopsy confirmed infiltration of breast tissue by fungal hyphae. With improvement of patient's malnutrition via an aggressive hemodialysis, control of blood glucose and total parentral nutrition, the mass was slightly reduced in size and maintained without causing any notable symptom. Since Mucormycosis found in the breast tissue has not been reported in the literature yet, we report its case observed in a hemodialysis patient for diabetic nephropathy with the review of the literatures.

High-dose intravenous immunoglobulins alter the disease activity of adult-onset Still's disease (AOSD). Because activation status of FcgammaR is possibly dependent on their genetic polymorphisms, we investigated whether the polymorphisms of FcgammaR IIa and IIIa are risk factors, and affect the clinical features of AOSD. Genomic DNA was extracted from 36 patients and from 197 healthy controls. Polymerase chain reaction for FcgammaR IIa and IIIa using the allele-specific primers and direct sequencing of FcgammaR IIIa polymorphic site were performed. The frequencies of FcgammaR IIa/IIIa genotype between patients with AOSD and controls were not different. The allelic frequencies of FcgammaR IIa/IIIa between patients with AOSD and controls were not different, either. However, the FcgammaR IIa-R/R131 genotype was associated with a higher concentration of hemoglobin (p=0.04) and stable liver function (p=0.009) than the other genotypes. The FcgammaR IIIa-F/F176 genotype was associated with significantly lower titers of serum ferritin (p=0.025), and higher serum albumin (p=0.037) and cholesterol (p=0.014) concentrations than the other genotypes. This study suggest that the FcgammaR IIa and IIIa polymorphisms might not be genetic risk factors for AOSD in Korean, but contribute to the activity of disease. FcgammaR IIa-R/R131 and IIIa-F/F176 genotypes, low-binding genotypes for IgG2a and G1, may have more protective effects in acute stage of the disease than the other genotypes.

The granular cell tumor was first described in 1926. Recently, it has been suggested that the tumor is Schwann cell in origin, and this notion has been supported by electron microscopic studies and immunohistochemistry of the S-100 protein. The most frequently involved organs include the tongue, skin, breast, and digestive tract. The esophagus is rarely involved. The treatment of choice for an esophageal granular cell tumor is still controversial. The traditional treatment has been surgical excision, but new therapeutic options, including laser surgery, diathermy loop, and multiple biopsies have recently been tried. An endoscopic esophageal mucosal resection (EEMR) tube, originally designed for resection of early esophageal cancer, is widely used nowadays. A case of a granular cell tumor of the esophagus, which was successfully removed by an EEMR tube, is herein reported.

Cryptococcosis is a systemic fungal infection caused by Cryptococcus neoformans. This mycosis is best known for meningeal involvement, yet, this disease rarely can be limited to the lungs. The usual portal of entry is respiratory tract. The recently rising incidence of the disease can be attributable to wide use of steroid, immunosuppressive agents and advent of AIDS. We experienced one case of pulmonary cryptococcosis in healthy person, who was admitted to the our hospital because of cough. Cryptococcus neoformans was isolated in the sputum, and lung tissue obtained by CT guide needle aspiration biopsy. Clinical improvement was noted after 6weeks of medical therapy with fluconazole.

Active serologic surveillance is necessary to control the spread of the avian influenza virus (AIV). In this study, we evaluated a commercially-available cELISA in terms of its ability to detect AIV antibodies in the sera of 3,358 animals from twelve species. cELISA detected antibodies against reference H1- through H15-subtype AIV strains without cross reactivity. Furthermore, the cELISA was able to detect antibodies produced following a challenge of the AIV H9N2 subtype in chickens, or following vaccination of the AIV H9 or H5 subtypes in chickens, ducks and geese. Next, we tested the sensitivity and specificity of the cELISA with sera from twelve different animal species, and compared these results with those obtained by the hemagglutination-inhibition (HI) test, the "gold standard" in AIV sera surveillance, a second commercially-available cELISA (IZS ELISA), or the agar gel precipitation (AGP) test. Compared with the HI test, the sensitivities and specificities of cELISA were 95% and 96% in chicken, 86% and 88% in duck, 97% and 100% in turkey, 100% and 87% in goose, and 91% and 97% in swine, respectively. The sensitivities and specificities of the cELISA in this study were higher than those of IZS ELISA for the duck, turkey, goose, and grey partridge sera samples. The results of AGP test against duck and turkey sera also showed significant correlation with the results of cELISA (R-value >0.9). In terms of flock sensitivity, the cELISA correlated better with the HI test than with commercially-available indirect ELISAs, with 100% flock sensitivity.

With increase of multi-drug resistant Escherichia coli in community-acquired urinary tract infections (CA-UTI), other treatment option with a therapeutic efficacy and a low antibiotic selective pressure is necessary. In this study, we evaluated in vitro susceptibility of E. coli isolates from CA-UTI to fosfomycin (FM), nitrofurantoin (NI), temocillin (TMO) as well as trimethoprim-sulfamethoxazole (SMX), ciprofloxacin (CIP) and cefepime (FEP). The minimal inhibitory concentrations were determined by E-test or agar dilution method according to the Clinical and Laboratory Standards Institute guidelines, using 346 E. coli collected in 12 Korean hospitals from March 2010 to February 2011. FM, NI and TMO showed an excellent susceptibility profile; FM 100% (346/346), TMO 96.8% (335/346), and NI 99.4% (344/346). Conversely, resistance rates of CIP and SMX were 22% (76/346) and 29.2% (101/349), respectively. FEP still retained an activity of 98.5%. In Korea, NI and TMO in addition to FM are a good therapeutic option for uncomplicated CA-UTI, especially for lower UTI.
