Prostatic involvement is common in men with melioidosis. Indeed, some clinicians recommend radiological screening of all male patients as an undrained prostatic abscess may result in relapse of this potentially fatal disease. However, sophisticated medical imaging is frequently unavailable in the remote and resource-poor locations where patients are managed. In this retrospective study from Queensland, Australia, 22/144 (15%) men with melioidosis had a radiologically confirmed prostatic abscess. The absence of urinary symptoms had a negative predictive value (NPV) (95% confidence interval [CI]) for prostatic abscess of 96% (90-99%), whereas a urinary leukocyte count of < 50 × 10(6)/L had an NPV (95% CI) of 100% (94-100%)...

Recent World Health Organization (WHO) guidelines recommend antiretroviral therapy (ART) for all HIV-infected people; previously CD4+ T lymphocyte quantification (CD4 count) or clinical staging determined eligibility for children ≥ 5 years old in low- and middle-income countries. We examined positive predictive value (PPV) of a rapid diagnostic test (RDT) algorithm and ART eligibility for hospitalized children with newly diagnosed HIV infection. We enrolled 363 hospitalized Malawian children age 2 months to 16 years with two serial positive HIV RDT from 2013 to 2015...

BACKGROUND: Current reports applying ESPGHAN exception criteria (EEC) to diagnose celiac disease (CD) without duodenal biopsies indicate that a high percentage of patients with CD may be identified when applied correctly in specialized settings. However, application of the EEC in "daily life conditions" at the different levels of medical services is not clear. METHODS: EEC was applied to 130 pediatric patients evaluated for CD at five public hospitals in Santiago, Chile, during 2010-2015...

The unavailability of simple, quick, and sensitive genetic-based molecular diagnostic techniques has become the main driving force for inventing new approaches in the era of quantum dots (QDs): a new class of fluorescent probes with fascinating optical electronic properties. Using the unique size-dependent light-emitting properties of QDs, we have developed a QD-based ultrasensitive technique which removes the necessity for the genetic amplification step required in almost all types of molecular-based diagnostic techniques...

BACKGROUND: A Clostridium difficile-associated risk of death score was recently developed and validated by using a national cohort of both nonsurgical and surgical patients admitted with C difficile infection. However, risk scores specifically derived from surgical cohorts and designed for patients with C difficile infection are currently unavailable. OBJECTIVE: The aim of this study was to develop a risk of death score for patients with C difficile infection who are being considered for total abdominal colectomy because of the failure of medical therapy...

Purpose: Breast cancer is the leading cause of cancer death in women worldwide, with high mortality in low- and middle-income countries because of a lack of detection, diagnosis, and treatment. With mammography unavailable, ultrasound offers an alternative for downstaging. The literature reports successful training in various domains, but a focus on the breast is novel. We assessed the feasibility (knowledge acquisition, perceived usefulness, and self-efficacy) of breast ultrasound training for nonphysician providers...

Transient elastography (TE) is accurate in staging fibrosis noninvasively. However, a reliable serum biomarker with comparable accuracy is also important, especially when TE is unreliable/unavailable. Therefore, we aimed to evaluate the diagnostic performance of serum Golgi protein 73 (GP73) for significant fibrosis in patients with chronic HBV infection. A total of 801 patients with chronic liver disease (CLD; 492 chronic HBV infection and 309 non-HBV liver disease) with liver biopsy performance were enrolled...

The clinical diagnosis and treatment of Alzheimer's disease (AD) represent a challenge to clinicians due to the variability of clinical symptomatology as well as the unavailability of reliable diagnostic tests. In this study, the development of a novel electrochemical assay and its potential to detect peripheral blood biomarkers to diagnose AD using plasma immunoglobulins is investigated. The immunosensor employs a gold electrode as the immobilizing substrate, albumin depleted plasma immunoglobulin as the biomarker, and polyclonal rabbit Anti-human immunoglobulin (against IgA, IgG, IgM) as the receptor for plasma conjugation...

Chronic Granulomatous Disease (CGD) is an inherited immunodeficiency disorder affecting the microbicidal function of the phagocytes. It is characterized by susceptibility to recurrent infections leading to significant morbidity and mortality. Antibacterial and antifungal prophylaxis though has significantly reduced the rate and severity of the infections; the breakthrough infections still remain a challenge. Currently allogenic hematopoietic stem cell transplantation is the only curative option which is very expensive and unavailable for many due to lack of suitable donor...

Light microscopy is an essential tool in histological examination of tissue samples. However, the required equipment for a correct and rapid diagnosis is sometimes unavailable. Smartphones and mobile phone networks are widespread, and could be used for diagnostic imaging and telemedicine. Macrovesicular steatosis (MS) is a major risk factor for liver graft failure, and is only assessable by microscopic examination of a frozen tissue section. The aim of this study was to compare the microscopic assessment of MS in liver allograft biopsies by a smartphone with eyepiece adaptor (BLIPS device) to standard light microscopy...

We report a case of fibromatosis demonstrating prostate-specific membrane antigen (PSMA)-positive scan. A 76-year-old man was under assessment because of rising prostate-specific antigen level. Bone scan showed abnormal soft tissue uptake of Tc-MDP adjacent to the right scapula, compatible with a mass in MRI, thereafter. Because of the unavailability of Ga-PSMA scan in our department and also high cost in other centers, the patient underwent Lu-PSMA for more assessment, which revealed PSMA-avid mass. Pathologic examination confirmed the diagnosis of low-grade fibromatosis...
