BACKGROUND: Uncovering the correct diagnosis of chronic hypokalemia with potassium (K(+)) wasting from the kidneys or gut can be fraught with challenges. We identified clinical and laboratory parameters helpful for differentiating the causes of chronic hypokalemia. METHODS: Normotensive patients referred to our tertiary academic medical center for the evaluation of chronic hypokalemia were prospectively enrolled over five years. Clinical features, laboratory examinations-including blood and spot urine electrolytes, acid-base status, biochemistries and hormones-as well as genetic analysis were determined...

Spontaneous osteonecrosis of the knee (SONK) is a feared condition of unknown cause, in its classic form appearing in the medial femoral condyle in middle-aged or elderly subjects. Diagnosis with radiography is notoriously difficult with a long latency before typical changes appear. Magnetic resonance imaging (MRI) is regarded as a diagnostic tool with the possibility to give an earlier diagnosis with improved chances for treatment. However, also with MRI there may be an initial diagnostic blind spot before typical changes appear...

BACKGROUND: Nasopharyngeal carcinoma (NPC) is a major head and neck cancer with high occurrence in Southeast Asia and southern China. We aimed to identify autoantibodies that may contribute to early detection of NPC. METHODS: We used serological proteome analysis to identify candidate autoantibodies against tumor-associated antigens. Levels of autoantibodies and Epstein-Barr virus capsid antigen-IgA (VCA-IgA) were measured by ELISA in 129 patients with NPC and 100 normal controls...

In Brazil, two pathogenic Rickettsia species have been identified causing tick-borne spotted fever (SF). The aetiological agent Rickettsia rickettsii causes serious illness, particularly in the south-eastern region of the country. Moreover, the Rickettsia sp. strain Atlantic Rainforest cause milder clinical manifestations in south-eastern, south and north-east regions. This study has sought to analyse predictive factors for fatal SF. A case-control study was performed using disease notification records in Brazil...

The use of saliva and dried blood spots (DBS) could increase access to HCV diagnosis for high-risk populations, such as HIV-infected individuals, but the performance of these assays has not been well established in this group. This study aims to evaluate HIV status, particularly TCD4(+) cell count and viral load, in the performance of anti-HCV testing using DBS and saliva. A total of 961 individuals classified as HCV + , HIV+ or HIV/HCV + , as well as negative controls, donated serum, DBS and saliva samples for anti-HCV testing using a commercial enzyme immunoassay...

BACKGROUND: Long noncoding RNAs (lncRNAs) have been suggested to be biomarkers for diagnosis and prognosis of sporadic colorectal cancer. AIMS: This study aimed to characterize the expression profile of lncRNAs in DNA mismatch repair-proficient (pMMR) early-stage colon cancer (CC). METHODS: The microsatellite instability (MSI) status was examined by a multiplex PCR. The expression of lncRNA and mRNA was analyzed by microarrays. The differentially expressed lncRNAs and mRNAs were determined by bioinformatic analyses and validated in 44 CC samples and 32 non-tumor colonic specimens by quantitative real-time polymerase chain reaction (qRT-PCR)...

Esophageal tuberculosis is rare, even in countries with high prevalence of tuberculosis. It usually presents as an ulcerative lesion on conventional endoscopy. Due to its rarity, when esophageal tuberculosis presents as a subepithelial lesion (SEL), conventional endoscopy and other imaging modalities such as computed tomography (CT) are often insufficient to distinguish it from other diseases. From January 2007 to December 2014, 1094 patients who underwent endoscopic ultrasonography (EUS) were retrospectively analyzed...

An increase in endotoxin concentration in the bloodstream can trigger activation of innate immune response leading to septic shock. There is currently no method available for rapid endotoxin detection at a patient's bedside. We demonstrate a simple, portable and cost-effective strategy to measure endotoxin levels in human serum within 5min using a flow-through assay. A drop of serum containing LPS was spotted on an endotoxin-affinity membrane placed over high-wicking absorbent pads. Subsequent addition of polymyxin B sulfate drug-conjugated gold nanoparticles allowed concentration-dependent visualization of spots by the naked eye in the clinically-relevant range of 10pg/mL to 10ng/mL...

The issue of antibody responses to tumors is potentially important to cancer immunologists. Early detection of cancer represents one of the most promising approaches to reduce the growing cancer burden. Natural immunoglobulin (Ig)M antibodies have been associated with the recognition and elimination of cancerous and precancerous cells. Using natural IgM antibodies, the present study identified a set of antigens in healthy mice from three different strains and examined whether the global patterns of antibodies are able to discriminate between a condition of more or less susceptibility to breast cancer...

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne infectious disease caused by the SFTS virus (SFTSV). The aim of this study was to clarify whether SFTS is potentially mis-diagnosed as rickettsioses, including spotted fever, typhus fever, and scrub typhus, which are also tick-borne disease. A total of 464 serum samples collected from 222 patients with clinically suspected rickettsiosis between 1999 and 2012 were tested for antibodies against the SFTSV. Of the 464 serum samples, one was positive for antibodies against the virus in an enzyme-linked immunosorbent assay and indirect immunofluorescence assay...

BACKGROUND: Many different intestinal parasite species can co-occur in the same population. However, classic diagnostic tools can only frame a particular group of intestinal parasite species. Hence, one or two tests do not suffice to provide a complete picture of infecting parasite species in a given population. The present study investigated intestinal parasitic infections in Beira, Mozambique, i.e. in the informal settlement of Inhamudima. Diagnostic accuracy of five classical microscopy techniques and real-time PCR for the detection of a broad spectrum of parasites was compared...

The tumor necrosis factor (TNF) family ligand ectodysplasin A (EDA) is produced as 2 full-length splice variants, EDA1 and EDA2, that bind to EDA receptor (EDAR) and X-linked EDA receptor (XEDAR/EDA2R), respectively. Inactivating mutations in Eda or Edar cause hypohidrotic ectodermal dysplasia (HED), a condition characterized by malformations of the teeth, hair and glands, with milder deficiencies affecting only the teeth. EDA acts early during the development of ectodermal appendages-as early as the embryonic placode stage-and plays a role in adult appendage function...
